The model is based on decomposition of finite layers in semi-infinite groundwater reservoir. A constant pollutant source is injected at the input boundary of the uppermost layer (UML) of the landfill. At the intermediate inlet boundary, some average value for the longitudinal exchange of the input source concentration in each sub-layer is considered from the previous layer. Initially, the aquifer is not solute free in each sub layer that means some constant background contaminant concentration exists. In each sub layer, concentration gradient is assumed to be zero at the extreme boundary. The linear sorption and first orders decay terms are considered to model the groundwater pollution in multilayer aquifer. The Laplace transform technique is adopted to solve one-dimensional (1D) advection-dispersion equation (ADE). This approach is helpful to understand the solute migration in finite sub layers. The results are elucidated for the different time periods to examine the peak of pollutant concentration level in geological formations.https://jpoll.ut.ac.ir/article_80600_c75737ddbf3b15bda52c7ce17a9a6393.pdfUniversity Of Tehran PressPollution2383-451X7220210401Do Technological Innovation And Renewable Energy Consumption in Japan Important For Consumption-Based Carbon Emissions?2752918060110.22059/poll.2020.312886.925ENTomiwa SundayAdebayoFaculty of Economics and Administrative Science, Cyprus International University, Nicosia, Northern Cyprus, Mersin 10-TurkeyIbrahimAdesolaSchool of Computing and Technology, Eastern Mediterranean University, Famagusta, Northern Cyprus, Mersin 10-TurkeyModupeOyebanjiFaculty of Economics and Administrative Science, European University of Lefke, Northern Cyprus, Mersin 10-TurkeyOseyenbhin SundayOsemeahonManagement Information Systems, Cyprus International University, Nicosia, Northern Cyprus, Mersin 10-TurkeyJournal Article20201031With growing global warming issues, the association between technological innovation and environmental pollution has created significant debate in recent years. This paper examines the long-run and causal impact of technological innovation, economic growth, and renewable energy on consumption-based carbon emissions in Japan. The study utilized quarterly data spanning between 1990 and 2015. The study utilized recent econometrics techniques such as Maki co-integration, ARDL bunds test, FMOLS, DOLS, and frequency domain causality techniques. To the author's understanding, no prior studies have been conducted in Japan using consumption-based carbon emissions as a proxy of environmental degradation. Thus, this empirical analysis contributes to the literature. The findings from the ARDL bounds and Maki co-integration tests revealed evidence of co-integration among the series. The results of FMOLS and DOLS reveal that both renewable energy and technological innovation improve the environmental quality, while economic growth harms the quality of the environment. The results of the frequency-domain causality technique reveal that technological innovation, renewable energy, and economic growth can significantly predict consumption-based carbon emissions in Japan. Based on these outcomes, we suggested that Japan's government should be careful when formulating policies that trigger growth, which will have a detrimental impact on the environmental quality. Our empirical outcome also revealed that any policy that encourages renewable energy should be encouraged since it enhances environmental quality.https://jpoll.ut.ac.ir/article_80601_1113ac54cd60d91a5ed2febaff93036e.pdfUniversity Of Tehran PressPollution2383-451X7220210401The Impact of RDF Valorization on the Leachate Quality and on Emissions from Cement Kiln (Case Study of a Region in Morocco)2933078060210.22059/poll.2021.309346.890ENAbdellahOuigmaneTeam of Applied Spectro-Chemometry and Environment.

The co-incineration of refuse derived fuel (RDF) has shown several economic and environmental advantages. The objective of this research is to assess the impact of RDF recovery on leachate quality using leachate tests and calculation of greenhouse gases (GHG) reduction in the kilns of a cement plant. The qualitative results of the eluate show that there is an impact on leachate quality depending on the type of waste. The values of the chemical oxygen demand (COD), biological oxygen demand (BOD5), electrical conductivity and pH of the leachate from the raw waste after 120 hours of leaching are 29.33 gO2/kg DM, 14.00 g O2/kg DM, 4.27 ms/cm and 7.57. On the other hand, the values of the same quality parameters of the eluate generated by the waste without RDF are 19.33 g O2/kg DM, 20.67 g O2/kg DM, 2.77 ms/cm and 7.13; respectively. The calculation of GHG reduction shows that the substitution of 83,000 tonnes per year of petroleum coke by 15% of RDF (25,493 tonnes per year) can reduces 28,970 tCO2 eq.https://jpoll.ut.ac.ir/article_80602_f2779329a292292c5e2ea36fc1183cea.pdfUniversity Of Tehran PressPollution2383-451X7220210401Efficacy of Photocatalytic HEPA Filter on Reducing Bacteria and Fungi Spores in the Presence of UVC and UVA Lights3093198060310.22059/poll.2021.311399.916ENTaherehMousaviDepartment of Occupational Health Engineering, School of Public Health, Tehran University of Medical Sciences, Tehran, IranFaridehGolbabaeiDepartment of Occupational Health Engineering, School of Public Health, Tehran University of Medical Sciences, Tehran, IranMehrdad HelmiKohneshahriDepartment of Occupational Health Engineering, School of Public Health, Tehran University of Medical Sciences, Tehran, IranMohammad RezaPourmandDepartment of Pathobiology, School of Public Health, Tehran University of Medical Sciences, Tehran, IranSassanRezaieDepartment of Parasitology and Mycology, School of Public Health, Tehran University of Medical Sciences, Tehran, IranMostafaHosseiniDepartment of Epidemiology and Biostatistics, School of Public Health, Tehran University of Medical Sciences, Tehran, IranAliKarimiDepartment of Occupational Health Engineering, School of Public Health, Tehran University of Medical Sciences, Tehran, IranJournal Article20201006The Indoor Air Quality (IAQ) of a hospital is very important to properly protect both patients and the staff against hospital infections. The present study aims at evaluating the efficiency of photocatalytic filters as well as the impact of important factors such as the type of UV wavelength (UVC, UVA) with different intensities and loading rates of TiO2 in HEPA Filters on reducing airborne microorganisms. For so doing, it has prepared photocatalytic filters by dipping them into 2% and 4% titanium dioxide suspensions as low and high loading, respectively. The experiments have been carried out on four species’ microorganisms, namely Epidermidis, Subtilis, Niger, and Penicillium. Fungi and bacteria suspensions have been prepared with concentrations of 106, 107 CFU/m3, respectively. In terms of microorganism removal, the efficiency of HEPA filters in both types of TiO2 loading and UVC and UVA radiations with two intensities at three times intervals (60, 90, and 120 min) have been investigated. Results show that lower penetration microorganism belong to PCO (TiO2 + UV), compared to photolysis (UV alone) at all intervals of UV radiation. TiO2 loading has no significant effect on percentage removal in all microorganisms. The percentage penetration of microorganisms under UVC radiation is lower than UVA radiation. Also, increasing the radiation intensity in both types of UV shows that it has higher effectiveness for removing bacteria and fungi. Therefore, the use of photocatalytic HEPA filters with UVC radiation can play an influential role in reduction of the microorganisms in different places such as hospitals, cleanrooms, etc.https://jpoll.ut.ac.ir/article_80603_80e728e7546cd2002b6652f192713c3f.pdfUniversity Of Tehran PressPollution2383-451X7220210401Efficiency of humic acid from various organic sources for reducing hexavalent chromium in aqueous solutions3213318060410.22059/poll.2021.308924.880ENParisaMoradkhaniSoil Science Department, Faculty of Agriculture, University of Tabriz, P.O.

HAs were extracted from leonardite, peat moss, peat, cocopeat, coal, common char, biochar, vermicompost and sewage sludge. Some chemical and spectral characteristics of the extracted HAs were measured. Then, the reducing efficiency of HAs was measured and its relationship with the determined properties was investigated. To measure the reducing efficiency of HAs, a concentration of 0.1 mM CrVI (as potassium dichromate) in a sodium nitrate solution (0.03M) with a pH of 2 and in the presence of 100 mg of HA per liter was used. The experiment was conducted in three ways (symbolized by E1, E2 and E3). They differ from each other with respect to the method of phosphate buffer addition to release CrVI ions adsorbed by HA. This buffer was added to an aliquot of final extract, to the whole volume of final suspension and to initial solution containing CrVI in experiments E1, E2 and E3, respectively. According to the results, the CrVI reducing efficiency depends not only on the nature of HA but on the method of experiment. The minimum reducing efficiency was observed for common char using experiment E2 and the maximum value was for biochar and cocopeat in all three experiments. The results showed that the two factors of ΔlogK and maximum reducing efficiency in the format of a multiple regression had a significant relationship with CrVI reducing efficiency of HAs.https://jpoll.ut.ac.ir/article_80604_639a6b8a0a4756ed13f5da068d45304a.pdfUniversity Of Tehran PressPollution2383-451X7220210401Studying Some Blood Parameters of Otolithes ruber (Schneider, 1801) in Cold and Warm Seasons as an Indicator of Pollution in Musa Creek3333408060510.22059/poll.2021.317422.998ENHamidehGhasemiDepartment of Marine Biology, Faculty of Marine Science, Khorramshahr University of Marine Science and Technology, Khorramshahr, IranRahimAbdiDepartment of Marine Biology, Faculty of Marine Science, Khorramshahr University of Marine Science and Technology, Khorramshahr, IranAbdulmajedDoraghiDepartment of Marine Biology, Faculty of Marine Science, Khorramshahr University of Marine Science and Technology, Khorramshahr, IranNeginSalamatDepartment of Marine Biology, Faculty of Marine Science, Khorramshahr University of Marine Science and Technology, Khorramshahr, IranMohammad AliSalari-AliabadiDepartment of Marine Biology, Faculty of Marine Science, Khorramshahr University of Marine Science and Technology, Khorramshahr, IranJournal Article20210117The present study attempts to investigate some blood parameters of Otolithes ruber during different seasons in terms of both temperature and pollution. For so doing it uses 10 specimens, for each station and season, collected from 5 polluted stations, including Petrochemical, Ghanam, Zangi, Douragh, Patil, and Sajafi as the control group, away from pollution in Musa Creek. The fish are anesthetized with 1ml of clove extract per liter. Their blood samples are taken immediately from the caudal vein, using a heparinized syringe. Afterwards, the serum is separated in a centrifuge with a speed of 6000 rpm for 2 minutes. The desired factors are measured by the Mindray BS200 auto-analyzer and the total protein level, by Bradford's usual laboratory methods. Results show that AST, ALT, ALP, Glucose, and Triglycerides have increased in more polluted stations (P≤0.05). In sheer contrast, total protein and Albumin have decreased as pollution grows (P≥0.05). According to this study, environmental water pollution of the fish has a large impact on the concentration of measured blood parameters, whereas the influence of seasonal changes on most of them is low.https://jpoll.ut.ac.ir/article_80605_643c2e0f09ff755df4f81a371fc47100.pdfUniversity Of Tehran PressPollution2383-451X7220210401Batch and Column Studies on Nickle and Cadmium Removal Using Iranian Clay-based Geopolymer3413548060610.22059/poll.2021.310600.905ENSomayehBakhtiariDepartment of Civil Engineering, Sirjan University of Technology, Sirjan, IranAsmaZeidabadinejadDepartment of Civil Engineering, Sirjan University of Technology, Sirjan, IranHaniehAbbaslouDepartment of Civil Engineering, Sirjan University of Technology, Sirjan, IranAlirezaGhanizadehDepartment of Civil Engineering, Sirjan University of Technology, Sirjan, IranJournal Article20200923The production rate of industrial and agricultural waste is increasing due to population growth. Soil is the most important receiver of industrial and agricultural waste. Contaminants such as heavy metals in various waste after reception by the soil, immediately become part of the cycle that has different impacts on the environment. Geopolymer, as a chemical stabilizer has the potential to stabilize heavy metals in the soil. In this research, several geopolymers for the stabilization of heavy metals in soil were synthesized. Silicon dioxide (SiO2) and aluminosilicate (Al2SiO4) must be used to produce the geopolymers. Rice husk ash was used as the SiO2 source. Also, Iranian zeolite and sepiolite, and red clay soil were utilized as the source of Al2SiO4. The synthesized geopolymers were investigated for the adsorption of nickel and cadmium. Also, batch and column studies of using geopolymers for the chemical stabilization of heavy metals in soil were conducted. The results revealed a high adsorption capacity of the geopolymers. The zeolite, sepiolite, and red clay geopolymer-soil samples adsorbed 100% of the heavy metals (i.e., Ni and Cd) at a concentration of 100 ppm. The zeolite geopolymer adsorbent adsorbed 57% and 96% of Ni and Cd at a concentration of 1000 ppm, respectively. In general, it was concluded that the use of geopolymer compounds in soils with high heavy metal adsorption capacity could be an efficient approach to prevent groundwater resource pollution.https://jpoll.ut.ac.ir/article_80606_c8fb50d0e40b8c376b7c1c583212ee02.pdfUniversity Of Tehran PressPollution2383-451X7220210401Effect of Biochar Amended Vermicomposting of Food and Beverage Industry Sludge along with Cow dung and Seed Germination Bioassay3553658060710.22059/poll.2021.315530.961ENUmme FarihaTasnimDepartment of Environmental Sciences, Jahangirnagar University, Dhaka-1342MashuraShammiDepartment of Environmental Sciences, Jahangirnagar University, Dhaka-1342Md.

This research aimed to investigate the effect of biochar amendment on vermicomposting of the food and beverage industry sludge (FBIS) and cow dung (CD) in a different ratio using earthworm Eisenia fetida. We had further investigated the survival rate of E. fetida and the cocoon productions after 35 days of the vermicomposting. Besides, we have also evaluated the seed germination bioassay using Malabar spinach (Basella alba) to determine the toxicity and maturity of produced compost. The survival and cocoon production of E. fetida were higher in vermicompost amended with 10% biochar. Vermicomposting with biochar resulted in a slight pH shift. Reduction in organic carbon (OC) percentage not so significant in biochar added FBIS and CD. An increase in phosphorus and potassium content and a decrease in nitrogen percentage observed; vermicomposting with biochar resulted in higher seed germination, root elongation, and germination index than vermicomposting without biochar.https://jpoll.ut.ac.ir/article_80607_74ca92ae1258a594d0c6831d9e6b62b9.pdfUniversity Of Tehran PressPollution2383-451X7220210401Effects of Prenatal Exposure to Urea Fertilizer on the Angiogenesis, Body Growth, and Liver Structure of Duck (Anas platyrhynchos) Embryos3673758067810.22059/poll.2021.303119.819ENJashinRosalDepartment of Biology, Caraga State University, Butuan City 8600, PhilippinesChennieSolaniaDepartment of Biology, Caraga State University, Butuan City 8600, PhilippinesMariel QueenieAganSenior High School, Caraga State University, Butuan City 8600, PhilippinesDonaldMondeaSenior High School, Caraga State University, Butuan City 8600, PhilippinesBruceVillaSenior High School, Caraga State University, Butuan City 8600, PhilippinesDaniljunSanchezSenior High School, Caraga State University, Butuan City 8600, PhilippinesJournal Article20200519The agricultural sector uses fertilizers such as urea to add more nutrients to the soil needed for plant growth. Although it is cost-effective in crop production, indiscriminate use of nitrate-based fertilizer may result in behavioural, morphological, and physiological alterations on non-target organisms. This study determined the angiogenesis activity in the chorioallantoic membrane of urea-exposed duck embryos. It also investigated the weight, morphometries, and liver histopathology to gather more information on urea fertilizer's toxicity. It was observed that urea promoted angiogenesis in the CAM of duck embryos, especially at higher concentrations (P<0.05). Embryos treated with urea resulted in an alteration of the head-beak length (P<0.05). However, weight, crown-rump length, forelimb length, and hind limb length were not affected. The developing liver of urea-treated embryos showed distortion of the central vein shape and had larger sinusoidal spaces. The presence of Kupffer cells and lipid droplets were observed in the treated section. Congestion of blood cells, haemorrhage, and necrosis of hepatocytes were also observed in the tissue suggesting the extent of damage caused by the fertilizer. The findings of this study showed multiple developmental effects of urea on duck embryos. Further investigations are needed to shed more light on the toxicity of urea fertilizer on vertebrates.https://jpoll.ut.ac.ir/article_80678_e7c33d9d98867546bd55daaa74de8dd6.pdfUniversity Of Tehran PressPollution2383-451X7220210401Extraction of Keratin from Human Hair Waste as Adsorbent: Characterization, Thermodynamic and Kinetic Study for Removal of Chromium (VI) ions3773938067910.22059/poll.2021.313734.937ENFereshtehAbbasiDepartment of Chemistry, Ilam Branch, Islamic Azad University, Ilam, IranAbdolhadiFarrokhniaDepartment of Chemistry, College of Science, Shahid Chamran University of Ahvaz, Ahvaz, IranZahraAbbasiFaculty of Science, Ilam University, P.O.Box 69315516, Ilam.

The characterization of keratin nanoparticles was performed applying Transmission electron microscopy (TEM), Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and X-Ray diffraction (XRD). The average diameter of keratin nanoparticles was found to be 63.7 nm, using particle size analyzer. Subsequently, the keratin nanoparticles were employed for Cr (VI) ions adsorption. The batch experiment was carried out to find the optimum conditions; i.e. contact time, pH, adsorbent dose and initial concentration of Cr (VI) ions. The adsorption capacity was extremely pH-dependent, and the maximum adsorption of Cr (VI) happened in the acidic pH range. The results demonstrated that the maximum adsorption capacity, obtained in acidic pH, was 161.29 mg/g. The equilibrium data were well fitted by Freundlich isotherm. The kinetic studies were performed with the Lagergren’s first-order, Pseudo-second order, Elovich, and Intra-particle diffusion models. In this sense, in order to describe kinetic data, we came to this understanding that Pseudo-second order model was the best choice. The thermodynamic parameters of the adsorption process indicated that the Cr (VI) adsorption on keratin nanoparticles is endothermic and spontaneous.https://jpoll.ut.ac.ir/article_80679_ec12659764391fad03daae75b6875fa2.pdfUniversity Of Tehran PressPollution2383-451X7220210401Carcinogenic and Non-carcinogenic Health Risk Assessment of Heavy Metals in Ground Drinking Water Wells of Bandar Abbas3954048068010.22059/poll.2021.317359.995ENHamidrezaFarimani RaadSchool of Environment, College of Engineering, University of Tehran, P.O.

The first site presented the ‘Polluted site’, which is situated in the oasis close to the industrial area. While, the second site referred to the ‘Control site’ located at 37 km from the industrial area. Using HPLC ES-MS, 21 phenols were identified and quantified in methanol extract from pomegranate fruit peel. The results showed that various phytochemical substances, including phenols acids and flavonoids, were identified and quantified in the peel extract. The polyphenols content and the flavonoids contents in peel obtained from polluted site were higher than that collected from the control site. The concentrations of the identified polyphenols were ranged between 0.39 and 7803.68 mg/ kg DW. The stimulation of some free phenolic compounds such syringic acid, transfrulic acid, epicatechin, rutin and quercetin was enregistred only in peel collected from contaminated environment. The quali-qualitative changes between sites are probably related to the difference in the air quality. The increase of polyphenols could be implicated during adaptive mechanisms under air pollution.

The greater PPy-CS/Sn-doped TiO2 nanocoposite particle diameter indicates that the polymers cover the Sn-doped TiO2 nanoparticles, which leads to higher in the diameter of the particles. The adsorption efficiency of Sn-doped TiO2/AC was higher than that of PPy-CS/Sn-doped TiO2 sample due to its smaller particle size which resulted in a higher surface area which provides more adsorption sites. However, both samples showed remarkable adsorption capacity, where the adsorption capacity of Sn-doped TiO2/AC and PPy-CS/Sn-doped TiO2 were 104 and 103 mg/g, respectively.https://jpoll.ut.ac.ir/article_80686_54089eacd25b66deb78097294877344e.pdfUniversity Of Tehran PressPollution2383-451X7220210401Water Quality Assessment in Urban Wetlands and Suitability for Fish Habitat: A Case Study4574678068710.22059/poll.2021.317769.1005ENArohiDixitSchool of Environmental Sciences, Jawaharlal Nehru University, New Delhi – 110067, IndiaNeelamSiva SiddaiahSchool of Environmental Sciences, Jawaharlal Nehru University, New Delhi – 110067, IndiaJogindarSingh ChauhanCentre for the Study of Regional Development, Jawaharlal Nehru University, New Delhi – 110067, IndiaWaseemUllah KhanUniversity Polytechnic, Jamia Millia Islamia, New Delhi-110025, IndiaJournal Article20210113In this study, water from three urban wetlands of Gurugram – Sultanpur (WS), Damdama (WD), and Basai (WB), was studied for various physicochemical parameters to assess their suitability for the healthy survival of fishes and the results were compared with the limits of these parameters for fish farming. The parameters studied were colour, temperature, pH, alkalinity, hardness, Ca2+- Mg2+ ratio, NO3-, Cl-, SO42-, PO43-, and heavy metals (Fe, Mn, Cr, Cu, Zn, Ni and Pb). The results of the study indicate the majority of studied parameters are beyond the desirable limits in WB; thus, water is most unsuitable for fishes in WB. WB is unsuitable for parameters: colour, alkalinity, hardness, Ca -Mg ratio, NO3-, Cl-, SO42-, PO43-, Cr, Cu, Fe, Mn, Ni and Zn. WS needs consideration for temperature, NO3-, Cu, Ni and Zn, whereas WD needs improvement in temperature, TDS, NO3-, Cr, Cu, Fe, Mn, Ni and Zn concentration for better fish growth. Most of the parameters are high in summer as compared to winter, which is due to the dilution after rainfall. Hence, we recommend timely action for effective measures to improve the water quality of wetlands and their regular monitoring for improved fish habitat.https://jpoll.ut.ac.ir/article_80687_c3551019e4e5562faed26a167dc7a71f.pdfUniversity Of Tehran PressPollution2383-451X7220210401Concentrations and Sources of Aliphatic and Aromatic Hydrocarbons in Babolsar Coastal Sediments in the Caspian Sea4694798068810.22059/poll.2021.318623.1017ENNasimTaghaviSchool of Environment, College of Engineering, University of Tehran, Tehran, IranNasserHadjizadeh ZakerSchool of Environment, College of Engineering, University of Tehran, Tehran, IranPardisBiglarbeigiSchool of Engineering, Ulster University, Shore road, Newtownabbey, UKJournal Article20210103This paper presents concentrations and sources of Aliphatic and Aromatic Hydrocarbons in the sediments from Babolsar coastal area and the inlet of Babolrood River in the southern side of the Caspian Sea. The concentration of hydrocarbons in 13 sediment samples from the study area were measured by gas chromatography (GC). Total Petroleum Hydrocarbon (TPH) concentrations in sediment samples in the coastal area ranged from 115 to 201 μg/g. In the inlet samples, TPH concentrations were close to each other and ranged from 294 to 367 μg/g. The TPH results showed moderate level of oil pollution in the study area. Total Polycyclic Aromatic Hydrocarbons (ΣPAHs) concentrations in sediment samples inside the inlet ranged from 498 to 702 ng/g, indicating moderate level of pollution. Concentrations of ΣPAHs in sediment samples in the coastal area ranged from 341 to 1703 ng/g, indicating moderate to less than significant level of pollution. Developed indices for pollutant origins showed that hydrocarbons in all sediment samples collected in the study area had petrogenic origin. The results also showed the Babolrood River as the main source of oil pollution in the sediments in the study area.https://jpoll.ut.ac.ir/article_80688_154041c6cc79ccd8bf0f24c582782fa6.pdfUniversity Of Tehran PressPollution2383-451X7220210401Environmental Pollution Prediction of NOx by Predictive Modelling and Process Analysis in Natural Gas Turbine Power Plants4814948068910.22059/poll.2021.316327.977ENAlanRezazadehApplied Research and Innovation Services, Southern Alberta Institute of Technology, 1301 – 16 Avenue NW, Calgary, AB, Canada T2M 0L40000-0002-4836-7739Journal Article20201231The main objective of this paper is to propose K-Nearest-Neighbor (KNN) algorithm for predicting NOx emissions from natural gas electrical generation turbines. The process of producing electricity is dynamic and rapidly changing due to many factors such as weather and electrical grid requirements. Gas turbine equipment are also a dynamic part of the electricity generation since the equipment characteristics and thermodynamics behavior change as turbines age and equipment degrade gradually. Regular maintenance of turbines are also another dynamic part of the electrical generation process, affecting performance of equipment as parts and components may be upgraded over time. This analysis discovered using KNN, trained on a relatively small dataset produces the most accurate prediction rates in comparison with larger historical datasets. This observation can be explained as KNN finds the historical K nearest neighbor to the current input parameters and approximates a rated average of similar observations as prediction. This paper incorporates ambient weather conditions, electrical output as well as turbine performance factors to build a machine learning model predicting NOx emissions. The model can be used to optimize the operational processes for harmful emissions reduction and increasing overall operational efficiency. Latent algorithms such as Principle Component Algorithms (PCA) have been used for monitoring the equipment performance behavior change which deeply influences process paraments and consequently determines NOx emissions. Typical statistical methods of performance evaluations such as multivariate analysis, clustering and residual analysis have been used throughout the paper.<br /> This paper incorporates ambient weather conditions, electrical output as well as turbine performance factors to build a machine learning model predicting NOx emissions.
