The analysis and probabilistic health risk assessment of polycyclic aromatic hydrocarbons in vegetables and fruits samples marketed Tehran:Chemometrics
Environmental Health
The aim of current study was to evaluate the polycyclic aromatic hydrocarbons (PAHs) concentration and probabilistic health risk in vegetables and fruits samples of Tehran city, Iran during 2018-2019 using magnetic solid-phase extraction (MSPE)and gas chromatography-mass spectrometry(GC-MS).The...
Analysis of regional heavy PM2.5 pollution events in Beijing-Tianjin-Hebei and the surrounding area in China during 2015–2018
Air Quality
Beijing-Tianjin-Hebei and the surrounding area (BTHS) experiences the most serious PM2.5 pollution in China. To investigate PM2.5 pollution characteristics in regional heavy air pollution, forty-three events in BTHS during 2015–2018 were selected in this study. These regional events generally lasted...
Synthesis of Multi Wall Carbon Nanotubes based on zirconium oxide as supported material and its application as nanosorbent for copper ions removal
Nanomaterials in the environment: applications and effects
Water pollution caused by various toxic contaminants has become one of the world's most serious issues. Nanotechnology has received a lot of attention in recent decades, and various nanomaterials for water remediation have been developed. For this purpose, MWCNTs were directly synthesized using a...
Hydrological behavior of natural springs/streams in mid hills of Chakrata Himalaya, India
Ecosystems and Natural Resources Management
The present study was carried out to understand the hydrological behavior of natural springs/streams in Semalta watershed, Kalsi block, Dehradun. The surface catchment areas of springs/streams were delineated using Survey of India Toposheet (1:50,000 scale) whereas drainage, slope, and land use maps...
Separation of green solvent dimethyl carbonate/methanol azeotropic mixture by pervaporation with polydimethylsiloxane/polyhedral oligomeric silsesquioxane composite membrane
Air Quality
A composite active layer was prepared by cage type polyhedral oligomeric silsesquioxane (POSS) and polydimethylsiloxane (PDMS) and was combined with polyacrylonitrile (PAN) porous support layer to form pervaporation (PV) membrane, which was used in the PV membrane separation of dimethyl carbonate...
Cadmium biosorption potential and kinetic behavior of endophytic Fusarium verticillioides and its green synthesized silver nanoparticles (GSNPs)
Environmental Toxicology and Biogeochemistry of Ecosystems
Silver nanoparticles (GSNPs) were synthesized from extracellular metabolites of endophytic isolates of Fusarium verticillioides (KT587649) to evaluate their efficiency as new biosorbent agents for the exclusion of cadmium Cd (II) from aquatic systems. The GSNPs were characterized through X-ray...
Performance of combined persulfate and tannin for the treatment of anaerobically treated palm oil mill effluent
Water and Wastewater Treatment
The current research was aimed to investigate the performance of combined persulfate oxidation process and tannin via coagulation-flocculation processes as a post treatment of anaerobically treated palm oil mill effluent (AnT-POME). Different dosages of sodium persulfate (Na2S2O8, 238 g/mol) 0.1 (w...
Impact of Blackwater Disposal in Erbil City on Municipal Wastewater and Bounded Soil Characteristics with Potential Solutions
Water and Wastewater Treatment
Direct discharge of black water (BW) without treatment to the natural environment causes problems for the environment. The present research aimed to examine the impact of direct disposal of BW on the municipal wastewater (MWW) and surrounded soil characteristics in the BW disposal site in Erbil City...
Treatment of combined coffee processing wastewater using constructed wetland/ Cyperus-ustulatus and Typha-latifolia plants process
Water and Wastewater Treatment
The research investigated wastewater discharges from wet coffee processing plant (WCPP) combined with tap water (TW) treated by using Cyperus-ustulatus plant (P1), Typha-latifolia plant (P2) wetland. The WCPP wastewater was conducted by different combination (100%WW + 0% TW; 75% WW + 25% TW; 50% WW...
New Regression models for Estimation daily temperature of Karachi and its Neural Network analysis
Environmental data analysis and modelling
This study presents the determination of the average daily temperature distribution for Karachi city. Artificial Neural Network (ANN) has been used to predict the average daily temperature of 2018, 2019, and 2020. Two regression models (linear and non-linear) were also developed. These models are...
