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...

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...

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...

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...

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...

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...

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...

Batch adsorption experiments have been conducted to investigate the adsorption properties of the calcined sugar scum powder for methylene blue (MB) and methyl orange (MO) as models for cationic and anionic dyes. The kinetic and equilibrium adsorption have been investigated to determine the...

(E)-2-((pyren-1-ylmethylene)amino)phenol (3) containing pyrene linked through an imine bond to a phenol unit was synthesized and its Fe-complex 4 was prepared. The complex 4 is characterized by infrared (IR), x-ray diffraction (XRD) and UV-Vis spectroscopy techniques. The synthesized complex was...

This study is aimed at quantifying the contribution of small urban green spaces to mitigate adverse bioclimatic conditions within the urban environment of Athens during summer and investigate their thermal profile during a warm, a cold and a transitional period. Six green and non-green sites inside...

Regular water treatment-plant (WTP) comprises of a number of units. Of course, problems exist throughout design and operation of the WTP units. Consequently, the current re-search aimed to minimize the shortcomings of the coagulation, sedimentation, and the adsorption methods through applying...

Aim of the study is to examine the potential utilization of satellite precipitation data to estimate the peak discharges of flash floods in ungauged Mediterranean watersheds. Cumulative precipitation heights from local rain gauge and the GPM-IMERG were correlated in a scatter plot. The calculated...

The development of magnetic sorbent for dispersive solid-phase micro-extraction (DmSPE) often requires lengthy multi-step reactions. This research revealed a simplified method for preparing magnetic sorbent for the DmSPE using poly(4-vinylphenol) (PVP). The magnetic sorbent (PVP@MNP) was prepared by...

The current study investigates the ability of Nano magnetite as an adsorbent to remove organic materials from oilfield-produced water (PW). The effect of several variables on the removal procedure was investigated, such as nano magnetite dose, pH of solution and adsorption period. The adsorbent was...

Nowadays, breast cancer is considered to be one of the most prevalent diseases worldwide, this initiated interest and growing demand for taxol production in large quantities. The limited availability of traditional taxol production from the Pacific yew trees has encouraged research into the...

Natural products have always been appreciated due to the awareness about environmental standards for global health by using green technologies in their isolation and extraction. Thereupon natural dyes have been used in all fields due to having ecofriendly, therapeutic and aesthetic nature. For the...

Chromium is a common heavy metal pollutant found in industrial wastewaters which may pollute agricultural soils through groundwater and watering. Phytoremediation is an economical and highly applicable method for removal of pollutants from agricultural soils. This research was carried out for the...

The zoning of environmental noise function is aimed to provide a good acoustic environment for people. With the acceleration of China’s urbanization, the zoning of environmental noise function has been widely conducted across the country, and many first-and second-tier cities have even made multiple...

Urbanization, industrialization and economic growth have considerable challenged the orientation of waste management policies and practices. Intrinsically, major concerns appear in urban environments, as they receive increased volumes of waste, which in turn pose threats for the environment and...

Rainfall is one of the primary sources of chemical inputs in forest ecosystems, and the basis of forest nutrient cycling. Urban trees play an important role in the built environment, reducing the rainfall reaching the ground by rainfall interception. To explore the variations of nutrient cycling and...
