This study investigated pollutants emissions from filling stations and their impact on the air quality. Gas monitors were employed to identify the different pollutants present in the ambient air of the study areas. The results showed that the most prominent pollutants present in the ambient air are the volatile organic compounds followed by methane, then carbon monoxide. Measurements were taken...

There were 6 severe haze events over a large area of the Yangtze River Delta (YRD) region in January 2013. In this study, based on the hourly concentrations of trace gases and PM2.5 at 10 observation stations (8 city stations, 1 regional background station and 1 island station) during Jan. 1–31, 2013 as well as the concentrations of water-soluble ions at 5 stations (4 city stations and 1 region...

OBJECTIVE To provide effective environmental management for total amount control of atmospheric pollutants. METHODS An atmospheric diffusion model of sulfur dioxide on the surface of the earth was established and tested in Shantou of Guangdong Province on the basis of an overall assessment of regional natural environment, social economic state of development, pollution sources and atmospheric...

Clay minerals modified with organic ions, also known as organoclays, have found applications in a wide range of organic pollution control fields because of their excellent sorption capacity towards organic pollutants. Regeneration of the spent organoclays after the sorption of organic pollutants is of great importance during their application in pollution control. In this review, the reported m...

The rapid industrial development and agricultural growth and the indiscriminate production of pollutants have faced problems for human societies and the environment. Accumulation and pollution of heavy metals in the environment are the main important problems that as a result of human activities through extraction from ore and processing for various applications has led to the release of these ...

Wastewaters are a potential source of pollutants causing serious problems to the environment. Liquid membrane is able to remove contaminants in wastewaters [1], among other techniques such as chemical precipitation, coagulation–flocculation, flotation, ion exchange, electro-oxidation and adsorption [2,3]. It has been given considerable attention by researchers due to its outstanding characteris...
