The requirement to monitor the chemical quality of water has become one of the major issues in environmental analytics. Ionmobility spectrometry (IMS), a fast, sensitive method traditionally used in security and military applications, is also suitable for environmental analysis and detection of organic pollutants from aqueous matrices, when combined with advantageous methods to isolate analytes...

many of the persistent organic pollutants (pops) with endocrine disrupting properties are monitored regularly by risk assessors with limited resources, where analytical procedures are usually laborious, expensive, and not ecofriendly. moreover, these analyses were frequently advanced aiming one class of pollutants, consequently inefficient to correspond the demand of monitoring a quickly rising...

Using Ecological Floating Bed (EFB) to purify polluted water is a process of ecological restoration at virgin position, as well as a complicated physical, chemical and biological process. Its core is utilizing aquatic plants and root’s microbes to absorb nitrogen and phosphorus elements, degrade organic matter and enrich heavy metal. EFB has been applied to some water pollution control projects...

Abstract: Limited water resources and ensuring access to clean water are critical environmental challenges, especially for the developing world. In particular, rural domestic wastewater has become a significant source for the pollution of freshwater bodies. A modified bio-ecological A2O-wetland system for rural wastewater treatment consisting of a biological unit (anaerobic baffled reactor, ano...

ABSTRACT Surface water samples (river and lake) were collected from the Revelva catchment every summer from 2010 to 2013. This study concerns importance of the use of some analytical techniques for pollutants and parameters determination in Arctic environmental samples based on the example of total organic carbon, phenols, and formaldehyde determination and measurement of pH and electrical cond...

This article presents the results of a transboundary water quality monitoring program at the two Nogales area in the Arizona-Sonora border region. The program was carried out jointly in 1990 by U.S. and Mexican institutions. The results show pollution problems due to deficiencies in Nogales, Sonora municipal sewerage system, causing not only sewage spills in several parts of the city but also c...

Ground and surface water contamination resulting from the leakage of crude oil and refined petroleum products is a serious and growing environmental problem throughout the world. Consequently, a study of the use of electrochemical treatment in the clean-up was undertaken with the aim of reducing the water contamination by aromatic pollutants to more acceptable levels. In the experiments describ...

aims: municipal landfill leachate contains high concentrations of heavy metals, organics, ammonia . t he efficeincy of electrochemically removal of heavy metals from landfill leachate was studied. materials & methods: the leachate was obtained from kahrizak landfill in south of tehran. the experiments were carried out by batch process. the 2liter batch reactor was made of glass. there were eigh...

Crop production models are highly developed to account for different nitrogen, light, temperature and water availability conditions and, in some species, disease or air pollutant effects. There is very limited knowledge on responses of many tropical crops, such as oil palm (Elaeis guineensis), to air pollutants although predictions of these effects are essential for industrial planning in sever...
