There is rapidly growing interest in the use of market-based (MB) instruments in environmental policy. The papers in this session discuss three relatively new areas for such policies: groundwater contamination, nonpoint source surface-water pollution and carbon sequestration. The papers point out the potential for MB policies in these areas, but significant challenges remain. This comment highl...

Testate amoebae (TA) associated with terrestrial mosses are increasingly used in ecological and ecotoxicological studies. The TA community is sensitive to changes in its environment (climate change, metal or gas pollution). In this study, a “bryophyte-TA” microsystem was investigated as an indicator of dry particulate deposition and NO2 atmospheric concentration over an 8-month period in rural,...

The accurate estimation of deposits adhering on insulators is of great significance to prevent pollution flashovers which cause huge costs worldwide. Researchers have developed sensors using different technologies to monitor insulator contamination on a fine time scale. However, there is lack of analysis of these data to reveal spatial and temporal characteristics of insulator contamination, an...

background and purpose: in the process of rapid urbanization and industrialization in developing countries, environmental pollution is a major concern. one of the fastest growing problems of environmental pollution is an excessive intake of lead in urban soils. lead concentrations in urban soil may result from human activities such as vehicle emissions and industrial activities. this study aime...

This study characterizes the leachates quality of an active dumpsite in Warri, Delta State and also analyses its contamination or pollution potential. Leachate Pollution Index (LPI) a tool for quantifying pollution potential of leachates generated from dumpsites has been used to quantify the leachates contamination potential of the dumpsite. The LPI values for the different sample locations L1,...

Water and sediment samples have been collected from five different stations, located along Djendjen River between February and June, 2016 so that the concentrations of Cd, Ni, Zn, and Cu could be determined. The extent of the sediment pollution has been assessed, using the multiple pollution indices, namely Contamination Factor (CF), Pollution Load Index (PLI), and the geoaccumulation index (Ig...

Legacy lead (Pb) contamination from sport shooting activities is a well-known hazard. Assessing the risk this contamination presents to the environment and public health requires a detailed understanding of its spatial distribution, yet our knowledge in this area is limited, especially for wetland shooting ranges. In this study, we analyzed 1351 sediment samples from 456 surficial (0-5 cm) loca...

River bottom sediments and soils were collected from the industrialized Thur River basin (north-eastern France) to assess mercury contamination. The regional geochemical background level of total mercury was evaluated to calculate mercury contamination factors (Fc) in soils and river bottom sediments. Our estimate of the mean background mercury levels in river sediments and soils, not affected ...
