Given the immense risk posed by widespread environmental pollution by inorganic and organic chemicals, novel methods of decontamination and clean-up are required. Owing to the relatively high cost and the non-specificity of conventional techniques, bioremediation is a promising alternative technology for pollutant clean-up. Advances in bioremediation harness molecular, genetic, microbiology, an...

Mangrove ecosystem is a very unique ecosystem in the Earth, which is under threat due to habitat loss, aquaculture expansion, overharvesting and increase of pollution load. In this review paper, world-wide status of mangrove habitat loss, the role of mangrove to act as a sink of pollutants and carbon capture (carbon sequestration), accumulation and biomagnifications of heavy metals is discussed...

Accuracy in trace level clinical or biomedical analyses is of increasing importance as populationbased surveillance is more widely used to address issues of nutritional requirements, environmental exposures, and epidemiological outcomes. Among the uses of such surveillance, evaluation of community exposures from a local arsenic pollution source is one example. Urinary biological monitoring is a...

This contribution regards three fundamental aspects of the urban pollution, sources, diffusion and chemical composition with relative speciation, pointing out the anthropogenic activities and their relationship with the environmental sustainability. The chemical parameters ruled by laws (conventional pollutants) are evidenced together with other species not ruled (no conventional pollutants) bu...

The Border Air Quality and Meteorology Study (BAQS-Met) was an intensive, collaborative field campaign during the summer of 2007 that investigated the effects of transboundary pollution, local pollution, and local meteorology on air quality in southwestern Ontario. This analysis focuses on the measurements of the inorganic constituents of particulate matter with diameter of less than 1 μm (PM1)...

Continuous measurements of meteorological parameters, gaseous pollutants, particulate matters, and the major chemical species in PM2.5 were conducted in urban Hangzhou from 1 September to 30 November 2013 to study the potential sources and formations of PM2.5 pollution. The average PM2.5 concentration was 69 μg ̈m ́3, ~97% higher than the annual concentration limit in the national ambient air qua...

Particulate matter derived from various sources of fuel combustion contains minor to trace amounts of Fe-oxides that can be detected by magnetic measurements. These magnetic particulates can be used as proxies for particulate pollution, since oxide contents are often larger in amounts and may have distinctive magnetic properties, compared to most types of natural dusts. Magnetic particulates ra...

Coastal aquatic ecosystems are increasingly affected by diffuse source nutrient water pollution from agricultural activities in coastal catchments, even though these ecosystems are important from a social, environmental and economic perspective. To warrant sustainable economic development of coastal regions, we need to balance marginal costs from coastal catchment water pollution abatement and ...

introduction: air pollution is one of the problems of the recent century caused by vehicles, industries and other urban activities. the city of yazd faces air pollution due to its high population, vehicular traffic and industrial places around the city. one of the important parameters of air pollution is suspended air particles that have harmful effects on the health of people, plants and objec...
