A study was carried out to investigate the effects of meteorological conditions on atmospheric pollutant concentrations in a complex area. In general serious pollution episodes in the urban and suburban environment are not directly caused by sudden increases in the emission of pollutants but results from unfavorable meteorological conditions, These unfavorable conditions may reduce the ability ...

The soil and water contaminations are frequently occurred by toxic heavy metals and organic pollutants as a consequence of human activities become a key concern in environmental and health problem. Several toxic metals (Cd, Cu, Hg, Pb, Mn, As, Ni, Zn, etc.) from industrial wastewater and other human activities are directly or indirectly released into the environment. Unlike organic contaminants...

Oil contamination in the soil has been a major threat to the environment because of the poor solubility. Crude oil can be accidentally or deliberately released into the environment leads to serious pollution problems (Trindale et al., 2005). Bioremediation is a waste management technique that involves the use of the organisms to remove or neutralize pollutants from a contaminated site. An alter...

Bioremediation refers to the use of organisms to remove environmental pollutants. Besides identifying different new plasmids capable of degrading environmental pollutants, many attempts have been taken by the genetic engineers to enhance the bioremediation potential of different microorganisms. Escherichia coli was engineered to convert chlorinated solvents such as trichloro ethylene and the hi...

air pollution is one of the major threats to environment in the present time. increase in degree of urbanization is a major cause of this air pollution. due to urbanization, vehicular activities are continuously increasing at a tremendous rate. mobile or vehicular pollution is predominantly degrading the air quality worldwide. thus, air quality management is necessary for dealing with this seve...

The rapid screening and sensitive monitoring of environmental pollutants, such as pesticides, persistent organic pollutants (POPs), endocrine disrupting chemicals (EDCs), explosives, and toxins, is indeed essential to ensure environmental quality, and therefore, human health. Until recently, the quantification of most contaminants has been limited to the traditional chromato‐ graphic and spectr...

Environmental management is becoming increasingly dependent on quantitative analysis of environmental and health risks associated with exposure to chemical contaminants. Exposure to chemical pollutants can occur via primary pathways (e.g., inhalation of polluted air or drinking contaminated water) and/or secondary pathways (e.g., ingestion of contaminated food) and therefore requires informatio...

Chemical pollution of the environment has become a major source of concern. Studies on degradation of organic compounds have shown that some microorganisms are extremely versatile at catabolizing recalcitrant molecules. By harnessing this catabolic potential, it is possible to bioremediate some chemically contaminated environmental systems. Composting matrices and composts are rich sources of x...

The pink shrimp Farfantepenaeus duorarum may acquire pollutants, helminths and symbionts from their environment. Statistical associations were studied between the symbionts and helminths of F. duorarum and pollutants in sediments, water and shrimps in Campeche Sound, Mexico. The study area spatially overlapped between offshore oil platforms and natural shrimp mating grounds. Spatial autocorrela...

A variety of multidimensional anthropogenic activities, especially of industrial level, are contaminating our aquatic and terrestrial environments with a variety of metallic and non-metallic pollutants. The metallic and non-metallic pollutants addressed specifically in this review are heavy metals and various compound forms of sulfates, respectively. Direct and indirect deleterious effects of t...
