Trinidad is a small island developing state caught between the need to engage rapid development while respecting and preserving the environment. This study assessed citizens' education needs related to the environmental laws of Trinidad and Tobago. It focused on a densely populated, at- risk area of the country referred to as the East-West (E-W) corridor. Two hundred (200) persons living along ...

the purpose of this research was to investigate the attitude of vegetable growers towards sources of soil pollution in ray county. the study consisted of all vegetable growers (n=700) in ray county, located in tehran province, from which 70 vegetable growers were selected through random sampling technique. a planned questionnaire was used as the main instrument to collect data. the content vali...

The progressive development of civilization and intensive industrialization has contributed to the global pollution of the natural environment by heavy metals, especially the soil. Degraded soils generally contain less organic matter, and thus, their homeostasis is more often disturbed, which in turn manifests in changes in biological and physicochemical properties of the soil. Therefore, new p...

Background: High concentrations of various heavy metals of mine tailings can easily contaminate the environment. Such materials need monitoring and remediation to prevent them from polluting the environment and food chain. Materials & Methods: The concentrations of certain metals were evaluated in the soil samples at Sorkheh and Mazraeh copper mining areas in northwestern Iran, using three r...

introduction the current environmental challenges one of the main concern of is humanity. the issue of when more added concern has been associated with complications. research suggests the environmental challenges are rooted in factors in the different levels of global, regional and local levels are considered. in this case although many studies have been in different aspects of urban environme...

Denitrification is one of the most important soil microbial processes leading to the production of nitrous oxide (N2O). The potential changes with metal pollution in soil microbial community for N2O production and reduction are not well addressed. In this study, topsoil samples were collected both from polluted and non-polluted rice paddy fields and denitrifier communities were characterized wi...

Heavy metals and dyes are major contributors in contamination of water streams. These contaminants enter into our eco- system, thus posing a significant threat to public health, ecological equilibrium and environment. Thus a combined discharge of these contaminants results in water pollution with high chemical oxygen demand, biological oxygen demand, color, particulate matter, suspended particl...

The Environmental Integrity Project (EIP) appreciates the opportunity to submit comments on the U.S. Environmental Protection Agency’s (EPA) draft “Emission Estimation Protocol for Petroleum Refineries” (Protocol) posted for public comment on the Clearinghouse for Inventories and Emissions Factors (CHIEF) website on December 23, 2009. Petroleum refineries are a major source of air pollution in ...
