ulatory standard for minimizing potentihealth effects arising from their ingestion in drinking water (5). Other common inorganic anions, such as fluoride, chloride, and sulfate, are considered secondary contaminants and are regulated under the U.S. National Secondary Drinking Water Standards, which are guidelines for taste, color, odor, and certain aesthetic effects (6). Although bromide is not...

Karun River is the largest and most watery river in Iran. This river is the longest river which located just inside Iran and Ahvaz Metropolis drinking water supplied from Karun River as well (fa.alalam.ir). Karun River as the main source of water treatment plants in Ahvaz, like most surface waters affected by various contaminants which caused changes in water quality of the river (www.aww.co.ir...

Clean fresh water is essential to our life. Unfortunately, in our consumer-based economy, a large amounts of wastewater having been generated by industrial plants. Wastewaters produced in many industrial plants often contain organic compounds which are toxic and not amenable to direct biological treatment. These wastewaters must be treated in order to meet the specifications for discharge or fo...

landfill leachates are potential threats for environmental degradation. this study was conducted to determine the leachate quality, to identify the dominant pollutants and to evaluate the leachate pollution potential of an active and closed dumping ground of an uncontrolled municipal solid waste landfill site in kolkata, india using leachate pollution index. the results of the physico-chemical ...

Global increases in consumption of chemical nutrients, application of pesticides, and water withdrawal to enhance agricultural yield have resulted in degraded water quality and reduced water availability. Efforts to safeguard or improve environmental conditions of agroecosystems have usually focused on managing on-farm activities to reduce materials loss and conserve habitat. Another management...

the present study aimed at investigating and estimating the amount of damage caused by waste water pollution of water desalinators in the south pars special zone. the main reasons for conducting this study were to investigate the creation of environmental pollutants as a result of the development and expansion of different industries in the south pars zone, as well as the ecological sensitivity...

Understanding the implications of different management strategies is necessary to identify best conservation trajectories for ecosystems exposed to anthropogenic stressors. For example, science-based risk assessments at large scales are needed to understand efficacy of different vector management approaches aimed at preventing biological invasions associated with commercial shipping. We conduct...

The European Union allows the designation of mixing zones (MZ) adjacent to a punctual discharge. Concentrations one or more substances could exceed environmental quality standards in MZ if rest water body meets standards. However, does not explain how define it. In this paper, simulation is done through two free software, Discharge Test and Visual Plumes. used perform first analysis proposed sc...
