sons, except in a limited role of reference for a specific topic. It is an excellent book for the biologist, particularly the aquatic biologist, and is highly recommended for their general use. In addition it is a fine reference for those concerned with developing, establishing, and planning programs of water pollution control. It is unfortunate that the word "control" has been used in the titl...
In response to changing laws as well as increased concern over environmental pollution, there is a current need to examine the best means of disposal of wash water generated by mosquito abatement operations. A study of wash waters from 6 central California mosquito abatement districts shows that herbicide levels were low enough so as not to preclude the use of these waters for recycling back in...
One of the most critical issues faced by chemical industries is reducing environmental impact caused due to pollution, which has resulted in global warming and health issues. Most monitor use Key Performance Indicators (KPIs) control currently done using various KPI’s that are dependent on product they producing. Therefore, a study conducted systematic literature review (SLR) focused articles p...
Estrogenic pollution and its control in aquatic systems have drawn substantial attention around the world. The chemical and biological assessment approaches currently utilized in the laboratory or field cannot give an integrated assessment of the pollution when used separately. In this study, in situ chemical and biological methods were combined to detect pollution in a water recycling system. ...
From the first awareness of agricultural sources of water pollution in the US in the 1960s, we finally see in the 1990s a commitment at the national level for agricultural non-point source (NPS) pollution control. This has been occasioned by a growing awareness that, with point sources of some pollutants largely controlled by waste-water treatment, greater attention must be paid to NPS pollutio...
