Contamination by Organochlorine Pesticides from Rivers

by Center for Environment and Energy Research & Studies (CEERS)  (Jan. 1, 2007)

The contamination of organochlorine pesticides (OCPs) from the selected rivers in Okinawa Island was investigated to estimate the current status of pollution in water, plants and surface sediments in these rivers. The Aja River, Asato River, Houtoku River, Kokuba River and Okukubi River were selected for this study. The concentration of the total ...

Carcinogenesis of Synthetic Organic Chemicals in Drinking Water

by American Water Works Association (AWWA)  (Jul. 1, 1981)

Experimental evidence strongly suggests that ingestion of low levels of carcinogenic and mutagenic contaminants in water contribute to the incidence of cancer. Carbon tetrachloride, chloroform, vinyl chloride, chlordane, dieldrin, PCBs, and trihalomethanes are ...

Simplified Resin Sorption for Measuring Selected Contaminants

by American Water Works Association (AWWA)  (Apr. 1, 1976)

In an extensive study initiated at Iowa State University the concentrations of three pesticides, atrazine, DDE, and dieldrin, in various surface, subsurface, and finished waters were measured. Applications and tests of the resin sorption method for monitoring organic contaminants are presented. Gas chromatography, groundwater, water treatment, ...

Adsorption of Toxic and Carcinogenic Compounds from Water

by American Water Works Association (AWWA)  (Apr. 1, 1982)

The Michigan Adsorption Design and Application Model, applied here to seven specific toxic or carcinogenic compounds found in U.S. surface waters and groundwaters, is being used for data synthesis and for simulation and prediction of the performance of carbon beds in removing trace quantities of such compounds under conditions approximating water ...

Case Study of Petrox® Bioaugmentation to Remediate Pesticides in Ground Water to Part Per Trillion Concentrations

by CL Solutions, LLC  (May 24, 2010)

This case study of bioaugmentation demonstrates that Petrox bioaugmentation can achieve the very low remediation goals set for pesticides in ground water – quickly and cost effectively.  After three injections of Petrox®, the contaminant concentrations were reduced by 99% in less than 9 months.  Project highlights are:  ...

Bioremediation replaces “dig and dump” for treatment of pesticides in soil

Historical usage of organochlorine pesticides (OCPs) such as DDT, toxaphene and dieldrin has resulted in long-term soil contamination, because these substances typically do not degrade naturally at significant rates, so sites are still impacted decades after the end of application. For example, DDT use in Canada ended over 30 years ago, but ...

Cattle egrets as a biosentinels of persistent organic pollutants exposure

by NILU - The Norwegian Institute for Air Research  (May 14, 2014)

We investigated selected chlorinated pollutants (β-HCH, γ-HCH, DDDs, DDEs, o,p′-DDT, p,p′-DDT, heptachlor, aldrin, dieldrin, and endrin) in the Lahore and the Sialkot districts of Pakistan, using eggs of cattle egret (Bubulcus ibis) collected during May and June 2007. The pollutant with highest level and frequency was ...

Trends of Chlorinated Organic Contaminants in Great Lakes Trout and Walleye from 1970 to 1998

by Springer  (Nov. 18, 2005)

Abstract  Levels of chlorinated organic contaminants in predator fish have been monitored annually in each of the Great Lakes since the 1970s. This article updates earlier reports with data from 1991 to 1998 for lake trout (Salvelinus namaycush) and (Lake Erie only) walleye (Sander vitreus) to provide a record that now extends nearly 30 ...
