  • Anopheles arabiensis egg treatment with dieldrin for sex separation leaves residues in male adult mosquitoes that can bioaccumulate in goldfish (Carassius auratus auratus)

    The sterile insect technique (SIT) is a biological control tactic that is used as a component of area‐wide integrated pest management (AW‐IPM) programs. The SIT can only be applied against disease‐transmitting mosquitoes when only sterile male mosquitoes are released, and the blood‐sucking and potentially disease‐transmitting females are eliminated from the production line. For Anopheles ...

  • Contamination by Organochlorine Pesticides from Rivers

    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 pesticides were in the range of 0.94-231.8 ng/L in ...

  • Pesticide removal through wastewater and advanced treatment: full-scale sampling and bench-scale testing

    Dieldrin and DDx removal through wastewater treatment, ozonation, and microfiltration was assessed for a water reuse project for groundwater replenishment in Monterey, California, USA. Full-scale sampling was conducted at the wastewater treatment plant, and physical wastewater treatment processes, ozonation, and microfiltration were tested at the bench scale. Removals observed through ...

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

    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:  Source area maximum dieldrin ...

  • 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 impacted soil remains at many sites. Such was the case ...


  • Cattle egrets as a biosentinels of persistent organic pollutants exposure

    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 ΣDDT, followed by β-HCH, γ-HCH, ...

  • In Situ Chemical Reduction (ISCR) for removal of persistent pesticides; focus on kepone in tropical soils

    The global use of organochlorine pesticides (OCPs) such as Kepone, Lindane, DDT, Dieldrin, Chlordane, and Toxaphene has resulted in long-term soil impacts at many sites. Given the potential risks to human health and the environment, some OCP-impacted sites require treatment. In certain cases, the “dig-and-dump” approach is not practical due to magnitude of the problem, access issues, ...


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

    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 years. Whole fish were analyzed for a number of ...

  • Good intentions may result in bad health

    President Obama’s stimulus investments in home energy efficiency may have the unintended consequence of increasing future medical costs. The stimulus bill contains $1500 tax credits for homeowners who install energy efficient doors, windows, and/or insulation. Studies in both the United States and England have shown that these home upgrades can reduce air infiltration by 50% in older homes, and ...

  • Temporal and Spatial Trends in Chlorinated Hydrocarbon Concentrations of Mink in Canadian Lakes Erie and St. Clair

    Mink (Mustela vison) carcasses were collected from local commercial trappers from fall 1998 to spring 2003 from tributaries and marshes within 4.8km from the shores of Lakes Erie and St. Clair, including the Wheatley Harbour and St. Clair River Areas of Concern (AOCs), as well as from inland sites (8 to 40km from shore). Liver concentrations, on a lipid weight basis, of chlorinated hydrocarbons ...

  • Soil Remediation

    Contaminated sites by hazardous substances are a major environmental concern in Europe e throughout the world. Significant financial and human resources are devoted for the remediation of such sites. Many steps have been taken to restrict or ban from use some contaminants (PCBs, IPA, CLB-derivatives) and reduce discharge of others. However, contaminants can persist for many years in soil and ...


  • Levels of organochlorine pesticides residues in meat

    Abstract: Concentrations of organochlorine pesticides (Lindane, Aldrin, Dieldrin, Endosulfan, DDT and DDE) residues in beef samples from the Kumasi and Buoho abattoirs in Ghana were determined using gas chromatography. Organochlorine residues were found in all the samples. The average concentration of lindane in beef fat samples from Kumasi was 4.03 µg/kg and 1.79 µg/kg in beef fat from Buoho. ...

  • Pesticide Terminator

    Impacted Soil Bioremediation - Environmental Protection magazine (May 2007) As urban centers grow in size, substantial areas of agricultural and industrial land are being converted to residential use. One of the issues frequently encountered when such a change in land use is implemented is the presence of elevated concentrations of chlorinated pesticides and herbicides historically used in ...

  • How treatment of homes for termites decades ago may cause diabetes today

    Obesity has been accepted as a risk factor for diabetes but results of four recently published studies have now revealed that insecticides in fat of patients may be the real risk factor. The initial investigations showed that the expected association between obesity and diabetes/insulin resistance was absent in people who had low levels of organochlorine insecticides in their blood (1, 2). ...

  • The Bioremediation Process

    Bioremediation allows natural processes to clean up harmful chemicals in the environment. Microscopic 'bugs' or microbes that live in soil and groundwater like to eat certain harmful chemicals, such as those found in gasoline and oil spills. When microbes completely digest these chemicals, they change them into water and harmless gases such as carbon dioxide. In order for microbes to clean up ...


  • The In Situ Bioremediation/Groundwater Remediation Process

    In-situ groundwater bioremediation is a technology that encourages growth and reproduction of indigenous microorganisms to enhance biodegradation of organic constituents in the saturated zone. In-situ groundwater bioremediation can effectively degrade organic constituents which are dissolved in groundwater and adsorbed onto the aquifer matrix.
