  • Pesticide destruction in agrochemical wastewater with DiaCell® - Technology

    Chemicals commonly called pesticides (herbicides, insecticides) are extensively used in farming to increase yields and protect crops. These products are very efficient but they are also very toxic. Pesticides may have ecological effects or be toxic for various terrestrial and aquatic animals and plants. These effects may be due both to the pesticide itself as well as its breakdown products. The ...


  • Bioremediation of PCB & Pesticide Contaminated Soils Utilizing Gene Expression Factors

     Abstract Historically soils contaminated by persistent organic compounds such as pesticides and PCBs were not considered good candidates for bioremediation due to the simple fact that the chemical industry designed these compounds to withstand the destructive effects of natural attenuation through weathering and microbial activity. Although the chemical industry has long appreciated the ...


  • Monitoring the aquatic toxicity of mosquito vector control spray pesticides to freshwater receiving waters

    Pesticides are applied to state and local waterways in California to control insects such as mosquitoes, which are known to serve as a vector for West Nile Virus infection of humans. The California State Water Resources Control Board adopted a National Pollutant Discharge Elimination System General Permit to address the discharge of pesticides to waters of the United States resulting from ...

  • Impact of 1,4-Dioxane from Domestic Effluent on the Agano and Shinano Rivers, Japan

    1,4-Dioxane is a polar and low-biodegradable organic compound. It is used as an industrial solvent or solvent stabilizer that prevents the breakdown of chlorinated solvents during manufacturing processes (Zenker et al. 2003). Industrial solvents are used in decreasing, electronics, metal finishing, fabric cleaning, pharmaceuticals, herbicides and pesticides, anti freeze, paper manufacturing and ...

  • Application of pocis for exposure assessment of munitions constituents during constant and fluctuating exposure

    Potential use of polar organic chemical integrative samplers (POCIS) for exposure assessment of munitions constituents (MC), including 2,4,6‐trinitrotoluene (TNT) and hexahydro‐1,3,5‐trinitro‐1,3,5‐triazine (RDX), and their breakdown products (aminodinitrotoluenes [ADNTs], diaminonitrotoluenes [DANTs], and hexahydro‐1,3,5‐trinitroso‐1,3,5‐triazine [TNX]), was examined. Loss of MC from the ...

  • Co-Metabolic Processes

    Introduction: Co-metabolism is one form of secondary substrate transformation in which enzymes produced for primary substrate oxidation are capable of degrading the secondary substrate fortuitously, even though the secondary substrates do not afford sufficient energy to sustain the microbial population. An emerging application involves the injection of water containing dissolved primary ...

  • Phytoremediation - II

    Introduction: Phytoremediation is a set of processes that uses plants to clean contamination in ground water and surface water. There are several ways plants can be used for the phytoremediation. These mechanisms include enhanced rhizosphere biodegradation, hydraulic control, phyto-degradation and phyto-volatilization. Enhanced Rhizosphere Biodegradation Enhanced ...

  • Landfill Leachate Sources and Treatment Options

    What is leachate? In a lab, it is any liquid that extracts solids as it passes through matter. In a landfill, it is the water that enters the facility in a number of ways, passes through waste material on contact, contains a wide range of constituents, and must be addressed with a proper operations plan. Leachate treatment options and mitigation are one of the greatest costs for landfill ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...
