Marked genotoxic damage was developed in even younger pilots with 2 years of work experience caused by their daily occupational exposure to pesticides. Refer to EPAs National Primary Drinking Water Regulations.
The percutaneous absorption has been investigated in rats of a mixture 32 ww of N-methyl-2-pyrrolidinone and 2-pyrrolidinone a combination intended for use as a vehicle in the formulation of an antimycotic drug to enhance skin penetration on dermal application following co-administration of the two 14C-radiolabelled compounds by the dermal and oral routes.
Chlordane bioconcentration factor. Bioconcentration is the specific bioaccumulation process by which the concentration of a chemical in an organism becomes higher than its concentration in the air or water around the organism. Although the process is the same for natural and anthropogenic chemicals the term bioconcentration usually refers to chemicals foreign to the organism. For fish and other aquatic animals.
The fish tissue bioconcentration factor BCF is from the 1980 Ambient Water Quality Criteria document. EPA has issued a Maximum Contaminant Level MCL for this chemical which may be more stringent. Refer to EPAs National Primary Drinking Water Regulations.
This criterion is based on carcinogenicity of 10-6 risk. Alternate risk levels may be obtained. A slope factor and the accompanying weight-of-evidence determination are the toxicity data most commonly used to evaluate potential human carcinogenic risks.
Generally the slope factor is a plausible upper-bound estimate of the probability of a response per unit intake of a chemical over a lifetime. The slope factor is used in risk assessments to estimate an upper-bound lifetime probability. The chemicals targeted by the Stockholm Convention are listed in the annexes of the convention text.
Annex A Elimination Parties must take measures to eliminate the production and use of the chemicals listed under Annex A. Specific exemptions are available in Annex A and apply only to Parties that have registered for them. The indicative list of substances covered by the listing of PFOA.
Endrin is an organochloride with the chemical formula C 12 H 8 Cl 6 O that was first produced in 1950 by Shell and Velsicol Chemical CorporationIt was primarily used as an insecticide as well as a rodenticide and piscicideIt is a colourless odorless solid although commercial samples are often off-white. Endrin was manufactured as an emulsifiable solution known commercially as Endrex. The percutaneous absorption has been investigated in rats of a mixture 32 ww of N-methyl-2-pyrrolidinone and 2-pyrrolidinone a combination intended for use as a vehicle in the formulation of an antimycotic drug to enhance skin penetration on dermal application following co-administration of the two 14C-radiolabelled compounds by the dermal and oral routes.
Dieldrin 15 emulsifiable concentrate and 72 chlordane emulsfiable concentrates. Mixed 13 ratio placed into a liquid injection incinerator with a temperature range of 877-1038 C and residence time of 0153-171 sec with 458-51 excess air produced a destruction efficiency of 9998. M Highest attainable use is the modified aquatic life wildlife or recreation use that is both closest to the uses specified in section 101a2 of the Act and attainable based on the evaluation of the factors in 13110g that precludes attainment of the use and any other information or analyses that were used to evaluate attainability.
There is no required highest attainable use. Pesticide exposure was the main factor for nuclear abnormality results and DNA damage. Marked genotoxic damage was developed in even younger pilots with 2 years of work experience caused by their daily occupational exposure to pesticides.
As in other studies the damages found were not influenced by smoking habits or the consumption of alcoholic beverages. Purchase Encyclopedia of Toxicology - 3rd Edition. Print Book E-Book.
