Chronic toxicity of 2-methyl-4-chlorophenoxyacetic acid (MCPA) in mice.
One of the phenoxy herbicides, 2-methyl-4-chlorophenoxyacetic acid (MCPA) was soaked with pellet dissolved by corn oil and given to ICR male mice for 18 months at levels of 40, 200, 1,000 and 5,000 ppm (about 3.9, 19.0, 95.6 and 566.4 mg/kg/day, respectively). The animals were then placed on a control diet for 12 months. Treatment with 5,000 ppm of MCPA resulted in a significantly decreased sur...
متن کاملToxicity and distribution of 2-methyl-4-chlorophenoxyacetic acid (MCPA) in developing chick embryos.
The toxicity of the herbicide Erbitox E30, a commercial formulation of 2-methyl-4-chlorophenoxyacetic acid (MCPA) containing 28% MCPA as sodium-potassium salt and 72% of unknown ingredients, was tested on chick embryos. Sterile aqueous solutions of MCPA were injected into the air chamber at doses of 0, 1.5, 3.0, 6.0, 9.0, or 10.5 mg/egg on day 0 or on day 4 of incubation. The mortality rate for...
متن کاملEvaluation of Liver Toxicity of 2-Methyl-3-Hydroxypyridin-4-one in Iron Overloaded Rats
Hydroxypyridinone iron chelators are currently the main candidates for development of orally active iron chelating alternatives to desferrioxamine (DFO). In the present study, the relative efficacy and liver toxicity of a bidentate chelator, 2-methyl-3-hydroxypyridin-4-one (MHPO), was studied in iron overloaded rats and compared with those of DFO. For iron overloading, rats received i.p. ...
متن کاملA fatal intoxication from ingestion of 2-methyl-4-chlorophenoxyacetic acid (MCPA).
We report a fatal intoxication case by the ingestion of an herbicide, 2-methyl-4-chlorophenoxyacetic acid (MCPA). A 23-year-old male was found dead in his car. The forensic autopsy revealed no remarkable morphological changes. However, in a toxicological screening test, MCPA was qualitatively detected from the extracts of stomach contents. Then MCPA in the extract of each body fluid and organ t...
