A method for the determination of 2,4-D and its toxic metabolites in the biosphere
A method for the quantitative determination of residues of the herbicide
2,4-dichlorophenoxyacetic acid (2,4-D) and its toxic oxyderivatives has been
developed. 14C-2,4-D, thin layer chromatography and hydrolysis of 2,4-D conjugates
have been employed to optimize the method.The method is characterized by high
specificity and sensitivity; the lower detection limit is 0.02 mg/kg of fresh
sample.
Key words: conjugates; herbicide; hydrolysis; 2,4-dichlorophenoxyacetic
acid
