The influence of MCPA on soil ecotoxicity and the presence of genes involved in its biodegradation

摘要

The aim of this study was to evaluate the changes in ecotoxicity of agricultural soil under the influence of Agritox 500SL, an herbicide from the phenoxyacid group, containing MCPA (2-methyl-4-chlorophenoxyacetic acid), applied every 3 weeks for 3 months. Biodegradation potential in control and weathered soil was confirmed by the analysis of the functional gene tfdA using PCR technique. Properties of the soil were assessed by the analysis of granulometric composition, pH, the content of macroelements and heavy metals. The soil ecotoxicity was measured using biotests Phytotoxkit (R) and Aficrotox (R).
