CHANGES IN SOIL CONTAMINATION BY SELECTED HERBICIDES USED IN PROTECTION OF CEREALS

Mariusz Kucharski, Krzysztof Domaradzki

Abstract


The aim of the studies was to evaluate the herbicidal contaminations in soil. Monitoring tests were carried out in two periods: 2002–2008 and 2010–2013, on cereal plantations located in south-western Poland. The samples of soil were collected at harvest time. The determination of 2,4-D, MCPA, diflufenican, dicamba, chlortoluron, fluroxypyr, isoproturon, clopyralid residues were conducted using the chromatography GC/ECD and HPLC/UV. Comparing the research results from both periods, a decrease of several percent in the number of the samples with residues was observed. In the years 2010–2013, the average residues of herbicide determined in 27% of samples ranged from 0.0012 to 0.0052 mg kg-1.1
