Abstract

Soil contamination with pesticide and biogenie compounds is a serious problem. The following compounds are detected most often and in largest quantities: lindan, DDT (not used for many years now), Simazine, Atrazine, Chlorfenvinphos and Fenitrothion. The presence of pesticides in surficial waters in the Żuławy Wiślane region has been described many times. Additionally, my own research con finned the presence of pesticides in superficial waters in Podlasie. This paper presents the results of the concentrations determination ofphenoxyacetic herbicides , biogenics and other pollutants in the Białka river. The samples were collected over a period of one year, from April 2000 to March 200 I. The analysis was carried out by reverse phase HPLC and TLC chromatography and colorimetric and spectrophotometric methods by HACH apparatus.

Abstract

The paper presents the results on the studies on determination of concentrations or four phenoxyacetic herbicides, four triazine herbicides. seven insecticides and other pollutants in the Supraśl catchment. The samples were collected over a period or two years. from May 2003 to April 2005. This work will be a precious source or information about the occurrence of agropollutants in the surface water. The residues of herbicides active ingredients were determined using chromatography methods - GC with ECD and NP detection. The maximum residues or herbicide in surface water were detected in spring and autumn - up to 120 ug/dm: for phenoxyacetic acid (2,4-D, MCPA, MCPP). The most important fact noted during the research is that in surface water used for drinking significant amounts of crop protection substances were detected, which, in the light of the new law concerning the quality of drinking water. must undoubtedly be removed in the treatment processes.
