Abstract
Concentration Level of pesticides were assessed in the sediment of deep
and shallow lakes from Ajiwa Dam, Batagarawa local Government, Katsina State to
evaluate the different levels of pesticides in the sediment of lacustrine
environments. The catchment areas of the studied environments is characterized
by several agricultural activities and human occupations. Sediment samples were
collected during the dry and the rainy periods and total pesticides analyzed in
gas chromatography coupled to mass spectrometry (GC-MS). The
results showed no seasonal difference in the concentration of pesticides in the
sediment of the deep and shallow lakes, indicating a high consistency in the
presence of the contaminants. Levels varied from 0.0 to 11.4 mg/kg in deep
lakes and 0.0 to 8.4 mg/kg in shallow lakes. In deep lakes similar
concentrations of pesticides was observed at Station 18 Lake and Station 20
Lake, while at Station 19 Lake it was detected a higher level of contamination.
In the sediments of the Station 24 shallow lake highest values of pesticides
were detected in relation to Station 23 and Station 23 shallow lakes.
Importantly, already banned pesticides and organic contaminants were also
detected, thus raising concerns. More studies needs to be done in these lacustrine
environments, since they are used for recreational and water supply purposes.
