Abstract: This study was undertaken to investigate the extent of contamination
from pesticide residues in pond water samples of Bangladesh. Twenty water
samples collected from different locations of Bangladesh were analyzed for the
presence of organochlorine (OCs) and carbamate pesticide residues. Packed
column Gas Chromatographic (Electron Capture Detector Mode) and High
Performance Liquid Chromatography (HPLC) technique were used to determine the
concentration levels of those pesticide residues. The results indicate some
water samples contaminated by organochlorine and carbamate pesticide (carbaryl
and carofuran). The concentration of organochlorine pesticide, DDE and
heptachlor in water sample no. 1 were 0, 0.014 and 0.048 ppm, respectively. The
concentration of organochlorine pesticide, DDE, DDD and DDT in water sample no.
3 were 0, 0.014, 0.052 and 0.316 ppm, respectively. The DDT, DDE, DDD and
heptachlor were found within the WHO guideline value of water quality (2
μgL^{-1} and 0.03 μgL^{-1}). The
concentration of carbaryl in water samples nos. 4, 8 and 10 were 0.609, 0.168
and 0.146 ppm, respectively. The residue level of carofuran pesticide was found
to be in range of 0.398-2.208 ppm. The highest concentration for carbofuran was
2.208 ppm in water sample no. 9, while the lowest concentration was 0.398 ppm
in water sample no. 19. The concentration of carbofuran was also found within
the acceptable ranges according to the WHO guideline value of water quality.
