Pesticide use in Bangladesh is often excessive and unregulated. Despite their worldwide ban, Persistent Organic Pollutants (POPs) and other harmful organochlorine pesticides are widely being used. No studies have been done in Bangladesh on the presence of POPs in water from and around agricultural fields. This study detected POPs such as HCB, O, P`-DDT, DDD, 4, 4`-DDT, α-HCH, β-HCH and δ-HCH in water samples. The samples were analyzed using standard test methods. The tests indicated that at least one of the seven pesticides was in every sample collected. The concentration of analytes ranged from 121.793x10-2 μgL-1 for 4, 4`-DDT to 0.014x10-2 μgL-1 for HCB. 13 of the 15 samples had at least one of the three isomers of DDT in them. δ-HCH was present in all the samples. The presence of POPs in every sample indicates continued use of harmful pesticides in the country.
