- Abstract
The rainwater samples collected from the Lucknow city (India) were analyzed for selected organochlorine pesticides (OCPs) and polycyclic aromatic hydrocarbons (PAHs). HCH-isomers contributed most to the ΣOCPs with the highest levels of β-HCH isomer. The OCPs, which are currently banned in the country, were also observed. The residue levels of ΣOCPs in rainwater samples ranged between BDL and 447.17 ng L−1. Endrin, β-endosulfan, heptachlor epoxide B and methoxychlor could not be detected in any of the sample. The levels of ΣPAHs in rainwater samples ranged between 19.32 and 11,112.09 ng L−1 and the most abundant hydrocarbon was acenaphthylene. Further, the lower molecular weight PAHs dominated over the high molecular weight compounds.
