Surface water samples of two sections were respectively collected from one side to the other side of Honghu Lake, China, in order to detect the concentrations and distribution of HCHs in the region. The concentrations of total HCHs (the sum of α-HCH, β-HCH,γ-HCH and δ-HCH) in surface water of Honghu Lake ranged from 0.94 to 7.04 ng/L. The highest concentration of HCHs in water was near a shipping traffic path. HCHs were derived mainly from agricultural runoff around Honghu Lake and release of the sediments. Among four component compounds of HCHs, γ-HCH was major contributor in the water, which suggested that lindane may have been used recently around Honghu Lake. |
