HCHs were detected in the soil of analytic area in the suburbs of Beijing. The concentrations of HCHs in the samples are σ-HCH＞β-HCH＞γ-HCH＞α-HCH and the γ-HCH in all the samples is not the main component of residues, suggesting that no new HCHs have entered soil of the studied area. Compared with the commercial HCHs, the contents of HCHs isomers have changed considerably, the content of α-HCH and γ-HCH have decreased while β-HCH and σ-HCH have increased. The degeneration ratios of isomers are α-HCH＞γ-HCH＞σ-HCH＞β-HCH. Although there are no new HCHs that can pollute this area, the risk remains existent.
