| 英文摘要 | It was short of research on the organochlorine pesticides (ocps) residues in the soils of hong kong. sixty-six representative soil samples were collected from the 46 sites covering five types of land uses in hong kong. hexachlorohexanes (hch) and 7 stockholm convention ocps were analyzed by gas chromatograph (gc) equipped with a nickel 63 electronic capture detector (mu ecd). the results presented that hch and 5 stockholm convention pesticides were detected in hong kong soils although the detectable ratio varies to a great extent. the concentration sequence of the five detectable ocps was hch > dichlorodiphenyltrichloroethane (ddt) > hexachlorobenzene (hcb) approximate to endrin > alpha-endosulfan. among the ocps and their homologues or isomers, beta-hch and p,p'-dde were the two predominant substances according to the concentrations and detectable ratios, concentrations of which in soils were averagely 6.12 mu g kg(-1) and 0.41 mu g kg(-1) respectively. soil horizon samples of 0-10 cm, 10-30 cm and > 30 cm depth were selected from nine soil profiles to demonstrate the depth distributions of ddt and hch in soil profiles. concentrations of hch tended to increase gradually from the topsoil to bottom layer while the lowest concentration of ddt is usually found in the subsoil (10-30 cm) in most sampling sites. in addition, close correlations of ph(kcl) and total organic carbon (toc) with hch indicated an effect on the residues of hch caused by these two soils properties, but such relationships were not found with ddt or other ocps.
