摘要: 对采自虎门潮汐水道狮子洋4个采样点表层水样中的多环芳烃、有机氯农药进行了定量分析。洪、枯水期水体中多环芳烃总量(颗粒相和溶解相) 分别是786~964 ng/L、11 360~19 603 ng/L;有机氯农药总量分别是9.68~26.29 ng/L、41.65~96.23 ng/L。根据4个采样点洪、枯水期有机污染物浓度的平均值估算多环芳烃、有机氯农药的年均入海通量。初步估算结果显示:多环芳烃的总入海通量(溶解相和颗粒相)为438.4×103 kg/a,其中颗粒相是52.5×103 kg/a;16种优控多环芳烃的入海通量为247.9×103 kg/a。有机氯农药的总入海通量是2.6×103 kg/a,其中六六六的入海通量为1.1×103 kg/a,滴滴涕类的入海通量为0.3×103 kg/a,其它有机氯农药的入海通量为1.2×103 kg/a。

Abstract: Polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides (OCPs) in surface water samples from Humen tidal channel were identified and measured quantitatively, based on USEPA 8000 series methods and under quality assurance and quality control (QA/QC). The total (particulate plus dissolved phase) concentrations of PAHs in surface water from Humen tidal channel in both high flow season and low flow season were 786-964 ng/L and 11 360-19 603 ng/L respectively, and the total concentrations of OCPs in both seasons were 9.68-26.29 ng/L and 41.65-96.23 ng/L respectively. The average of concentrations of the 4 water samples from Humen tidal channel both in high flow season and in low flow season was used to estimate the annual fluxes of PAHs and OCPs. The results are as follows: the total PAHs (particulate and dissolved phase) flux from the Pearl River Artery to the Lingdingyang Estuary was 438.4?103 kg/a,and the flux of the particulate phase PAHs was 52.5?103 kg/a; the flux of 16 PAHs was estimated to be 247.9?103 kg/a. The total OCPs flux was 2.6?103 kg/a,of which the HCHs, DDTs and other OCPs were 1.1?103 kg/a,0.3?103 kg/aand 1.2?103 kg/a respectively.
