    摘要 〔目的〕 了解入境船舶载自境外的压舱水中重金属元素污染情况。〔方法〕无菌采集入境船舶载自境外的压舱水样本，送实验室进行包括镉、铬、铅、汞、砷、铜、镍、锌等重金属元素检测。〔结果〕从河北三个港口入境船舶36艘次采集样本36份，进行重金属检测。其中检出铅1艘次，船舶压舱水阳性率为2.78%（1/36）；检出锌36艘次，船舶压舱水阳性率为100.00%（36/36）；检出镍16艘次，船舶压舱水阳性率为44.44%（16/36）；检测铜8艘次，7艘次为阳性，船舶压舱水阳性率为87.50%（7/8）。铬、镉、汞、砷未检出。〔结论〕入境船舶载自境外的压舱水重金属污染非常严重，应引起相关部门的高度重视。

    [Abstract]   Objective  To determine the conditions of the ballast water polluted by heavymetals loaded from abroad in entry ships.  Method  The samples of the ballast water in the entry ships loaded fromabroad were collected in sterile conditions．The heavy metals in thesamples were detected in lab.  Result   A total of36 entry ships' ballast water samples were surveyed. In which，1sample was tested positive with Lead element and the ships' ballastwater positive rate was 2.78%(1/36); 36 samples were testedpositive with Zinc element，and the ships' ballast water positiverate was 100.00%(36/36); 16 samples were tested positive withNickel element，and  the ships' ballast water positive rate was44.44%(16/36); 7 of 8 samples were tested positive with Copperelement and the ships' ballast water positive rate was 87.50%(7/8).Other heavy metals were tested negative. Conclusion   Itis important to pay attention to heavy metal pullution in ballastwater of entry ships.
