惠安南埔湾海水养殖区一次油污染的监测

Monitoring of a oil pollution case in seawater aquaculture area of Nanpu Bay Huian

对福建炼油厂1993年2月12日溢油事故的监测结果表明，惠安县南埔湾的天竺、张俱、仑头一带养殖区域已受到溢油的严重污染。湾内养殖的主要经济贝类活体的油含量大大高于长江口以南沿岸海域同种类的生物样，其中养殖区域的牡蛎、缢蛏、花蛤活体内油含量分别为（238～2270）×10－6（m／m），2840×10－6（m／m），（276～294）×10-6（m／m），平均死亡率高达70％以上，残活生物体含有油污臭味，表层沉积物油含量介于3．5×10－6～5704×10－6之间，超标率为36％。

The oil spill accident caused by Fujian Oil Refinery on Feb. 12. 1 993 was monitored and the results domonstrated that the waters around Tianzhuu-Zhangju-Luntou in Nanpu, Huian county was severely polluted by the splll. The oil content in the cultured living shellfishes was significantly higher than that from the natural species sampled to the south of Changjiang River mouth. The oil content [10 -6 (m/m )] in the living oysler rajor clam and tapes reched 238 ～ 2 270, 2 840 and 276～ 294 respectively. The mean mortality was over 70%, resulting in oil stinking of the animals. The oil content of sediments ranged between (3. 5～5 704) ×10-6(m/m),36% over the stan dard figure.
