目前海洋污染问题已引起人们广泛的重视。探讨这种污染对长期居住在沿海地区的居民,特别是渔民健康的影响,并寻找比较敏感的生物学指标已成为一个迫切的问题。胶州湾是渤黄海污染较重的海湾之一,每年承纳青岛市有害废水1987万吨。使海水、底质和海产品受到了汞、镉、砷、油、有机氯等污染。根据1978～1979年的测定,湾内红岛海区海带的部分样品汞含量超过了国家食品卫生标准(0.3毫克/公斤),对该岛123名渔民发汞的测定,总汞均值为4.80ppm,为邻近农民的10倍。因此,我
At present, the issue of marine pollution has aroused widespread attention. To explore the impact of such pollution on the health of long-term residents living in coastal areas, especially fishermen, and to find more sensitive biological indicators has become an urgent issue. Jiaozhou Bay is one of the gulfs polluted by the Bohai Sea and takes in 19,700 tons of harmful waste water in Qingdao annually. Sea water, sediment and seafood have been mercury, cadmium, arsenic, oil, organic chlorine pollution. According to the determination from 1978 to 1979, the mercury content of some samples of kelp in the Hongdao Bay of the Bay exceeded the national food hygiene standard (0.3 mg / kg). The mercury emission of 123 fishermen on the island was 4.80ppm, which was Nearly 10 times the farmers. so I
