摘要:
研究广西英罗港红树林区沉积物和大型底栖动物中汞含量的分布规律。结果表明英罗港潮沟沉积物汞平均含量大于林内;部分沉积物受到汞污染。在动物类别水平上,各滩的潮沟样地动物中的汞含量均值均大于相应林内样地动物。在所有动物水平上,潮沟动物汞平均含量高于林内。按动物食性划分,沉积物食性动物汞平均含量最高。按生活型划分,底内生活型动物汞平均含量最高。在生活型和食性的8种组合中,以沉积物为食、以底内型生活的种类平均汞含量最高。动物汞含量超标率为14.29%。

Abstract:
The contents of the mercury in the mangrove sediments and macrobenthos were monitoried in Yingluo Bay, Guangxi in 1994. The results showed that the means mercury contents of sediments in the creek were higher than that under forest. Some of the sediments in Yingluo Bay had been polluted by mecury. At the level of species categories, the means mercury contents of macrobenthos at each sample point were higher in the creek than that under forest. At the level of all species, the means mercury content of macrobenthos in creek was higher than that under forest. Based on their food preference, the soilphagous species had the greatest means mercury contents. And the means mercury contents of infaunal species was higher than that of the other inhabits types. Among 8 combinaton of inhabits and food preference types, the means mercury content of the species with soilphagous food preference and infaunal inhabits type had the greatest value. The over standard rate of the mercury contents in macrobenthos was 14.29%.
Key words:  mangrove  sediment  macrobenthos  mercury contents
