泉州湾红树林湿地沉积物中汞分布及形态特征
Mercury distribution and speciation in the sediments of mangrove wetland in Quanzhou Bay
摘要
Abstract
Surface sediments were sampled from the mangrove wetland in Quanzhou Bay to study the distribution, speciation, and bio-availability of mercury in the sediments. The total mercury content in the sediments ranged in 0. 03-0. 22 mg · kg-1, which met the first class standard of Marine Sediment Quality ( GB 18668-2002) , with the exception of that at site 14. The average proportion of different speciation mercury to total mercury in the sediments presented a sequence of oxidizable ( 84. 0% ) > residual ( 14. 0% ) > reducible ( 1. 8% ) > weak acid soluble ( 0. 2% ) . The relatively high bio-availability of mercury in the sediments indicated certain potential hazard to the mangrove ecosystem.关键词
