Abstract：
Mercury (Hg) contamination in open coastal areas has attracted public concern regarding safe fish consumption and management of the coastal environment, especially in areas of accidental Hg spills on inland coasts. This study investigated the temporal and spatial distribution of Hg in sediments of Youngil Bay and the Hupo Basin, East Sea, Korea; it also discussed the sources and transport of anthropogenic Hg. Hg hot spots were found in the northern Hupo Basin (elevated by 2-3×) and the river mouth area in Youngil Bay (elevated by approximately 70×). The river mouth contamination resulted from the destruction of a dam impounding landfill waste, while the basin contamination was attributed to atmospheric deposition and Hg enrichment associated with increased organic carbon concentrations driven by high biological production in the coastal upwelling area. Spilled Hg was transported to open coastal areas up to 36.6°N.
摘要：
沿海开放地区的汞（Hg）污染引起了公众对安全鱼类消费和沿海环境管理的关注，特别是在内陆海岸意外汞泄漏的地区。这项研究调查了Youngil湾和Hupo盆地沉积物中汞的时空分布，东海,韩国；它还讨论了人为汞的来源和运输。在Hupo盆地北部（升高2-3倍）和Youngil湾的河口地区（升高约70倍）发现了汞热点。河口污染是由于蓄水垃圾的大坝被摧毁造成的，而流域污染归因于大气沉积和汞富集，这与沿海上升流地区高生物产量导致的有机碳浓度增加有关。泄漏的汞被运输到高达36.6°N的沿海开放地区。
