The coastal regions of inland seas are particularly vulnerable to Hg pollution. An important carrier of toxic Hg in the marine environment is suspended matter originating from multiple sources. The present study was conducted in the Gulf of Gdańsk and its adjoining land in the years 2011-2013. The results indicated that the Hg (Hg bound with suspended particulate matter) concentrations varied horizontally and vertically and were dependent on the water dynamics and the composition of organic matter. Conditions favourable for the accumulation of matter and adsorption of reactive gaseous mercury led to increasing Hg levels, which are especially hazardous in the case of semi-enclosed areas such as estuaries. These conditions also increase the Hg loads into the trophic chain through suspension feeders. Moreover, the Hg concentration was significantly affected by seasonal phenomena (mainly coastal erosion) and the quantity and quality of primary production (phytoplankton blooms, mainly Mesodinium rubrum).
内陆海的沿海地区特别容易受到汞污染。海洋环境中有毒汞的一个重要载体是源自多种来源的悬浮物。本研究于 2011 年至 2013 年在格但斯克湾及其毗邻陆地进行。结果表明，Hg（与悬浮颗粒物结合的 Hg）浓度在水平和垂直方向上发生变化，且取决于水动力和有机物的组成。有利于物质积累和反应性气态汞吸附的条件导致 Hg 浓度增加，在半封闭区域（如河口），这种情况尤其危险。这些条件还通过悬浮食者将 Hg 负荷带入食物链。此外，Hg 浓度还受到季节性现象（主要是海岸侵蚀）和初级生产力的数量和质量（浮游植物大量繁殖，主要是 Mesodinium rubrum）的显著影响。
