| 摘 要： | 于1983—1985年采集黄河口及邻海沉积物、海水及悬浮颗粒物样品,测定了底质总汞、海水总汞、溶解总汞、无机汞及悬浮颗粒物总汞。所测定的各种汞的形态均列于世界河口区最低的浓度水平。枯水期无机汞和海水总汞分布相对均匀。丰水期溶解总汞分布均匀,而无机汞、颗粒汞和海水总汞都显示出与盐度、颗粒物含量相似的梯度分布。显示了黄河迳流及所携带大量悬浮颗粒物的重要影响。黄河水的无机特征和海水相对高的有机物含量,使无机汞入海后部分转变成有机汞,同时海水与河水的颗粒汞出现明显差别。底质汞与中值粒径线性相关,颗粒汞与颗粒物含量双曲线相关。近河口区盐度、颗粒物含量及颗粒汞含量有明显分层现象。

| Abstract: | All species of mercury measured in the sediments and water in the area of the Huanghc Estuary and adjacent sea lie on the list of lowest levels in the world estuaries. The distributions more or less homogeneous in the dry season and gradient in the flood season show the main role of the Huanghe runoff with heavy load of silt. The transformation of inorganic mercury into organic species during the mixing between fresh and saline waters, rectilineal correlation of sediment mercury with their median diameter, and the stratification of mercury species near the cstuary were observed. |
