渤海湾是个半封闭型海湾。周围河流携带的颗粒物质,大部分在湾內沉积,成为湾內沉积物的主要来源。 铁、锰、铝和有机物,对许多微量金属的河口行为有着直接的影响。1981年8月,我们采集了渤海湾及其周围几条河流的表层底质样品(共54份),进行铁、锰、砷和有机物测定;并通过化学沥滤,分离、测定沉积物中水合氧 Bohai Bay is a semi-enclosed bay. Most of the particulate matter carried by the surrounding rivers is deposited within the bay, making it a major source of sediment in the bay. Iron, manganese, aluminum and organic matter have a direct effect on the mouth behavior of many trace metals. In August 1981, we collected surface sediment samples (54 in total) from several rivers in and around the Bohai Bay for ferrous, manganese, arsenic and organics determination and chemical leaching, separation and determination of hydration in sediments oxygen
