The distribution of dissolved lead in the coastal waters of the East China Sea was investigated seasonally. The average concentrations in surface waters during the spring and autumn were 0.52 nM and 0.27 nM, respectively. In the spring, the concentration of dissolved Pb in the surface waters and bottom waters ranged from 0.13 to 1.86 nM and from 0.15 to 0.94 nM, respectively. For both the surface water and the bottom water, the highest values were observed at the Yangtze River Estuary. Seasonal variability of D-Pb between spring and autumn in the ECS was observed. These results suggested that riverine inputs and atmospheric inputs may be the main sources of lead in this area, while adsorption and co-precipitation on suspended particles at the river estuary and biological process may be the major sinks.
对东中国海近岸海域溶解态铅的分布进行了季节性调查。春季和秋季表层水体中的平均浓度分别为0.52纳摩尔/升和0.27纳摩尔/升。春季，表层水和底层水中溶解态铅的浓度分别在0.13至1.86纳摩尔/升和0.15至0.94纳摩尔/升之间。表层水和底层水在长江口均观测到最高值。观测到东中国海春季和秋季之间溶解态铅的季节变化。这些结果表明，河流输入和大气输入可能是该区域铅的主要来源，而河口悬浮颗粒上的吸附和共沉淀以及生物过程可能是主要汇。
