ANTHROPOGENIC LEAD IN EAST CHINA SEA SEDIMENTS: SOURCE, TRANSPORT PATHWAY AND INPUT HISTORY
 
Since China launched its modernization campaign in the late 1970s, the nation's energy consumption has more than doubled and its GDP more than quadrupled. In the meantime, because of the lack of waste control practices, increases of pollutants released to the environment have paralleled the economic growth. This report will reveal the history of lead pollution recorded in sediment cores. Our data show that the Yangtze River is the main source of sediments and pollutants in the East China Sea (ECS). The increase with time of anthropogenic lead in sediments of the ECS during the past two decades is similar to those in the Southern California Bight during 1930-70. This indicates that the ECS has been contaminated by lead at a rate twice faster than the worst case in the western seaboard of U.S. 3-7 decades ago. As it was in the North America, oil consumption is the major source of anthropogenic lead. To sustain its economic growth, China's oil consumption and hence production of anthropogenic lead are expected to increase in future decades. To halt the trend of lead pollution, regulatory measures such as sewage treatment and the phasing out of leaded gasoline should be mandated urgently.
