Pollution

A total of 145,000 square kilometers of shallow waters along China's vast coast failed to meet national quality standards for clean oceanic water, of which 29,000 square kilometers of seawater were seriously polluted. These severely polluted water areas included East Liaoning, Bohai and Hangzhou bays, and the estuaries of Yellow, Yangtze and Zhujiang rivers, as well as inshore areas of major coastal cities. Content of major pollutants, such as inorganic nitrogen and phosphate, remains high in contaminated seawater. During the past 50 years, the inshore ecosystem had seen 50 percent of coastal wetlands disappear in excessive reclamation and 80 percent of coral reefs and mangroves destroyed.
