Despite improvement in some areas, pollution in China's coastal
areas remain "severe", according to a report released Tuesday by
the State Oceanic Administration (SOA).
About 145,000 square km of coastal area was polluted in 2007,
down 4,000 square km from the previous year, the report on China's
oceanic environment said.
The Bohai Bay
Among the most heavily polluted coastal areas are Liaodong Bay,
Bohai Bay, Yellow River Estuary, Laizhou Bay, Yangtze River
Estuary, Hangzhou Bay and Zhujiang River Estuary, the report
The northern Bohai Sea, the worst polluted sea area in the
country, still suffered from heavy pollution. The polluted area
measured 24,000 square km, or 31 percent of the total Bohai area,
an increase of 4,000 square km from the 2006 figure.
"The deterioration trend of China's coastal area eco-system has
not been eased," said Li Xiaoming, the SOA's Department of Ocean
Environment Protection director.
About 78 percent of the 18 regions under ecological monitoring
were in a sub-state of ecological health or unhealthy. They
featured eutrophication, a decrease in oceanic resources and an
alienation of biotic community structure, according to Li.
China had 82 cases of red tide in 2007, contaminating 11,610
square km of sea area. Pollutants were blamed for the cause of the
red tides in which large amounts of algae kill sea creatures.
"Oceanic authorities at all levels must strengthen supervision
on terrestrial pollution sources near sea areas," Li said, noting
87.6 percent of the 573 monitoring points of sediment in the sea
areas discharged excessive amount of chemicals.
