ZHUZHOU, Hunan Province: The levels of cadmium in a small section of the
Xiangjiang River in this Central China Province are still above safety levels
after a spill last week, a senior provincial official said yesterday.
The levels were "one or two times" higher than the national standard in the
Wangcheng section of the river in a suburban county of provincial capital
Changsha, Jiang Yimin, provincial environmental head, told China Daily.
Cadmium, a chemical that can cause neurological disorders and cancer, seeped
into the Xiangjiang River during a silt-cleaning project on January 4.
Jiang said "drinking water for households is safe due to timely emergency
The spill happened in Zhuzhou, an industrial hub, and polluted a stretch of
100 kilometres of the river, a tributary of the Yangtze.
"We need to keep on alert in case there is new pollution and the cadmium
level rises," said Jiang.
The cadmium content in the river peaked at 80 times the safety level some
days ago, according to Jiang.
Local authorities are neutralizing the spill with various chemicals and
diluting it by releasing water from upstream reservoirs.
The government has ordered all chemical factories along the river to suspend
Yellow River slick
In another development, a diesel oil pollution slick in the Yellow River
reached Jinan, capital of East China's Shandong Province, yesterday.
Experts estimate that at the current speed, it would flow into the Bohai Sea
The oil leakage occurred on Thursday at the No 2 Power Plant of Gongyi, a
city in Central China's Henan Province.
The neighbouring Shandong Province activated its emergency plan last
Saturday, shutting down 63 water intake points along the Yellow River.
The suspension will not affect urban water supplies as the river water is
mainly used for agriculture, said an official of the provincial environmental
"The suspension could last one week," said Zhang Kai, director of the bureau.
To speed up the dilution of the oil slick, the Xiaolangdi Reservoir on the
Yellow River has doubled its flow to 600 cubic metres per second.
