3.10.11.Silnoe pollution of the Pearl River (Pearl River), metals and organic compounds has led to the accumulation of these substances in the bodies of river and marine life, the eating of which has become dangerous to human health.
For example, in the oysters from Guangdong Province copper in 740 times higher than normal.
According to the publication "Yanchen Vanbao", according to the recently promulgated Maritime Bulletin of Guangdong Province in 2010, 40% of the pollution discharged into the sea of industrial waste overfished, 16% of the sea water is polluted.
It says that in 2010, eight of the rivers flowing into the sea province brought in its waters 1.08 million tonnes of petroleum hydrocarbons, arsenic, heavy metals and other industrial pollution. 70% of the pollution in the sea brings the Pearl River.
Pollutants not only make the water unfit for consumption, but also actively accumulate in organisms, river and sea creatures.
For example, in the kidney, liver, gonads and gills kolyuchegolovogo slabs of chromium and lead, respectively, higher than normal at 24 and 48 times. In the body of the other game fish — homaloptera (fish-lizard), the lead content 53 times higher than normal. And oysters copper and cadmium above normal, respectively 740 and 90 times, the article says.
The greatest amount of copper, zinc and cadmium contained in the body of water to the inhabitants of fishing waters of coastal cities Shenzhen, Zhuhai and Macao.
To minimize the risk of poisoning, experts advise during eating gastropods and bivalves leave only muscle.
Last year, Greenpeace published a report according to which the body fish living in China's longest Yangtze River, contains chemicals that are dangerous for human health. Among the most dangerous — is alkylphenol (NP) and nonylphenol, used in detergent and textile industries, as well as the most resistant to degradation perfluorinated sulfonate (PFOS), which is added to the plastic coating and grease. In the body of some fish from the river were also found mercury, lead, cadmium and other heavy metals.
In 2007, according to Greenpeace, in the Yangtze River were dropped more than 27 billion tons of industrial waste at least 10,000 chemical factories located on its banks.
