Jiangsu random sample no problem

Scenedesmus rice exceed 10% of the existence of cadmium?

South nongda professor response: don't panic!

Only 10% of random sample of cadmium exceeds bid, and jiangsu exists selective examination found no problem

About 10% of cadmium exceeds bid scenedesmus rice by cadmium pollution and could cause bone pain disease. Yesterday was a media reported on the content, causing the citizens of widespread concern. Reporter interviewed yesterday in this poll of nanjing agricultural university agricultural resources and ecological environment institute professor PanGenXing, he answered and said, "not all on the market of rice is such, jiangsu samples will do not have what problem, can only say that we random sample of existing cadmium exceeds 10%, everybody don't panic".

Sampling 10% of cadmium exceeds bid exist

In 2007, PanGen XingHe his research team, in the whole nation in six areas (east, northeast, south and central China, southwest, north China) at or above the county level shall purchase market random rice sample more than 100, and came back they specifically for the tests, random sample testing results show that the existing cadmium exceeds 10%. April 2008, PanGenXing and led his team from jiangxi, hunan, guangdong province farmer market random sampling 63 copies, experimental results confirm samples for 60% of rice cadmium content exceeds national limits.

Similarly, 2002, the agriculture department rice and products quality supervision and inspection and test center was the national markets for safety 45.5% and rice. The results showed that rice in the most serious heavy metal exceeds bid is lead, cadmium 28.4%, followed by 12%, 12% 10.3%.

Cadmium exceeds meters may cause bone pain disease

Rice cadmium exceeds bid will have what harm? PanGenXing said, cadmium is a kind of heavy metal, can restrain the absorption of zinc and selenium, hind two kinds of is promoting calcium absorption of trace elements. Body cadmium exceeds easy troubil hypertension, emphysema, osteoporosis wait for disease. "Cadmium enter human body, after many years can cause bone pain wait for disease, serious will cause terrible bone pain disease." PanGenXing said. In addition, cadmium instead of calcium, zinc and other elements, it is apt to cause the body function disorder, affect the body metabolization.

It is reported, the world health organization has announced the century on 8 big nuisance events, including Japan "cadmium meters poisoning" cause bone pain disease events.

[remind]

What causes rice cadmium pollution that exceeds bid suffer? PanGenXing introduced that the land contamination is one big reason, and the southern acidic soil super hybrid rice planting than conventional rice varieties easily absorb cadmium.

China's annual output of rice nearly 2 million tons, 10% namely 2000 tons. These figures to explain the seriousness of this problem. PanGenXing their research shows that Chinese rice heavy metal pollution mainly with the southern rice, especially in hunan and jiangxi provinces oriented.

It is reported, jiangsu total last year grow rice 33.5 million mu, the province from the south to the north have rice fields. So whether also exist in jiangsu rice cadmium exceeds the problem? "From a random look, jiangsu sample do not have what problem." PanGenXing explained, jiangsu most of the lands are not acidic, therefore will avoid the problem.

[melancholy]

Urbanites don't worry poisoning

Have fears ate cadmium exceeds the rice, it is apt to cause the cadmium poisoning. To this, PanGenXing said, cadmium poisoning is a long-term process, the accumulation of rice edible has now urbanite reach the amount of poisoning. "In fact, city need not worry, because everybody eat is" party ". PanGenXing tells a reporter, like nanjing on the rice may come from all over the country, ordinary people in different supermarket buy different brands of rice. If long-term buy a brand of rice, then the quality should also have security, "brand rice generally has its own base to land pollution monitoring is stricter."

He said actually tens of millions of pollution area rice farmers is the biggest victims. Because rice is the staple food they eat three meals a day, some farmers with knowledge of the pollution, but trapped in selling unclean meters to buy net meters between the price of loss, and forced to eat pollution rice. More farmers do not know oneself eating rice is toxic heavy metals, they even don't know what it is.
