News of February 15 of www.eastday.com: According to " Moring Post ", rice Chinese staple food, one correlated to it news initiate people's concern recently: The sample investigation reveals, commercial rice sample about 10% of six areas of the whole country cadmium including East China exceeds standard. Cadmium is a kind of heavy metal, it causes danger to the skeleton, kidney of the human body to accumulate for a long time, this makes numerous consumers paying close attention to food security worried. But the expert says, the commercial rice in Shanghai mainly comes from the Northeast, Jiangsu and other places when being interviewed by morning paper reporter, the activity is relatively low in cadmium is in the neutral soil of these areas. And the rice in regular channels such as the convenience store of grain and oil, supermarket,etc., through inspecting by random samples ring upon ring, the qualification rate is relatively high, so citizens needn't be too anxious. It is most serious to produce rice cadmium and exceed standard Hunan and Jiangxi " 10% commercial rice from side to side cadmium exceeds standard " ,Investigation result this come from Nanjing agricultural the intersection of university and agricultural resource and ecological Environmental Research Institute Pan stick revitalize professor and the intersection of research and group of him, study in one that 2007 go on. Researchers are in six areas of the whole country ' East China, the Northeast, Central China, southwest, South China and North China) The market above county level purchases 91 samples of rice at random. The result reveals, about 10% of samples cadmium exceeds standard. Among them, Chinese rice heavy metal pollution takes southern polished long-grained nonglutinous rice as the core, it is strong with provinces such as Hunan, Jiangxi,etc. particularly. This research results were published on magazine of " security and environment " later. Cadmium one silvery white glossy heavy metal, grow with zinc ore, the intersection of lead and zinc ore, the intersection of copper and the intersection of lead and zinc ore,etc. mainly. Studies have suggested, cadmium is accumulated, will not disappear in liver, kidney department naturally mainly, through several years being even chronic after accumulating in decades, the human body will present prominent cadium poisoning symptom. Cadmium make whom people are poison route to damage renal function, cause human skeleton grow supersession obstruct usually most, thus initiate various pathological changes of the skeleton. The sixties of last century bone-ache that Japanese Toyama county magic Sichuan basin appeared, relate to pollution of cadmium, influence crowds to reach several hundred people. Pan GenXing said yesterday, rice of southern area such as Hunan of our country, Jiangxi presented cadmium to exceed standard when being interviewed by morning paper reporter, because soil, local the intersection of mine and waste water pollution, some to influenced by sewage discharge of local chemical plant mainly. Meanwhile, the pollution of cadmium has significant irreversibility, once soil is polluted, even if passed for many years, the impact on crops may be extended for a very long time. "The romaine lettuce absorbs the most terrible crop of cadmium, and the rice absorbs the strongest cereal crops to cadmium, second only to the romaine lettuce. " Pan GenXing says: "The romaine lettuces generally all grow in the large canopy, by contrast, the rice growing in the field is easier to be polluted by the heavy metal. " In addition, the unique eating habit causes the heavy metal of rice to pollute and stress in China. Shanghai rice is mainly produced in the Northeast and Jiangsu, the qualification rate is relatively high Rice cadmium exceeds standard the question makes many consumers worried. As to this, Pan GenXing says: "In fact not so terrific. " He explains, 10% cadmium exceeds standard, does not mean 10% rice exceeds standard on the market in the whole country in 91 rice samples. And cadium poisoning is a chronic course that accumulates, though there may be market of some pollution rice flow direction, but what consumers ate is " One hundred families meal " . By contrast, the area polluted in those soil, peasants eat and produce the rice by oneself for a long time, the health problem that they face should cause the attention even more. To the market of Shanghai, general secretary of employer's organization Zhao ZhiWei tells reporters the grain and oil of market, the local commercial rice mainly comes from the Northeast, Jiangsu and other places. Pan GenXing says even, the rice is absorbed to cadmium there are relations with the sour alkalinity of soil very much. Cadmium has activity in the acid soil of southern areas such as Hunan, Jiangxi,etc. even more, and the Northeast, Jiangsu and other places are the neutral soil, have little trouble. The rice is before entering convenience store of regular grain and oil, supermarket, sales field, suppliers must offer the certificate of quality of place of production. In order to guarantee rice quality, some trade companies will also send some products to the relevant organization and examine. The national administrative service division will survey sample to the commercial rice too. "Thus the rice which citizens bought from regular channel, quality is still guaranteed. " Zhao ZhiWei says: "The commercial rice qualification rate in Shanghai is relatively high, have not heard yet that the situation that the heavy metal exceeds standard appear. " The reporter sees on Shanghai Administration of Auality and Technical Supervision website, " spot check the announcement " It was last March to spot check the special supervision of quality to rice of this city the last time when China announced. Spot check 24 kinds of products altogether, test project includes heavy metal such as lead, cadmium, mercury, inorganic arsenic, 666, DDT, yellow aspergillus toxin B1,etc.. It is 91.7% to spot check the qualification rate finally, only 2 kinds of rice were differentiated because small garrulous rice and index of total amount of garrulous rice exceeded standard not up to standard. The food which eats more zinc calcium with high content can be reduced cadmium is absorbed though cadmium pollution has significant irreversibility, once soil pollute easy to remove, Pan stick revitalize, show citizen can reduce to to absorb cadmium by balanced diet. He introduces, cadmium, zinc, calcium have function inhibited each other. Eat some more food of zinc, calcium such as aquatic products, beans products, melon seed, meat, egg with higher content, can reduce human body's absorption of cadmium effectively. Zhao ZhiWei is in term of selecting the rice of high quality " Give an idea " ,Advise consumers to try hard to get to regular convenience store of grain and oil, supermarket, sales field, buy the rice of the big brand. Don't buy to a grain dealer and push the having products without licences that the tricycle is peddled. In addition, the relevant expert proposes, the diet includes eating the rice, try all kinds of varieties more, try not to stare at one to eat.
