Cadmium contaminated soil is penetrated through the rice; sample survey of scholars in China and more rice on the market of cadmium exceeded about 10%; in a variety of heavy metal pollution in China before the rice a few undefended
from a mottled paint the table, 84-year-old Li Xiang, pulled less than half bags of rice. Color white, slightly translucent sense of full particles, the naked eye can not see the rice would be any different.
However, after testing, the rice component of cadmium poisoning. The rice will be referred to the locals as
cadmium, a heavy metal, chemical, periodic table in the No. 48 ranking. In nature, it exists as a mineral compound in the human body great harm.
Li Xiang old suspect was a strange disease with the rice on. Old body still in good health, but has more than 20 years could not walk properly. As long as the path does not exceed 100 meters, feet and lower legs will be aching like hell.
doctor could not definitive diagnosis, the elderly altogether their own name - soft-foot disease. He told the reporter, in his life, Yangshuo County, Guangxi Xing Town of thinking of the village, a dozen other elderly people have similar symptoms.
retired in 1982, back to the village from the counting, Li Xiang has been eating rice production for 28 years the village. Confirmed by many scholars, research papers, the village early in the last century cultivated the soil 60 years ago had been contaminated by cadmium; Accordingly, the cadmium content in rice production is also seriously overweight.
medical literature have shown that cadmium into the body, can cause pain after years of embolism, serious cause terrible The so-called Cd resulted in the serious pollution of the mining fields, farmers long-term consumption of contaminated food such as rice on the soil, causing cadmium poisoning, the patient had needle-like bone pain, mouth always shout The symptoms of this disease Xiang Li said the elderly is very similar to the soft foot disease. Directed a number of scholars, many villagers think the village has a suspected
similar cases is not only widely Xisi in the village. In fact, many places have such serious urinary cadmium exceeded population and the corresponding symptoms.
especially worth mentioning is that, regardless of the sampling in recent years, the agricultural sector, or academic studies show that about 10% of the rice in China there is the issue of cadmium exceeded. Global rice consumption for most countries, this is undoubtedly a heavy reality.
in cadmium, the rice, there are also other heavy metals exceeding the issue. Geochemistry, Chinese Academy of Sciences published by the researchers, said that the Chinese inland residents of the main channel of methylmercury intake is rice, not fish. As we all know, one of methylmercury pollution disease is well-known Minamata disease pathogenic culprit.
a complete chain of food contamination has been going on for years. Everywhere during the rapid industrialization of China's mining and other acts, so that the original form of the compounds of cadmium, arsenic, mercury and other harmful heavy metals released into the natural world. These harmful heavy metals through water and air pollution, a large portion of China's land, and thus contaminated the rice, and then followed them into the body.
contaminated tens of millions of rice farmers is the biggest victims. Rice is the staple of their three meals a day of absolute, some farmers know that there are pollution, but pollution trapped in the rice to sell to buy rice the difference between the net loss, forced consumption of contaminated rice. More farmers are not aware of their own consumption of rice is toxic, they even do not know what heavy metal.
more seriously, almost no heavy metal pollution on land cultivation practices, a large number of contaminated land were in the normal production of rice.
Moreover, the pollution of contaminated land on the output of rice, most of the free market can flow unimpeded. This has led to contamination of rice-producing areas outside the urban and rural residents also have exposure to danger, and how much risk, the current lack of research.
