He said, "I tend to think that the fertilizer into the."Hunan Institute of Geology Professor Qian Tong Ming agrees, he believes, compared with industrial pollution, caused by the unreasonable application of fertilizer pollution, also deserves attention.As one of the three most commonly used fertilizer, phosphate fertilizer is widely used in agricultural production, which is the main raw material of phosphate rock,tiffany outlet, a natural concomitant of cadmium per kg of phosphorus content,tiffany italia, ranging from a few milligrams to several hundred milligrams."But in Hunan agricultural production,tiffany outlet, this standard has not been effectively implemented." Tong Qian Ming publicly stated that "in most rural areas of Hunan,veste barbour homme, farmers buy bags of fertilizer from fertilizer stores,hollister france pas cher, according to a bag per acre ( 50 kg) administered traditions, rather than based on actual soil fertility adjustment. "According to Tong Qian Ming saying Hunan to increase, it will use a large area fertilizer. Fertilizer applied to the fields, cadmium accumulate a certain extent, it will lead to excessive cadmium content of the soil, and finally lead to contamination of crops.With respect to the terms of fertilizer caused soil pollution in Hunan argument.
but the official did not take it seriously. A 2008 "Geological Bulletin,abercrombie pas cher," said the Dongting Lake area late rice cadmium exceeded 41.67%, almost all vegetables cadmium exceeded.The report on the Hunan rice pollution "risk assessment" is more show,abercrombie et fitch, "the researchers in Hunan sample of the 112 samples of rice and rice samples Determination of Heavy Metals in which arsenic, lead and cadmium, the sample covers Zhuzhou, Xiangtan, Hengyang ,louboutin soldes, 10 city Changsha, Shaoyang, Yueyang, Yiyang and Changde and other samples of rice cadmium content in line with national standards and only 64 percent. "The report stands for "Hunan market and polluted rice arsenic,doudoune parajumpers, lead, cadmium pollution and health risk assessment,barbour paris," by Chinese Academy of Sciences Ecological Environment Research Center.
College of Resources and Environment, Hunan Agricultural University, Central South University of Forestry and Technology College of Forestry,peuterey prezzi, Shandong Province Analysis and Testing Center four institutions in 2010 have completed.The study also elected the 10 local special smelting area place, such as Changning Hengyang, Zhuzhou Qingshuitang other regions. The results show that more than heavy metal contamination rate of these 10 regions in 90 percent of samples of rice, brown rice lead content exceeding the national average of standard four times the average of the equivalent of the lead content of chaff nearly six times the national standard. "Although Youxian official informed that within 10 km around the rice business without excessive heavy metal cadmium content business, but according to Die Zeit reporter survey, soil heavy metals pollution Youxian a long time,nike tn 2014, many years ago in a secret is disclosed.According to Youxian peach Township some villagers say.
foreign scholars believe that excessive levels of cadmium in rice,collana tiffany, has its roots in the soil is contaminated.Zhejiang Province Agricultural Safety Standards and Testing Technology key scientific and technological innovation,louboutin paris, said team leader Professor Zhu Cheng, cadmium exceeded rice, root in the soil was contaminated. "Rice has a lot to absorb cadmium properties after water and soil pollution caused by heavy metals, rice grown in contaminated soil, transport through the root, stem,hollister kids, leaf absorbed into the grain, causing the accumulation of heavy metals in rice." Zhu Cheng,soldes hollister pas cher, said.In Youxian official notification said cadmium exceeded rice raw materials are received from local farmers, no heavy metals business enterprises around within 10 km.For this argument, Zhu Cheng believes around 10 km no heavy metal soil contamination can not be excluded companies, have to check whether irrigation water and other contamination.Professor of Resource and Environment College of Environmental Science and Engineering,abercrombie e fitch, China Agricultural University also expressed a similar view, he believes that "rice cadmium exceeded mainly due to soil contamination." said, do not rule out this possibility, the heavy metal content in soil in Hunan Province background values higher than elsewhere. Coupled with the irrational exploitation and sewage, soil heavy metal pollution will be more serious.Heavy metal pollution has already sounded a warningYears ago on Hunan rice cadmium exceeded the warning has been sounded frequently.
the town a few years ago there is a lot of heavy metal refining small workshops, and later forced to close. Even some zinc oxide plant.Those familiar with the production process zinc oxide villagers revealed that in the process of refining zinc oxide.
