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.
