广州市不同区域水稻质量状况及其污染源探讨

Study on the status of rice quality and pollution sources in different regions of Guangzhou

根据1999年度对部分水稻质量监测结果,认为产品质量为重污染级这一问题,于2001年再选择一些监测点开展水稻质量、生产环境质量监测和评价。结果表明,2001年度水稻质量仍存在受污染问题,污染因子为氟化物、铅、镉和汞,大气污染为主要原因,其次为水质污染。

Some monitoring spots in Guangzhou were selected again to monitor and evaluate the quality and the production environments of rice in 2000, on the basis of the 1999's monitoring results that the qualities of some rice were heavy polluted. The results showed that the polluted problem of rice also existed. The polluted factors were fluorides, Pb, Cr and Hg. The first reason was air pollution, and the water pollution was the second.
