摘要：In order to make a pollution survey assessing the levels of Cd and Hg, this study drew the pollution spatial distribution map by using inverse distance weighting interpolation to analyze 33 sampling points in a phosphorus chemical plant. The results indicated that the content of Cd in 89.5% areas and Hg in 73.2% areas were above the standard. According to the pollution spatial distribution maps, the points of high Cd value are concentrated in brimstone pools and the points of high Hg value concentrated in brimstone pools, phosphoric acid workshop and storage.
