Abstract: Phosphate fertilizer and raw material in the existing phosphate fertilizer production in Hunan Province were sampled. According to the "ecological index of arsenic, cadmium, lead, chromium, mercury in fertilizer" (GB/T 23349-2009), the pollution index was evaluated. The results showed that the average contents of arsenic, chromium, lead, cadmium, mercury in single superphosphate was 26.78 mg/kg, 18.86 mg/kg, 18.51 mg/kg, 1.55 mg/kg, 1.27 mg/kg respectively. The average contents of chromium, lead, arsenic, cadmium, mercury in calcium magnesium phosphate was 798.39 mg/kg, 9.78 mg/kg, 6.31 mg/kg, 0.67 mg/kg, 0.11 mg/kg respectively. The arsenic, cadmium, lead, chromium, mercury content in most phosphorus fertilizer were lower than the standard. The lead, cadmium, arsenic, chromium in single superphosphate was mainly from phosphor mine and mercury from sulfuric acid. The lead, cadmium, mercury, arsenic, chromium in calcium magnesium phosphate was mainly from phosphate. Under acidic conditions potential risks from cadmium in phosphate fertilizer.for agricultural product safety existed.
