| 摘 要： | 通过对云南抚仙湖流域磷化工厂附近农田和区域内地表径流污染物含量进行调查分析,结果表明距磷化工厂越近,农田灌溉水、土壤、农作物中污染物含量越高。磷化工生产排放的废水和废渣淋溶废水严重污染了附近农田灌溉水,从而造成农田土壤氟、磷积累,最高分别超过对照农田土壤氟、磷含量35和37倍。相关分析结果表明农作物茎、叶蓄积的高浓度氟、磷主要来源于受磷化工排放废水和废渣污染的农田土壤。

| Abstract: | Pollutants in farmland and surface runoffs were investigated in the surrounding region of phosphate plant in Fuxianhu Lake in Yunnan Province. Results showed that fluoride and phosphorus contents in irrigative waters,agricultural soil and crops were related to distance from phosphate plant. Irrigative water was heavily polluted by wastewater and residue leaching solution discharged from phosphate industry. As a result,large amount of fluoride and phosphorus were accumulated in agricultural soil,which were 3... |
