磷肥厂氟化物对周边农作物的危害与防治

Harm and Countermeasures of Fluoride Emissions from Phosphate Fertilizer Plant on the Surrounding Crops

对云南三环化工有限公司厂界周边农作物中氟化物含量进行常年的跟踪监测,分析氟化物排放对厂界周边农作物的危害。结果表明,氟化物污染危害程度与烟囱排放高度、气象条件、排放浓度及农作物本身抗性等因素有关,提出了氟化物污染的防治对策和建议。

Through tracking and monitoring the fluoride contents in surrounding crops of Yunnan Three Circles chemical Co.,Ltd,the harm of fluoride pollution on crops was analyzed.The results showed that the pollution degree of fluoride was related to the chimney emission height,meteorological conditions, the pollution source emission concentration,and crop itself resistance and other factors,some countermeas-ures and suggestions for the prevention and control of atmospheric pollution by fluoride were put forward.
