摘要
某砖瓦厂排放的废气造成附近水稻严重减产。通过对大气、土壤、河水和水稻等样品的分析,结合水稻开花阶段的气象条件研究表明:砖瓦厂排放的气态氟化物是造成水稻减产的主要因子,受害的程度与离厂的远近和水稻开花期间的天气状况密切相关。最后,对防治该厂的氟污染提出了一些建议。
Fluoride emission from certain brickfield caused severe reduction of rice output nearby the factory. After analysing the contents of fluoride in the air, water, soil, rice and investigating the weather condition, we concluded that the gaseous fluoride of brickfield was the main factor that made reduction of rice output, the suffered degree was closely related with the distance from the factory and condition of weather during the blossom of rice. Some suggestions were provided for controlling the fluoride pollution.
