【摘要】 对一个磷肥厂周围12个村庄的人发、粮食和饮水硒、碘、氟进行了测定,利用改进的模糊数学中的群体识别法对以上数据进行分析,所得结果表明,受污染较重的几个村庄人体硒、碘、氟含量确实受到来自磷肥厂的大气高浓度硒、碘、氟的直接影响.更多还原

【Abstract】 Samples of drinking water, rice and human hair were collected near a phosphate fertilizer factory for determination of Se, I and F contents. A modified procedure of fuzzy recognition was applied to isolate the contribution of the atmospheric pollutants on human hair contents of the elements from those of drinking water and rice. The results of the approach were in accordance well with the outcome of direct measurements of the atmospheric pollutants.更多还原
