云南傣族生活习惯对饮水砷健康危害的影响

目的了解云南傣族人喝生水、吃生菜、生肉对砷健康危害保护作用的原理,为地砷病的防治提供理论依据。方法采用定性到定量的研究方法:将高砷饮水健康危害影响的多因素条件logisitic回归分析研究中发现的2个保护因素:喝生水、吃生菜做实验室定量检测分析。结果经加热后,水、蔬菜、肉中的砷含量增加,并且随着加热时间的增加,砷含量也在增加,用砷含量高的水煮沸后的蔬菜、肉,砷含量增加的速度更快。结论傣族喝生水、吃生菜、生肉的生活习惯,对砷的机体损伤的保护作用,是因为生水、生菜、生肉中的砷含量低,从而减少了砷的摄入量。因此,在其他高砷地区,如不能及时改水,采取减少加热时间,提倡急火快炒的烹调方法,可能是一条经济实惠的地砷病防治措施;我国现行的水砷标准被修订为0.01 mg/L是科学合理的。
