燃煤型砷中毒病区居民总摄砷量与病情的相关研究

Correlation of total arsenic intalce and incidence of its poisoning in coal type endemic

通过对燃煤污染型砷中毒不同流行强度的几个有代表性地区村和对照点的调查，发现其主要砷源均来自高砷煤燃用污染，从空气和烘炕后玉米、辣椒中摄入砷量占总摄砷量的９０％以上；总摄砷量与疾病流行强度、煤砷、尿砷、发砷含量呈直线相关，推算出四个回归方程。并对燃煤型砷中毒的病区划分及选用的指标提出了建议。

This paper describes an investigation in some arsenic poisoning endemias,where the main sources of arsenic were from coal smoke pollution.The arsenic intake from air dried maize and capscium made up over 90% of the total amount of arsenic intake.The prevalence and the arsenic contents of coal urine and hair showed a liner correlation with the total arsenic intake.And four regression equations were develeped.A suggestion was made concerning the standard of delimitation of arsemic poisoning endemic caused by burning coal.
