根据对1210份发汞测得的结果认为发汞值属正偏态分布,但可以通过对数变换成为对数正态分布进行统计分析。发汞值与日均汞摄入量有关,监测发汞值可以推算人体环境汞暴露的水平,并提出了推算的方法。
Based on the results of 1210 mercury measurements, the hair mercury values are considered positive skewed but can be statistically analyzed by logarithmic transformation to log normal distribution. Hair mercury value and daily average mercury intake related to the monitoring of hair mercury value can estimate the level of human environmental mercury exposure, and put forward the calculation method.
