摘　　要：[目的]分析1953～1989年上海市苯的监测资料 ,确定每年苯的暴露强度等级。[方法]用SAS软件包对苯的监测资料进行统计描述 ,并进行暴露强度分级。[结果]1953～1989年上海市苯的监测资料呈偏态分布 ,样品数和算术均数波动较大 ,离散程度高。总的算术均数为132.7mg/m3;中位数为2.8mg/m3。上海市苯的暴露水平总体上呈下降趋势。[结论]通过汇总分析表明 。Objective Analyzing and grading the intensity of occupational benzene exposure during1953～1989in Shanghai.[Methods]SAS programing on the benzen exposure data fromthe Job-Exposure Matrix data-base of Shanghai.[Results]Data of51,128measurements,at26,000sites,of benzene in the workplace air were analyzed.The distribution of spectrum was greatly biased due to44%of the data were zero.It did not fit the Gaussian distribution.The arithmetic average was132.7mg/m 3 and the median was2.8mg/m 3 .There were peaks during the years of“Great Leap Forward”and“Cultural Revolution”.However,the trend of declining was obvious since1970.Gradation of the median of exposure was categorized and listed.[Conclusion]The range of occupational exposure to benzene in Shanghai during1953～1989was wide.Though the arithmetic average is rather high,zeros occupied44%of the spot samples in monitoring.Taking median value as index for the exposure intensity is an appropriate and acceptable way.
