摘　　要：通过了解目前市售国标ⅥB车用汽油中苯含量水平,为车用汽油职业危害风险管理提供科学依据。以国内某大型油品销售企业为研究对象,采用方便抽样法,收集其下属的6家省级油品销售公司的国标ⅥB车用汽油质量检验报告,分析不同地区、不同标号、不同类型及不同检测方法的国标ⅥB车用汽油中的苯含量(体积分数)水平,发现收集的国标ⅥB车用汽油质量检验报告中苯含量(体积分数)均低于0.8%,平均值为(0.34±0.17)%。按照地区进行分析,广东地区国标ⅥB车用汽油中苯含量(体积分数)最高为(0.55±0.13)%,与其他地区之间的差异有统计学意义(P<0.01);上海地区为(0.41±0.13)%、天津地区为(0.38±0.20)%次之,二者与其他地区之间的差异有统计学意义(P<0.01),但二者之间差异无统计学意义(P>0.05);山东地区为(0.28±0.14)%、江苏地区为(0.27±0.16)%和北京地区为(0.27±0.12)%在最低区间且较为接近,三者之间差异无统计学意义(P>0.05)。按照汽油标号进行分析,92#国标ⅥB车用汽油中苯含量(体积分数)最高为(0.44±0.17)%,95#车用汽油次之为(0.31±0.15)%,98#车用汽油最低为(0.22±0.12)%,各标号车用汽油之间差异有统计学意义(P<0.01)。在汽油类型方面,乙醇车用汽油与普通车用汽油样品中苯含量(体积分数)之间差异无统计学意义(P>0.05)。在检测方法方面,采用SH/T 0713—2002测定车用汽油样品中的苯含量(体积分数)值略高于GB/T 30519—2014,二者之间差异有统计学意义(P<0.05)。目前市售的国标ⅥB车用汽油中苯含量在不同地区、不同标号及不同检测方法方面存在差异,但整体苯含量水平较低,不属于含苯产品,建议按照非含苯产品开展职业病危害因素识别、检测与职业危害风险管理。Taking a large domestic oil sales enterprise as the research object,convenient sampling method was used to collect the national standard ⅥB automobile gasoline quality inspection report of 6 provincial oil sales companies,and analyze the benzene content(volume fraction)level of national standard ⅥB automobile gasoline in different regions,different labels,different types and different detection methods.The benzene content(volume fraction)in the collected national standard ⅥB automobile gasoline quality inspection report was lower than 0.8%,and its average value was(0.34±0.17)%.According to the analysis of regions,the benzene content(volume fraction)in national standardⅥB gasoline in Guangdong area was the highest(0.55±0.13)%,and the difference was statistically significant(P<0.01).Shanghai area(0.41±0.13)% and Tianjin area(0.38±0.20)%followed,and there was statistical significance between them and other areas(P<0.01),but there was no statistical significance between them(P>0.05).Shandong area(0.28±0.14)%,Jiangsu area(0.27±0.16)% and Beijing area(0.27±0.12)% were in the lowest range and relatively close,and there was no statistical significance among them(P>0.05).According to the gasoline label analysis,the benzene content(volume fraction)in 92# national standardⅥB gasoline was the highest(0.44±0.17)%,followed by 95# gasoline(0.31±0.15)%,98# gasoline was the lowest(0.22±0.12)%,and the difference between the gasoline labels was statistical ly significant(P<0.01).In terms of gasoline type,there was no significant difference in benzene content(volume fraction)between ethanol motor gasoline and ordinary motor gasoline(P>0.05).In terms of detection methods,SH/T 0713—2002 was used to determine the benzene content(volume fraction)of automotive gasoline samples,which was slightly higher than that of GB/T 30519—2014,and the difference between the two was statistically significant(P<0.05).At present,the benzene content of national standard ⅥB automobile gasoline on the market is different in differ
