国标ⅥB车用汽油中苯含量分析
Analysis on Benzene Content in Chinese Standard ⅥB Motor Gasoline
摘要
Abstract
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 con-tent(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 standard ⅥB 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 Tian-jin 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 standard ⅥB gasoline was the highest(0.44±0.17)%,fol-lowed by 95#gasoline(0.31±0.15)%,98#gasoline was the lowest(0.22±0.12)%,and the difference be-tween the gasoline labels was statistically significant(P<0.01).In terms of gasoline type,there was no signifi-cant 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(vol-ume 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 na-tional standard ⅥB automobile gasoline on the market is different in different regions,different labels and dif-ferent detection methods,but the overall benzene content level is low,and it does not belong to benzene-contai-ning products.It is recommended to carry out occupational hazard factors identification,detection and occupa-tional hazard risk management according to non-benzene-containing products.关键词
