摘要
分析了太原市夏季大气中16种羰基化合物的情况,结果表明,太原市夏季羰基化合物总质量浓度为19.40μ/m^3,浓度最高的物质为甲醛、乙醛和丙酮,共占77.21%。C1/C2和C2/C3值分别为3.85和7.34。太原市羰基化合物主要受到人为因素的影响。终生癌症风险(ILTCR)评估显示,甲醛与乙醛的ILTCR均超过了1×10^-6,存在显著的癌症风险。
In this paper,sixteen carbonyl compounds were analyzed in Taiyuan City during summer.The results showed that total concentrations of carbonyls were 19.40μg/m^3 in summer.Formaldehyde,acetaldehyde and acetone were the three most abundant carbonyls,accounting for 77.21%.The ratios of C1/C2 and C2/C3 were 3.85 and 7.34.Human activities were the main sources of carbonyls in Taiyuan City.The Lifetime Cancer Risk(ILTCR)assessment showed that the ILTCR of both formaldehyde and acetaldehyde exceeded the value of 1×10^-6,indicating a significant cancer risk.
