Abstract

The major components in gasoline vapor generated during tank truck loading operations are identified. By analyzing 95 separate gasoline vapor samples, a mean Threshold Limit Value (TLV) for mixtures of about 300 ppm is calculated using 1976 TLV's for the individual hydrocarbons, if available. For compounds without an assigned TLV, a safe exposure value is estimated. Maximum levels of leaded gasoline additives tetraethyl/tetramethyllead, ethylene dibromide and ethylene dichloride are also estimated.

摘要

确定了油罐车装卸作业过程中产生的汽油蒸气中的主要成分。通过分析95个单独的汽油蒸气样本，如果可以获得1976年各碳氢化合物的阈限值（TLV），则使用这些值计算出混合物的平均阈限值约为300 ppm。对于没有指定阈限值的化合物，估计其安全暴露值。还估计了含铅汽油添加剂四乙基/四甲基铅、二溴乙烷和二氯乙烷的最大含量。
