Because of its prevalence, particularly as a combustion by-product, 1,3-butadiene is a particularly important air toxic. It plays a significant role in all air toxics regulatory efforts in the US. The various requirements of the Federal Clean Air Act (CAA) dealing with air toxics are reviewed and the significance of 1,3-butadiene in each area is discussed in light of what is known about its emissions and health effects. The impacts of the changes in the understanding of 1,3-butadiene cancer potency over the past 15 years demonstrates the possible impact of such benchmarks and the importance of using the best science in understanding public health risks.
由于其普遍性，尤其是作为一种燃烧副产物，1,3 - 丁二烯是一种特别重要的空气有毒物质。它在美国所有空气有毒物质监管工作中都发挥着重要作用。本文回顾了美国联邦《清洁空气法》（CAA）中关于空气有毒物质的各项要求，并根据已知的1,3 - 丁二烯排放情况及其对健康的影响，讨论了其在各个领域的重要性。过去15年中对1,3 - 丁二烯致癌潜力认识的变化所产生的影响，证明了此类基准可能产生的影响以及运用最佳科学知识来理解公共健康风险的重要性。
