This article analyzes the early years of 20th-century air pollution control in Los Angeles. In both scholarship and public memory, mid-century efforts at the regional level were overshadowed by major federal developments, namely the Clean Air Act and creation of the US Environmental Protection Agency in 1970. Yet the mid-century local experience was highly consequential and presaged many subsequent challenges that persist today. The article begins with an exploration of the existential, on-the-ground misery of smog in Los Angeles during the 1940s and 1950s. The article examines the role that scientific evidence on smog did and did not play in regulation, the reasons smog control galvanized support across various constituencies in the region, and, finally, some of mid-century air pollution's limits.
本文分析了 20 世纪早期洛杉矶的空气污染控制情况。在学术和公众记忆中，区域层面的 20 世纪中期努力被联邦层面的重大发展所掩盖，即 1970 年的《清洁空气法案》和美国环境保护署的成立。然而，20 世纪中期的地方经验具有重要意义，并预示了许多至今仍然存在的后续挑战。本文首先探讨了 20 世纪 40 年代和 50 年代洛杉矶烟雾带来的生存危机和地面苦难。本文考察了烟雾方面的科学证据在监管中的作用和局限性，烟雾控制在该地区各个利益相关方中获得支持的原因，以及 20 世纪中期空气污染的一些局限性。
