The Hidden Toll of Airborne Lead: Infant Mortality Impacts of Industrial Lead Pollution

This paper uses U.S. Toxic Release Inventory data on industrial air lead emissions to provide IV estimates of the effects of air lead concentration on infant mortality. The causal effect of lead on infant mortality is identified by annual variation in air fugitive lead emissions interacted with wind

本文采用美国有毒物质排放清单（Toxic Release Inventory, TRI）中有关工业空气铅排放的数据，开展工具变量（Instrumental Variables, IV）估计，以量化空气中铅浓度对婴儿死亡率的影响。铅对婴儿死亡率的因果效应，可通过空气中无组织铅排放的年度变化与风况的交互作用得到识别。
