Health-based benchmarks for short-term and acute exposures did not exist for pollutants of concern resulting from the collapse of the WTC. For asbestos, EPA used benchmarks originally designed for other purposes to assess potential health risks from breathing the air following the WTC collapse. Because health-based benchmarks for short-term exposures did not exist for most of the other pollutants, EPA revised benchmarks for lifetime (30-year) exposures to develop screening levels for short-term (1-year) exposures. Further, health-based benchmarks did not exist for assessing the risk to human health from exposure to the combination of air pollutants that were emitted.
