Notice of public comment period.

# SUMMARY:

EPA is announcing a 45-day public comment period for the draft document titled, “Lymphohematopoietic Cancers Induced by Chemicals and Other Agents: Overview and Implications for Risk Assessment” (EPA/600/R-10/095A). The draft document was prepared by the National Center for Environmental Assessment within EPA's Office of Research and Development. The draft document provides an overview of the types and mechanisms underlying the lymphohematopoietic cancers induced by chemical agents and radiation in humans, with a primary emphasis on leukemia and leukemia-inducing agents. In addition, the document also focuses on how mechanistic information on human leukemia-inducing agents can inform risk assessment.
