EPA has announced that the First External Review Draft of the Integrated Science Assessment (ISA) for Lead (Pb) has been made available for independent peer review and public review. This draft ISA represents a concise synthesis and evaluation of the most policy-relevant science and will ultimately provide the scientific bases for EPA’s decision regarding whether the current standards for Pb sufficiently protect public health and the environment.
