NPI Web page :“Rank 11 of 90
substances”
I advised: the Agency for Toxic Substances & Disease
Registry (ATSDR) in the US had in 1995 determined
lead to be the top priority substance in public health
terms so why not link to the ATSDR website instead?
CERCLA (developed under the Comprehensive
Environmental Response, Compensation and Liability
Act) Priority List of Hazardous Substances places 4
heavy metals (all of which are found in ceiling dust)
in the top 7 of 275 ranked priority toxic substances.
