PPG has released a new policy brief by Adam Hains titled “Lead Poisoning: Triggers and Thresholds.” Hains reviews the basic framework of federal and state laws aimed at preventing lead poisoning.  Given the growing body of research that even small amounts of lead cause can decrease cognitive performance and increase behavioral problems, Hains suggests that New York State lower its threshold of concern and supply additional funding, so that more children receive case management services and more units get their lead problems abated.
