Lead poisoning is a significant environmental disease. 89% of the apartments in Manhattan’s Inwood and Washington Heights communities contain lead based paint. If lead paint is found in an apartment the landlord is required by law to remove, abate, encapsulate the lead paint. It requires that the work be done by licensed professionals. Lead poisoning can result in severe brain damage to an infant. If lead paint is found in the apartment remove the children until the woek is completed. NYC Department of Health provides safe-houses where people can stay with their children during the renovation of the apartment.
