Mitigate risks of human exposure to chromate copper arsenate\r\n(CCA) and lead.<\/o:p><\/p>","intervention":"This WELL feature requires addressing risks\r\nassociated with human exposure to chromate copper arsenate (CCA) in existing\r\nwood structures and lead in soil, playground equipment and artificial turf.","issue":"In the 2000s, the application of CCA (or\r\n\u2018pressure-treated wood\u2019) was restricted due to health concerns connecting its\r\npresence to arsenic exposure to humans, animals and food crops, and1<\/sup> exposure to arsenic is known to cause increased\r\nrisk of skin, liver, bladder and lung cancers.2<\/sup> However, prior to its restriction, CCA was a\r\nwidely used wood treatment for decades. As a result, CCA presence in our\r\nenvironment still poses as a threat to our health. Additionally, chromates\r\nwhich are catalogued as carcinogenic to humans3<\/sup> can be inhaled if CCA-containing wood is ever\r\nburnt. Among other existing external hazards is lead, which may be present in\r\npaints used on outdoor structures and playgrounds.4<\/sup>\r\nLead may also contaminate soils upon chipping, in fibers of artificial turf5<\/sup> and in some loose rubber.6<\/sup>
","evidence":"Identifying and remediating hazards associated\r\nwith CCA and lead should reduce risk of exposure to and dispersion of\r\ncontaminants in the environment through leachates. Although not all routes of\r\nexposure and bioavailability of lead are fully understood,6<\/sup> ingestion and inhalation of lead-containing\r\nparticles may occur due to contaminated paint or rubber crumbs and, thus, from\r\na precautionary standpoint, testing for lead is recommended.7<\/sup>","implementation":"","impact":"","max_points":0,"concept_id":1740,"slug":"existing-hazardous-materials-management-exteriors","gbd_exists":null,"review_summary":null,"citations":"
