Dust that settles in and around homes in the Trail area may contain lead as a result of air emissions (mainly historical) from the smelter. Lead dust may also come from older, chipping indoor and outdoor paint. If a young child puts their hands in their mouth, they may unintentionally ingest lead from dust on their hands. Keeping dust down inside and outside the home, especially in drier months, is one way to reduce potential ingestion by children.
