When Did Lead Paint become an Important Issue?
In the early 1970s, the relationship between lead and physical and mental impacts became better understood and in particular, the exposure of children in residential dwellings was a prime focus of concern. The recent increase in interior renovations of older residential buildings has raised concern about lead being released into indoor air. Also, where painted surfaces are not in good condition, children have been known to pick and remove paint chips, ingesting or inhaling lead dust and particles.
In response to concerns, many laws have been passed to limit the concentration of lead used in various products; including exterior and interior paints, furniture varnishes and other household products. What many did not realize at the time was that many items used by the public, and especially children, still contained lead. Items like paints used on toys and playground equipment may still contain high lead concentrations.
