The article by Norman et al1 contributes additional evidence that vinyl miniblinds are a potential source of lead exposure. Unfortunately, it does not answer the real question of how significant a risk these blinds pose to young children as a whole. Despite the almost ubiquitous presence of miniblinds in homes and day-care centers, the prevalence of elevated blood lead levels continues to decline nationally, and certain geographic areas continue to show almost no lead problem.2- 4 Miniblinds are thus unlikely to be a major contributor to blood lead elevation in most cases. However, the variable rates of lead dust formation on these blinds,5 coupled with the uncertain degree of compliance with recommendations to remove them from homes, leaves open the possibility of ongoing risk to children.
