“…In the early 1970s, the federal government enacted guidelines for lead screening in children (Tesman & Hills, 1994). Data from these screenings provided new information indicating that children who had high (>10μg/ dL) but not toxic (>60μg/dL) BLLs also showed defi cits in behavior, learning, and intelligence.…”

“…In response to this research, the CDC again reduced acceptable BLLs in children to 25μg/dL and eventually to 10μg/dL. Researchers wondered, however, if even lower levels of lead negatively affected children (CDC, 1991;Tesman & Hills, 1994).…”

“…In 1994, the Society for Research in Child Development (SRCD) published a Social Policy Report describing the most recent research concerning the effects of lead on children, and suggested possible ways of protecting children from exposure (Tesman & Hills, 1994). In 1991, the EPA safety threshold for Blood Lead Level (BLL) was set at 10μg/dL, and any BLL greater than this was considered unsafe.…”

T he detrimental effects of lead exposure in children have been known for over 100 years. Although a few initial measures implemented about 30 years ago were effective in somewhat reducing levels of lead exposure in children, relatively little has been done recently from a policy perspective to protect children from lead. We now know from recent research that much more work is needed. Recent events highlighted in the media show that several urban communities still have unacceptable levels of lead in water systems. Early research identifi ed high levels of lead as being particularly detrimental to children's intellectual and behavioral development. However, new studies have discovered that lower levels of lead, levels once thought safe, also cause considerable damage to children's developmental outcomes. This social policy report summarizes new data on the intellectual, academic, and behavioral defi cits seen in children exposed to both low and high levels of lead, discusses the biological and neurological mechanisms of lead poisoning, explores sources of environmental lead exposure and lead abatement practices, shows that current federal and state-level child screening and lead level reporting practices are inadequate, and makes policy recommendations centered on increasing education, intensifying abatement efforts, strengthening and regulating mandatory screening practices, and reducing the federal threshold of allowable levels of lead.sharing child and youth development knowledge volume 24, number 1 2010Social Policy Report V24 #1

“…O desempenho cognitivo também piorou, ainda que com índices baixos, quando a exposição era por longos períodos (Tesman, Hills, 1994;Thomson et al, 1989). Bellinger (1995) afirma também que, mesmo em quantidades relativamente pequenas, o chumbo pode causar rebaixamento permanente da inteligência em crianças, resultando em prejuízos escolares e distúrbios psicológicos.…”

ResumoPesquisas mostram que a presença de metais, acima dos níveis permitidos pela legislação, representa riscos para a saúde humana. Crianças são mais vulneráveis aos efeitos do chumbo, que pode causar rebaixamento permanente da inteligência e outros distúrbios associados, como baixo desempenho escolar. O objetivo do estudo foi avaliar o rendimento escolar de crianças contaminadas por chumbo, comparando-o com o daquelas que não estavam contaminadas. Participaram três grupos com 25 crianças cada, de seis a treze anos; o Grupo 1, com crianças contaminadas por chumbo; o Grupo 2, com crianças com chumbo zero comprovado, embora residentes no local da contaminação; e o Grupo 3, com crianças de um bairro com características sociodemográficas semelhantes às do local da contaminação, porém, sem contaminação comprovada. Para a avaliação do rendimento escolar, utilizou-se o Teste de Desempenho Escolar -TDE. Os resultados mostraram melhor desempenho para o Grupo 2 (não contaminadas) e pior para o Grupo 1 (contaminadas). Palavras-chave: contaminação por chumbo, teste de desempenho escolar, rendimento escolar.
