- Abstract
OBJECTIVE: To determine the blood lead levels in children living near an inactive lead foundry in the city of Santo Amaro da Purificacao, state of Bahia, in September of 1998; and to identify factors associated with differences in these levels. METHODS: Cross-sectional study with children between 1 and 4 years of age living within 1 km of the lead foundry. Mothers or guardians of 47 children answered a questionnaire concerning ingestion of clay, soil, plaster and/or other materials (pica), and other relevant epidemiological aspects. The concentration of lead in blood was determined by atomic absorption espectrophotometry. RESULTS: The mean blood lead level was 17.1 +/- 7.3 micro g/dL. Blood lead levels were approximately 5 micro g/dl greater among children with pica, regardless of age, visible presence of scum surrounding the home, employment status of the father, family history of lead poisoning, and malnutrition. CONCLUSIONS: The environmental legacy of the lead foundry, which was shut down in 1993, continues to represent a relevant risk factor for increased blood lead levels in children, especially those presenting pica.
