Este estudo pretendeu verificar a percepção que as crianças e os seus responsáveis têm sobre a intoxicação por chumbo e quais implicações relatam sobre o fato. Participaram desse estudo 50 crianças intoxicadas, de ambos os sexos, com idade de 4 a 13 anos e seus genitores e/ou responsáveis. Os participantes responderam a entrevistas estruturadas que buscaram investigar o que é o chumbo, como se dá a intoxicação, seus efeitos no organismo infantil, possíveis alterações no ambiente em função da contaminação e, o que os adultos julgam que melhoraria o desenvolvimento das crianças intoxicadas. Os resultados indicaram a falta de compreensão de vários entre os aspectos investigados e a evolução do conhecimento com o aumento da idade. Tais dados poderiam subsidiar a proposição de políticas de saúde pública adequadas e efetivas para o atendimento a essa população, assim como a divulgação de informações corretas sobre o acontecido e seus desdobramentos.

This is a cross-sectional study with a randomized choice of individuals aiming at studying the validity of the Brazilian biological exposure limits applied to lead level in the blood (PbB) and delta-aminolevulinic acid in the urine (ALAU), which are 60 μg/dl and 10 mg/g.creat., respectively. For this purpose, twenty workers, whose PbB and ALAU values have been below these limits over the past two years, were selected at random at a battery production plant in the State of S. Paulo, Brazil. The workers were submitted to a peripheral nerve conduction study. The results were compared with those obtained for workers of a control group also chosen at random. The lead workers showed a decrease in the velocity conduction of the radial nerves. Comparing this group with a randomized control group, a significant difference was observed (p-value = 0.0067). The results suggest that the Brazilian biological exposure limits above should be rearranged.

Thus, twenty workers, whose PbB and ALAU values have been below these limits over the past two years, were selected at random at a battery plant in the State of S. Paulo, Brazil. The workers were submitted to a variation of the WHO Neurobehavioral Core Test Battery. The results were compared with those obtained for workers of a control group also chosen at random. The lead workers showed memory, mood and motor coordination disorders. Comparing these results with those obtained from the control group, a significant difference was observed (p-value < 0.02). The results indicate that the Brazilian biological exposure limits above should be reconsidered.

The present study reports the occurrence of lead poisoning in a male, 2 year-old mongrel dog attended at UNESP Botucatu Veterinary Hospital. The animal was brought to the hospital with claim of gastrointestinal and nervous disturbs for 10 days, worsening in the last 24 hours. After unsuccessfully attempts to control status epileticus, the animal died. Hematological evaluation revealed significant rubricytosis and basophilic stippling, highly suggestive of lead poisoning. Serum lead concentration confirmed toxic levels of this element. Necropsy evidenced the presence of foreign bodies in stomach (one stone and two metallic objects) and, microscopically, characteristic inclusions in renal parenchyma. Fragments obtained from liver and kidneys revealed lead concentrations of 0, 8 μg/g and 25 μg/g, respectively, which in association to clinical signs of saturnism, determined the diagnosis of lead poisoning.
