ABSTRACT

The purpose of this study was to analyze the levels of lead (Pb), cadmium (Cd), aluminum (Al), zinc (Zn), cooper (Cu) and chromium (Cr) in the water of drinking fountains distributed in the Campus of the University of São Paulo. Ribeirão Preto, Brazil. Thirty random samples were collected in different parts of the Campus that were analyzed by Atomic Absorption Spectrophotometry. According to WHO's Drinking Water Guidelines; lead, cadmium and zinc were found in concentrations higher than those recommended in 40 per cent, 20 per cent and 13 per cent of the samples, respectively. The results were analyzed considering nutritional and toxicological aspects related to the presence of essential and toxic elements for the human being. Reviewing the regulatory limits established in ten countries of America, authors focus in the necessity to find a consensus in the establishment of the higher levels of heavy metals in potable water. The tolerable daily intake, have to be the basis to assure the prevention of diseases associated with a long-term ingestion of these elements through foods.

ABSTRACT

Foram admitidos no Hospital das Clinicas da FMRPUSP, durante os anos de 1983 a 1988, 494 pacientes vitimas de acidentes ofidicos e escorpionicos que receberam soro antiveneno (SAV) e nos quais foi avaliada a frequencia e tipo das manifestacoes imediatas, bem como o valor prognostico do teste de sensibilidade. Do total de pacientes vitimas de ofidismo, 82 (25,6 por cento) apresentaram reacoes imediatas, das quais as mais comuns foram as cutaneas, isoladas (40 por cento) ou associadas com sintomas respiratorios (19 por cento), seguidas de manifestacoes gastrintestinais (17 por cento). Choque anafilatico foi detectado em 10 pacientes (12 por cento). Em relacao aos acidentes escorpionicos, reacoes imediatas foram observadas em 13 pacientes (7,5 por cento), tambem com predominio de lesoes cutaneas. Sintomatologia cardiocirculatoria foi detectada em apenas 1 paciente. Devido ao baixo valor preditivo positivo (31,8 por cento) e a baixa sensibilidade (54,6 por cento), propomos que o teste de sesibilidade intradermico seja abolido da rotina de atendimento de urgencia aos pacientes vitimas de acidentes por animais peconhentos. Anti-histaminicos (bloqueadores dos receptores "H IND. 1" e "H IND. 2") e corticosteroides devem ser administrados por via parenteral anteriormente a soroterapia, no sentido de prevenir...
