2Químico, CNEN (Comissão Nacional de Energia Nuclear).RESUMO -Para se proceder a uma investigação em misturas minerais, foi realizada uma pesquisa quantificando o elemento chumbo em diferentes formulações, comercializadas no Estado do Paraná. O xenobiótico foi determinado pela técnica de espectrofotometria de absorção atômica. Em 29 amostras analisadas, 21 tiveram valores superiores aos 10 mg kg -1 recomendado como máximo valor aceitável por MALETTO (1986). Os valores encontrados oscilaram entre 2,7 e 256,4 mg kg -1 , com o maior resultado sendo encontrado numa amostra de sal mineral colhida no município de Catanduvas. Os resultados demonstram a urgente necessidade de monitoramento junto aos fabricantes, pois algumas misturas minerais são eminentemente perigosas, possibilitando efeitos cumulativos tóxicos de chumbo inorgânico aos bovinos.Palavras chave: sal mineral, chumbo, bovinos. , the maximum concentration recommended by MALETTO (1986). The concentrations of lead found ranged from 2.7 to 256.4 mg kg -1 , the highest value being assayed in a sample commercialized at Catanduvas city. These findings call for the need of a careful industrial monitoring because some mineral mixtures contain sufficient lead to cause bovine toxicity and, through the trop;hic chain, reach the human population. ABSTRACT -
Os domicílios que possuíam poço ou nascente como principal local de captação de água, (13,1%) não possuíam canalização dessa água ao interior da residência e na zona rural o principal destino para os dejetos de banheiro e sanitário ocorre em fossa rudimentar e associado a isso, grande parte do destino do lixo (40,7%) é a queima nas residências. Conclusão: As condições da utilização da água de consumo, do destino das águas residuais (esgoto) e do lixo doméstico encontrados possuem características poluidoras e que necessitam de intervenção educacional e social. As saúdes individuais e coletivas podem estar sendo afetadas pela falta de adequação do uso dos recursos naturais. DESCRITORESPerfis Sanitários. Abastecimento Rural de Água.

As part of this global context, it is important to diagnose the sanitary conditions of rural areas and small communities in Brazil. Objective: To diagnose the sanitary conditions in a municipality of Western Santa Catarina state. Material and Methods: This was a crosssectional population-based study carried out in the municipality of Palmitos, Western Santa Catarina state. The sample was self-weighted into two selection stages, census sector and households. A descriptive analysis of the variables was performed. Results: Three-hundred sixty-six participants over 15 years old from one-hundred thirty-six households were interviewed. Households had a well or a spring as the primary location of water collection; 13.1% had no channeling of the water into the house; in rural areas, the main destination for the bathroom and sanitary waste occurs is crude tanks; in addition, much of the garbage (40.7%) is burned in the houses. Conclusion: The conditions of use of drinking water, and the destination of the waste water (sewage) and household waste present polluting characteristics in need of educational and social intervention. Individual and public health may be affected by the lack of appropriate measures concerning the use of natural resources.
