RESUMO - A determinação da protoporfirina-zinco (PPZ) por meio de
um hematofluorímetro portátil vem sendo descrita como
apreciável contributo no contexto da vigilância de saúde
de trabalhadores expostos a chumbo.
Num estudo abrangendo 178 indivíduos (cerca de 60% dos
quais referenciados como profissionalmente expostos
àquele metal) foi testado o método e a técnica propostos e
estudada a validade dos resultados assim obtidos.
Concluiu-se que a determinação da PPZ em sangue colhido
por punção capilar, por meio de hematofluorímetro portátil,
oferece resultados fiáveis, permitindo, deste modo, o
recurso a esta técnica de fácil execução e baixo custo.
SUMMARY - The determination of zinc-protoporphyrin (ZPP) using a portable hematofluorometer, has been described as an outstanding contribution for health surveillance of workers exposed to lead. In a study of 178 individuals (about 60% of them referenced as occupationally exposed to that metal) the proposed method and techniques were tested and the validity of the obtained results was studied. It was concluded that the determination of ZPP using a portable hematofluorometer, in blood collected by a fingerstick, gives warrantable results enabling, therefore, the use of this technique which is of easy accomplishment and low cost.
