Resumen
O objetivo do presente trabalho foi de determinar a concentração dos bifenilos policlorados (PCBs) 28, 52, 138, 153 e 180 em amostras de soro de indivíduos do sexo masculino, e de relacionar estes valores com os índices de antígeno prostático específico (APE) previamente pesquisado na população de estudo. A extração dos compostos foi realizada por hidrólise ácida, seguida da determinação e quantificação por meio de GC-μECD. Os PCBs 28 e 52 apresentaram-se abaixo do limite de quantificação em todas as amostras analisadas. Dentre os compostos detectados, o PCB 138 foi o mais frequente (75%) e de maior valor médio (2,05 ng.mL-1); o PCB 153 foi detectado em 62,50% e o PCB 180, em 54,17% das amostras. Em relação aos níveis de APE, estes não apresentaram correlação significativa com as concentrações de PCBs nas amostras analisadas. Há escassez de trabalhos de análise desses compostos em amostras de soro de indivíduos humanos realizados no Brasil. Por conseguinte, realização de estudos adicionais são sugeridos para determinar os fatores causadores dessa contaminação, bem como novas investigações sobre a influência da concentração de PCBs sobre as taxas de APE nas amostras de soro de indivíduos do sexo masculino.Citas
