Benzo(a)pireno, carbamato de etila e metanol em cachaças [PDF]
Química Nova, 2010 The objective of this work was to evaluate the presence of benzo(a)pyrene (BaP), ethyl carbamate (EC) and methanol in 61 samples of cachaça. The quantification of BaP was carried out using HPLC with fluorescence detection, EC concentrations was determined by GC/MS and that of methanol, by GC/FID.

Avaliação do destino e bioacumulação de benzo(a)pireno através de simulação computacional [PDF]
Química Nova, 2008 The objective of this work was to evaluate the environmental distribution of benzo(a)pirene, a polycyclic aromatic hydrocarbon, by the EQC model. The modeling of the contaminant distribution was accomplished by means of the fugacity model applied to a hypothetical scenario constituted by air, water, soil and sediment.

Hidrocarbonetos policíclicos aromáticos - benzo(a)pireno: uma revisão
Revista do Instituto Adolfo Lutz, 2008 Os hidrocarbonetos policíclicos aromáticos (HPAs) constituem um grupo de compostos contendo dois ou mais anéis aromáticos condensados. Estes compostos são formados, principalmente, pela combustão incompleta da matéria orgânica. Os estudos em cobaias têm demonstrado que muito desses compostos, incluindo o benzo(a)pireno (BaP), são carcinogênicos e ...
