Abstract

A survey of the petroleum aromatic hydrocarbons levels on the surface waters of the São Sebastião Channel, São Paulo, Brazil is presented. The survey was done in order to assess the influence of the biggest maritime oil terminal of Brazil on the petroleum hydrocarbons levels of the area. Fourty four samples taken from 1 m depth were analysed by fluorescence spectroscopy. The highest level, 45.29 µg.1-1, was found on the side of an anchored tanker and the lowest detectable level was 0.19 µg.1-1.<br>Foi realizado um levantamento dos níveis de hidrocarbonetos do petróleo em águas superficiais do Canal de São Sebastião, São Paulo, Brasil. Esse levantamento foi feito para avaliar a influência de hidrocarbonetos do petróleo do maior terminal de óleo do país. Foram coletadas 44 amostras a 1 m de profundidade, extraídas em n-hexano e analisadas por espectrofluorescência. O ponto de maior concentração, 45,29 µg.1-1, foi coletado ao lado de um navio petroleiro ancorado na região, e o menor valor detectado foi de 0.19 µg.1-1 proveniente da parte sul do Canal.
