Survey of petroleum aromatic hydrocarbons in the São Sebastião Channel, SP, Bra...

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 fou...

Determination of ΣDDT and PCBs in the seawater by pre-concentration method...

A pre-concenvration method for extracting organochlorines from seawater was employed to analyse ΣDDTs and PCBs. The sampling device and the conditions for optimal adsortion performance are described. Recovery tests with spiked solutions were made before applying the method on real samples. Working up of the samples prior to gas chromatographic analysis, precautions and advantages of the procedure are also ...
