“…Japenga and co-workers reported in 1988 sediment concentrations of organic micropollutants in the Rio de Janeiro coastal area ( Japenga et al, 1988). Their OC and PAH values are within the same order of magnitude of the ones reported here.…”

The paper is a contribution for the knowledge upon concentrations and fate of different kinds of organic micropollutants in Tropical River system from a very industrialized region in Brazil. The presented data was obtained during three years of an International Research Project between Brazilian and Dutch institutions. The sediments were sampled at the Paraiba do Sul-Guandu river watershed, the most important watercourse of Rio de Janeiro state, where up 90% of the population depends on its water for domestic uses. After extraction with non-polar solvents in a hot sohxlet device and clean up using chromatographic columns, three classes of organic micropollutants were analyzed: organochlorine insecticides (OCs), polychlorinated biphenyls (PCBs) and polynuclear aromatic hydrocarbons (PAHs). The organochlorines, including the PCBs were scarcely present in the collected samples probably reflecting the restrictions of use of this class of compounds in the Brazilian market. However, the PAHs levels were high at the vicinity of a huge steelworks located in the city of Volta Redonda. This contamination is probably due to the massive use of coal in the above-cited metallurgical plant.

“…34 The values found for Cd are within the range detected by Leitão, 35 while the Zn values were greater than those reported by the same author, in reference to superficial sediments in Marambaia Sound. The Cu concentrations are somewhat less than those found by Rodrigues 36 in superficial sediments of the mouth of the São Francisco channel, most likely due to the distance of the principal sources Cu, located at the Northeast of Sepetiba Bay.…”

“…PCB contamination is evident from major urban areas located on estuaries. Mean levels of 15.7 ± 19.2 ng/g were reported in sediment from Rio de La Plata in Argentina and up to 25 ng/g in Brazil (Colombo et al, 1990;Japenga et al, 1988). These levels are generally lower than the sediment values reported by Iwata et al (1994) for urban Australian areas.…”
