Popis: | Several polycyclic aromatic hydrocarbons are considered carcinogenic and mutagenic. 16 of these compounds are listed as priority control pollutants by the USEPA. The present study aimed at the evaluation of the presence of PAHs in sediments of an urban stream by GC-MS. The study area was located in Indaiatuba-Sao Paulo-Brazil, and supplies to approximately 40,000 people of a region with limited availability of water. Therefore, this water body flowing in the urban region represents a case study of the potential risk in using this water for drinking. The results show that, in general, the sampling site near the intake of the water treatment plant for human consumption had the highest concentration of total PAHs (247.7μg kg−1). This is the site that presents more contact with urban pollution and surface runoff from the streets. The PAHs composition pattern by ring number presented a higher proportion of hydrocarbons of 4- and 5-rings, and showed a tendency, in the majority of the samples, of predominance of... |
