| Abstract | The diagnosis of polluting substances, with both organic and inorganic characteristics, at superficial waters and bottom sediments is an important tool for the assessment of reservoirs pollution. Water bodies and contaminated sediments are important subjects for environmental researches, involving governmental agencies and legislators. Due to its chemical stability and endurance, the polycyclic aromatic hydrocarbons (PAHs) contaminant class and trace elements, are the major contributors for the depletion of superficial waters quality. In this research, gross water and bottom sediments samples were collected in Parque Natural do Pedroso’s reservoir in Santo André, SP, in 2008 before the construction of the Mario Covas ring road, in 2010 during the construction and in 2011 after the construction had been concluded and 2014 after over 3 years of use. For analysis, the reversed-phase liquid chromatography with UV/vis for PAHs determination was used as technique. Optical Emission Spectrometry with Argon Plasma (ICP-OES) and Atomic Absorption Spectrometry-AAS were used for evaluation of metals. The PAHs’ behavior in the five collection points and at different periods is very similar, and this homogeneity suggests that these compounds have the same emission source. For the studied PAHs, significant results were found in 2011’s collection, a period in which the beltway had been working for one year and a half, at its full capacity, with an expressive traffic flow increase of smaller, medium-sized and heavy vehicles next to |
