to determine PAHs in in upper Gulf off the mouth of the Chao Phraya River,
paid to the Mundaú Lagoon. At Maceió, an important antropogenic
event of PAH emission are the sugarcane burning activities. The
analysis of mussel was performed for different sizes to understand
their status of contamination. In addition, considering that sugarcane
burning is a potential source of PAHs in the study area, PAH ratios
were calculated to determine the main anthropogenic sources. The
study of PAH in sugarcane monoculture areas is very important
because such burning events cause environmental impacts on the
human, vegetal and animal health.
