to determine PAHs in in upper Gulf off the mouth of the Chao Phraya River,
Source identification was evaluated by PAH
isomeric ratios and supplied by aliphatic hydrocarbon parameters and
the presence of petroleum biomarkers. The individual mussels were
collected in Mundaú Lagoon, Maceió City, state of Alagoas, Brazil. The
impact of the sugarcane burning in the estuarine ecosystems and on
human consumers is being studied; particular attention should be
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.
