Resumen
The presence of legacy contaminants in sediments
from three Marine Protected Areas (MPAs) of the
coast of S??o Paulo State was evaluated. Four sampling
surveys were conducted between 2013 and
2015 in 10 sites, distributed along the Laje de Santos
Marine and Xixova-Japui State Parks (PEMLS and
XJSP, respectively) and Central Coast Marine Protection
Area (APAMLC). Samples were analyzed
for sediment texture, total organic carbon, CaCO3,
metals (Al, Fe, Hg, Cd, Co, Cr, Cu, Ni, Pb and Zn),
aliphatic and polycyclic aromatic hydrocarbons (AH
and PAH). Sediments were generally sandy (excepting
muddy samples from APAMLC), with variable
amounts of TOC, OM and CaCO3. Most of the sediments
exhibited low to moderate concentrations of
metals, except APAMLC. Low contamination of
sediments by hydrocarbons was found but samples
from XLSP and APAMLC exhibited the highest
concentrations of biogenic AH and PAH from pyrogenic
sources. In APAMLC and PEMLS, the levels
of metals can be considered as background levels
according to geochemical indices (Igeo and EF).
In XJSP and especially in APAMLC data indicated
poor sediment quality, probably due to the effect of
anthropic activities. Funda????o de Amparo ?? Pesquisa do Estado de S??o Paulo (FAPESP) Conselho Nacional de Desenvolvimento Cient??fico e Tecnol??gico (CNPq) FAPESP: 13/15482-0 CNPq: 308649/2011-7; 311609/2014-7
