Resumo
In this study, the quality of sediments from three
Marine Protected Areas (MPAs) located on the coast
of São Paulo (Laje de Santos Marine State Park -
PEMLS; Xixova-Japui State Park - XJSP; and Central
Coast Marine Protection Area - APAMLC) was
assessed. Four sampling surveys were conducted
(September/October 2013; January 2014; July 2014;
January 2015). Sediment samples were collected
at10 sites, distributed along the 3 MPAs. Samples
were analyzed for sediment texture, total organic
carbon, CaCO3, metals, aliphatic and polycyclic
aromatic hydrocarbons, and for whole-sediment and
sediment-water interface toxicities. Principal component
analysis (PCA) was used to integrate data.
Most of the sediments exhibited low concentrations
of chemicals, with the exception of those from P2
(APAMLC) where moderate levels of contaminants
were detected. Sediments from P7 and P9 (PEMLS)
occasionally showed signs of petroleum hydrocarbons.
The other sediments showed no relevant
contamination but presented variable toxicity, especially those of bioclastic composition. The PCA
indicated a contribution of the sediment properties
to the toxicities, especially the CaCO3. In bioclastic
sediments, toxicity might be due to physical causes
by or any indirect factor such as the presence of
ammonia. It was concluded that both natural and
anthropic factors are causing toxicity in sediments
from the MPAs studied.
