Shell alterations in limpets as putative biomarkers for multi-impacted coastal areas
(Elsevier Sci Ltd, 2017)
During the last years, shell alterations in gastropods have been proposed as tools to be used in monitoring programs. However, no studies were so far performed investigating the relationships among shell parameters and ...
A Critical Comparison of Different Approaches to Sediment-Quality Assessments in the Santos Estuarine System in Brazil
This study focuses on the discussion of different lines of evidence (LoEs) applied to a sediment-quality assessment that considered the following: chemical concentrations of metals; polycyclic aromatic hydrocarbons (PAHs) ...
Effects of harbor activities on sediment quality in a semi-arid region in Brazil
(Academic Press Inc Elsevier Science, 2017)
Tropical marine environments are rich in biodiversity and the presence of harbor activities in these areas can harm the coastal ecosystems. In this study, we assessed sediment quality of two harbors from a tropical region ...
Integrated quality assessment of sediments from harbour areas in Santos-Sao Vicente Estuarine System, Southern Brazil
(Elsevier B.V., 2013-09-20)
Santos-Sao Vicente Estuarine System is a highly populated coastal zone in Brazil and where it is located the major port of Latin America. Historically, port activities, industrial and domestic effluents discharges have ...
The application of biochemical responses to assess environmental quality of tropical estuaries: field surveys
(Royal Soc Chemistry, 2012-10-01)
A battery of biomarkers of exposure (EROD, DBF, GST and GPx) and effect (lipid peroxidation and DNA damage - strand breaks) were analyzed in gill tissues from caged and native oysters Crassostrea rhizophorae exposed to two ...
A tiered approach to assess effects of diclofenac on the brown mussel Perna perna: A contribution to characterize the hazard
(Pergamon-Elsevier Science Ltd, 2018)
Pharmaceutical discharges into the aquatic ecosystem are of environmental concern and sewage treatment plants (STPs) have been pointed out as the major source of these compounds to coastal zones, where oceanic disposal of ...
Metals and arsenic in fish from a Ramsar site under past and present human pressures: Consumption risk factors to the local population
(Elsevier Science Bv, 2018)
The risk of metals and As in seafood for traditional populations living in a Marine Protected Areas (MPA) is seldom assessed, although the risk of human exposure to contaminants is one of the indicators associated with the ...
Exposure to crack cocaine causes adverse effects on marine mussels Perna perna
(Pergamon-Elsevier Science Ltd, 2017)
Our study aimed to evaluate crack cocaine effects in different life stages of the marine mussel Perna perm. For this purpose, fertilization rate, embryo-larval development, lysosomal membrane stability and DNA strand breaks ...
Using large amounts of firefighting foams releases per- and polyfluoroalkyl substances (PFAS) into estuarine environments: A baseline study in Latin America
We analyzed per- and polyfluoroalkyl substances (PFAS) in aqueous film-forming foams (AFFFs) used to extinguish a major fire in a petrochemical terminal from the Port of Santos (Brazil). Eight AFFFs from seven known ...
