Organochlorines and metals induce changes in the mitochondria-rich cells of fish gills: An integrative field study involving chemical, biochemical and morphological analyses
(Elsevier B.V., 2013-01-15)
Through integrating chemical, biochemical and morphological analyses, this study investigated the effects of multiple pollutants on the gill mitochondria-rich cells (MRCs) in two fish species, Astyanax fasciatus and Pimelodus ...
Acute crack cocaine exposure induces genetic damage in multiple organs of rats
(Springer Heidelberg, 2016)
Crack cocaine is a very toxic product derived from cocaine. The aim of this study was to evaluate genetic damage in multiple organs of rats following acute exposure to crack cocaine. A total of 20 Wistar rats were distributed ...
Environmental risk assessment of triclosan and ibuprofen in marine sediments using individual and sub-individual endpoints
(Elsevier Sci Ltd, 2018)
The guidelines for the Environmental Risk Assessment (ERA) of pharmaceuticals and personal care products (PPCP) recommend the use of standard ecotoxicity assays and the assessment of endpoints at the individual level to ...
Continuous Exposure to Microplastics Does Not Cause Physiological Effects in the Cultivated Mussel Perna perna
(Springer, 2018)
The environmental impact of microplastics is a challenging theme, especially under realistic experimental conditions. We investigated physiological responses to 0.1-1.0 mu m PVC particles intake by the mussel Perna perna ...
Biological effects of environmentally relevant concentrations of the pharmaceutical Triclosan in the marine mussel Perna perna (Linnaeus, 1758)
(Elsevier B.V., 2012-09-01)
Triclosan (5-Chloro-2-(2,4-dichlorophenoxy) phenol) is an antibacterial compound widely employed in pharmaceuticals and personal care products. Although this emerging compound has been detected in aquatic environments, ...
A Critical Comparison of Different Approaches to Sediment-Quality Assessments in the Santos Estuarine System in Brazil
(Springer, 2015-01-01)
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) ...
Occurrence of pharmaceuticals and cocaine in a Brazilian coastal zone
(Elsevier Science Bv, 2016)
The present study determined environmental concentrations of pharmaceuticals, cocaine, and the main human metabolite of cocaine in seawater sampled from a subtropical coastal zone (Santos, Brazil). The Santos Bay is located ...
Metal toxicity assessment by sentinel species of mangroves: In situ case study integrating chemical and biomarkers analyses
(Academic Press Inc Elsevier Science, 2017)
Globally, there is a lack of knowledge about tropical ecotoxicology dealing with the potential impact of metal contamination in mangrove ecosystem. This habitat is considered a nursery for several animal species, among ...
Leachate from microplastics impairs larval development in brown mussels
(Pergamon-Elsevier Science Ltd, 2016)
Microplastic debris is a pervasive type of contaminant in marine ecosystems, being considered a major threat to marine biota. One of the problems of microplastics is that they can adsorb contaminants in extremely high ...
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 ...
