Ecotoxicology of Stable Pollutants in African Marine Ecosystems

Molluscs (particularly bivalves) and fish are usually proposed as good bioindicators for environmental contamination of marine ecosystems. Different steps can be recognized when assessing such contamination. The first approach consists of comparing stable residue concentrations determined in various environments or different periods. In this chapter, this is illustrated for heavy metals in biva...

Validation of Reference Genes for RT-qPCR in Marine Bivalve Ecotoxicology: Systematic Review and Case Study

Reverse transcription real-time quantitative PCR (RT-qPCR) is the predominant method of choice for the quantification of mRNA transcripts of a selected gene of interest. Here reference genes are commonly used to normalize non-biological variation in mRNA levels and their appropriate selection is therefore essential for the accurate interpretation the collected data. In recent years the use of m...

Arsenic in marine sediments from French Mediterranean ports: geochemical partitioning, bioavailability and ecotoxicology.

This work investigates arsenic mobility, bioavailability and toxicity in marine port sediments using chemical sequential extraction and laboratory toxicity tests. Sediment samples were collected from two different Mediterranean ports, one highly polluted with arsenic and other inorganic and organic pollutants (Estaque port (EST)), and the other one, less polluted, with a low arsenic content (Sa...
