In situ remediation of contaminated marinesediment: an overview.

Sediment tends to accumulate inorganic and persistent hydrophobic organic contaminants representing one of the main sinks and sources of pollution. Generally, contaminated sediment poses medium- and long-term risks to humans and ecosystem health; dredging activities or natural resuspension phenomena (i.e.

Potential effects of TiO nanoparticles and TiCl in saltwater to Phaeodactylum tricornutum and Artemia franciscana.

Nanosized titanium dioxide (nTiO) is widespread in many commercial products and several authors investigated its ecotoxicity effects focusing mainly on freshwater environments. Data on saltwater species are still lacking or present contradicting results. We compared for the first time the toxicity of TiCl and nTiO considering standard toxicity tests with microalgae Phaeodactylum tricornutum (growth inhibition test, 1.
