Genotoxic effects of CdS quantum dots and Ag2S nanoparticles in fish cell lines (RTG-2)
No full textThe increasing use of nanotechnologies will lead to significant releases of engineered nanoparticles into the aquatic environment, where their impact is still poorly characterized. In the present paper, the genotoxic and cytotoxic properties of CdS quantum dots (QDs) and silver sulphide (Ag2S) coated with methyl polyethylene glycol (M-PEG) were investigated in a rainbow trout cell line (RTG-2). The results showed that CdS QDs were highly cytotoxic at high concentrations (10 and 50mug/ml), and exhibited a concentration-dependent genotoxicity in the sub-toxic range (0.01-1mug/ml) after 24h exposure. Ag2S showed neither genotoxic nor cytotoxic effects

Genotoxic effects of Ag2S and CdS nanoparticles in blue mussel (Mytilus edulis) haemocytes
No full textThe use of functionalised metal sulphide nanoparticles (NPs) for nanoremediation and biomedical application is rapidly increasing, which could lead to significant inputs into the marine environment. The potential impact of some NPs on marine organisms is still poorly understood. In the present paper the genotoxic potential of Ag2S and CdS NPs on Mytilus edulis haemocytes was assessed. MPEG-SH (thiol-terminated methyl polyethylene glycol), was used as capping agent to avoid NPs agglomeration. TEM analysis showed that the Ag2S NPs size was 13 +/- 7nm, whereas CdS quantum dots had an average diameter of 4 +/- 1nm. DNA integrity was evaluated by Comet assay following exposure to increasing concentration series (0.01-10 mg/L). Both silver and cadmium NPs showed genotoxic effects at the highest dose. MPEG-SH was also found to exert a weak genotoxic activity, suggesting that at least part of the genotoxic potential of functionalised NPs on mussel cells might be attributable to the capping agent. These results confirm the genotoxic potential of Ag2S NPs for mussel cells and demonstrated, for the first time, that CdS NPs is genotoxic in a marine organism
DNA damage in eelpout (Zoarces viviparus) from Goteborg harbour
No full textThe relationship between DNA damage and the exposure of marine organisms to environmental contaminants was
examined in the Goteborg harbour area. This research is part of a wider ecotoxicological study planned to evaluate the biological
impact of chemical contamination in the River Gota estuary, following a bunker oil (10-100 tonnes) spill occurred in June 2003.
Here we present data on the DNA strand breaks derived using the comet assay and the presence of apoptotic cells using the
diffusion assay in nucleated erythrocytes of the eelpout (Zoarces viviparus) from the study area and at a clean reference site.
Polycyclic aromatic hydrocarbon metabolites were also analyzed in the bile of exposed fish. The results showed a high level of
damaged DNA, paralleled by a peak in bile PAH metabolites, in fish from the most impacted site, 3 weeks after the oil spill. A
significant recovery was observed in specimens from the spill site, 5 months later, but not in fish caught in the middle part of
Goteborg harbour, which is chronically subjected to heavy chemical pollution. The levels of apoptic cells did not show any marked
variations, but a significant recovery was observed in fish from the oil impacted site 5 months after the spill

A Tripartite Post-Recession Rebalancing
No full textIn this latest Advance & Rutgers Report, entitled “A Tripartite Post-Recession Rebalancing,” Dean James W. Hughes and Professor Joseph J. Seneca deliver an incisive assessment of the current market conditions and obstacles in the path of our economic recovery. They offer a statistical cautionary tale that the private and public sector need to hear and acknowledge in order for the economy to make continued progress.This report was published as Issue Paper Number 7, November 2011, in Advance & Rutgers Report
