New: Reprotoxicology focus group

eco-immunosafety

International Congress of Immunology (Milano, Italy, August 22-27, 2013): the workshop "Immunopharmacology" led by me and Giselle Penton-Rol has included three oral presentation on immunosafety. ◦ Boraschi, D., and G. Penton-Rol. 2013. Perspectives in immunopharmacology: the future

In the activities of NANoREG, the protocols for testing immunosafety are being defined and included among the important issues both in in vivo and in vitro safety testing (WP4 and WP5).

Very active network of major genotoxicity groups that includes many labs, EC countries

Meeting in the OECD nanotoxicology workshop Genotoxicity in Ottawa, November 2013

(Hannu Norppa and Shareen Doak had presentations).

New cell transformation assay for genotoxic as well as nongenotoxic nanomaterials

The focus of the group is towards High throughput methods for nanotoxicology (nanogenotoxicology). New COST action proposal both in in vivo and in vitro safety testing (WP4 and WP5).

Very active network

2° MANET (Marine Ecotoxicology) International workshop be probably mid November

Review

Aiming new workshop SOT2015

Soil pH is a major factor governing metal-based ENM fate and effects in soils, and the effect of pH seems to overrule that of other factors like organic matter content.

In addition to pH, ionic strength and/or salinity are a major factor affecting ENM fate and effects to aquatic organisms.

The presence of a coating may increase toxicity of metal-based ENMs but may reduce their dissolution rate.

Long-term equilibration of metal-based ENMs in soils may lead to a slow dissolution of metal ions over time, which may still continue after 1 year; this process is concentration and pH dependent.

Long-term equilibration may decrease toxicity of ZnO ENMs, but may lead to increased toxicity of Ag ENMs.

Metal ENMs and ions have different uptake routes and toxicokinetics leading to different internal levels of metals as well as different toxicodynamics.
