Ecotoxicity testing with ‘difficult’ substances

December 21st, 2018

A reliable understanding of the aquatic hazard of a test substance is vital for risk assessment of chemicals, because assessment of both chemical hazard and risk arising from expected use rely on this in most circumstances. The use of standardised toxicity testing guidelines is... read more »

OECD Guidance for Characterising Hydrocarbon Solvents for Assessment Purposes

March 25th, 2016

The Organisation for Economic Co-operation and Development (OECD) has issued guidance on characterisation of UVCB hydrocarbon (HC) solvents.These substances range from 5-20 carbons, comprising the hydrocarbon classes of paraffins, isoalkanes (branched alkanes), naphthenes, aromatics, n-alkanes (or n-paraffins/saturated linear alkanes), branched alkanes (isoparaffins) and cycloalkanes.The... read more »

OECD improving guidelines on risk assessment and management of nanomaterials
