The volumes of this series present almost 300 indispensable toxicological evaluation documents on important occupational toxicants and carcinogens. They describe the toxicological database which determines the level of a MAK value (Maximum Concentrations at the Workplace). Each evaluation document is written to a standard format and includes sections about toxic effects, modes of action, effects in man, effects on animals, genotoxicity and carcinogenicity, manifesto.

The accumulated expertise of the Commission's toxicologists and occupational physicians makes their reviews inevitable for all involved in occupational health and safety. Volume 9 contains 29 new compounds, half of them metal-working fluid components.
