They are compiled and constantly reviewed under internationally coordinated programs for establishing the risk potential of existing chemicals to prevent health hazards at the working place. In Volume 8, data for the following chemicals are published: p-t-Butylbenzoic acid, Diethylene glycol monomethyl ether, 2,4-Xylidine, Thioglycolic acid 2-ethylhexyl ether, Fluorobenzene, 2-Fluorotoluene, 4-Bromofluorobenzene, Tributyl phosphate, Isobutylidenediurea, Azodicarbonamide, Tellurium diethyldithiocarbamate, Aminofen, Diethylene glycol bis(chloroformate), N-(2,4-Dimethylphenyl)-3-oxo-butyric acid amide.
