Cobalt is a brittle, hard metal, resembling iron and nickel in appearance. It has a metallic permeability of about two-thirds that of iron. The transformation is slnggish and accounts in part for the wide variation in reported data on physical properties of cobalt. Exposure to cobalt (metal fumes and dust) should be limited to 0.05 mg/m (8-hour time-weighted average in a 40-hour week).

Lead is present in the work atmosphere as fumes, mists (e.g., produced by spray painting) and dust. Inhalation of lead fumes or of fine lead particles is the most important route of absorption in the working atmosphere. Lead poisoning is one of the most common occupational diseases, especially when prevention measures are not established (IPCS 1995). Further metals and their compounds that, among others, are known to cause chronic occupational intoxications at the workplace are antimony, arsenic, beryllium, cadmium, chromium, cobalt, manganese, mercury, nickel, thallium, and vanadium (DEG 1972-2001).
