Lowering Limit Values for CS_2 and Other Chemicals in Workplace Air Boosts Demand for Higher Sensitivity Thermal Desorption Methods

摘要

The 3rd update to the EC Indicative Occupational Exposure Limit Value (IOELV) directive heralds further reductions in limit levels for chemicals in workplace air; limits for toxic and odorous chemicals including 2-ethoxyethanol, 2-ethoxyethyl acetate, methyl pyrrolidone, H_2S and carbon disulphide (CS_2) have all been reduced. CS_2 is of particular interest because personal exposure to airborne chemicals at work (industrial hygiene) has historically been measured using a manual solvent extraction method with CS_2 solvent.
