For over 85 years, ACGIH has been respected for its dedication to the industrial hygiene and occupational and environmental health and safety communities. We have grown and expanded without losing sight of our original goal – to encourage the interchange of experience among industrial hygiene workers and to collect and make accessible such information and data as might be of aid to them in the proper fulfillment of their duties.

This scientific information and data are provided to subscribers and others in the industry through ACGIH and AIHA’s monthly peer-reviewed journal, the Journal of Occupational and Environmental Hygiene (JOEH), and our professional conferences and seminars, as well as through our vast list of technical and scientific publications, including the renowned TLVs and BEIs book.
