The origin and basis of threshold limit values

American Journal of Industrial Medicine, 1984
AbstractThe concept of establishing a “threshold limit” for contaminants of industrial air is based on the principles of establishing: (1) quantitative relationships between the magnitude and duration of exposure to an industrial substance and the nature and magnitude of the response of the worker, and (2) a limiting level of exposure to potentially ...

Corporate Influence on Threshold Limit Values

open access: yesPolicy and Practice in Health and Safety, 2005
Investigations into the historical development of specific Threshold Limit Values (TLVs) for many substances have revealed serious shortcomings in the process followed by the American Conference of Governmental Industrial Hygienists. Unpublished corporate communications were important in developing TLVs for 104 substances; for 15 of these, the TLV ...

Corporate influence on threshold limit values

American Journal of Industrial Medicine, 1988
Investigations into the historical development of specific Threshold Limit Values (TLVs) for many substances have revealed serious shortcomings in the process followed by the American Conference of Governmental Industrial Hygienists. Unpublished corporate communications were important in developing TLVs for 104 substances; for 15 of these, the TLV ...

Threshold Limit Values for 1964

Archives of Environmental Health: An International Journal, 1964
The threshold limit values refer to air-borne concentrations of substances and represent conditions under which it is believed that nearly all workers may be repeatedly exposed, day after day, without adverse effect. Because of wide variation in individual susceptibility, exposure of an occasional individual at or even below the threshold limit may not

Discussion of the Interpretation of Threshold Limit Values

American Industrial Hygiene Association Journal, 1966
Abstract In the calculation of threshold limit values for mixtures, the assumption of ideal behavior of liquid mixtures can lead to results considerably apart from actual conditions. Better results can be obtained by taking into account the activities of the components of such mixtures. The necessary equations and several examples are presented.

But they are not thresholds: A critical analysis of the documentation of threshold limit values

American Journal of Industrial Medicine, 1990
AbstractThreshold Limit Values (TLVs) represent conditions under which the TLV Committee of the American Conference of Governmental Industrial Hygienists (ACGIH) believes that nearly all workers may be repeatedly exposed without adverse effect. A detailed research was made of the references in the 1976 Documentation to data on “industrial experience ...
