[Maximum immission concentrations and maximum allowable concentrations and their significance in the evaluation of indoor conditions].

Schriftenreihe des Vereins fur Wasser-, Boden- und Lufthygiene, 1983
In the work-place environment MAK values (maximum allowable workplace concentrations) haven been fixed as time-integrated averages relatively early in order to avoid adverse health effects to workers exposed to air pollution during their working shift. Similarly, MIK values (maximum immission concentrations have been set up to protect the health of the

Revisions to Spacecraft Maximum Allowable Concentrations for 2-Butanone

Aerospace Medicine and Human Performance
INTRODUCTION: At high concentrations 2-butanone is an irritant that may cause central nervous system effects. In 1996, NASA established spacecraft maximum allowable concentrations (SMACs) for short-duration, off-nominal scenarios at 50 ppm based on human exposure data from the 1940s.

Studies on the toxicity and maximum allowable concentration of chloroform.

Biomedical and environmental sciences : BES, 1993
Chloroform has obvious hepato-, nephro-toxicity and carcinogenicity. In order to get necessary data for recommendation of maximum allowable concentration of chloroform in workplace, a series of studies were carried out. The results showed that exposed workers mainly distributed in the industries of perspex processing, production of refrigerants, drugs ...

Basic concepts for maximum allowable concentrations of toxic substances

Pure and Applied Chemistry, 1961
Exact definition of basic concepts and terms is of paramount importance to the question of maximal allowable concentrations of toxic substances in industrial atmospheres. The differences existing in various countries are often due to differences in the interpretation of basic concepts.
