Maximum Allowable Concentrations of Mixtures

American Industrial Hygiene Association Journal, 1962
Abstract In evaluating exposure to mixtures of toxic substances, conclusions are usually based solely on the concentration of the most toxic or major component. This procedure is in general logical only when the different substances act independently.

Spacecraft Maximum Allowable Concentrations for Manganese Compounds in Mars Dust

Aerospace Medicine and Human Performance, 2019
INTRODUCTION: Exposure to excess manganese (Mn) can cause multiple toxicological outcomes in humans, most notably neurotoxicity. Ample epidemiological evidence suggests that chronic, low-level exposure causes subclinical cognitive effects. Because NASA astronauts will be exposed to Mars regolith, Spacecraft Maximum Allowable Concentrations (SMACs ...

Revisions to Spacecraft Maximum Allowable Concentrations for Acetaldehyde

Aerospace Medicine and Human Performance
INTRODUCTION: Spaceflight Maximum Allowable Concentrations (SMACs) were previously developed for acetaldehyde in 1994. Acetaldehyde is commonly detected at low levels on the International Space Station, and at higher concentrations it might be expected to cause respiratory and eye irritation.

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.

[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
