Spaceflight Maximum Allowable Concentrations for Ethyl Acetate

Aerospace Medicine and Human Performance, 2023
INTRODUCTION: Ethyl acetate is a simple organic compound that occurs naturally and is used industrially as a solvent. It has been detected in the ISS atmosphere and is known to off-gas from building materials. As NASA astronauts have been and will be exposed to ethyl acetate during space missions, Spaceflight Maximum Allowable Concentrations (SMACs ...

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 ...

On the so-called "maximum allowable biological concentrations"

Pure and Applied Chemistry, 1961
The maximum allowable biological concentration of a toxic substance is the highest concentration which can be found in a biological medium without damage to health. The biological materials rna y be examined for: (a) the toxic substance itself; (b) a product of the metabolism of the toxic substance in the body; (c) a substance derived from the ...
