dosage
maximum length of time an individual can be exposed to an airborne substance before injury, illness, or death ocurs
exposure limit
quantity of a material in relation to a larger volume of gas or liquid
concentration
may describe the concentration of a gas or vapor in the air or the concentration of a specific material in a liquid or solid

short-term exposure limit
concentration that should not be exceeded during an 8 hour workday
threshold limit value - ceiling
concentration at which most people are not adversely affected
permissible exposure limit
concentrations high enough to kill or cause serious injury or illness
