the answer is
Explanation:
The threshold limit value (TLV) is usually expressed in units of parts per million (ppm) - i.e., the parts of vapor (gas) per million parts of contaminated air by volume at 25 ° C (77 ° F) and atmospheric pressure. For a chemical that forms a fine mist or dust, the concentration is given in milligrams per cubic meter (mg/m3). The TLV is defined as the concentration of the substance in air that can be breathed for five consecutive eight-hour workdays (40-hour work week) by most people without adverse effect. (This definition is given by American Conference of Governmental Industrial Hygienists, “Threshold Limit Values for Substance in Workroom Air, Adopted by ACGIH for 1972”).
