Question:
● ACGIH.
Answer:
American Conference of Governmental Industrial Hygienist
Question:
● Acute Exposure.
Answer:
An exposure to a toxic substance which occurs in a short or single time period.
Question:
● Acute Toxicity.
Answer:
Any poisonous effect produced by a single short-term exposure. The LD50 of a substance (the lethal
does at which 50% of test animals succumb to the toxicity of the chemical) is typically used as a
measure of its acute toxicity.
Question:
● Additive Effect.
Answer:
A biological response to exposure to multiple chemicals which is equal to the sum of the effects of
the individual agents.
Question:
,● Adsorption.
Answer:
The bonding of chemicals to soil particles or other surfaces.
Question:
● Aerosol.
Answer:
A solid particle or liquid droplet suspended in air. An aerosol is larger than a molecule and can be
filtered from the air.
Question:
● Antagonism.
Answer:
The situation in which two chemicals interfere with each other's actions, or one chemical interferes
with the action of the other.
Question:
● Aquifer.
Answer:
An underground bed, or layer, of earth, gravel, or porous storage that contains water.
Question:
● Asphyxiants.
Answer:
Chemicals that starve the cells of an individual from the life- giving oxygen needed to sustain
metabolism.
, Question:
● Biodegradable.
Answer:
Capable of decomposing quickly through the action of microorganisms.
Question:
● Biomagnification.
Answer:
The tendency of certain chemicals to become concentrated as they move into and up the food chain.
Question:
● Boiling Point.
Answer:
The temperature at which a liquid will start to become a gas, and boil. A chemical with a low boiling
point can boil and evaporate quickly. If a material that is flammable also has a low boiling point, a
special fire hazard exists.
Question:
● Carcinogen.
Answer:
A chemical or physical agent that encourages cells to develop cancer.
Question:
● Central Nervous System Depressants.
Answer:
Toxicants that deaden the central nervous systems (CNS), diminishing sensation.
