ACGIH - American Conference of Governmental Industrial Hygienists http://www.acgih.org/ is an organization that is responsible for creating TLV exposure guidelines. Atmospheric Hazards - Any substance that people introduce into the atmosphere that has damaging effects on living things and the environment is considered air pollution. Air pollution occurs when harmful substances including particulates and biological molecules are introduced into Earth's atmosphere. It may cause diseases, allergies or death in humans; it may also cause harm to other living organisms such as animals and food crops, and may damage the natural or built environment.

A-weighted decibels (dBA) - The relative measure of loudness of sounds in the air that are perceived by the human ear. The sound level (dBA) created by a task over an eight-hour work day. See the following table for permissible noise exposures under OSHA 29 CFR 1910.195. here

Human Effects - A human health risk assessment is the process to estimate the nature and probability of adverse health effects in humans who may be exposed to chemicals in contaminated environmental media, now or in the future.

- Acute: Caused by the initial exposure of a hazardous chemical on a human or animal body. When a hazardous material's acute health effect is listed, the effects are generally severe and dangerous adverse effects, but subside after the exposure stops.
