Abstract

Toxic air
pollutants also known as hazardous air pollutants that cause cancer or other
serious health effects, such as reproductive effects or birth defects, or
adverse environmental effects. Some can even cause death or serious injury if
accidentally released in large amounts. Examples of air toxics include;
benzene, perchloroethylene dioxin, methylene chloride, asbestos, toluene, and
metals such as cadmium, mercury, chromium, and lead compounds which is emitted
from number of industries.

Many air
pollutants remain in the environment for long periods of time and are carried
by the winds hundreds of miles from their origin. Millions of people live in
areas where urban smog, very small particles, and toxic pollutants pose serious
health concerns. People exposed to high enough levels of certain air pollutants
may experience burning in their eyes, an irritated throat, or breathing
difficulties. Long-term exposure to air pollution can cause cancer and
long-term damage to the immune, neurological, reproductive, and respiratory
systems. In extreme cases, it can even cause death.

Environmental
risk assessment described as the characterization of the potential adverse
health effects of human exposures to environmental hazards. Characterizing risk
involves integrating information on hazard, dose-response, and exposure.

There are main
two steps of the risk assessment process: Hazard identification and
Dose-Response Assessment. There are many programs that make identify human
exposure pathways and estimate the amount of human exposure under different
exposure scenarios and many toxic tools to asses environmental air toxic
substances. Several databases, models and act are used to find health and
safety information.
