Final answer:
Air contaminants hazards for CAC-A can include toxic pollutants, radionuclides, and polycyclic aromatic hydrocarbons (PAH). It is important to be aware of these hazards and take measures to reduce exposure to these contaminants.
Step-by-step explanation:
Air contaminants hazards for CAC-A can include toxic pollutants, radionuclides, polycyclic aromatic hydrocarbons (PAH), and various chemicals found in the environment. Examples of toxic air pollutants include benzene, perchloroethylene, methylene chloride, dioxin, asbestos, toluene, and metals such as cadmium, mercury, chromium, and lead compounds. Additionally, the accumulation of radionuclides and PAH in the air can pose health risks. It is important to be aware of these hazards and take measures to reduce exposure to these contaminants.
