The region of exposure to lead, asbestos, radon, and PBDEs.
Answer to Problem 3TYC
The harmful chemical compounds such as lead, asbestos, radon, and PBDEs are indoor hazards that cause detrimental effects on human health.
Explanation of Solution
Toxicity is defined as the degree at which a chemical substance harms humans and animals. Toxic substance occurs either naturally in nature or is synthesized artificially in laboratories. It causes adverse effects on human health and disrupts various physiological and physical functions of cell.
The region of exposure to harmful chemicals is described as below:
Radon is a radioactive gas which is released from cigarette smoke and is one of the most harmful indoor hazards that causes lung cancer.
Asbestos are chemicals that are used as insulation in walls and other products and affect the health when inhaled.
Lead poisoning is caused from water pipes or lead paints that are used to paint walls. It causes serious cognitive problems, behavioral abnormalities, damage to vital organs and leads to death.
PBDEs are polybrominated diphenyl ethers. They are used as fire retardants in computers, televisions, plastics, and furniture. These compounds evaporate at very slow rate and act as endocrine disruptors. It also causes cancer.
