Objective Question & Answer

Carbon monoxide - Asphyxia: Carbon monoxide CO binds strongly with blood hemoglobin to form carboxyhemoglobin.

This prevents oxygen transportation in the body, leading to tissue hypoxia and chemical asphyxia (suffocation).

Halogenated Solvents - Attack the liver: Halogenated hydrocarbon solvents (such as carbon tetrachloride or chloroform)

undergo metabolic activation in the body, releasing toxic free radicals that primarily target and cause severe damage to

the liver (hepatotoxicity).

Hydrocarbons - Cause cancer: Many ambient hydrocarbons, particularly Polycyclic Aromatic Hydrocarbons (PAHs) like

benzene or benzo[a] pyrene, are well-documented carcinogens that mutate DNA and lead to cancer.
