Core Books/NCERT
Areas of heavy traffic, gas stations, and areas near industrial sources may also have higher air levels. Cigarette smoking and secondhand smoke including wood burning are important sources of exposure to benzene. Cigarette smoke accounts for about half of the exposure to benzene in the United States. Varnished wooden furniture prevents the scope of benzene pollution. During fires, polyurethane foams burn rapidly and produce dense smoke, toxic gases and intense heat. However the production of benzene is not a exposing factor in these fires Therefore, the correct answer is (a)
