All the listed factors contribute to benzene pollution exposure. Automobile exhaust (1) contains benzene from incomplete combustion of fuel. Tobacco smoke (2) is a major source of indoor benzene exposure. Wood burning (3) is another combustion source releasing benzene. Using varnished wooden furniture (4) and products made of polyurethane (5) can off-gas benzene and other VOCs as they may contain solvents or release byproducts containing benzene over time, especially in indoor environments.<br \/>\n<\/section>\n<section id=\"pyq-key-points\">\nExposure to benzene pollution can occur through combustion sources (vehicles, smoking, burning) and off-gassing from various materials and products (solvents, paints, finishes).<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">\nBenzene is also found in crude oil and is used in the manufacture of plastics, resins, synthetic fibers, dyes, detergents, and pesticides. Industrial emissions and hazardous waste sites are other sources. Indoor sources like attached garages (from vehicles), stored fuels, glues, adhesives, paints, and cleaning products also contribute to benzene levels. Given the wide range of sources, it is plausible that all the listed factors contribute to human exposure to benzene.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following are the reasons\/factors for exposure to benzene pollution ? 1.
