Burning waste that contains polyvinyl chloride (PVC) in an incinerator is hazardous mainly because it can release

Amethane and hydrogen
Bozone and helium
Chydrogen chloride and dioxins
Donly carbon dioxide and water

Answer: C

PVC contains chlorine. On incineration it gives HCl gas and, under poor combustion conditions, toxic chlorinated organics such as dioxins. Incineration of chlorine-free organics gives mostly

CO X_{2}

and water.
