Burning of solid waste, such as cans, batteries, plastic etc., generates which of the following? Choose the correct answer from the options given below.

1.Microplastics
2.Chlorofluorocarbons (CFCs)
3.Dioxins
4.Polychlorinated biphenyls (PCBs)
5.Halons
A1, 2, 3 and 4 only
B1, 3 and 4 only ✓ Correct
C2, 4 and 5 only
D2, 3 and 5 only
Correct answer: (B) 1, 3 and 4 only
Explanation

Burning mixed solid waste of cans, batteries and plastic releases the tiny plastic residues, dioxins and PCBs listed as the correct set.

Statement 1 holds because incomplete combustion of plastic sheds fine plastic residues into ash and air.

Statement 3 holds because dioxins form when chlorine-bearing plastics burn at moderate temperatures.

Statement 4 holds because polychlorinated biphenyls are released and reformed during such uncontrolled burning.

Statement 2 fails because chlorofluorocarbons are manufactured refrigerants, not products of combustion.

Statement 5 fails because halons are fire-suppressant chemicals and are not generated by burning waste.
