Correct option is B
Burning solid waste can release a variety of harmful substances.
Microplastics (A): When larger plastic objects are burned, some fragments may degrade into microplastics.
Dioxins (C): Extremely toxic substances formed when burning plastics and other chlorinated materials.
PCBs (D): Released during the incineration of old equipment containing these compounds. These are carcinogenic and environmentally persistent.
Information Booster:
Microplastics: Often result from the breakdown of plastic materials and can contaminate air and water.
Dioxins: Highly toxic, linked to cancer, immune system damage, and hormone disruption.
PCBs: Polychlorinated biphenyls, harmful to health, and remain in the environment for long periods.
Burning plastic: Releases a mix of chemicals depending on the material composition, often contributing to air pollution.
Proper waste disposal: Critical to reduce the release of harmful substances like dioxins and PCBs.
Additional Knowledge:
CFCs (B): Widely used in refrigeration but contribute to ozone depletion. Although burning can release some, it’s not a typical result of incinerating general solid waste.
Halons (E): Used in fire suppression systems but not commonly associated with burning general waste.
