Question:

How does the burning of synthetic polymers such as plastic pollute the environment?

Options:

By releasing smoke and toxic gases

By releasing water vapour and haze

By forming smog and rain

By releasing water vapour and smoke

Correct Answer:

By releasing smoke and toxic gases

Explanation:

The correct answer is option 1. By releasing smoke and toxic gases.

The burning of synthetic polymers such as plastic pollutes the environment primarily by Releasing smoke and toxic gases.

1. Smoke Emission:  Burning plastic releases thick, black smoke composed of particulate matter. This smoke can contribute to air pollution and reduce air quality.

2. Toxic Gas Emission:

Synthetic polymers often contain additives, colorants, and stabilizers that, when burned, release toxic gases such as carbon monoxide, hydrogen chloride, dioxins, and furans. These pollutants can harm human health and the environment.

3. Contribution to Global Warming:

The combustion of synthetic polymers releases greenhouse gases like carbon dioxide, contributing to global warming and climate change.

4. Formation of Secondary Pollutants:
The incomplete combustion of plastics can lead to the formation of secondary pollutants such as volatile organic compounds (VOCs) and other hazardous substances.

5. Environmental Impact:

The pollutants released during the burning of plastics can have detrimental effects on ecosystems, soil, and water quality. They can also contribute to the acidification of rain.

6. Smog Formation:

Smoke and pollutants from burning plastics can contribute to the formation of smog, affecting visibility and causing respiratory issues.

It is important to note that burning synthetic polymers is not an environmentally friendly disposal method. Recycling, reducing plastic use, and proper waste management are more sustainable approaches to mitigate the environmental impact of plastics.
