Question

what are pollutants? give examples?​

Answer 1

Answer:

A pollutant is a substance that when introduced in the atmosphere causes undesirable changes in the atmosphere.

The major pollutants are

• Particulate Matter.
• Chlorofluorocarbons.
• Carbon monoxide.

Explanation:

• Pollution is defined as the introduction of substances (or energy) into the environment that have a negative impact on living things.
• Chemical pollutants, such as particles, are not always the source of pollution (like smoke and dust). Sound, heat, and light are all forms of energy that can pollute the environment.
• Pollutants are the substances that pollute the environment.

Answer 2

A pollutant is a chemical or energy released into the environment that has unintended consequences or reduces the utility of a resource.

• By altering the development rate of plant or animal species, or by interfering with human amenities, comfort, health, or property values, a pollution can inflict long- or short-term harm.
• Some contaminants are biodegradable and will not stay in the environment for an extended period of time.
• However, some pollutants' degradation products, such as DDE and DDD generated from DDT breakdown, are harmful in and of themselves.
