What is pollution and pollutants?

Pollution is the contamination of air, water, and soil by the substances which adverse effect on human beings, animals, and plants of our environment. The substances or molecules which polluted our environment like water soil and air are called pollutants. Therefore pollutants are the substances that present with air, water and soil make them polluted and have an adverse effect on living and non-living things in environmental chemistry.

Types of Pollutants

Pollutants that polluted our environment classified as gaseous, liquid, solid, and pollutants without weight.

  • Gaseous Pollutants: Greenhouse gases like carbon dioxide, methane, sulfur dioxide, nitrogen dioxide are the major pollutants of our earth’s atmosphere. sulfur dioxide and nitrogen dioxide also cause acid rain which increases the pH of the soil.
  • Liquid Pollutants: Liquid wastage included sewage wastes and industrial wastage. Hence these wattages enter into rever and affect aquatic life and self-purification of water disturbed.
  • Solid Pollutants: The solid pollutants include ashes, dead animals, wastage sludges, chemicals, paints, sand, pesticides, insecticides, manures, crop residue, etc. The solid substances are two types like biodegradable and non-biodegradable substances.
  • Pollutants without weight: The radioactivity, specific heat, and noise are the pollutants without weight. All these are uses for the energy generation process.  The pollution caused by these substances termed as radioactive, thermal, and noise or sound pollution respectively.

Types of Pollution

There are various types of pollution that cause us to change the face of our earth. Therefore quality living changes and new issues have arisen that gradually impact our health and our environment. In these articles of learning chemistry, we discuss important types of pollution that affect our health or environment.

Air, Water and Industrial pollution

Air polluted by poisonous gases like CO, NO, NO2, SO3, O3, etc, and unburnt hydrocarbon, chemical elements, etc. Therefore, air contains harmful gases, dust, smoke, etc causes for air pollution. When insoluble solid particles, soluble salts, sewage, garbage, and low-level radioactive substances, industrial wastages, algae, bacteria, etc go into the water, water gets polluted, These types of pollution are called water pollution.

Industrial Pollutants

The wastage discharges by industries make water, air, and biosphere polluted. The industrial wastage contains chemical elements like Hg, Na, Cd, As, Pb, Ca, etc and organic compounds like acid, alkaline, alcohol, etc. Therefore, these wastages threw into lakes and rivers, and the water of lakes and rivers polluted. Carbon dioxide from industrial burning causes global warming. While sulfur dioxide and nitrogen dioxide causes sulfuric acid and nitric acid rain. Nuclear power plants also emitted harmful rays like alpha, beta and gamma rays to our earth atmosphere impact our health.
