Question

What is air and water pollution?

Answer 1

Step 1: Air pollution

1. Air pollution is defined as any physical, chemical, or biological change in the air.
2. Air pollution from harmful gases, dust, and smoke has serious consequences on flora and fauna. The air quality index (AQI) is commonly used to assess air quality. Alternatively, particulate matter (PM) can be used to assess air quality.${\mathrm{PM}}_{2.5}$ is a tiny particle with a diameter of 2.5 microns.
3. When there are high amounts of ${\mathrm{PM}}_{2.5}$ particles in the environment, it can generate haze, which is a symptom of poor air quality.

Step 2: Water pollution

1. The contamination of bodies of water usually due to human activities is referred to as water pollution.
2. Water pollution occurs when industrial and agricultural effluents contaminate rivers, lakes, oceans, groundwater, aquifers, etc.
3. Water quality may be determined in a number of ways. Coloured or chromophoric dissolved organic matter (CDOM), total dissolved solids (TDS) monitoring, conductivity, salinity, and measuring dissolved oxygen levels are some of the most prevalent ways to determine the quality of water.
