Question

Given below are scenes, list the main pollutants for each and identify which type of pollution each causes. Give reasons to support your answers.

Answer 1

1. Scene a (Vehicles Emitting Smoke):
   • Main Pollutants: The primary pollutants in this scene are carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter (PM).
   • Type of Pollution: Air Pollution.
   • Reason: The smoke and exhaust gases emitted from the vehicles are contributing to air pollution. These pollutants come from the incomplete combustion of fuel in vehicle engines and are harmful to both the environment and human health.
2. Scene b (Construction Site with Dust Clouds):
   • Main Pollutants: The pollutants here are dust and particulate matter (PM).
   • Type of Pollution: Air Pollution.
   • Reason: The dust generated by the construction activities, including earth-moving equipment, creates significant particulate pollution. This dust can affect air quality and can be harmful when inhaled, especially in areas with prolonged exposure.

These scenes both contribute to air pollution, with one primarily involving exhaust emissions from vehicles and the other involving dust from construction activities.
