Mains Paper 3: Environment | Conservation, environmental pollution and degradation, environmental impact assessment

From UPSC perspective, the following things are important:

Prelims level: Environment-friendly crackers, CSIR, perchlorate

Mains level: Harmful effects of firecrackers and ways to reduce their usage

Environment-friendly crackers

  1. In a bid to fight air pollution, Science and Environment Minister has tasked the Council of Scientific and Industrial Research to come up with a way to make crackers that are “environmentally friendly”
  2. Several CSIR laboratories have come together and are putting together a robust S&T strategy for development of eco-friendly firecrackers and fireworks

How will this be done?

  1. The first phase will cover reduction of pollutants, while future strategies will cover removal of pollutants from the compositions
  2. A key ingredient in several crackers is perchlorate and replacing them with nitrogen-rich materials or nitrocellulose could make them burn cleaner and produce less smoke

Harmful effect of crackers

  1. Other than smoke-aggravating partially-burnt paper that sheaths the gunpowder in crackers, metals in fireworks such as strontium and barium are toxic to human and animal health
  2. The burning process produces other harmful emissions such as polychlorinated hydrocarbons
