How does the Air Act of 1987 impact environmental regulation?

The Air Act of 1987 primarily aimed to improve air quality and regulate air pollution within India. One of its significant aspects is the strengthening of noise pollution control. While the Act focuses mainly on air pollution, it recognizes the importance of maintaining a healthy environment, which includes managing noise as a pollutant that can impact human health and well-being. By addressing noise pollution, the Act broadens its regulatory scope, emphasizing the need to control various forms of pollution for a cleaner environment.

The other options do not accurately reflect the primary focus and provisions of the Air Act of 1987. The Act does not add more pollutants to the list; rather, it aims to regulate and control established pollutants. Although noise pollution is addressed, the Act's main focus is air quality, which means it does not specifically regulate water resources. Thus, the correct answer highlights a crucial aspect of environmental regulation as provided by this legislation.
