 Indoor air pollution monitoring and regulation in India are primarily guided by the Air (Prevention and Control of Pollution) Act, 1981, though its focus is largely on outdoor air quality. While the Act doesn't explicitly address indoor air, the need for regulation is growing, especially in enclosed public spaces. The Central Pollution Control Board (CPCB) and State Pollution Control Boards are responsible for monitoring and controlling air pollution, including potentially taking samples of indoor air emissions. 

Here's a more detailed look:

1. The Air (Prevention and Control of Pollution) Act, 1981: 

Enacted to prevent, control, and abate air pollution. 

Establishes Boards (CPCB and State Boards) to carry out these functions. 

Grants the Boards the power to monitor air quality and take samples for analysis. 

While focused on outdoor air, the Act's preamble emphasizes the preservation of air quality, raising questions about its applicability to indoor environments. 

The Act was amended in 1987. 

2. Indoor Air Quality Concerns:

Indoor air pollution can be a significant health risk, with pollutants like radon, mold, and volatile organic compounds (VOCs). 

WHO: has issued guidelines for indoor air quality related to household fuel combustion. 

CPCB: also coordinates with other agencies for monitoring air quality. 

State Pollution Control Boards: play a role in monitoring and controlling pollution. 

3. Monitoring and Standards:

National Ambient Air Quality Monitoring Programme (NAMP): monitors air quality parameters. 

CPCB: provides technical and financial support for monitoring stations. 

Quality assurance: is crucial in air quality monitoring to ensure data accuracy. 

4. Emerging Trends:

Low-cost sensors (LCS): are being developed and used for indoor air quality monitoring. 

Source apportionment methods: are being used to identify and mitigate indoor air pollution sources. 

Community-based research: is emerging, with initiatives like the LUCIR study involving youth in characterizing indoor pollutants. 

5. Legal and Regulatory Gaps:

There is a need for more specific regulations and guidelines for indoor air quality in India. 

WHO: has published health-based guidelines for indoor air quality, which can serve as a reference. 

ISO 16000: provides standards for various indoor air pollutants. 

In conclusion: While India's primary air pollution law doesn't explicitly cover indoor air, the need for monitoring and regulation is recognized. Emerging technologies and research are paving the way for more effective indoor air quality management, and further development of specific regulations is needed.
