New Delhi, Sep 24 (PTI) Staying indoors to avoid toxic outdoor air in the national capital may not serve the purpose anymore as pollutants have now entered homes.

A new study has revealed that air inside homes in Delhi have become unsafe with high levels of pollutants found in it, despite keeping doors shut.

“Houses in the city have very polluted air infested with large concentrations of PM2.5, carbon dioxide and harmful gases, with long-term health implications,” said a study conducted by BreatheEasy Consultants with real-time monitoring of air quality inside more than 400 homes in Delhi-NCR spread across 200 large and small residential colonies.

The study was conducted between April 2018 and March 2019 by BreatheEasy Consultants, indoor air quality experts.

The study claims that it assessed air quality inside various types of homes with respect to three air-borne pollutants — particulate matter 2.5, Carbon Dioxide (CO2), and Total Volatile Organic Compounds (TVOCs) — that are emitted as gases from certain solids and liquids inside homes.
