The Environment Ministry has tasked the Council of Scientific & Industrial Research (CSIR)-National Physical Laboratory (NPL) with certifying air quality monitoring instruments/sensors.

• Currently, Delhi leads the numbers of cities, with around 35 air quality sensors maintained by the CPCB.

 

What

• The Central Government designates the CSIR-NPL as a national verification agency for certifying instruments and equipments for monitoring emissions and ambient air.
• CSIR-NPL shall develop the necessary infrastructure, management system, testing and certification facilities conforming to international standards.
• This is in anticipation of rising demand by States — against the backdrop of the National Clean Air Campaign — for low-cost air quality monitoring instruments that can monitor levels of ozone, particulate matter and nitrous oxides.

 

National Clean air campaign

Under NCAP, the Centre has the task of delivering by 2024 its target of 20-30% reduction in PM 2.5 (fine, respirable pollution particles) and PM 10 (coarse pollution particles) concentration in 102 non-attainment cities over 2017 levels.

Non-attainment cities are those that did not meet the annual PM 10 national standard from 2011 to 2015.

A building of this initiative is to have a huge monitoring network of sensors that can capture the rapid fluctuations of pollutants, necessary to ascertain how these gases and particles affected health.
