Delhi's air quality remained "very poor" on Tuesday due to slow wind speed and high humidity, authorities said , even as a study pointed out that during the past two decades, Delhi's air quality was the "most deadly" in 2016 as it reduced the life expectancy of a resident by over 10 years.

According to the Centre-run System of Air Quality and Weather Forecasting (SAFAR), the overall air quality index (AQI) was recorded at 349 on Tuesday morning, which comes under the "very poor" category.

On Tuesday, the PM2.5 particles in the air with a diameter of less than 2.5 micrometres level was recorded at 184, while the PM10 level was recorded at 309, the CPCB data said.

The air quality in Ghaziabad, Faridabad, Noida and Greater Noida was "poor" while Gurgaon recorded "moderate" air quality, it said.

An AQI between 0 and 50 is considered "good", 51 and 100 "satisfactory", 101 and 200 "moderate", 201 and 300 "poor", 301 and 400 "very poor", and 401 and 500 "severe".

Even as the study asserted that the capital was the second among 50 most polluted areas of the country, the Supreme Court-empowered Environment Pollution (Prevention and Control) Authority (EPCA) Chairman Bhure Lal said enforcing agencies were "completely dormant" and bodies like the DDA and the MCD were indulging in a blame game.

Speaking at an event, Lal stressed the need to strengthen public transport, especially the bus fleet, while asserting that there was a "laxity of administration" in adopting measures for combating pollution.

North Delhi Mayor Adesh Gupta, however, rejected the allegation saying, the civic body "follows all instructions" as directed by the apex court-appointed monitoring committee while DDA Vice-Chairman Tarun Kapoor said the urban body discharged all its duty diligently.

Meanwhile, according to air quality life index and an accompanying report produced by the Energy Policy Institute at the University of Chicago (EPIC), during the past two decades, Delhi's air quality was the "most deadly" in 2016 as it reduced the life expectancy of a resident by more than 10 years.

The study said the capital was the second among 50 most polluted areas of the country, while adding that India is today the world's second most-polluted country trailing only Nepal.

The study pointed out that over the past two decades, the concentration of fine particulates increased by 69 per cent on an average across India, reducing the life expectancy of a typical Indian citizen by 4.3 years compared to 2.2 years in 1998.

It said concentrations of particulate pollution in India's northern states of Bihar, Uttar Pradesh, Haryana, Punjab and the Capital Territory of Delhi are "substantially higher" and the impact on life expectancy exceeds six years.

It added that pollution is the "single greatest threat" to human health globally, with its effect on life expectancy exceeding that of devastating communicable diseases such as tuberculosis and HIV/AIDS, behavioural killers like cigarette smoking, and even war.

Seventy-five per cent of the global population or 5.5 billion people live in areas where particulate pollution exceeds the WHO guideline.

"The AQLI reveals that India and China, which make up 36 per cent of the world's population, account for 73 per cent of all years of life lost due to particulate pollution," it said.

In Delhi, the PM2.5 concentration was 114 g/m3 in 2016 which is 1.6 times more than 70 g/m3 in 1998, the study said.

The AQLI is based on a pair of peer-reviewed studies that quantify the causal relationship between long-term human exposure to particulate pollution and life expectancy.
