A recent study by researchers from the Laboratory for Atmospheric Chemistry at Paul Scherrer Institute (PSI) and the Indian Institute of Technology Kanpur found that fumes from wood used for heating and cooking, and airborne particulates from burning the remains of the previous season's crops, are the main contributors to the pollution in New Delhi

Burning Wood and Crops
is a Major Contributor

The pollution in New Delhi can exceed 500 micrograms per cubic meter of air, while in Beijing, a city that also struggles with air quality, 70 micrograms is typical

High Levels of Pollution

One of the most visible manifestations of pollution in New Delhi is the smog-infested air that is common during winter nights

Smog-Infested Air

Air quality in New Delhi is a serious concern, as it affects the health of the city's 20 million residents. During particularly bad smog, the capital orders school and business closings, and officials dispatch water and "anti-smog" machines to try and tackle the problem

Serious Health Concerns

The findings of the paper provide insight into the sources of pollution in New Delhi and highlight the need for measures to address the issue. By understanding the root causes of the problem, policymakers and residents can take steps to reduce the levels of pollution and improve the city's air quality

Root Causes of the Problem

It is essential to take measures to address the pollution problem in New Delhi. The government needs to create policies that encourage people to switch to cleaner sources of fuel and increase the use of public transportation. There is also a need for stricter regulations on industries and vehicles that emit harmful pollutants

Need for Measures

Addressing the pollution problem in New Delhi requires collaborative efforts from the government, industries, and residents. Everyone must work together to find sustainable solutions to reduce pollution levels and improve the quality of life for everyone living in the city

Collaborative Efforts

The high number of vehicles on the road in New Delhi is another significant contributor to air pollution. Cars and buses emit harmful gases such as nitrogen oxides and particulate matter, which can cause respiratory illnesses

Vehicular Emissions

Industries in and around New Delhi also emit large amounts of pollutants such as sulphur dioxide, nitrogen oxides, and particulate matter. These pollutants can cause serious health problems such as respiratory illness and cancer
