Hi readers. Sorry for posting so late, but we've all had a really busy weekend!
Delhi is one of the most air-polluted cities in the world. In January 2025, Delhi was ranked as India's second most polluted city.
Here are some causes of Delhi's pollution problem:
• Air pollution in Delhi is caused by road dust, vehicles, construction dust, industrial point sources, and domestic fuel burning.
• Health effects: Exposure to high levels of air pollution can cause respiratory infections, heart disease, and lung cancer.
• Seasonality:Delhi experiences thick smog in the winter, which leads to poor air quality.
• Vehicular emissions: About 40% of Delhi's air pollution is caused by vehicular emissions, with diesel vehicles being a major contributor.
• Industrial point sources: Industrial point sources are a major contributor to PM10 and SO2 emissions.
• Road dust
Road dust is a major contributor to PM2.5 and PM10 pollution.
• Construction dust: Construction dust is a major contributor to air pollution in Delhi.
• Population density: Delhi's high population density leads to heavy traffic and significant emissions of pollutants.
