What are the factors contributing to Delhi being the most polluted city in the world, as per a Swiss survey

Factors contributing to Delhi being the most polluted city in the world, as per a Swiss survey, include:

• Vehicular Emissions: Delhi has a large number of vehicles, and their emissions significantly contribute to air pollution.
• Industrial Activities: The extensive industrial activities and factories in and around Delhi release pollutants into the air.
• Burning of Biomass: The burning of crop residues, wood, and other biomass in the nearby agricultural regions adds to the pollution.
• Dust and Construction Activities: Uncontrolled dust from construction sites and unpaved roads increases the particulate matter in the air.
• Geographical Factors: Delhi's landlocked location, surrounded by the Aravali hills, restricts the dispersion of pollutants.

The high pollution levels in Delhi have severe implications for the environment and public health. The air quality index often reaches hazardous levels, leading to respiratory issues such as asthma, lung diseases, and allergies. Additionally, long-term exposure to pollution increases the risk of cardiovascular diseases, cancer, and even premature death. The pollution also affects the quality of soil, water bodies, and ecosystems, leading to a negative impact on agriculture and biodiversity. Elevated pollution levels hamper the overall quality of life in the city, affecting productivity, tourism, and economic growth. It is crucial for the authorities to address these factors and take appropriate measures to reduce pollution and protect public health.
