*General Studies-3; Topic: Conservation, environmental pollution and degradation, environmental impact assessment.*
Introduction
• Air pollution is one of the most pressing environmental and public health crises globally. According to the World Health Organization (WHO), it is responsible for one in nine deaths worldwide, contributing to approximately 7 million premature deaths annually.
• The State of Global Air 2024 report highlighted that 1 million deaths in 2021 were linked to air pollution, making it the second-leading risk factor for mortality, particularly affecting children under the age of five.
• The deteriorating air quality has led to widespread health concerns, economic burdens, and environmental degradation, making it not just a governance issue but a public health emergency of grave significance.
Health Impacts of Air Pollution
• Respiratory Diseases: Particulate Matter (PM2.5 and PM10), which consists of tiny solid and liquid particles, can deeply penetrate the lungs, causing lung inflammation, chronic obstructive pulmonary disease (COPD), asthma, and respiratory infections. Studies have linked PM2.5 exposure to lung cancer, DNA mutations, and chronic lung conditions.

• Cardiovascular Disorders: Fine particulate matter affects the cardiovascular system, increasing the risk of heart attacks, hypertension, and stroke. The State of Global Air report indicated that cardiovascular complications due to pollution are a major cause of death, particularly in urban areas.

• Impact on Children and Cognitive Development: Prolonged exposure to PM2.5 affects children’s cognitive development, leading to learning disabilities, anxiety, and mental health issues. Studies suggest a strong link between air pollution and lower IQ levels, neurodevelopmental delays, and higher risks of ADHD (Attention Deficit Hyperactivity Disorder).

• Studies suggest a strong link between air pollution and lower IQ levels, neurodevelopmental delays, and higher risks of ADHD (Attention Deficit Hyperactivity Disorder).
• Elderly and Vulnerable Populations: Senior citizens and those with pre-existing conditions such as diabetes and hypertension are at higher risk due to weakened immune responses and aggravated heart conditions. PM2.5 contributes to cognitive decline and neurodegenerative diseases like Alzheimer’s and Parkinson’s.

Economic Consequences of Air Pollution
• Lower GDP Growth and Productivity Losses: The Dalberg Report (2019) estimated that air pollution costs Indian businesses $95 billion annually (3% of GDP) due to decreased worker productivity and health-related absenteeism. Air pollution-induced illnesses contribute to reduced workforce efficiency, higher insurance claims, and increased healthcare expenses.

Major Causes of Air Pollution
• Vehicular Emissions: Transport contributes significantly to PM2.5 and PM10 levels, particularly in urban areas. In Delhi, vehicular pollution accounts for 40% of PM2.5 emissions, with private vehicle ownership rising rapidly. Diesel-powered vehicles release NO₂ and sulfur dioxide (SO₂), causing smog and acid rain.

Mitigation Strategies and Policy Interventions
• Strengthening Public Transport Infrastructure: Only 39% of India’s population has access to public transport, leading to higher private vehicle dependence. Investments in metro rail expansion, electric buses, and last-mile connectivity can reduce vehicular emissions.
