India's rising air pollution crisis has made its cities among the most polluted in the world, with the worst-affected urban centers worldwide. This catastrophic scenario indicates not only an environmental difficulty, but also a governance issue, as policy implementation and enforcement remain inadequate.
What is Air Pollution?
Air pollution is the presence of dangerous elements in the atmosphere, such as gases, particulate matter and biological molecules, which impact the environment, human health, and other species. It is a result of both natural and human activities.
A) Natural sources:
1.Volcanic eruptions that emit gasses and ash.
2.Wildfires produce smoke and carbon.
3. Dust storms.
4. OZONE (O3)
B) Anthropogenic (human-made) Sources:
1. Industrial emissions: It include pollutants such as sulfur dioxide (SOâ‚‚) and nitrogen oxides (NOâ‚“) from factories and power plants.
a)PM2.5 - PM2.5 particles, which have a diameter of 2.5 micrometers or less, are roughly 30 times smaller than a human hair, posing a major but frequently undetected danger to air quality.
b)PM10 particles have a diameter of 10 µm or less.
c)NO2 - NO2 can create impaired atmospheric visibility and increase atmospheric heat. This occurs when its quantities absorb visible radiation in the atmosphere.
d)SO2 (Sulfur Dioxide)- Sulfur dioxide is the major component in acid rain as it easily dissolves in the water and forms sulfuric acid. SO2 in acid rain can destroy forests, crops, and aquatic ecosystems, alter soil acidity, and corrode building materials and historical monuments.
2. Vehicle Emissions: Vehicles emit CO, hydrocarbons, and particulate particles.
a)Carbon Monoxide (CO) - CO emissions create global and climate changes in the atmosphere by raising or changing sea and land temperatures. It alters ecosystems, increases storm activity, and influences other weather occurrences.
3. Fossil fuel combustion: Coal, oil, and natural gas are burned to generate energy.
4. Agricultural activities: It emits methane from cattle, ammonia from fertilizers, and CO2 from crop burning.
5. Waste Burning: The open burning of rubbish emits harmful gasses.
Effects on Humans and Other Organisms:
a)Short-term exposure impacts:
1. Eye irritation: redness, itching, and discomfort in your eyes.
2.Headaches—frequent or severe headaches.
3.Fatigue- experiencing unusual tiredness or weakness.
4.Aggravated asthma means more asthma attacks and symptoms.
5.Breathing difficulties include coughing, wheezing, and shortness of breath.
b)Long-term impacts:
1. Respiratory Conditions: Asthma, bronchitis, lower respiratory infections, and chronic obstructive pulmonary disease (COPD).
2. Cardiovascular Diseases: Air pollution can cause heart attacks, strokes, and ischemic heart disease.
3.Cancer: Prolonged exposure to pollutants such as benzene and fine particulate matter can result in tracheal, bronchial, and lung cancer.
4.Cognitive and Neurological Damage: A link to Alzheimer's disease, developmental difficulties in children, and newborn disorders.
5.Premature Deaths: Ambient and household air pollution cause 6.7 million premature deaths per year.
On other organisms:
Plants: Airborne poisons harm leaves, limit photosynthesis, and stunt growth.
Animals: They suffer from same respiratory and cardiovascular difficulties as people, as well as toxic bioaccumulation.
Ecosystems: Air pollution causes acid rain, which destroys aquatic life, forests, and soil health.
Future Complications of Air Pollution:
1. Climate Change: Greenhouse gases, such as COâ‚‚ and methane, trap heat, contributing to global warming.
2.Biodiversity Loss: Habitats are destroyed as a result of contaminated air and related climate consequences.
3.Reduced Agricultural Productivity: Ozone pollution harms crops, lowering yields.
4.Public Health Crisis: Diseases worsen, healthcare expenditures rise, and life expectancy falls.
5. Economic Losses: Decreased workforce productivity and greater spending on pollution mitigation.
Why Should We Consider It a Big Problem Right Now?
1.Scale of Impact: Air pollution impacts more than 99% of the world's population, which breathes dangerous air.
2.Irreversible Damage: Continued pollution has long-term environmental and health implications.
3.Link to Climate Change: Air pollution hastens global warming, resulting in cascade effects.
4.Economic Strain: Premature deaths and illnesses cost billions of dollars each year.
India's current air pollution situation:
Severe Air Quality: India has the world's most polluted cities, with an AQI of more than 350.
Sources: It's include vehicular pollutants, industrial pollution, construction dust, crop residue burning, and coal-fired power stations.
Seasonal Impact: Stubble burning and weather patterns contribute to poor air quality during the winter.
Health Impact: Air pollution causes more than a million premature deaths in India each year.
Governmental Actions: The Ministry of Environment, Forest, and Climate Change (MoEFCC) began the National Clean Air Programme (NCAP) in January 2019, with the goal of improving air quality in 131 cities across 24 states/UTs by engaging all stakeholders. The program aims to achieve reductions of up to 40% or meet the National Ambient Air Quality Standards for Particulate Matter 10 (PM 10) by 2025-26.
Measures to reduce air pollution:
A) Policy Level Actions:
1.Transition to Clean Energy: Replace coal with renewable energy sources such as solar, wind, geothermal, and hydropower.
2.Stricter Emission Standards: Enforce laws on companies and automobiles to reduce pollution.
3.Public Transport: Enhance public transportation networks to lessen dependency on personal vehicles.
4.Prohibit stubble burning and promote alternatives such as bio-decomposers for agricultural residue.
5.Massive awareness campaigns should be organized to promote the conservation of nature and natural resources such as air, water, forest, and soil.
B) Technological Interventions:
1.Use Cleaner Technologies: Electric cars (EVs) and cleaner industrial processes.
2.Air Purification Systems: Install large-scale air purifiers in cities.
3.Monitoring Systems: Install air quality monitoring systems to collect real-time data and provide actionable insights.
C) Community-Based Actions:
1.Awareness Campaigns: Educate people on the causes and consequences of air pollution.
2.Afforestation: Planting trees to serve as carbon sinks and enhance air quality.
3. Reduce garbage Burning: Encourage recycling and garbage segregation.
D)Individual contributions:
1.Reduce Your Vehicle Use: Consider carpooling, cycling, or taking public transportation.
2.Energy Conservation: Use energy-efficient appliances to lower your electricity consumption.
3.Support Green Initiatives: Take part in tree-planting efforts and cleanup activities.
Air pollution is a catastrophe that requires immediate attention and action. As India urbanizes at an unprecedented rate, these dirty cities serve as a sharp reminder of the critical need for sustainable development, stricter rules, and a concerted effort by citizens, government and industry, can move toward cleaner air and a healthier planet.
