Slide 8 - Primary Anthropospheric Sources
- Transportation: 25-35% of NOx & PM emissions
- Industrial processes: SO2, heavy metals, VOCs
- Power generation: Coal plants contribute 25% PM globally
- Agriculture: 50%+ ammonia (NH3) emissions
- Residential: Biomass burning, heating fuels

Slide 9 - Key Pollutants & Effects
Major Pollutants PM2.5 & PM10: Fine particles from combustion NOx: From vehicles/industry, forms smog SO2: Coal/oil burning, acid rain VOCs: Solvents/fuels, ozone precursor CO: Incomplete combustion NH3: Agriculture/livestock
Impacts Respiratory diseases, heart attacks Ground-level ozone, asthma Lung damage, ecosystem acidification Secondary ozone formation Hypoxia, poisoning Eutrophication, haze
Slide 10 - Mitigation Strategies
🌿 Renewable Energy Shift to solar/wind reduces SO2/NOx by 70% in power sector
🚗 Electric Vehicles Cut transport emissions; EV adoption up 40% yearly
🏭 Emission Controls Scrubbers/filters in industry capture 90% pollutants
🌾 Sustainable Ag Precision farming cuts NH3 by 30%
♻️ Waste Reduction Recycling/incineration controls methane/PM
