⚠️ Vulnerable Groups — Special Risks
🤰 Pregnancy & Fetal Development
Air pollution crosses the placenta. Effects on unborn children:
- Low birth weight: 15-20% higher risk at high PM2.5
- Preterm birth: 10% increased risk
- Smaller head circumference: Linked to cognitive delays
- Stillbirth: 2-3% increased risk
- Autism/ADHD: Emerging evidence of links
Advice: Pregnant women should avoid outdoor exercise when AQI >100. Use air purifier in bedroom.
Sources: Lancet Planetary Health 2022, ICMR studies
👶 Children (0-14 years)
Children are not small adults — they're uniquely vulnerable:
- Breathe 50% more air per kg body weight
- Lungs still developing until age 18
- Play closer to ground (higher PM concentration)
- Cannot self-protect (won't complain of symptoms)
- Lifetime impact: Early damage = lifelong reduced lung capacity
Impact: Delhi children have 40% reduced lung capacity vs. clean air cities (CPCB study).
🧠 Mental Health Impact
Air pollution affects the brain, not just lungs:
- Depression: 10% higher risk at high PM2.5
- Anxiety: Elevated cortisol from pollution stress
- Cognitive decline: Accelerated in elderly
- Dementia risk: 40% higher in polluted areas
- Children: Lower IQ scores, behavioral issues
Mechanism: PM2.5 particles can reach the brain via olfactory nerve, causing inflammation.
Sources: Lancet Neurology 2021, AIIMS Delhi research
👴 Elderly (65+)
- Weakened immune response
- Pre-existing heart/lung conditions
- Less able to avoid exposure
- Higher hospitalization rates
🏃 Outdoor Workers
- Traffic police, delivery workers, construction
- 8-12 hours daily exposure
- Heavy breathing increases intake
- No protective equipment provided

GRAP Stages Explained
🆕 Dec 2024: GRAP now uses predictive activation (3-day forecast via IMD/IITM) instead of reactive triggers
Stage I (201-300): Water sprinkling, dust control
Stage II (301-400): DG set ban, parking fees 4x
Stage III (401-450): Construction ban, mining ban
Stage IV (450+): Truck entry ban, 50% WFH, school closures
Policy Recommendations — What Should Change
Evidence-based recommendations for more effective air quality management. These are citizen suggestions for policymakers.
🚨 72-Hour Persistence Rule for GRAP
Problem: GRAP stages are currently relaxed as soon as AQI dips below threshold, even briefly. This "yo-yo" effect leads to:
- Premature lifting of restrictions
- Pollution rebounds within 24-48 hours
- Public confusion about what rules apply
- Loss of cumulative health protection
Recommendation: GRAP stage should only be downgraded when AQI remains consistently below the threshold for at least 72 hours (3 consecutive days).
Rationale: Weather patterns typically cycle over 3-5 days. 72-hour persistence ensures improvement is sustained, not a temporary dip.
⏰ Anticipatory Activation
Problem: GRAP is reactive — activated only after AQI crosses threshold. By then, damage is done.
Recommendation:
- Use weather forecasts + stubble fire satellite data to predict AQI 48-72 hours ahead
- Activate GRAP stages proactively when forecast shows likely breach
- IMD already provides forecasts — integrate with GRAP trigger
Example: If weather + fire data predicts AQI 400+ in 48 hours, activate Stage III immediately.
🏫 Automatic School Closures
Problem: Schools remain open even during AQI 400-500. Children are most vulnerable.
Recommendation:
- AQI 200+: Mandatory indoor-only activities, no outdoor PT
- AQI 300+: Optional attendance, online available
- AQI 400+: Automatic closure, shift to online
- Real-time AQI monitors in every school (mandatory)
Legal basis: Right to Life (Article 21) includes right to clean air.
💰 Stubble — Fix the Economics
Problem: Burning is rational for farmers. Bans without alternatives don't work.
Recommendation:
- Direct cash transfer of ₹2,500/acre for non-burning (UP model)
- Same-season subsidy for Happy Seeder (not 2-year delay)
- Stubble procurement by biomass plants at MSP
- Free PUSA decomposer with doorstep delivery
Evidence: Punjab fires down 50%+ in districts with effective cash transfer programs.
🏭 Year-Round Industrial Standards
Problem: Industrial restrictions only during GRAP. Pollution is year-round problem.
Recommendation:
- Permanent emission standards for NCR industries (not seasonal)
- Mandatory pollution control equipment with real-time monitoring
- Public dashboard showing factory-wise emissions
- Automatic penalties via IoT sensors (not manual inspection)
🚗 Congestion Pricing (Not Odd-Even)
Problem: Odd-even has minimal impact (2-4% reduction) with high compliance cost.
Recommendation:
- Congestion charge for private vehicles entering central Delhi (like London, Singapore)
- Dynamic pricing based on AQI (higher fee on bad air days)
- Revenue funds public transport and EV infrastructure
- Exemptions for EVs, carpools, essential services
Evidence: London congestion charge reduced traffic 15%, emissions 12%.
Take Action: Use these recommendations in RTI applications, letters to MPs/MLAs, or media advocacy.

What Worked Globally — Success Stories
Other cities faced similar crises and fixed them. Delhi can too.
🇨🇳 Beijing, China
Problem: 2013 "Airpocalypse" — PM2.5 over 500 for weeks. Called "unlivable."
Solution:
- Closed/relocated 2,000+ factories
- Coal ban in surrounding provinces
- Strict vehicle quotas (lottery system)
- Massive public transit expansion
- ₹12,000 Cr/year enforcement
Result: PM2.5 down 50% in 6 years (2013-2019)
🇬🇧 London, UK
Problem: 1952 Great Smog killed 12,000. Chronic pollution through 1990s.
Solution:
- Clean Air Act 1956 (banned coal burning)
- Congestion charge 2003 (£15/day to enter central London)
- Ultra Low Emission Zone 2019
- Diesel scrappage schemes
- Public naming of polluting vehicles
Result: NO2 down 44% since 2016. Congestion down 15%.
🇺🇸 Los Angeles, USA
Problem: 1970s smog so bad children couldn't play outside. "Smog capital."
Solution:
- Catalytic converters mandated (1975)
- Strict CARB vehicle standards
- Refinery emission controls
- Electric vehicle incentives
- 40 years of consistent enforcement
Result: Ozone down 70%, PM2.5 down 50% since 1980.
🇮🇳 Surat, India
Problem: 1994 plague outbreak linked to poor sanitation and air quality.
Solution:
- Complete municipal overhaul
- Industrial relocation
- Strict waste management
- Public-private partnerships
- Citizen engagement campaigns
Result: Now India's second cleanest city (Swachh Survekshan)
Common Thread: All success stories required (1) political will at the highest level, (2) sustained enforcement over years, (3) significant financial investment, and (4) public pressure. None were solved in one election cycle.

💰 Budget & Fund Utilization
NCAP Funds (2019-2025)
- Allocated: ₹11,211 crore to 131 cities
- Utilized: ~₹7,594 crore (68%) — CREA 2025
- Delhi shame: ₹81.36 Cr allocated, only ₹14.1 Cr (17%) spent — RTI Jan 2025
- Where it went: 64% on dust control (sweeping, sprinkling) — CSE
- What's missing: Only 50/130 cities completed source apportionment
Source: RTI Jan 2025, CREA Report April 2025, CSE Assessment
State Budgets for Air Quality
- Delhi (2024-25): ₹500 Cr (0.6% of budget)
- Punjab stubble: ₹300 Cr (mostly unspent)
- Haryana: ₹150 Cr (for 14 cities)
- UP: ₹400 Cr (mostly road dust)
Compare: Delhi health budget ₹9,800 Cr. Pollution causes 10-15% of health burden.
🎪 Who's Responsible? The Blame Game Decoded
Delhi Government
- Local transport (buses, autos)
- Municipal waste burning
- Construction dust in Delhi
- Industrial emissions (local)
- Road dust management
~35-40% of winter PM2.5
Punjab/Haryana
- Stubble burning (Oct-Nov)
- Brick kilns
- Industrial clusters
- Thermal power plants
~25-35% during peak burning season
Central Government
- Vehicle emission standards
- Fuel quality (BS-VI)
- NCAP funding & oversight
- Interstate coordination
- Thermal plant norms
Policy framework & inter-state issues
The Real Problem: Everyone points to everyone else. CAQM was created in 2021 to coordinate, but has limited enforcement power. Solution requires political will across party lines.

Take Action — What You Can Do
Practical, science-backed actions at every level — from your home to your community. Organized by context and budget. Every small action compounds.
Your Home GRAP — Personal Emergency Response
Just like the city has GRAP stages, create your own household response plan based on AQI levels.
| AQI Level | Your Home Response | Kids & Elderly | Outdoor Activity |
|---|---|---|---|
| 0-50 Good | Normal activities. Open windows for ventilation. | All activities normal | ✅ All outdoor activities |
| 51-100 Moderate | Sensitive individuals limit prolonged outdoor exertion | Reduce intense outdoor play | ⚠️ Limit strenuous exercise |
| 101-200 Poor | Keep windows closed. Run air purifier if available. | Indoor play preferred | 🚫 No jogging/cycling outdoors |
| 201-300 Very Poor | Seal windows. Wet mop floors. N95 if going out. | Stay indoors. No school commute if possible. | 🚫 Essential trips only with N95 |
| 301-400 Severe | DIY air filter running. Damp towels on gaps. Mask indoors if no purifier. | Consider staying with relatives in cleaner area | 🚫 Stay home. Work from home if possible. |
| 400+ Hazardous | Emergency mode. Multiple purifiers. Consider temporary relocation. | Relocate if child/elderly has respiratory condition | 🚫 Complete lockdown. Emergency only. |
🏠 Household Actions — By Budget
₹0 — Zero Cost Actions
- Wet mopping — Mop floors 2x daily to trap settled PM2.5 (study: reduces indoor PM by 20-30%)
- Spray plants — Mist indoor/balcony plants 2x daily; leaves trap particulates
- Seal gaps — Use wet towels/cloth to seal door & window gaps
- Cook timing — Avoid frying during peak pollution hours (6-10 AM)
- No agarbatti/dhoop — Incense adds PM2.5; skip during high AQI days
- No dry sweeping — Resuspends dust; always wet mop instead
- Nasal rinse — Saline water gargle & nose cleaning after outdoor exposure
- Kitchen exhaust — Always use chimney/exhaust while cooking

😷 Masking Guide — What Actually Works
| Mask Type | PM2.5 Filtration | Cost | Verdict |
|---|---|---|---|
| Cloth/Cotton | 10-30% | ₹20-50 | ❌ Useless for PM2.5 |
| Surgical mask | 30-50% | ₹5-10 | ⚠️ Better than nothing |
| N95 (no valve) | 95% | ₹50-150 | ✅ Recommended |
| N99 | 99% | ₹150-300 | ✅ Best protection |
| N95 with valve | 95% (inhale only) | ₹100-200 | ✅ Easier breathing |
Key: Look for BIS certification (IS 9473). "N95" without certification may be fake.
Proper Mask Usage
- Fit test: No gaps around nose/chin. Glasses fogging = bad seal.
- Replace: Every 3-5 days of regular use, or when breathing becomes difficult
- Kids: Need kid-sized N95. Adult masks don't seal properly.
- Beard: Facial hair breaks seal. Clean-shaven for best protection.
- Two-strap: Better seal than ear-loop style
- Don't touch: Avoid touching mask surface; contaminants transfer
🏫 For Schools — Admin & Parents
What Schools Should Do
- AQI-based schedule — No outdoor PT/games when AQI >200
- Indoor assembly — Shift morning assembly indoors during bad days
- Air purifiers — At minimum in nursery/KG classrooms
- Seal classrooms — Weather stripping on windows, door draft stoppers
- Green buffer — Plant trees on roadside boundary
- Bus route timing — Avoid peak traffic hours if possible
- Online option — Hybrid mode during severe pollution (AQI >400)
Reference: CPCB School Guidelines 2023
What Parents Can Demand (Legal Basis)
- CAQM Direction 2024: Schools must suspend outdoor activities when AQI >400
- Right to Education: Schools must provide safe environment
- NGT Orders: Multiple orders mandate AQI monitoring in schools
- Form a group: Parent WhatsApp group to coordinate pressure

🌾 Rural vs 🏙️ Urban — Context-Specific Actions
🌾 Rural Areas
Main sources: Crop burning, biomass cooking, dust roads, brick kilns
- Stubble alternatives:
- Happy Seeder (₹1.5L, subsidy available)
- Sell to biomass plants (₹1000-1500/tonne)
- In-situ decomposition with PUSA bio-decomposer (free from govt)
- Cooking: LPG > biomass chulha. PM2.5 from chulha = smoking 400 cigarettes/day
- Brick kilns: Report illegal kilns to SPCB. Zigzag technology mandate.
- Road dust: Demand paving from Gram Panchayat. MGNREGA funds available.
- Timing: Avoid working in fields early morning (mist traps pollution)
Subsidy: Contact District Agriculture Officer for Happy Seeder
🏙️ Urban Areas
Main sources: Vehicles, construction, industry, road dust, waste burning
- Transport:
- Metro/public transport when possible
- Carpool apps (Quick Ride, etc.)
- WFH during severe pollution

About JanVayu जनवायु
JanVayu (Air Memory) is a citizen-led, open-source air quality archive for India. It exists because air pollution is not just an environmental issue — it is a public health emergency, an economic drain, and a failure of governance that demands transparency and accountability.
Why JanVayu Exists
The Problem: India has the world's worst air quality. Delhi regularly exceeds WHO safe limits by 20-40x. Over 2 million Indians die annually from air pollution — more than malaria, TB, and HIV combined. Yet public discourse remains fragmented, data is scattered, and accountability is absent.
The Gap: Official dashboards show data but don't translate it into health risks. Research papers exist but aren't accessible to citizens. Politicians make promises but no one tracks outcomes. RTI is powerful but intimidating for most citizens.
Our Response: JanVayu bridges these gaps by integrating live data, health science, economic analysis, and accountability tools into a single, accessible platform — designed for citizens, journalists, researchers, and advocates.
Our Principles
Open & Transparent
All code is open-source. All data sources are cited. All methodologies are documented. No hidden agendas.
Evidence-Based
We use peer-reviewed research (Lancet GBD, WHO, IHME) and established methodologies (GEMM, World Bank). No speculation.
Citizen-Centered
Designed for ordinary citizens, not just experts. Translates complex data into actionable insights and empowerment tools.
Accountability-Focused
We track political promises, grade policy effectiveness, and provide RTI templates because change requires pressure.

Limitations & Disclaimers
Not Medical Advice: Health risk calculators provide estimates based on population-level research. Individual risk varies. Consult healthcare providers for personal medical decisions.
Data Accuracy: Live AQI depends on WAQI API and underlying monitoring station reliability. Some stations may have gaps or calibration issues.
Economic Estimates: Productivity loss calculations use simplified models. Actual business impact depends on many factors not captured here.
