📖 What Each Pollutant Tells You
Each pollutant plays a unique role in determining air quality. Here's what the values above actually mean for your health and environment:
-
🌫 PM2.5 (Fine Particulate Matter):
Microscopic particles that go deep into the lungs. Long exposure can worsen asthma, heart issues, and
respiratory illnesses.
Safe: 0–30 | Caution: 31–60 | Hazard: 90+ -
🌬 PM10 (Coarse Particulates):
Larger dust and pollen particles. Can irritate the eyes, throat, and cause coughing or short breath.
Safe: 0–50 | Moderate: 51–100 | Poor: 101+ -
💨 NO₂ (Nitrogen Dioxide):
A key traffic-related pollutant. High levels are linked to reduced lung function and increased hospital
visits.
Safe: 0–40 μg/m³ | Moderate: 41–80 | Risky: 81+ -
🛢 CO (Carbon Monoxide):
Released from incomplete combustion (vehicles, stoves). In high concentrations, it limits oxygen to vital
organs.
Safe: 0–1 mg/m³ | Elevated: 1.1–2 | Unsafe: 2.1+ -
☀️ O₃ (Ozone):
Formed by chemical reactions in sunlight. While good in the upper atmosphere, ground-level O₃ is harmful to
lungs.
Acceptable: 0–50 | Moderate: 51–100 | Dangerous: 101+ -
🏭 SO₂ (Sulfur Dioxide):
Produced by burning coal or oil. Short-term exposure irritates the eyes, nose, and throat. Long-term effects
can damage lungs.
Safe: 0–40 | Moderate: 41–80 | Risky: 81+
Note: Children, older adults, and people with respiratory conditions should reduce outdoor
exposure when pollutant levels cross into the caution zone.
🤔 FAQs About IESD Banaras Hindu University, Varanasi - UPPCB Air Quality
The AQI at IESD Banaras Hindu University, Varanasi - UPPCB is 32, classified as
Good.
Air quality is healthy and safe for all.
PM2.5 at this station is 17.0, classified as
Good. Fine particles like these can enter your lungs and bloodstream,
especially dangerous for people with asthma or heart issues. Avoid outdoor exercise if levels exceed 60
µg/m³.
PM10 is currently 32.0 at IESD Banaras Hindu University, Varanasi - UPPCB, labeled
Good. This indicates presence of coarse dust and pollen. If you're
sensitive to dust or allergens, consider wearing a mask or avoiding dusty areas.
Carbon Monoxide is measured at 5.0 mg/m³ here. While safe under 1 mg/m³,
higher levels can reduce oxygen delivery to organs. Vulnerable groups should avoid enclosed, polluted
spaces.
O₃ level is 6.0. While ozone protects us high in the atmosphere, ground-level
ozone is harmful, especially during hot afternoons. It can trigger coughing and lung discomfort.
Nitrogen Dioxide is 2.0 µg/m³ – a marker of traffic pollution. If you're in a
high-traffic area or sensitive to respiratory irritants, it's wise to avoid peak rush hours outdoors.
