What does the current AQI of 52 mean?

The AQI at Punjab Agricultural University, Ludhiana - PPCB is 52, classified as 'Satisfactory'. Generally acceptable, but sensitive groups should monitor exposure.

Is PM2.5 of 41.0 harmful?

PM2.5 level is 41.0 µg/m³, considered 'Satisfactory'. Fine particulate matter can penetrate deep into lungs and cause respiratory issues. People with asthma or heart disease should take precautions.

What does PM10 level of 50.0 mean?

PM10 is 50.0 µg/m³ at Punjab Agricultural University, Ludhiana - PPCB, marked as 'Good'. It indicates larger dust or pollen particles which may cause throat irritation or allergies.

What are the risks of CO at 52.0 mg/m³?

Carbon Monoxide is at 52.0 mg/m³. CO can reduce oxygen delivery in the body. High values are dangerous indoors and for people with cardiovascular conditions.

Why is ozone (O₃) important in air quality?

Ground-level ozone is 38.0 µg/m³. Though protective high up, it can cause respiratory problems when present in lower atmosphere, especially in sunlight-heavy hours.

20.0 📖 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.
