What does the current AQI of 59 mean?

The AQI at Srinivas Nagar Colony, Machilipatnam - APPCB is 59, classified as 'Satisfactory'. Generally acceptable, but sensitive groups should monitor exposure.

Is PM2.5 of 59.0 harmful?

PM2.5 level is 59.0 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 58.0 mean?

PM10 is 58.0 µg/m³ at Srinivas Nagar Colony, Machilipatnam - APPCB, marked as 'Satisfactory'. It indicates larger dust or pollen particles which may cause throat irritation or allergies.

Should I worry about NO₂ being 18.0 µg/m³?

NO₂ level is 18.0 µg/m³. Higher levels often come from vehicle emissions and may aggravate lung diseases. Consider reducing time near heavy traffic if you're sensitive.

What are the risks of CO at 19.0 mg/m³?

Carbon Monoxide is at 19.0 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 4.0 µg/m³. Though protective high up, it can cause respiratory problems when present in lower atmosphere, especially in sunlight-heavy hours.

13.0 📖 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.

🤔 FAQs About Srinivas Nagar Colony, Machilipatnam - APPCB Air Quality

The AQI at Srinivas Nagar Colony, Machilipatnam - APPCB is 59, classified as Satisfactory. Acceptable, but people with respiratory conditions should still be cautious.

PM2.5 at this station is 59.0, classified as Satisfactory. 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 58.0 at Srinivas Nagar Colony, Machilipatnam - APPCB, labeled Satisfactory. 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 19.0 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 4.0. 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 18.0 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.
