Is PM2.5 of 13.0 harmful?

PM2.5 level is 13.0 µg/m³, considered 'Good'. Fine particulate matter can penetrate deep into lungs and cause respiratory issues. People with asthma or heart disease should take precautions.

Should I worry about NO₂ being 0.1 µg/m³?

NO₂ level is 0.1 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 3.4 mg/m³?

Carbon Monoxide is at 3.4 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 19.2 µg/m³. Though protective high up, it can cause respiratory problems when present in lower atmosphere, especially in sunlight-heavy hours.

📖 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 Sebastopol 103 Morris Street Air Quality

The AQI at Sebastopol 103 Morris Street is 19, classified as Good. Air quality is healthy and safe for all.

PM2.5 at this station is 13.0, 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.

Carbon Monoxide is measured at 3.4 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 19.2. 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 0.1 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.
