Indeks Kualiti Udara (AQI) utama yang ditunjukkan di atas dikira menggunakan formula Interpolasi Linear EPA AS berdasarkan kepekatan PM2.5 (Jirim Zarah Halus).
- PM2.5 Semasa: 44.75 µg/m³
- Pengiraan: Bandar anda berada dalam kategori "Tidak Sihat (Sensitif)" (Kategori 3).
Nota: Walaupun beberapa bahan pencemar (O3, NO2, SO2) dipantau, PM2.5 digunakan sebagai "pemandu" utama untuk nilai indeks utama kerana ia biasanya mewakili risiko kesihatan tertinggi.
