Indeks Kualitas Udara (AQI) utama yang ditampilkan di atas dihitung menggunakan rumus Interpolasi Linear EPA AS berdasarkan konsentrasi PM2.5 (Partikel Halus).
- PM2.5 Saat Ini: 26.75 µg/m³
- Perhitungan: Kota Anda termasuk dalam kategori "Sedang" (Kategori 2).
Catatan: Meskipun beberapa polutan (O3, NO2, SO2) dipantau, PM2.5 digunakan sebagai "penggerak" utama untuk nilai indeks karena biasanya mewakili risiko kesehatan tertinggi.
Pertanyaan yang Sering Diajukan
