Abstract

Air pollution is one of the major challenges for human development, directly threatening human health. The study presents the air quality assessment of Bac Ninh province based on the integration of the Geographic Information System (GIS) and the Air Quality Index (AQI). The data used for this study are the parameters affecting the air environment, including Total suspended particles (TSP), Sulfur dioxide (SO2), Carbon monoxide (CO), Nitrogen dioxide (NO2), which are collected from 52 monitoring stations in Bac Ninh province in 2019. The results show that the air quality of Bac Ninh province is heavily polluted and divided into four levels, namely medium, poor, bad, and very bad. Areas with bad and very bad air quality are mainly distributed in cities, towns, and areas with many factories, and craft villages such as Tu Son town, Bac Ninh city, and Que Vo district.
