Nghiên cứu sự biến đổi chất lượng không khí theo mùa tại tỉnh Hưng Yên

Abstract

Hung Yen is the province in the key economic triangle of  Northern Vietnam, serves as a political, economic, cultural, and security hub. This region hosts large industrial zones and traditional craft villages, contributing to significant air pollution challenges despite economic achievements. This study investigates the seasonal variations in air quality three representative areas: urban, industrial, and craft villages in Hung Yen. Methods used in the study include monitoring, laboratory analysis and visualization. The parameters TSP, SO₂, NO₂, CO and O₃ were monitored in January and April 2024. Then, QGIS software was used to simulate data visualization. The results showed that the concentration of pollutants, especially TSP, reached the highest level in Minh Khai craft village in April, exceeding QCVN 05:2023/BTNMT (1.57 times), while other pollutants remained within safe limits. This research enhances the understanding of air pollution dynamics through seasonal assessment and spatial mapping, providing a foundation for informed environmental management strategies in Hung Yen.
