The rapid development of electronic devices has led to the issue of improper disposal of electronic devices. E-waste can have many severe influences on both the environment and human beings. To better understand the knowledge of e-waste and air quality, this research evaluated the level of PM2.5 and PM10 to determine the impact of e-waste-related activities on air quality in Guiyu, China, and suggested policy recommendations based on the analysis results. In this research, we explored the relationship between e-waste and air quality through the lens of laws and regulations. The analysis used air quality and climate variables, including temperature, humidity, air pressure, precipitation, ground wind speed, and wind direction data. We reviewed selected national, provincial, and municipal laws and regulations. The research compared the existing air quality with the COVID-19 period to reflect the trends, and developed policy and management recommendations to improve the air quality in the region. The pollution rose diagram, and the HYSPLIT model were used to analyze pollution dispersion and interpret the results. We find that mean PM2.5 levels significantly decreased over the COVID-19 period, showing that the closure of e-waste-related activities in Guiyu as a result of rigorous laws had a significant positive influence on local air quality. This highlights the value of strict rules in reducing the impact of human activities on local air quality.
