Multivariate Analysis

Exposure to air pollutants like PM2.5 can harm human health. A study in Tehran in 2018 looked at how meteorological factors like wind speed, precipitation, humidity, and temperature affect PM2.5 levels. The researchers found that in summer, wind speed had a significant impact on PM2.5 levels, with higher wind speeds leading to lower PM2.5 concentrations. Overall, meteorological factors could explain around 20-47% of the changes in PM2.5 levels in different seasons. Since Tehran's PM2.5 levels exceed national standards, more efforts are needed to improve air quality in the city.
