Air quality in Setúbal, Portugal was studied over 10 years to see how pollution levels changed. Pollutants like PM10, PM2.5, O3, NO, NO2, and NOx were measured in different areas. The air quality got better over time, except for O3. Levels of PM10, O3, and nitrogen oxides were still too high. Traffic, industry, and wood burning were the main sources of pollution. Measures are needed to reduce their impact on air quality.
