This module will explore the health effects of air pollution from the definition of adverse health effect to the main pathways of exposure and diseases. It will describe the main pathological mechanisms exerted by air pollution in harming the body and will differentiate short- and long-term effects. It will also highlight the populations at higher risks from the negative effects of air pollution exposure.

By the end of this module, you will:

• describe how air pollutants enter the body;
• outline the main pathological mechanisms leading to disease;
• differentiate between short- and long-term health effects of air pollution;
• recognize populations at higher risk.
