Surface ozone, particulate matter, and mercury are well-known pollutants affecting public health and welfare. They are the target of air quality regulations in most of the developed world. Environmental agencies typically rely on domestic emission controls to meet air quality goals. However, such efforts may be compromised by pollution transport on a global scale. I will discuss the evidence for this global transport of pollution, the mechanisms involved, and the implications for policy.
