Today we review research into the impact of exposure to PM2.5 had on anxiety for a large group of older women (mean age 70) over various periods of exposure. Anxiety disorders affect 16% of people worldwide over their lives and 11% have suffered from it in the last year. Results indicate a clear link with 12% more of those exposed to fine particulates showing high anxiety symptoms than those who were not so exposed. Also those who live between 50 and 200 m of busy roadways with traffic-related air pollution were more likely to show these symptoms than those who live farther away. Exposure to larger sized particulates (such as PM10) and exposure within 50 m of roadways did not show greater anxiety symptoms. Because of the people sampled in this study, it is not possible to extend these results to younger women or to men although there is evidence of pollution-stress links for the latter group.
