Bo Y, Guo C, Lin C, et al. - Researchers explored the impact of air quality improvement on health in a cohort of nearly 135,000 adults between 2001 and 2014. They used an extensive longitudinal cohort to determine dynamic shifts in long-term exposure to ambient particulate matter (PM_2.5) and incidence of hypertension. Specifically, they examined the links between change in long-term exposure to PM_2.5 and the development of hypertension. In 2002, 2003, and 2004, a rise in PM_2.5 concentrations was reported, which began to abate in 2005. A decreased incidence of hypertension was reported in relation to an improvement in PM_2.5 exposure. In order to attenuate cardiovascular disease risk, air pollution mitigation represents an effective strategy, according to the researchers.
