Professor David Hennessy published in the most recent issue of Science of the Total Environment. Hennessy co-authored the article "Health burden associated with tillage-related PM2.5 pollution in the United States, and mitigation strategies" with Ashish Pokharel and Felicia Wu of Michigan State University. The article estimates the annual deaths and disability-adjusted life years (DALYs) from CVD and COPD attributable to PM2.5 emissions from corn, soybean, cotton, and wheat tillage in the contiguous United States. The authors estimate that approximately 1000 annual deaths and 22,000 DALYs from CVD, as well as 300 annual deaths and 7400 DALYs from COPD, were attributable to tillage-related PM2.5 emissions. Tillage related primary PM2.5 emissions contribute about 0.002 % of total CVD and COPD deaths in the United States, and its related health economic value loss is about 12.9 billion USD annually.
