Twenty-five years after 9/11, the health effects of the World Trade Center response are still being uncovered, with new research suggesting that everyday exposure to heat and air pollution may add to the long-term burden faced by responders.
Researchers at the Icahn School of Medicine at Mount Sinai analysed data from 18,734 World Trade Center Health Program responders living in New York City. The study examined later-life exposure to fine particulate matter, known as PM2.5, temperature, and neighbourhood greenery, and how those exposures were associated with frailty, PTSD, and depression.
