Exposure to formaldehyde at work linked to cognitive problems later

A variety of jobs expose people to formaldehyde, a strong-smelling gas used in manufacturing wood and chemical products, plastics and in other applications. A new study suggests that long-term exposure to formaldehyde during work may be associated with cognitive impairment later on. The research is published in the December 22, 2021, online issue of Neurology, the medical journal of the American Academy of Neurology.
