Liver health

Air pollution and liver health research uncovers how environmental pollutants affect this vital organ's function, with implications extending far beyond respiratory health. Studies demonstrate that particulate matter and other air pollutants can reach the liver through the bloodstream, contributing to inflammation, oxidative stress, and metabolic dysfunction. The evidence reveals connections between air pollution exposure and fatty liver disease, hepatitis progression, and other liver conditions. Discover the latest research showing how air quality affects liver function and what this means for metabolic health and disease prevention.
  • In Sydney - Mice were exposed to 10μg of traffic-derived PM2.5 particles (roughly what humans are exposed to in Sydney) and the effects of this on their liver health was measured at four, eight and 12 weeks (Day, 2025)
    • At 4 weeks, not much change
    • At 8 weeks, disruption to the normal metabolic function of the liver
    • At 12 weeks, significant change
  • When we inhale air pollution, PM2.5 enters the bloodstream through the lungs. The liver, which filters toxins from the blood, then accumulates these substances, which can include heavy metals such as arsenic, lead, nickel and zinc (Day, 2025)
