AIR pollution, known to affect lung health, has now been linked to a higher risk of kidney disease.
Scientists from Peking University in China compared the prevalence of the condition among 47,204 adults with air pollution data. They found that cases of kidney disease were highest in the most polluted urban areas.
It’s thought that tiny particles of pollution, known as particulates, may trigger an inflammatory response in the airways that moves to other parts of the body, including the kidneys.
Writing in the Journal of the American Society of Nephrology, the scientists say further investigation is needed. Their work follows similar findings from a 2020 US study.
