A University of Arizona study published in Environmental Research found that extreme heat exacerbates the impacts of toxins on the kidneys.
Researchers from the U of A Mel and Enid Zuckerman College of Public Health followed 77 farmworkers in Sonora, Mexico, testing their blood and urine over several months. The average age of the workers was 29 years old.
“For arsenic, cadmium, chromium and uranium, when those were combined with heat – so when the workers’ bodies were heated up – we saw worse effects on the kidneys,” said Postdoctoral fellow Rietta Wagoner.
Wagoner noted that heat changes the body’s response to chemicals in several ways, making exposures more dangerous.
