Researchers at NIEHS, led by Dana Barr, M.D., are analyzing levels of harmful chemicals in environmental and human samples. Their goal is to understand how multiple chemical exposures interact and impact human health. Barr, a leading expert in exposure assessment, specializes in biomarkers—measuring specific chemical levels in blood or urine. This research aims to identify links between toxic chemical mixtures and chronic diseases. Ultimately, these findings help inform public health policies and interventions to better protect communities from environmental health risks.
