Studies of chemicals in our blood typically capture only a small and unknown fraction of the entire chemical universe. Now, a new approach aims to change that.
American Association for the Advancement of Science Oct 18 2024 In a study involving blood samples of pregnant women collected between 2006 and 2008, researchers report having quantified many complex mixtures of chemicals that may pose neurotoxic risks, even when the individual chemicals were present at seemingly harmless levels.
The toxic exposome has become particularly concerning as rising chemical production has been linked to an increase in disease and developmental disorders, especially in children exposed to endocrine-disrupting and neurotoxic substances. Although human biomonitoring studies aim to measure the chemical burden in biological samples like blood and urine, they often focus on a limited set of known chemicals and overlook the complexity and variability of the entire toxic exposome.
