From the 1960s to the 1980s, the use of lead in fuel, paints, and pipes caused widespread contamination.
Chiba UniversityDec 6 2024 It is estimated that 170 million Americans alive today were exposed to high lead levels as children, which caused significant harm, including a measurable drop in IQ scores. While we now understand the dangers of these chemicals, large sections of the population are still exposed to them.
"There is a growing need for non-targeted chemical analysis to detect new or previously unrecognized substances that are not covered by current targeted analyses," says Dr. Eguchi, emphasizing the need for broader analytical approaches. Using this method, the researchers analyzed serum samples from 84 pregnant women at 32 weeks of pregnancy. These samples were then examined using Liquid Chromatography-Quadrupole Time-of-Flight Mass Spectrometry. The detected chemicals were classified based on their origin using the PubChemLite for Exposomics database, which contains information on over 371,663 chemicals.
