Early 'Forever Chemicals' Exposure Could Impact Economic Success in Adulthood, Study Says

Early life exposure to toxic PFAS "forever chemicals" could impact economic success in adulthood, new first-of-its-kind research [PDF] suggests. From a report: The Iowa State University and US Census Bureau working paper compared the earnings, college graduation rates, and birth weights of two groups of children -- those raised around military installations that had firefighting training areas, and those who lived near bases with no fire training site. The military began using PFAS-laden firefighting foam in the early 1970s, which frequently contaminated the drinking water supplies in and around bases. Those who lived in regions with firefighting training areas earned about 1.7% on average less later in life, and showed a graduation rate about 1% lower. Those born between 1981-1988 earned about $1bn less in today's earnings, or about $1,000 a person on average, compared to those who did not live near the firefighting training sites. The data also shows lower birth weights among the population -- a factor linked to lower economic success later in life. The findings "highlight the importance of careful scrutiny of novel chemicals," said Irene Jacz, a study co-author and Iowa State economist. "We think that there's a causal effect from PFAS here but it's really hard to say, 'Oh it's all brain chemistry, or health effects' so there's a need for more research" Jacz said. The paper is not yet peer-reviewed, but will soon go through the process.
