Susanne Rust of the Los Angeles Times reports (paywalled) that industry executives knew for decades that microplastics were infiltrating the human body. Slashdot reader joshuark shares an excerpt from the report: Scientists today say we're just beginning to understand the harm that the tiny bits of plastic we drink, eat and breathe are doing to the human body. Internal memos among company scientists and executives obtained by The Times reveal that for at least half a century, the plastics industry has been aware of and concerned about the potential for microplastic contamination in the human body. But recently discovered chemical company documents dating back several decades show that industry scientists have long been aware of -- and concerned about -- the way microplastic particles migrate beyond the gut in animals and humans, depositing in important organs. And the potential for that knowledge to affect the plastic food packaging industry.
Their concern goes back to 1974 and a scientific meeting at a New York City hotel, where a German gastroenterologist presented a scientific paper that showed for the first time that ingested particles like microplastics could infiltrate the rest of the body. His presentation was largely overlooked by the government scientists in attendance but became a point of worried discussion among company scientists. Tracey Woodruff, professor of epidemiology and population health at Stanford University, who reviewed the documents, said they indicate scientists and executives at major chemical companies have known and remained silent even as microplastics accumulated in tissues. She likened it to other industries that knew about pollutants -- greenhouse gases, asbestos and tobacco -- but did not take action to make them safer.
A spokesperson with the chemical industry's largest trade group took issue with that characterization. "Scientific debate over what the evidence shows is not silence. It is how sound science and effective policy advance," said Craig Davis, senior director of plastics chemistry at the American Chemistry Council. "Our industry is committed to advancing microplastics science by supporting independent research and policies that would do so."
