Investigative journalist Mariah Blake's book, "Die Vergiftung der Welt," details the alarming extent to which PFAS chemicals have infiltrated global environments and the deceptive practices of the chemical industry. Blake meticulously weaves together historical context, scientific evidence, and personal stories, highlighting the decades-long marketing of these "forever chemicals" by corporations like 3M and DuPont, despite prior knowledge of their carcinogenic links. The book focuses on the small town of Hoosick Falls, New York, where residents like Michael Hickey and Emily Marpe fought for years against PFAS contamination in their drinking water, stemming from local manufacturing plants. Blake's research, based on over 600 interviews and extensive document review, exposes the power of the US chemical lobby and the failure of regulatory bodies to protect citizens, while also noting the significant financial burden of remediation efforts, estimated at €800 million annually in Germany alone.
