A months-long investigation by EHN revealed that scientists who have criticized plans in Europe to regulate hormone-disrupting chemicals have past or current financial ties to regulated industries. The stakes are high in the controversy because it involves the European Union’s strategy to regulate these chemicals – the first attempt in the world to do so. The new rules would have sweeping, global ramifications for companies that manufacture or use high-volume substances such as bisphenol A. The investigation showed that the scientists (all editors of science journals) who attacked the EU plan have collaborated with chemical, pharmaceutical, cosmetic, tobacco, pesticide or biotechnology companies.
