As many as 31 pesticides with a value running into billions of pounds could have been banned because of potential health risks, if a blocked EU paper on hormone-mimicking chemicals had been acted upon. The science paper, seen by the Guardian, recommends ways of identifying and categorising the endocrine-disrupting chemicals (EDCs) that scientists link to a rise in foetal abnormalities, genital mutations, infertility, and adverse health effects ranging from cancer to IQ loss. Commission sources say that the paper was buried by top EU officials under pressure from big chemical firms which use EDCs in toiletries, plastics and cosmetics, despite an annual health cost that studies peg at hundreds of millions of euros. The unpublished EU paper ... was supposed to have enabled EU bans of hazardous substances to take place last year. Under pressure from major chemical industry players, such as Bayer and BASF, the criteria were blocked. In their place, less stringent options emerged. Last month, 11 MEPs complained in a cross-party letter to the health and food safety commissioner, Vytenis Andriukaitis, about the EU's failure to honour its mandate and adopt the EDC criteria. This was supposed to have happened by the end of 2013. In place of the proposed identification of hormone-mimicking compounds, the EU's current roadmap favours industry-supported options for potency-based measurements of EDCs. These would set thresholds, below which exposure to low-potency EDCs would be deemed safe.
