WAKEFIELD – Greenpeace will slam Nike, adidas and Puma in a new report to be released next week after the campaign group found trace amounts of potentially hazardous chemicals in World Cup 2014 soccer merchandise. The study, which tested thirty-three products including football boots, shirts and goalkeepers gloves, found concentrations of PFOA in some products above EU regulatory limits, and for the first time sampled items for DMF – a chemical used in the synthetic leather making industry.
