FRIEDRICHSHAFEN - Greenpeace will this week make public controversial findings from investigations in which the environmental action group claims to have found "significantly higher" concentrations of certain perflourinated chemicals (PFCs) in the indoor air of stores selling outdoor gear compared to the air from offices or clothing stores not selling outdoor products. PFCs in what Greenpeace describes as "significant concentrations" were found in the flagship stores of several international outdoor brands in stores in Germany and Italy.
