Long term diabetes effect of penta-BDE in mice. Mice exposed to DE-71 (mainly penta-BDE) only via their mothers (in the womb and during lactation) showed markers of diabetes later as adults. The mothers were given PBDEs at 0.1 or 0.4 mg per day / kg body weight (considered comparable to human environmental exposure). Media coverage refers to PBDEs but the substance tested, penta-BDE, was banned worldwide by the Stockholm Convention in 2009
