More than half of human ashes are now collected after cremation according to one crematorium worker interviewed on Radio 4 on 12-3-12. But do those collecting the remains of their loved ones realise the ashes are toxic? What do people do with the ashes? If they scatter them in the wind, is there a chance that they will inhale the dust and rapidly join their recently dear departed? Or if they pile them up around the roots of Gramdma’s favourite old English rose bush, is it possible that the flowers will wilt and drop off? What exactly is it safe to do with the ashes so lovingly collected?
