A 1-year-old boy whose mother saw something powdery and gray on his shirt discovered he had eaten some of the ashes from her deceased father’s cremation. Quoted from a previous interview, Rolf Halden, a professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools and director of the Center for Environmental Health Engineering at ASU’s Biodesign Institute, says cremation mineralizes the body and produces ashes that contain carbon but are not a serious health threat, unless the deceased’s teeth contained heavy metals. Learning her son was safe, the mother says she laughed about this incident, because her father “definitely would have wanted me to laugh about it.”
