I know I always think of cadmium pollution when I hear "human sludge". Can anyone enlighten me as to how heavy metals get into human waste in sufficient quantities to be dangerous?
It's caused by industry dumping as opposed to humans consuming. Here in Indpls we have oxygen furnaces to burn off the cake because of the heavy metals.
