National Academies Press 2005 260 pages $42.00 Paperback TD427 At present more than 11 million people in the US have percholate in their drinking water drinking water supply of water available to animals for drinking supplied via nipples, in troughs, dams, ponds and larger natural water sources; an insufficient supply leads to dehydration; it can be the source of infection, e.g. leptospirosis, salmonellosis, or of poisoning, e.g. at a concentration of at least four parts per billion. Authorities have not determines a safe standard for percholate but a contingent of federal agencies asked the National Research Council to assess the adverse health effects of percholate injection from clinical, toxicological and public health perspectives.
