6/12/1988· Since the LD/50 for calcium disodium EDTA (the chelate employed) is 10 millimoles per kg, this is 2.9 gm/kg. A 30 kg child (66 pounds) would need to consume and retain 90 gm of EDTA to be poisoned. This would be the equivalent of drinking 30,000 gallons of water at one sitting with 0.7 ppm EDTA present in the water.
