11. Some sources quote the median lethal dose ( for an average 75 kg opiate-naive individual ) as being between 75 and 600 mg. 12. The median lethal dose ( LD 50 ) of epibatidine lies between 1.46 �g / kg and 13.98 �g / kg. 13. Rats treated with a single injection of niobium pentachloride or niobates show a median lethal dose ( LD 50 ) between 10 and 100 mg / kg. 14. The strength of venom differs markedly between species and even more so between families, as measured by median lethal dose ( LD 50 ) in mice. 15. The median lethal dose ( LD 50 ) of soluble palladium compounds in mice is 200 mg / kg for oral and 5 mg / kg for intravenous administration. 16. The median lethal dose ( LD 50 ) is 244 mg / kg in mice, 50 70 mg / kg in rabbits, and 30 50 mg / kg in humans. 17. Sarin has a median lethal dose ( LD 50 ) of 5 mg ( for a 70 kg human ), while GF has an LD 50 of 1.2 mg. 18. The median lethal dose ( LD 50 ) for oral intake in rats is 260 mg per kg of body weight and it is 3.6 g / kg for dermal intake. 19. For example, the oral median lethal dose ( LD 50 ) for rats for calcium carbonate and calcium chloride are 6.45 and 1.4 g / kg, respectively. 20. Its median lethal dose ( LD 50 ) in mice is 0.1 mg / kg ( intravenously ) . 0.071 mg / kg ( IV ) has also been reported.
