water For water, the oral LD50 is greater than 90 mL/kg. In this particular case, it means that they failed to reach a dose of water that killed half their rats, and are calculating based on the highest dose that they were able to give to rats. That means, that if you give a rat 90 mL of water/kg of rat into their stomach, less than 50% of them will die. If you translate this into a human (where the numbers won't be exactly the same, but will be fairly similar), you can give a little over 6L of water to a 150 lb human before 50% of them will die (6 L is about 1.5 gallons). Or around 13.5 lbs of water. That's a lot of water. ´ÙÀÌ¿Á½Å Guinea pigs have a LD for TCDD in food of only 0.0006 mg/kg (that is, 0.0006 mg of TCDD per kg body weight). In comparison, rats have a LD50 for TCDD in food of 0.022-0.045 mg/kg, while hamsters have a LD50 of 1 mg/kg. Clearly, TCDD is a highly toxic chemical, although species vary greatly in sensitivity. |
