Question
B) assuming the toxicity is the same in a human, how much BHT would have to be eaten by students who all have masses of 50.0 kg, to kill half of the class? C) does BHT seek to be highly toxic or mildly toxic based on your answer to A and B? 1) The solvent in this lab is BHT. LDso is the Lethal Dose and is defined as the amount of chemical given to a population of test animals necessary to kill 50% of the animals. It is reported as a ratio of chemical mass/animal body mass. A) What is the LDso of BHT orally in mice? B) Assuming the toxicity is the same in a human, how much BHT would have to be eaten by students who all have masses of 50.0 kg, to kill half of the class? c) Does BHT seem to be highly toxic or mildly toxic based on your answer to A and B2Explanation / Answer
BHT is used as an antioxidant because of its ability to function as a radical scavenger.
A) LD50 of BHT orally in mice is 2000 mg/kg
B) When we assume the toxicity is the same in a human. then the LD50 of BHT = 2000 mg/kg
The BHT would have to be eaten by students who all have masses of 50.0 kg, to kill half of the class is:
50 x 2000 mg = 100000 mg = 100g
C) In general, the smaller the LD50 value, the more toxic the chemical is.
From the answers A and B we can say that BHT seems to be mildly toxic.
