# Detection limits

I am given this question:

A study showed that over 2000 children in China have been poisoned by lead. Blood samples have been taken and show that there is 10 times as much as the acceptable amount of lead in their blood. How can you analys the lead in their blood?

How do I determine which of the following analytical methods is most suitable: ICP, FAAS, GFAAS and ICP-MS.

• Presumably your [$H^+$] really a difference in concentration (also probably multiplied by some negative power of 10) with respect to some initial condition as a negative concentration does not make sense? – porphyrin Apr 14 '18 at 14:50
• If you have considerably less than 30 ng/ml of Al in your sample, you won't find it with flame atomic absorption spectroscopy. Is that what you want to know? Otherwise please elaborate on your actual problem. – Karl May 20 '18 at 12:23
• I will edit my question and elaborate on an actual problem where the table has to be used :) @Karl – J.Se May 20 '18 at 12:31
