Iwant to measure the amount of Lead Pb in a soil sample ?
I have done all the digestion calculation and procedures and Iused only 2 grams of soil .
The instrument data gave me the following concentrations:
Sample of soil 1= 2.06 ug/L
Sample of soil 2= -1.18 ug/L
So how much Lead in one gram of soil?
How I know if it's high and above the limit of allowedconimination !?
