A) \[20\mu g/100\,mL\]
B) \[30\mu g/100\,mL\]
C) \[4-6\mu g/100\,mL\]
D) \[10\mu g/100\,mL\]
Correct Answer: B
Solution :
The concentration of lead in blood averages about\[25\mu g/100mL\]. Increase to\[70\mu g/100mL\]is generally associated with clinical symptoms. Hence, a level of \[30\mu g/100mL\]is considered alarming. The chief sources of Pb in water are the effluents of lead and lead processing industries.You need to login to perform this action.
