A) \[\text{20}\mu g/100\,\,ml\]
B) \[30\mu g/100\,\,ml\]
C) \[4-6\mu g/100\,\,ml\]
D) \[10\mu g/100\,\,ml\]
Correct Answer: B
Solution :
[B] 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. |
