Persons are medically considered to have lead poisoning if they have a concentration greater than `10` micrograms of lead per decilitre of blood. What is the concentration in parts per billion?

A

`1000`

B

`100`

C

`10`

D

`1`

Text Solution

Verified by Experts

The correct Answer is:
B
`10mug` per decilitre
`rArr10xx10^(-6)g` in `100 mL`
`therefore 10^(9)` parts (`1` billion)has `=(10xx10^(-6))/(100)xx10^(9)g=100g`
