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?

Text Solution

Verified by Experts

`10^(-1)` litre blood has `10xx10^(-6) g Pb`
`10^(9)` litre blood has `(10xx10^(-6)xx10^(9))/(10^(-1))=10^(5)ppb`
