Queensland chief health officer Dr Jeannette Young is calling for an increase in the number of children having their lead levels tested in the north-west mining city of Mount Isa.
In 2008, 400 children were tested for exposure to lead, with 11 per cent having elevated levels and some so high they had ongoing developmental issues.
Dr Young wants children under the age of five who undergo a blood test at the Mount Isa Hospital to have the option of checking their lead levels at the same time.
