Solution
The correct option is C Lead
Lead (Pb) is released as an air pollutant by combustion of petrol, as tetraethyl lead is used as antiknock in petrol. This lead is very harmful and causes lead poisoning, which disturbs the nervous system, liver, kidneys in adults and also causes brain damage in children. About 150 to 400 mg of lead is stored in the body of an average adult and blood levels average about 25 mg/100 ml. Increase to 70 mg/100 ml of blood is generally associated with clinical symptoms.
