Evalution Of Estimated Daily Intake (EDI) Of Lead For Wheat (Durum) In Khuzestan Province, Iran

The excessive amounts of lead in food chain can cause health problems for humans and ecosystem. Wheat is one of the most consumed cereal grains worldwide and makes up a substantial part of the human diet. A total of 100 wheat seed samples were collected from Wheat fields, the wheat farms were near maturity. In the samples Lead concentration was measured. The results showed that average concentrations of lead in wheat seeds was 43.53 μg/kg. 8% of wheat seed samples had lead concentrations above 150 μg/kg (i.e. Guide value for lead). The dietary intakes for lead in the local population ranged from 0.01 to 5.06 μg/day kg bw. The estimated daily intakes of lead by the local population was 0.38 μg/day kg bw, which corresponds to 10.5% of the tolerable daily intakes (i.e. 3.6 μg/day kg bw). Three out of 100 samples (3%) exceed the tolerable lead daily intakes (i.e. 3.6 μg/day kg bw). As a whole, long term consumption of the local wheat may bear high risk of heavy metal exposure to the consumer in the study region. Keywords- Lead, EDI, Wheat, Khuzestan
