Abstract:
Flat breads such as Lavash, Barbari, Taftoon and Sangak bread are mainly produced from soft white wheat flours in Iran. Bread samples were collected from Tehran city and analyzed by flame atomic absorption spectrophotometry for three potentially hazardous heavy metals, Lead (Pb), Cadmium (Cd) and Nickel (Ni). The mean concentrations of Pb levels in Lavash, Barbari, Taftoon and Sangak breads were 0.42, 0.27, 0.38 and 0.52 mg kg-1 dry weight, respectively. Also, the mean concentrations of Cd levels at these breads were 0.65, 0.42, 0.12 and 0.50 mg kg-1 dry weight, respectively. The mean concentrations of Ni were 0.45, 0.47, 2.67 and 0.96 mg kg-1 dry weight, respectively. The high levels of daily intake of Pb, Cd and Ni, may cause public health problems, especially the high Cd level in Lavash and Ni in Taftoon breads. Monitoring heavy metals is imperative during wheat production, storage, mill flour and baking bread for reduction of public health concerns.
