Abstract

Background: Wheat is one of the agricultural products cultivated in many parts of the world and is an essential and significant component of the diet of people around the world. This study aimed was to evaluate heavy metals in wheat farms in the north of Ahvaz in 2020.

Methods: This research was conducted in two areas of Weiss and Arab Asad located in the north of Karun catchment area located in the north of Ahvaz city. Twelve samples of wheat plants in each area were randomly sampled from each farm during harvest. Chemical digestion was performed by a wet method, and heavy metals were measured by ICP model Varian 710-ES.

Results: The highest amounts of heavy metals in wheat of Weiss and Arab Assad regions were 58.17 and 58.42 mg/Kg of iron, respectively. Chromium had the lowest concentrations among heavy metals in wheat of Weiss and Arab Assad farms at 1.07 and 1.14 mg/Kg, respectively. The highest hazard quotient (HQ) of heavy metals in wheat in the age group of children was related to manganese metal (13.51). The lowest value of heavy metal HQ for wheat consumption for children was obtained for cobalt metal (0.21).

Conclusions: According to the results, it seems that wheat consumption is dangerous for the health of different age groups in terms of manganese metal. In general, the results of heavy metal health risk assessment in wheat samples showed that consumption of this product could have an acute detrimental effect on consumer health.
