Investigating the concentration of toxic metals (arsenic, cadmium, and lead) in wheat and wheat flour in Golestan and Mazandaran provinces

The objective of this study was to measure the amount of heavy metals cadmium, lead and arsenic between the amounts of metals and the risk assessment in wheat, extracted flax from imported wheat and indigenous cultivars. Considering the wheat cultivar and the number of flour mill factories in Golestan and Mazandaran provinces. Wheat samples were harvested. Samples after flint transfer to flour mills and process of flour process for evaluation and determination of heavy metals in laboratory. Research Institute of Science and Technology Research Institute. The results of this study showed that the highest concentration of cadmium in wheat flour samples in 2017 and 2018 was related to the R sample. The highest concentration of lead in wheat flour samples is related to the R sample. The highest concentration of arsenic in wheat flour samples is related to the N sample. According to the results obtained in wheat samples, the mean values ​​of cadmium in B sample were the highest. The mean of lead values ​​in the W sample was the highest. The concentration of arsenic in A sample is also the highest. The results showed that S, M, N, K, R, D, and E samples were unsafe for adult samples in flour samples. Also, R sample flour for adults was unsafe for cadmium. The F, H and M specimens were safe in adults in terms of heavy metals. In samples of wheat, S, N, and H samples were unsafe for adults in terms of lead levels.
