In the present study, the levels and probable public health risks of selected metals (Fe, Mn, Cu, Zn, Ni, Cd and Pb) in nine wheat flour samples collected from Amhara, Oromia, South region, and the Strategic Food Reserve Agency were determined using FAAS and compared with results of prior studies and critical level. The wet digestion method using 65 % HNO3 and 72 % HClO4 in 300°C for 3 h was used when preparing the sample. Validation of the optimised digestion method was assessed using the spiking method, and an acceptable percent recovery from all metals. The levels of Fe, Cu, Mn, Zn, Ni and Cd ranged between 8⋅5297 and 11⋅1535, 1⋅633 and 4⋅2346, 3⋅1875 and 8⋅5313, 2⋅3589 and 2⋅7719, 0⋅154 and 0⋅854, and 0⋅0411 and 0⋅216 mg/kg, respectively, for Ethiopian wheat flour, while the level of Fe, Cu, Mn, Zn, Ni, Cd and Pb were ranged between 8⋅0099 and 8⋅1089, 1⋅663 and 1⋅6691, 4⋅5625 and 4⋅6250, 2⋅3015 and 2⋅3072, 0⋅9423 and 1⋅1346, 0⋅1593 and 0⋅1606, and 0⋅13 and 0⋅1381 mg/kg, respectively, for imported wheat flour. However, Pb had a concentration of less than 0⋅043 mg/kg for Ethiopian wheat flour. Findings indicate that Ethiopian wheat is comparatively higher in Fe, Mn, Cu, Zn and Cd, but lower in Ni and Pb than imports. From the result of the study, it can be concluded that the level of heavy metals determined in this study was within the permissible limit, and no probable health risk because both the Hazard quotient (HQ) and the Hazard Index (HI) are found to be below 1⋅0 regarding study metals.

“…THQ of each toxic metal was calculated with the following formula (Chien et al 2002): If the THQ coefficients would higher than 1, that means potential non-carcinogenic health effects may be seen. If the THQ coefficient would lower than 1, that means no potential non-carcinogenic health effects may be seen (Çulha et al 2016, Mehmood et al 2020, Töre et al 2021.…”

In this research, “diatoms” as the first step and “fishes” as the last step of the food chain were compared as the toxic metal accumulation bioindicator in an A Class wetland in Turkey. Toxicant bioaccumulations were determined in liver, gill and muscle tissues of 2 commercially consumed fish species "Carassius gibelio" and "Cyyprinus carpio" and in frustules of epiphytic diatom communities living on submerged macrophytes. Samples were collected from the Gala Lake, which is among the best stopover habitats of birds migrating between Europe and Africa, seasonally considering the paddy harvest period, which is a major stress factor for the ecosystem. Also potential human health risks associated with the consumption of fishes and consumption – dermal contact of diatoms were evaluated both for summer – before paddy harvest (BPH) and autumn – after paddy harvest (APH) periods. As a result of this research, the investigated toxic metal bioaccumulation levels were increased significantly in diatoms in the APH period, while less significant exchanges were recorded in fish tissues, in general. The data showed that the diatoms are much more sensitive to changes in the environmental conditions than fishes and they are more effective biological tools as toxic metal accumulation bioindicators than fishes.

Bu nedenle balıklarda biriken ve insan sağlığını da olumsuz etkileyen ağır metallerin izlenmesi ve kontrolü günümüzde oldukça önemli ve elzem görünmektedir (Tore et al, 2021).…”

Atatürk Dam Lake, which was established on the Euphrates River for agricultural irrigation and electricity production, is the largest dam lake in Turkey. Many fish species, which are the primary food source for humans, live in the dam lake. Therefore, possible pollution in this dam will adversely affect not only fish but also human health. For this purpose, in this study, lead, cadmium, chromium, iron, zinc, and copper levels were measured in the liver, gill, and muscle tissues of Cyprinus carpio, which was the food source of the local people, caught from two different regions (Sitilce and Samsat) of the dam lake in August and September in 2021. In our study, lead was not detected in any of the tissues and cadmium was not detected in gill and muscle tissues in fish from both regions. It was found that the levels of all metals found in the fish of the Sitilce region were not statistically different from the fish of the Samsat region (except the liver iron level). Our research results showed that the heavy metal levels in the muscle tissue of C. carpio were below the legally permissible limits in terms of nutritional safety and human consumption. In addition, when compared with previous studies, it was determined that there was a decrease in heavy metal levels in the tissues of fish after the wastewater treatment plants were established.
