Health Concerns Related to Consumption of Fish from Anzali Wetland
Bibliographic record
Abstract
Two hundred and forty fishes including Hypophthalmichthys molitrix , Silurus glanis , and Esox lucius (male and female) were collected from four sampling sites in Anzali wetland including Anzali, Khazarvila, Pirbazar, and Beshman through late April 2011. The potential health risk of Pb, Sn, and Zn to consumers was assessed by calculating the estimated daily intake, estimated weekly intake, hazard quotient, maximum allowable fish consumption rate, and monthly allowable consumption rate. In addition, the tissue structure of liver was studied in fish. Concentrations of Pb, Sn, Zn, Hg, Cu, and Ni were also measured in water and sediment. Based on the results, the accumulation and distribution patterns of metals in fish from different stations were as follows: Zn > Sn > Pb, H . molitrix < S. glanis ≤ E. lucius , and Khazarvila < Beshman ≤ Pirbazar ≤ Anzali, respectively. The distribution of metals in water and sediment showed the following pattern: Zn > Cu > Hg > Sn > Ni > Pb. Liver samples had a normal histological structure consisted of intersinusoidal hepatocyte cords and hepatic triad in all fish species collected from Pirbazar, Beshman, and Khazarvila stations. In contrast, tissue changes including melanomacrophage aggregations and hemorrhage were detected in S. glanis and E. lucius collected from Anzali station. In sum, the levels of permissible tolerable daily intake and permissible tolerable weekly intake for metals (Pb, Sn, and Zn) in all fish species were lower than the allowable limit defined by Joint FAO/WHO Committee; therefore, consumption of these fishes seems to be safe.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
