Assessing Trace Elements Bioaccumulation in Coastal River Fish and Shellfish: Implications for Human Health and Risk Evaluation.
Article in Biological trace element research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The presence of heavy metal contaminants in fish and shellfish in aquatic environments poses a risk to human health due to trophic transfer. This study determined the levels of various trace elements (Fe, As, Cr, Zn, Cu, Ni, Pb, and Cd) in the muscles, gills, and liver of hilsa (Tenualosa ilisha) and prawn (Macrobrachium rosenbergii) samples obtained from the Tetulia River, Bangladesh. The results showed that the level of trace elements in different body parts differed significantly (P < 0.05) between species, displayed below recommended threshold levels. The cumulative low to higher hierarchic concentration of the trace elements was as follows: Fe > Zn > Cu > Cr > Ni > Pb > As > Cd. Hilsa had significantly (P < 0.05) higher bioaccumulated trace elements compared to prawn. With the exception of Ni and Cd, the estimated daily intakes (EDI) for both adults and children were below the recommended daily allowance (RDA), which exhibits that other trace elements do not cause harm to human health. Furthermore, the hazard index (HI) and total hazard quotient (THQ) were also found to be within acceptable limits, taking into account the higher vulnerability of children to toxicity compared to adults. Notably, the HI suggested that children were approximately four times more susceptible to both carcinogenic and non-carcinogenic effects compared to adults. Ultimately, the levels of carcinogenic risk were deemed acceptable, despite the estimated values suggesting susceptibility to adverse effects in both adults and children. This study concluded that fish and shellfish may not pose a health risk to consumers, highlighting the importance of further monitoring of trace elements in the catchment area.
