Organ-specific bioaccumulation and deterministic health risk assessment of selected heavy metal(loid)s in commercial fish from a southern harbor region (Nagapattinam).

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
Introduction: Heavy metal contamination of coastal waters results in bioaccumulation in fish, posing a significant route of human exposure via seafood consumption. The present study focuses on organ-specific metal distribution and associated health risk indices in three important fish species from the Nagapattinam coast, India. Methods: In the current study, three species of fish ( Results: The concentrations were found to be in the range of 0.025-21.53 μg kg Discussion: Overall, the findings suggest low non-carcinogenic risk under average consumption conditions; however, the estimated carcinogenic risk for chromium exceeded the commonly referenced acceptable threshold under conservative assumptions and should therefore be interpreted with caution. These results highlight the need for further investigation, particularly chromium speciation analysis, to refine risk estimates for fish consumed from the Nagapattinam marketplace.
