Contamination by Potentially Toxic Elements (PTEs) in Agricultural Products Grown Around Sepetiba Bay, Rio de Janeiro State (SE Brazil).
Article in Archives of environmental contamination and toxicology, 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 contamination of soil, water, and air by potentially toxic elements (PTEs) allows the transfer of metals to food. When introduced into food through soil, PTEs are absorbed by plant roots and transported to the bloodstream. The region surrounding Sepetiba Bay (SB), a densely populated area intensively exploited for tourist purposes, is one of the most contaminated by PTEs in the southeastern region of Brazil. Therefore, this study aims to evaluate (by ICP-MS) the concentrations of PTEs in agricultural products (roots, fruits, leaves, seeds, cheese, and eggs) cultivated and sold by rural producers in the region surrounding SB. The 26 food types selected for this study were produced in this region and purchased at local markets. The results for the analyzed foods revealed relatively high concentrations of Zn > Cu > Ni > Cr > As > Pb > Co > Hg > Cd, exceeding the limits established by ANVISA and international laws. Cluster analysis (CA) and principal component analysis (PCA) grouped the PTEs according to their possible sources: ore transport (Zn, Cu, Pb, and Cd), natural (Hg, Cr, and Ni), and fertilizers (Co and As). The CA allowed us to distinguish two main food groups in terms of the enrichment of PTEs. Group 1 contains leaves, animal products, and seeds with higher levels of Hg, Cr, Ni, Co, and As. Group 2 includes roots and fruits, which have higher concentrations of Zn, Cu, Pb, and Cd than Group 1. The Hazard Quotient (HQ) suggests that As and Cr pose a higher risk in foods of CA-Group 1 (leaves, animal products, and seeds). Hazard Index (HI) values > 1 indicate a risk of probable long-term carcinogenesis in adults. Thus, this study reveals that the continued consumption of food produced in the region surrounding SB could cause health problems for the local population.
