Fractionation of heavy metals in bottom sediments in Chahnimeh 1, Zabol, Iran.
Article in Environmental monitoring and assessment, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
In the present study, 180 sediment samples were collected from the Chahnimeh 1 reservoir to investigate the concentration of metal and sequential extraction. Five geochemical phases (exchangeable fraction, carbonate fraction, Fe/Mn oxide fraction, organic fraction and residual fraction) for the determination of the speciation of heavy metals (Zn, Fe, Cd, Pb, Mn, Ni) as proposed by Tessier was applied to sediments collected from Chahnimeh 1. Results were obtained for nickel and cadmium, as over 40 % of metal was present in the exchangeable phase and bound to carbonate. According to the risk assessment code (RAC), sediments that have 31 to 50 % carbonate and exchangeable fraction are high risk. Similar results were obtained for zinc and lead. The major fraction of the two metals (63 % of the total concentration for lead and 85 % of the total concentration for zinc) occurred in the residual phase and fraction-bound hydrous Fe-Mn oxides. The risk assessment showed moderate risk for lead and no risk for zinc. This indicates that the Igeo and IPOLL used in the present investigation showed no pollution to moderate pollution in terms of metals in sediments.
