Novel method for combining microbial bioremediation with static magnetic fields to remediate mercury-contaminated soils.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Heavy metal contamination poses a significant risk to both the environment and public health, particularly through metallic mercury, a neurotoxic contaminant capable of bioaccumulating in food chains. This article presents a novel approach to remediating mercury-polluted soils by combining microbial bioremediation with the effects of a static magnetic field, applied at an induction of 260 mT for 12 hours at the start of the experiment. The decontamination technique was applied to mercury-contaminated soil bioaugmented with the bacterial strain Pseudomonas stutzeri LBR. Mercury remediation was enhanced by the static magnetic field in conjunction with bioaugmentation over a 30-day period. Notably, in non-sterile soils, the combination of an SMF, total soil flora, and Pseudomonas stutzeri LBR increased mercury remediation efficiency by 49.36%, compared to only 23.85% in the absence of an static magnetic field and soil bioaugmentation. Similarly, in sterile soils, the combination of an static magnetic field and Pseudomonas stutzeri LBR increased mercury remediation efficiency by 72.49%, compared to 38.1% without an static magnetic field and soil bioaugmentation. This study highlights the potential of combining an static magnetic field with microbial bioremediation to accelerate the remediation of mercury-contaminated soils, suggesting that this approach may become increasingly important in the future.
