A review of toxicity and remediation: thorium uptake by woody plants.
Review in Biodegradation, 2026. 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
Thorium is an extremely radioactive and hazardous material and there is increasing concern over the environmental impact of thorium on the health of soils. There have been a limited number of investigations into phytotoxicity, phytoremediation, and the mechanisms of thorium absorption by woody plants. The purpose of this review is to assess the impact of thorium on soil's physical, chemical, and biological characteristics and quantify how much thorium is available for woody plant uptake and how much thorium will be moved around within different parts of the plant. This review also examines the bioavailability, mobility and root uptake of thorium by woody plants. The extent to which woody plants absorb thorium has been reviewed according to three activity concentration rates: low, moderate and high. Furthermore, literature was reviewed and analyzed as to how woody plant absorption may be influenced by having elevated quantities of thorium in the soil, which exceeds the toxic threshold. Thorium adversely affects all living things through hindering seed germination, reducing plant growth, inhibiting photosynthetic rate, and reducing the plants' ability to absorb nutrients; thorium has not been demonstrated to have any biological function. Woody Plants can employ several methods to combat the negative effects of thorium, such as producing phytochelatins, utilizing multiple compartments for storing thorium, and producing many different types of enzymes that function as antioxidants. Therefore, there are numerous technologically based and microbially based methods available for remediating thorium-contaminated soils, one of which is the use of specific plant species as remedial agents. Finally, a thorough review of literature was performed to identify all native woody plants that are best adapted for phytoremediation of thorium-contaminated soils and the mechanisms used by these native woody plant species to protect themselves from the toxic effects of thorium contamination were determined.
