Ecofriendly remediation of cadmium, lead, and zinc using dead cells of Microcystis aeruginosa.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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 utilization of cyanobacteria toxin-producing blooms for metal ions adsorption has garnered significant attention over the last decade. This study investigates the efficacy of dead cells from Microcystis aeruginosa blooms, collected from agricultural drainage water reservoir, in removing of cadmium, lead, and zinc ions from aqueous solutions, and simultaneously addressing the mitigation of toxin-producing M. aeruginosa bloom. Some physical characterization of the dead biomass was performed, including scanning electron microscope (SEM) which revealed that, the cells form a dense, amorphous cluster, energy-dispersive X-ray (EDX) spectroscopy confirmed that carbon, oxygen, and nitrogen are the predominant elements in the biomass, Fourier transformation infrared (FTIR) spectroscopy identified several active function groups, including hydroxyl, aliphatic C-H amide I and amide II bands, carboxylate and carbonyl (C=O). Key factors influencing the adsorption process were examined. Under optimal conditions-pH 6, a biosorbent dose of 0.3 g, contact time of 90 min, primary metal level of 100 mg/L and temperature of 35 °C (313K)-a maximum removal efficiency exceeding 90% was achieved. Isothermal analysis revealed that the adsorption of Cd(II), Pb(II), and Zn(II) followed the Langmuir isotherm model (R
