Influence of hydrological flows from tropical watersheds on the dynamics of Cu and Zn in sediments.

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
This work aimed to evaluate, on a spatial and temporal scale, the effect of the flow on the concentrations of Cu and Zn in sediments from two water bodies (the Alvorada and Mandaguari Rivers). Five sediment-sampling periods were conducted, under four different streams in each sampling point (shallow/fast (SF), shallow/slow (SS), deep/fast (DF), deep/slow (DS)). Each sampling point represented the spring, the middle, and the mouth of the evaluated rivers. Some climatic variables were also evaluated, such as monthly temperature and rainfall. In addition, temperature, pH, dissolved oxygen (DO), and total solids were evaluated. Cu and Zn concentrations were obtained by FAAS. Cu and Zn levels are affected by the speed and depth of the water column. The quality of the sediments is affected by human activities in the surroundings, and according to legislation, levels of Cu and Zn in sediments offer risks of medium and high effects to aquatic biota. The highest accumulation of Cu in sediments occurs during October (221 mg kg
