Light-dominated selection shaping filamentous cyanobacterial assemblages drives odor problem in a drinking water reservoir

open access: yesnpj Clean Water, 2022
Filamentous cyanobacteria have substantial niche overlap, and the causal mechanism behind their succession remains unclear. This has practical significance since several filamentous genera are the main producers of the musty odorant 2-methylisoborneol ...

Enhancement of micropollutant biotransformation by adding manganese sand in constructed wetlands

open access: yesHeliyon, 2023
Recent investigations have shown that the addition of manganese (Mn) sand to constructed wetlands (i.e., Mn-amended CWs) can improve the performance of organic micropollutants (MPs) removal. In addition to the direct oxidation and adsorption of Mn oxides,

Controlling Legionella pneumophila in Showerheads: Combination of Remedial Intervention and Preventative Flushing

open access: yesMicroorganisms, 2023
Shock chlorination and remedial flushing are suggested to address Legionella pneumophila (Lp) contamination in buildings or during their (re)commissioning. However, data on general microbial measurements (adenosine tri-phosphate [ATP], total cell counts [

Understanding soil selenium accumulation and bioavailability through size resolved and elemental characterization of soil extracts

open access: yesNature Communications, 2022
Selenium is essential for human health and mainly delivered via terrestrial foodstuffs. An advanced characterization of selenium chemical forms shows that organic matter increases its accumulation in soils but could limit its supply to ...

Determination of Phenols Isomers in Water by Novel Nanosilica/Polydimethylsiloxane-Coated Stirring Bar Combined with High Performance Liquid Chromatography-Fourier Transform Infrared Spectroscopy

open access: yesScientific Reports, 2017
A novel nanosilica/polydimethylsiloxane (SiO2/PDMS) coated stirring bar was adopted in the sorption extraction (SBSE) of phenols in water, and the high performance liquid chromatography-fourier transform infrared spectroscopy (HPLC-FTIR) was subsequently

A Model Study on the Role of Wetland Zones in Lake Eutrophication and Restoration

open access: yesThe Scientific World Journal, 2001
Shallow lakes respond in different ways to changes in nutrient loading (nitrogen, phosphorus). These lakes may be in two different states: turbid, dominated by phytoplankton, and clear, dominated by submerged macrophytes. Both states are self-stabilizing;

Evaluation of environmental factors and microbial community structure in an important drinking-water reservoir across seasons

open access: yesFrontiers in Microbiology, 2023
The composition of microbial communities varies in water and sediments, and changes in environmental factors have major effects on microbiomes. Here, we characterized variations in microbial communities and physicochemical factors at two sites in a large
