The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms

Environmental Toxicology, EarlyView.
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.

Spatial variations of small phytoplankton contributions in the Northern Bering Sea and the Southern Chukchi Sea

GIScience & Remote Sensing, 2019
Phytoplankton size classes (hereafter, PSCs) were derived from satellite ocean color data using a present phytoplankton abundance-based optical algorithm in the northern Bering and southern Chukchi Seas to characterize the spatial and seasonal variations

Cyanogenic Compounds, Physicochemical Parameters and Metals in Water From Cassava Processing Areas: A Study in the Brazilian Amazon, Using Multivariate Analysis

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the water quality of artesian wells and effluents generated in cassava processing in a rural area of Bragança, Pará, with emphasis on physicochemical parameters, multielement composition, and cyanogenic compounds. The well water presented specific nonconformities, highlighting pH values below the recommended level and high

Defining the ecological strategies of phytoplankton associated bacteria

Nature Communications
Ecological interactions between phytoplankton and bacteria govern the productivity and biogeochemistry of aquatic ecosystems. However, our understanding of these partnerships primarily comes from laboratory-based model systems, meaning that little is ...

Insight into diversity change, variability and co-occurrence patterns of phytoplankton assemblage in headwater streams: a study of the Xijiang River basin, South China

Frontiers in Microbiology
Phytoplankton has been used as a paradigm for studies of coexistence of species since the publication of the “paradox of the plankton.” Although there are a wealth of studies about phytoplankton assemblages of lakes, reservoirs and rivers, our knowledge ...

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.
