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

open access: yesEnvironmental 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.

Faecal bacteria and coliphages in run-off from dairy farms [PDF]

open access: yes, 2005
Although the indicator numbers were mainly quite low, there was a severe risk of transfer of pathogens to the environment, especially when household wastewater or surface run-off water from outdoor yards was poorly purified and allowed to flow into ...

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

Application of microorganisms to determine the impact of infiltration layer and season on pit latrine groundwater contamination

open access: yesSustinere: Journal of Environment and Sustainability
This study was necessitated as a result of the frequent cases of diarrhoea observed among the students of the researcher. The researcher employed faecal indicator bacteria to assess the impact of the infiltration layer and seasonal variations on ...

Evaluation of Peel Plate™ EC for Determination of E. coli and Coliform or Total Coliform in Dairy Products

open access: yesJournal of AOAC INTERNATIONAL, 2016
Abstract Peel Plate™ EC is a low-profile plastic, 47 mm culture dish with an adhesive top that contains a dried medium with Gram-negative selective agents and with enzyme substrate indicators for β-galactosidase (coliform) and β-glucuronidase (Escherichia coli). The method provides a conventional quantitative coliform (red) and E.

Effects of Live and Heat‐Treated Bifidobacterium longum CECT 7347 in Adults With Allergic Rhinitis: A Randomised, Double‐Blind, Placebo‐Controlled Trial

open access: yesAllergy, EarlyView.
This randomized, double‐blind, placebo‐controlled trial evaluated the effects of live probiotic and HT postbiotic B. longum CECT 7347 in adults with moderate–severe allergic rhinitis. Postbiotic supplementation for 8 weeks significantly reduced CSMS and dSS, exceeding the established CSMS MCID with a 33% greater improvement, when compared to placebo ...

Interplay of crop diversity and agricultural area in agroecosystem services: Analytical and empirical study on local water quality

open access: yesCanadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract This study expands the framework for analyzing the interplay of agricultural area and crop diversity on agroecosystem services by incorporating the species‐area relationship concept from biology. We estimate panel fixed effects models that include both agricultural area and crop diversity, along with their interaction term.
