Hydrogen peroxide (H2O2) is a very popular disinfectant in the food industry and in clinical environments. In previous research on combined application of aPDT and H2O2, a satisfactory performance was not found and results pointed to antagonistic effects by including H2O2 immediately before illumination. ...
Pharmaceuticals and their metabolites are detected on an increasing scale in the aquatic environment. The pharmaceuticals (such as drugs) mostly get into the surface and drinking water through the excretions of humans and animals; however, the wastewater of pharmaceutical production facilities can also be contaminated with active ingredients. ...
Environmental Filters The health of estuaries is vital to both terrestrial and aquatic environments. They often act as environmental filters since they are located between fresh and salt water. ...
Whereas the hygienic condition of drinking and bathing water by law must be monitored by culture-based methods, for quantification of microbes and antibiotic resistance in soil or the aquatic environment, often molecular genetic assays are used. For comparison of both methods, knowledge of their correlation is necessary. ...
Beneficial microorganisms that are naturally present in the aquatic environment are typically at low levels, so they work much slower at reducing nutrients to maintain water quality. ...
TPP is now detected in various environments including aquatic ecosystems worldwide. However, studies on the toxicological consequences of chronic TPP exposure on aquatic organisms are scarce. ...
Phthalic acid esters are frequently detected in aquatic environment. In this study, zebrafish were exposed to low concentrations (0, 0.46, 4.0, and 37.5 µg/L) of mono‐(2‐ethylhexyl) phthalate (MEHP) for 81 days, and the effects on reproduction, gamete quality, plasma vitellogenin (VTG), sex steroids, and transcriptional profiles of key genes involved in ...
Tolerance of antibiotic susceptible and antibiotic resistant Escherichia coli, Enterococcus and Staphylococcus strains from clinical and wastewater samples against ozone was tested to investigate if ozone, a strong oxidant applied for advanced wastewater treatment, will affect the release of antibiotic resistant bacteria into the aquatic environment. For this ...
Interactions between insulin signaling and steroidogenesis suggest potential endocrine‐disrupting effects of metformin found in the aquatic environment. Adult fathead minnows (Pimephales promelas) were chronically exposed to metformin for 4 wk, at 40 µg/L, a level similar to the average found in WWTP effluent in Milwaukee, Wisconsin, USA. ...
The present study reports on the occurrence and chiral behavior of the anti‐inflammatory drug (S)‐naproxen (NAP), (S)‐2‐(6‐methoxynaphthalen‐2‐yl)propionic acid, in an aquatic environment under field and laboratory conditions. (S)‐NAP was detected in influents and effluents of sewage treatment plants (STPs) located in the Tama River basin Tokyo at ...
Therefore, long‐term exposure to low concentrations of PBDEs in zebrafish could cause reproductive impairment, suggesting that PBDEs may have significant adverse effects on fish population in the highly PBDEs‐contaminated aquatic environment. Environ Toxicol Chem © 2014 SETAC ...
Pentachlorophenol (PCP) is frequently detected in the aquatic environment and has been implicated as an endocrine disruptor in fish. ...
These findings suggest that interactions among multiple stressors can be complex and require examination in conjunction with one another to evaluate actual impacts to aquatic fauna. Environ Toxicol Chem © 2013 SETAC ...
Although BPA degrades rapidly in the environment with aquatic half‐lives from 0.5 to 6 d, it can be found in aquatic systems from widespread use. ...
Although intersex of fish species has been widely reported in aquatic environments, there is no appropriate biomarker of the effects to assess the occurrence of intersex. ...
Active pharmaceutical ingredient (API) residues have been found to be widespread in the aquatic environment, albeit in most cases at trace levels, with the route to the environment predominantly being via therapeutic use and subsequent excretion to sewer. Although manufacturing discharges may be a low overall contributor to environmental ...
Organic contaminants are continually entering aquatic environments and thence the tissues of resident biota. Mussels and other molluscs are used worldwide as sentinels in pollution monitoring. ...
From the results of this study, we concluded that the non-cholera-toxin-producing strains of V. cholerae, whether of clinical or environmental origin, possess the ability to produce a new secretogenic toxin that is entirely different from the toxin produced by toxigenic V. cholerae O1 and O139 strains. We also concluded that the aquatic environment is a reservoir ...
