UNH research: Journey of PFAS in wastewater facilities highlights regulation challenges

DURHAM, N.H.–Researchers at the University of New Hampshire have conducted two of the first studies in New England to collectively show that toxic man-made chemicals called PFAS (per-and polyfluoroalkyl substances), found in everything from rugs to product packaging, end up…

As water sources become scarce, understanding emerging subsurface contaminants is key

USC researchers modeled complex subsurface water flow to help assess the risk of contaminants appearing in high, unsafe concentrations in variable water sources.

Applying UV light to common disinfectants makes them safer to use

Over 400 common disinfectants currently in use could be made safer for people and the environment and could better fight the COVID-19 virus with the simple application of UVC light, a new study from the University of Waterloo shows. Benzalkonium…

CNIO researchers explain the toxicity of USP7 inhibitors, under development for cancer treatment

Understanding the components that control cell division is fundamental to understanding how life works and how alterations in this delicate process can cause diseases such as cancer. It was precisely the discoveries of “key regulators of the cell cycle” and…

IIVS to collaborate with RIFM to develop non-animal technologies for respiratory allergy

The Institute for In Vitro Sciences (IIVS) and the Research Institute for Fragrance Materials (RIFM) announce a collaboration to develop a non-animal ( in vitro ) test designed to assess potential respiratory allergens. Environmental, consumer, or workplace exposure to respiratory…

Rodenticides in the environment pose threats to birds of prey

Over the past decades, the increased use of chemicals in many areas led to environmental pollution – of water, soil and also wildlife. In addition to plant protection substances and human and veterinary medical drugs, rodenticides have had toxic effects…

Toxic PAH air pollutants from fossil fuels ‘multiply’ in sunlight

When power stations burn coal, a class of compounds called Polycyclic Aromatic Hydrocarbons, or PAHs, form part of the resulting air pollution. Researchers have found that PAHs toxins degrade in sunlight into ‘children’ compounds and by-products. Some ‘children’ compounds can…

Bioaccumulation of phased-out fire retardants is slowly declining in bald eagles

Research published in Environmental Toxicology and Chemistry shows that the presence of polybrominated diphenyl ethers (PBDEs) in bald eagle populations is slowly declining. Bald eagles are apex predators that nest and, more importantly, feed along water bodies, making them excellent…
