How high are concentrations of microplastics in the environment, in our drinking water or in foods? Researchers at the Technical University of Munich (TUM) have developed an automated analysis method for the identification and…

Since de-icing with road salt began in the 1930s, the salinity of lakes across much of the US has been steadily increasing, posing a potential threat to aquatic life and drinking water supplies. However, a cautiously optimistic new study in…

A new study by researchers at Columbia University Mailman School of Public Health shows that water arsenic levels are linked to higher urinary arsenic among the U.S. population for users of both private wells and public water systems. The…

It is a cruel paradox that on a planet with a surface mostly covered by water, hundreds of millions of people don't have access to clean drinking water. As for the pollution of potable and natural water sources, one of the main culprits is…

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a fast and cost-effective method to test liquids for a ubiquitous family of chemical compounds known as amphiphiles, which are…

Since the outbreak of COVID-19, the importance wearing masks and disinfection of items has become paramount. As a result, there is now a greater need for effective, potent, and simple-to-apply disinfectants. Foam-type disinfectants are a…

The extent of plastic pollution remains largely hidden from view in the form of microplastics (MPs): plastic particles with diameters less than 5 mm. Since plastics are slow to degrade, they fragment into tiny particles that end up…

Researchers have harnessed the light-guiding properties of spider silk to develop a sensor that can detect and measure small changes in the refractive index of a biological solution, including glucose and other types of sugar solutions. The…

Lead concentrations allowed in children's fruit juice to be slashed to 20% of current levels, FDA says, but consumer watchdogs slam plan as 'weak' and not protecting healthFood and Drug Administration says permitted lead…

A study on metal concentrations in U.S. community water systems (CWS) and patterns of inequalities, researchers at Columbia University Mailman School of Public Health found that metal concentrations were particularly elevated in CWSs…
