These Teabags Aren’t for Making Tea — They Remove Arsenic | Newswise
[ad_1] Newswise — Arsenic contamination in drinking water is a global issue, with over 200 million people estimated to be at risk. While water treatment plants remove the metal, the problem persists in low-resource areas or undertreated well water. So, researchers reporting in ACS Omega have designed a simple solution: an arsenic-removing teabag. The system is inexpensive, costing around 7 cents to clean a liter of water, and highly effective, removing over 90% of the arsenic ions present. “Clean drinking water should not depend on access to expensive […]
Recycling Plants’ Plastic-Cleaning Process May Pose Water Contamination Risks | Newswise
[ad_1] Newswise — AMES, Iowa – Potentially harmful chemicals can contaminate untreated water used in recycling plants to clean plastics before they’re processed into new products, according to a new study by an Iowa State University research group. Researchers from Iowa State’s Polymer and Food Protection Consortium tested common industrial plastic-washing practices and found that […]
Elevated Lead Levels Could Flow From Some US Drinking Water Kiosks | Newswise
[ad_1] Newswise — After high-profile water crises like the one in Flint, Michigan, some Americans distrust the safety of tap water, choosing to purchase drinking water from freestanding water vending machines or kiosks. Yet this more expensive water may contain different pollutants than local tap water, according to a study in ACS’ Environmental Science & […]
KRICT Develops Microfluidic Chip for One-Step Detection of PFAS and Other Pollutants | Newswise
[ad_1] Newswise — Environmental pollutant analysis typically requires complex sample pretreatment steps such as filtration, separation, and preconcentration. When solid materials such as sand, soil, or food residues are present in water samples, analytical accuracy often decreases, and filtration can unintentionally remove trace-level target pollutants along with the solids. To address this challenge, a joint […]
