A study of western Lake Erie finds harmful algal blooms make a wider range of bioactive cyanopeptides beyond microcystin. Scientists sampled lake water across seasons, linked compounds to bacteria, and found mixtures can increase cellular toxicity.
A UN report warns that rising global demand for minerals for clean energy is causing environmental damage, water loss and health harms in poorer mining regions, while richer countries gain most benefits. The report urges reforms to protect water and people.
New research finds that PFAS chemicals in products and contaminated drinking water can reduce antibody production in adults, making the immune response to a new virus weaker. The study highlights risks for some groups and supports water regulation.
A study from Iowa State University shows some common cleaning methods for recyclable plastic can release phthalates into wash water. Ultrasonic cleaning and detergent with sodium hydroxide released DEHP and DCHP, and reuse of water raised DEHP levels.
Guanacaste is Costa Rica's driest province and attracts tourists and foreign buyers. Rapid coastal development has increased water shortages, pollution and local protests, while officials and studies warn aquifers and ageing water systems are under pressure.
