How PFAS chain length influences environmental fate and water treatment
How PFAS chain length influences environmental fate and water treatment
Per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals," are among the most persistent contaminants found in water systems worldwide. Their strong carbon-fluorine bonds make them highly resistant to degradation, allowing them to remain in the environm

More than 90% of key nutrients degrading the Mar Menor lagoon come from recirculated under
More than 90% of the key nutrients degrading the Mar Menor, such as ammonium, phosphorus and silica, do not come from streams or continental groundwater, but rather through a mechanism that has so far been overlooked: Water from the lagoon itself infiltrates the sediments and re-
