Forever chemical pollution can now be tracked      (via sciencedaily.com)     Original source 

Researchers developed a way to fingerprint organofluorine compounds -- sometimes called 'forever chemicals' --which could help authorities trace them to their source when they end up in aquifers, waterways or soil.

Water delivered to the mantle by aluminum enriched hydrated slabs?      (via sciencedaily.com)     Original source 

Researchers found a notable effect of aluminum on the sound velocities of superhydrous phase B, a dense hydrous magnesium silicate and potential host of water in the deep Earth. Their results suggest that aluminous phase B could explain seismic velocity anomalies in the Earth's mantle transition region and uppermost lower mantle.

South Florida estuaries warming faster than Gulf of Mexico, global ocean, USF research shows      (via sciencedaily.com)     Original source 

Estuaries in South Florida have experienced rapid warming over the past two decades, including a record-breaking marine heat wave in 2023, research shows. The findings paint a troubling picture for the marine life that calls Florida home. Possible causes include evaporation, water capacity and residence time (the amount of time water spends in an estuary). No single factor has been identified as dominant.

New device for on-the-spot water testing      (via sciencedaily.com)     Original source 

Researchers at University of Galway have developed a new, portable technology for on-the-spot testing of water quality to detect one of the most dangerous types of bacteria. Ireland regularly reports the highest crude incidence rates of the pathogen Shiga toxigenic Escherichia coli -- STEC for short -- in Europe over the recent years.

Plants offer fruit to insects to disperse dust-like seeds      (via sciencedaily.com)     Original source 

Fruit exist to invite animals to disperse the swallowed seeds. A research team found that plants targeting insects rather than birds or mammals for this service are more common than previously thought. These plants produce dust-like seeds and fruit suitable for the minute, ground-dwelling animals.

New York City's fireworks display prompts temporary surge of air pollution      (via sciencedaily.com)     Original source 

In 2023, roughly 60,000 firework shells exploded above Manhattan's East River as part of Macy's Fourth of July show. The resulting air pollutant levels were many times higher in the hours after the display than those seen when smoke from a Canadian wildfire had blanketed the area a month before, according to the results of a new study.

Groundwater reserves in southwestern Europe more stable overall than previously thought      (via sciencedaily.com)     Original source 

Groundwater is a vital resource, sustaining plants and ecosystems, ensuring agricultural production and serving as a core component of drinking water supplies. However, climate change and anthropogenic pressures can threaten groundwater availability, especially in southwestern Europe. This threat was evaluated by a research team using multidecadal data from more than 12,000 groundwater wells in Portugal, Spain, France, and Italy. The surprising finding: Groundwater levels are not declining everywhere as widely believed, but primarily in semi-arid regions with intensive agriculture and frequent droughts. Declines are also observed in temperate regions associated with large urban areas. The authors conclude that, with suitable management practices, groundwater can be utilized sustainably.

Combined effects of plastic pollution and seawater flooding amplify threats to coastal plant species      (via sciencedaily.com)     Original source 

A new study highlights how a combination of environmental stressors -- namely plastic pollution and seawater flooding -- can increase the threats faced by plants in some of the planet's critical ecosystems. It showed that both stressors had some effects on the species tested, but being exposed to both microplastics and flooding together -- a threat likely to increase as a result of climate change and plastic use -- had a more pronounced impact on their resource allocation.

Research catalogs greenhouse gas emissions tied to energy use for interbasin water transfers      (via sciencedaily.com)     Original source 

Much of the water in the West is transported across vast geographical areas by large infrastructure projects known as interbasin water transfers. Two of these projects in particular make up 85% of all energy-related greenhouse gas emissions associated with U.S. interbasin transfers -- one in Arizona and the other in California -- according to the new research.

Green hydrogen: 'Artificial leaf' becomes better under pressure      (via sciencedaily.com)     Original source 

Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team has now shown that the efficiency of PEC cells can be significantly increased under pressure.
