Water disinfection with ozone
While chlorine and ultraviolet light are the standard means of disinfecting water, ozone is equally effective in killing germs. To date, ozone has only been used as an oxidation agent for treating water in large plants. Now, however, a project consor.....»»
New algorithm rights wrongs of precipitation-type classification over Tibetan Plateau
Like many natural phenomena, precipitation can be both a blessing and a scourge to human life. On the one hand, it supplies our rivers and fields with water; on the other hand, it can cause floods, landslides, and other natural disasters. Either way,.....»»
Study finds mine-drainage treatment cost effective, but far more costs lay ahead
New research led by the University of Pittsburgh shows that state and federal appropriations allowing Pennsylvania to treat abandoned mine drainage works to both successfully and cost effectively clean up the acidic water—particularly to the benefi.....»»
What killed fish for miles in the South River? Atlanta officials are investigating
Officials are investigating a pollution incident that occurred earlier this month a few miles south of downtown Atlanta, which local water advocates say sent toxins into a tributary of the South River and killed fish for miles downstream......»»
Researchers use training model to map planted and natural forests via satellite image
While planting trees may seem like an easy win to combat climate change, planted forests often encroach on natural forests, wetlands, and grasslands. This can reduce biodiversity, disturb the natural environment, and disrupt carbon and water cycling......»»
Paying attention to errors can improve fused remote monitoring of lakes, researchers say
Lakes can tip the scales from healthy to potential environmental hazard quickly when they become eutrophic. In this state, an abundance of nutrients accelerates algae growth, which then crowd the water's surface and block light from reaching organism.....»»
South Sudan May See the First Permanent Mass Displacement Due to Climate Change
Protracted flooding has engulfed the country’s Sudd region due to more water entering the Nile upstream, which is driving conflict and disease and is potentially leaving the region uninhabitable......»»
Del Grande dealerships get ahead of California turf crackdown with low-water landscaping
When California announced a coming ban on watering ornamental turf, Del Grande Dealer Group made a plan to save water, save money and upgrade its Silicon Valley landscaping with native plants.....»»
Researchers identify novel approach to minimize nitrogen loss in crops
While agriculture producers apply nitrogen fertilizer to supply nutrients to their crops, they can't always keep those nutrients in the soil for maximum efficiency, often losing them into the atmosphere or water supply as nitrates and nitrous oxide......»»
New method to break down forever chemicals uses nanoparticles and ultrasound
What do firefighting foam, non-stick cookware, water-repellent textiles and pesticides all have in common? They all contain per- and polyfluoroalkyl substances, or PFAS—human-made chemicals that don't break down naturally. It's no wonder, then, tha.....»»
An evolutionary battleground: Plants vs. microbes
Gazing out on a freshwater pond, you may see tiny green plants with oval-shaped leaves floating in clusters. In overgrown ponds, these plants coat the water's surface. These plants—called duckweed or water lentils—can grow so fast that they can d.....»»
The legacy of corn nitrogen fertilizer: Study shows lengthy impact in tile drained systems
Midwestern soils are among the most productive in the world, thanks in part to extensive tile drainage systems that remove excess water from crop fields. But water isn't the only thing flowing through tile drains. Nitrogen moves along with soil water.....»»
Ozone pollution reduces yearly tropical forest growth by 5.1%, study finds
Ozone gas is reducing the growth of tropical forests—leaving an estimated 290 million tonnes of carbon uncaptured each year, new research shows......»»
High-Andean wetlands release more CO₂ under short-term warming, study suggests
The high-Andean wetlands of the Argentinean Puna region, called "vegas" by local inhabitants, although covering less than 1% of this arid mountain region, are important ecosystems as they support biodiversity and provide local people with fresh water.....»»
Proposed underwater data center surprises regulators who hadn’t heard about it
Startup NetworkOcean wants to sink GPUs into San Francisco Bay. (credit: BalticServers.com) Data centers powering the generative AI boom are gulping water and exhausting electricity at what some researchers view as an un.....»»
VW recalls nearly 100,000 ID4s over faulty door handles
Insufficient water protection in the 2021-24 Volkswagen ID4 handles could cause the door to fly open while the vehicle is moving because of circuit board malfunctions......»»
Chromium doping enhances catalyst performance for faster oxygen evolution
A group of researchers has made significant progress in developing cost-effective catalysts for the oxygen evolution reaction (OER), a critical component in technologies such as water splitting and metal-air batteries......»»
Hanoi river level hits 20-year high as SE Asia typhoon toll nears 200
Residents of Vietnam's capital waded through waist-deep water Wednesday as river levels hit a 20-year high and the toll from the area's strongest typhoon in decades rose to at least 179, with neighboring nations also enduring deadly flooding and land.....»»
Carbohydrate polymers could be a sweet solution for water purification
Water polluted with heavy metals can pose a threat when consumed by humans and aquatic life. Sugar-derived polymers from plants remove these metals but often require other substances to adjust their stability or solubility in water......»»
Study finds tire abrasion particles threaten fresh water habitats
A research team led by Prof. Dr. Markus Pfenninger from the Senckenberg Biodiversity and Climate Research Center Frankfurt (SBiK-F) has investigated the effects of tire-abrasion particles on freshwater ecosystems......»»
