Marine Seagrass Meadows Show Resilience to ‘Bounce Back’ After Die-Offs

A study in Florida Bay, one of the largest global contiguous seagrass systems, examined if a phytotoxin that accumulates as seagrass ecosystems become more enriched in nutrients prevents a marine seagrass, turtlegrass, from recruiting into open bare sediment following die-off events. While they do “bounce back,” long-term monitoring indicates the timeframe for recovery after major die-off events is at least a decade. Turtlegrass can successfully recruit into open bare sediment following die-off events due to biomass partitioning.

Treating Polluted Water with Nanofiber Membranes

In Biointerphases, researchers develop a fabrication method to increase the efficacy and longevity of membrane separation technology. The team created a nanofibrous membrane with electrospinning, in which a liquid polymer droplet is electrified and stretched to make fibers, and increased the roughness of the membrane surface by loading it with silver nanoparticles. In water, this rough surface promotes a stable layer of water, which acts as a barrier to prevent oil droplets from entering the membrane. The technology is greater than 99% effective at separating a petroleum ether-in-water emulsion.

GW Experts Available: EPA Proposes Historic Auto Pollution Limits That Would Boost EV Sales

The Environmental Protection Agency announced Wednesday plans that would ensure two-thirds of new passenger cars and a quarter of new heavy trucks sold in the United States are all-electric by 2032. According to The New York Times, “if the two rules…

Scientists discover a way Earth’s atmosphere cleans itself

Irvine, Calif., April 7, 2023 — Human activities emit many kinds of pollutants into the air, and without a molecule called hydroxide (OH), many of these pollutants would keep aggregating in the atmosphere. How OH itself forms in the atmosphere was viewed as a complete story, but in new research published in Proceedings of the National Academy of Sciences, a research team that includes Sergey Nizkorodov, a University of California, Irvine professor of chemistry, report that a strong electric field that exists at the surface between airborne water droplets and the surrounding air can create OH by a previously unknown mechanism.

FAU Developed AUTOHOLO Shows Potential as Red Tide Warning System

Current methods to monitor red tide are limited. Using AUTOHOLO, a new autonomous, submersible, 3D holographic microscope and imaging system, a study is the first to characterize red tide in the field and breaks new ground for monitoring harmful algal blooms.

Proximity to electric vehicle charging stations positively impacts home values

A new study finds that proximity to electric vehicle charging stations (EVCSs) can raise property values depending on where homes are situated. The study, conducted by a team of researchers from the University of Rhode Island, the University of Maryland College Park, Princeton University and Cardiff University, was recently published in Nature Sustainability.

Marine Plankton Tell the Long Story of Ocean Health, and Maybe Human Too

UC San Diego researchers suggest that rising levels of manmade chemicals, accumulating in marine plankton, might be used to monitor the impact of human activity on ecosystem health and perhaps study links between ocean pollution and land-based rates of childhood and adult chronic illnesses.

Toxins from Harmful Algae Found in Bull Sharks of Florida’s Indian River Lagoon

The Indian River Lagoon (IRL) is a bull shark nursery habitat crucial to survival and recruitment of Atlantic coast bull sharks. Analysis of 123 samples found the presence of one or more phycotoxin from harmful algal blooms in 82 percent of the bull sharks and their prey items. Findings highlight the potential threat of toxic algae to the IRL’s ecosystem and surrounding human populations that may consume the same prey species. The highest concentrations of most toxins were detected in gut content samples, highlighting dietary exposure as an important mechanism of toxin transfer to bull sharks in the system.

Review: Are Climate Change and Air Pollution Making Neurologic Diseases Worse?

People with neurologic diseases like headache, dementia, multiple sclerosis (MS) and Parkinson’s disease may experience worsening symptoms due to climate change, according to a scoping review of research published in the November 16, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Blind spots in the monitoring of plastic waste

Whether in drinking water, food or even in the air: plastic is a global problem – and the full extent of this pollution may go beyond of what we know yet. Researchers at the Karlsruhe Institute of Technology (KIT), together with partners from the Netherlands and Australia, have reviewed conventional assumptions for the transport of plastic in rivers.

Low-Cost Air Quality Sensors Deliver Insights on Environmental Injustice

Networks of low-cost air quality sensors are able to detect temporary peaks and “hot spots” in air pollution and could be a better tool for tracking short-term changes in air quality in communities than regulatory sensors. Monitoring fine-scale, real-time changes in air pollution could support efforts to protect public health.

Does Traffic-Related Air Pollution Increase Risk of Dementia?

Higher exposure to a certain type of traffic-related air pollution called particulate matter may be linked to an increased risk of dementia, according to a meta-analysis published in the October 26, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology. Researchers specifically looked at fine particulate matter, PM2.5, which consists of pollutant particles of less than 2.5 microns in diameter suspended in air. The meta-analysis included all available studies on air pollution and risk of dementia.

Today: ANA2022 Media Roundtable to Spotlight Latest in Neuro Research

As Winters Warm, Nutrient Pollution Threatens 40% of U.S.

Scientists are ringing alarm bells about a significant new threat to U.S. water quality: as winters warm due to climate change, they are unleashing large amounts of nutrient pollution into lakes, rivers, and streams.

The first-of-its-kind national study finds that previously frozen winter nutrient pollution—unlocked by rising winter temperatures and rainfall—is putting water quality at risk in 40% of the contiguous U.S., including over 40 states.

Chula Launches a Bioproduct “Microbes to Clean Up Oil Spill in the Ocean”

WashU Expert: Jackson water issues result of environmental racism

The increasing demand for electric vehicles and cell phones has accelerated the need for safer energy storage after numerous instances of commercial lithium-ion batteries overheating and catching fire.

Water Quality Woes in Southwest Florida Linked to Seeping Septic Systems

From fecal bacteria to blue-green algae to red tides, Southwest Florida’s water quality has declined as its population has increased. Multiple lines of evidence from a multi-year microbial source tracking study points to septic systems as a contributing source for this decline. The study is one of few to connect downstream harmful algal blooms with nutrient loading from upstream septic systems. These water quality issues are caused by aging septic systems installed in high densities in areas with shallow water tables. Septic systems may actually be sitting in groundwater during certain times of the year, which means that they cannot function properly.

Unchecked emissions could double heat-related child mortality

If carbon emissions are limited to slow temperature rise, up to an estimated 6,000 child deaths could be prevented in Africa each year, according to new research. A team of international scientists, led by the University of Leeds in collaboration with researchers at the London School of Hygiene & Tropical Medicine (LSHTM), have shown that thousands of heat-related child deaths could be prevented if temperature increases are limited to the Paris Agreement’s 1.5ºC target through to 2050.

Specific Environmental Exposures may Help Predict Increased Risk of Death from Cardiovascular Disease

A new study from the Icahn School of Medicine at Mount Sinai quantifies the cardiovascular risk posed by exposure to specific environmental factors, showing, for example, that air pollution heightens the risk of heart disease mortality by 17 percent.

Including all types of emissions shortens timeline to reach Paris Agreement temperature targets

Instead of focusing on carbon dioxide’s effect on future temperature, new research includes the related human-generated emissions of methane, nitrogen oxide and particle pollution. Expanding the scope increases the amount of future warming that is already guaranteed by past emissions, and shortens the timeline to reach the Paris Agreement temperature targets.
