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.

COVID-19 Lockdown Measures Affect Air Pollution from Cities Differently

In Chaos, researchers in China created a network model drawn from the traffic index and air quality index of 21 cities across six regions in their country to quantify how traffic emissions from one city affect another. They leveraged data from COVID-19 lockdown procedures to better explain the relationship between traffic and air pollution and turned to a weighted climate network framework to model each city as a node using data from 2019 and 2020. They added a two-layer network that incorporated different regions, lockdown stages, and outbreak levels.

UN’s Sustainable Development Goals (SDGs) have impact on textile wastewater pollution research

The world’s research effort into wastewater pollution caused by the textiles industry has increased threefold over the past five years, according to a new analysis released this week in the lead up to Earth Day (Friday 22 April).

Researchers Link Pollution to Cardiovascular Disease, Develop Strategies to Reduce Exposure and Encourage Government Intervention

In a new review article, published today in The New England Journal of Medicine, researchers from University Hospitals (UH), Case Western Reserve University and Boston College discuss evidence linking pollution and cardiovascular disease. The research team highlights strategies for reducing individual exposure to pollution, and the importance of government-supported interventions encouraging clean energy.

University of Oregon economist finds polluters sometimes game system to avoid penalties

Eric Zou, an assistant professor in the UO economics department, found that companies and in some cases government agencies will do what they can to help their communities’ air pollution levels meet federal standards, which he documented in a paper published earlier this year: “Unwatched Pollution: The Effect of Intermittent Monitoring on Air Quality.”

AI-driven dynamic face mask adapts to exercise, pollution levels

Researchers reporting in ACS Nano have developed a dynamic respirator that modulates its pore size in response to changing conditions, such as exercise or air pollution levels, allowing the wearer to breathe easier when the highest levels of filtration are not required.

Researchers find eco-friendly way to dye blue jeans

Researchers from the University of Georgia developed a new indigo dyeing technology that’s kinder on the planet. The new technique reduces water usage and eliminates the toxic chemicals that make the dyeing process so environmentally damaging. And to top it off, the technology streamlines the process and secures more color than traditional methods.

False spring: Climate change may erode frogs’ ability to withstand salt pollution

Climate change may erode frogs’ ability to withstand road salt pollution, according to researchers at Binghamton University, State University of New York.

UCI is No. 2 in Sierra magazine’s 2021 ‘Cool Schools’ ranking of sustainability leaders

Irvine, Calif., Sept. 9, 2021 — The green streak continues! Sierra magazine has named the University of California, Irvine No. 2 overall in its annual “Cool Schools” ranking of sustainability leaders among U.S. and Canadian universities and colleges, marking the 12th time in a row that UCI has placed in the top 10 of the widely acclaimed list.

Computational Evaluation of Drug Delivery Reveals Room for Inhalers Improvement

Increased air pollution in recent years has exacerbated health risks for people who suffer from pulmonary diseases and these dynamics underscore the importance of increasing the efficacy of drug delivery devices that administer active pharmaceutical ingredients to treat respiratory illnesses. In Physics of Fluids, researchers describe developing a computational evaluation of drug delivery through both pressurized metered-dose inhalers and dry powder inhalers to determine how the process can be improved.

Common Environmental Pollutants Damage Mucus Structure, Function

In Biophysics Reviews, researchers review recent scientific literature about the effects of particle contaminants on the mucosal system, an internal membrane that serves as the body’s lubricant and the first line of defense from infections and toxins. These data establish a clear link between exposure to airborne or waterborne particulate matter and several health conditions.

What’s Killing Coral Reefs in Florida is Also Killing Them in Belize

Only 17 percent of live coral cover remains on fore-reefs in Belize. A study finds new evidence that nitrogen enrichment from land-based sources like agriculture run-off and sewage, are significantly driving macroalgal blooms to increase on the Belize Barrier Reef and causing massive decline in hard coral cover. With only 2 percent of hard coral cover remaining in the Florida Keys National Marine Sanctuary, it’s too late to save that reef, but there’s still hope for the Belize Barrier Reef.

2 in 1 Face Mask Against Dust and Virus – Chula Health Innovation in the New Normal

Chula’s Faculty of Engineering joins hands with PTT to develop a 2 in1 face mask, an innovation that protects against PM2.5 dust particles and COVID-19 virus that can be reused more than 15 times, helps reduce waste, is pollution-free, and will be available for sale soon.

Turning Plastic into Foam to Combat Pollution

In Physics of Fluids, researchers have developed a method to turn biodegradable plastic knives, spoons, and forks into a foam that can be used as insulation in walls or in flotation devices. The investigators placed the cutlery into a chamber filled with carbon dioxide. As pressure increased, the gas dissolved into the plastic. When they suddenly released the pressure in the chamber, the carbon dioxide expanded within the plastic, creating foaming.

Air pollution from wildfires impacts ability to observe birds

Researchers from the University of Washington provide a first look at the probability of observing common birds as air pollution worsens during wildfire seasons. They found that smoke affected the ability to detect more than a third of the bird species studied in Washington state over a four-year period. Sometimes smoke made it harder to observe birds, while other species were actually easier to detect when smoke was present.

Key to Carbon-Free Cars? Look to the Stars

In a decade-long quest, scientists at Berkeley Lab, the University of Hawaii, and Florida International University uncover new clues to the origins of the universe – and land new chemistry for cleaner combustion engines

Mitigating emissions in the livestock production sector

A new study shows that emission intensity per unit of animal protein produced has decreased globally over the past two decades due to greater production efficiency, raising questions around the extent to which methane emissions will change in the future and how we can better manage their negative impacts.

Surge in Nitrogen Has Turned Sargassum into the World’s Largest Harmful Algal Bloom

Scientists have discovered dramatic changes in the chemistry and composition of Sargassum, floating brown seaweed, transforming this vibrant living organism into a toxic “dead zone.” Results suggest that increased nitrogen availability from natural and anthropogenic sources, including sewage, is supporting blooms of Sargassum and turning a critical nursery habitat into harmful algal blooms with catastrophic impacts on coastal ecosystems, economies, and human health. Globally, harmful algal blooms are related to increased nutrient pollution.
