In recent decades, change has defined our environment in the United States. But, says a new University of Wisconsin-Madison study, while those changes usually result in poor water quality, lakes have surprisingly stayed the same.
A new study published today (August 23) in the Journal of Air and Waste Management Association builds upon recent heavy-duty natural gas vehicle methane emission measurements to model methane emissions from a future, much larger vehicle fleet. This study, conducted by researchers at West Virginia University’s Center for Alternative Fuels, Engines, and Emissions, comes as the price of natural gas has decreased, leading to interest in natural gas as a cleaner replacement for diesel in heavy-duty vehicles.
In the megacities that are home to nearly 10 percent of the world’s 7.5 billion people, trees provide each city with more than $500 million each year in services that make urban environments cleaner, more affordable and more pleasant places to live.
Chemical engineers at the University of Notre Dame have discovered a catalytic process that could help curb emissions of nitrogen oxides (NOx) from diesel-powered vehicles, a priority air pollutant that is a key ingredient in smog.
For many, the commute to and from work is a lengthy, stressful process. According to the U.S. Census Bureau, it takes the average American about 26½ minutes to get to work. That’s nearly an hour each day — to work and back — to face traffic snarls and congested highways. That commute can also be hazardous to your health, exposing drivers to an increased amount of air pollutants that have been linked to a whole host of medical maladies, including cardiovascular disease, respiratory issues and even lung cancer.
Urban forests capture pollutants, store carbons and have other significant benefits that can be quantified
Manure is a reality in raising farm animals. Manure can be a useful fertilizer, returning valued nitrogen, phosphorus, and potassium to the soil for plant growth. But manure has problems. Odor offensiveness, gas emissions, nutrient runoff, and possible water pollution are just a few. New methods may reduce these negatives while potentially adding some positives: biochar covers.
Environmental scientists led by the Virginia Tech College of Science have discovered that the burning of coal produces incredibly small airborne particles of a highly unusual form of titanium oxide with the potential to be toxic to humans.

It was austral summer and the temperature outside hovered around -4 degrees Celsius.

Researchers will gather at the Perelman School of Medicine at the University of Pennsylvania this Monday to discuss these “Windows of Susceptibility."
Wildfires are major polluters. Their plumes are three times as dense with aerosol-forming fine particles as previously believed. For the first time, researchers have flown an orchestra of modern instruments through brutishly turbulent wildfire plumes to measure emissions in real time. They have also exposed other never before measured toxins.

The American Thoracic Society is extremely disappointed that President Trump has announced his decision to withdraw from the Paris agreement to address climate change. This agreement was signed by nearly every nation on Earth in recognition of our shared responsibility to solve this global environmental and public health crisis.
By swapping solar photovoltaics for coal, the US could prevent 51,999 premature deaths a year, potentially making as much as $2.5 million for each life saved. A team from Michigan Technological University calculated US deaths per kilowatt hour per year for coal related to air pollution-related diseases associated with burning coal.

New research from the University of Cincinnati (UC) reveals that residents of the Mid-Ohio River Valley had higher than normal levels of perfluorooctanoic acid (PFOA) based on blood samples collected over a 22-year span. The exposure source was likely from drinking water contaminated by industrial discharges upriver. This is the first study of PFOA serum concentrations in U.S. residents in the 1990s.
In an ATS 2017 International Conference first, respiratory health professionals and patients joined other conference attendees at a rally near the Capitol on Tuesday, May 23 to voice their concerns about recent policies that threaten to undermine many of the ATS’s advocacy priorities including: research funding, tobacco regulation, affordable health care, and clean air. Also participating in the rally was U.S. senators Edward Markey (D-MA) and Tom Carper (D-DE).WASHINGTON, DC – May 24, 2017 – In an ATS 2017 International Conference first, respiratory health professionals and patients joined other conference attendees at a rally near the Capitol on Tuesday, May 23 to voice their concerns about recent policies that threaten to undermine many of the ATS’s advocacy priorities including: research funding, tobacco regulation, affordable health care, and clean air.

Researchers Develop Novel Structure for a High-Efficiency Catalytic Converter Aimed at Boosting Automobile Manufacturers’ Ability to Meet Stringent Vehicle Emissions Standards
First, diesel vehicles tainted their reputation with soot particles, then high nitric oxide emissions. So are owners of new gasoline cars environmentally friendly? Not always, says a new study led by Empa scientists: some direct-injection gasoline engines emit just as many soot particles as unfiltered diesel cars did in the past. Particle filters can remedy this.
A new study has found that children, especially boys, whose mothers were exposed to higher levels of outdoor particulate air pollution at the same time that they were very stressed were most likely to develop asthma by age six. The study was presented at the 2017 American Thoracic Society International Conference.
High levels of air pollution over time may get in the way of a good night’s sleep, according to new research presented at the ATS 2017 International Conference. “Prior studies have shown that air pollution impacts heart health and affects breathing and lung function, but less is known about whether air pollution affects sleep,” said lead author Martha E. Billings, MD, MSc, assistant professor of medicine at the University of Washington. “We thought an effect was likely given that air pollution causes upper airway irritation, swelling and congestion, and may also affect the central nervous system and brain areas that control breathing patterns and sleep.”

On Tuesday, May 23, 2017, the American Thoracic Society will lead ATS members, pulmonary clinicians, researchers, and patient advocates in the ATS Rally on Capitol Hill: Lab Coats for Lungs. The rally will bring attention to recent policies that threaten to undermine many of the ATS’s advocacy priorities including: research funding, tobacco regulation, affordable health care, and clean air.
Man-made pollution in eastern China’s cities worsens when less dust blows in from the Gobi Desert, according to a new study. That’s because dust plays an important role in determining the air temperatures and thereby promoting winds to blow away man-made pollution. Less dust means the air stagnates, with man-made pollution sticking around longer.
