Topic: air pollution
Washington, D.C. – NASA says moon dust isn’t like the stuff that collects on a bookshelf or on tables – it’s ubiquitous and abrasive, and it clings to everything. It’s so bad that it even broke the vacuum NASA designed to clean the moon dust off Apollo spacesuits.
With NASA’s return to the Moon and its orbit, it will need to manage the dust, which is dangerous for people too. The first step is knowing how much is around at any given time. Efforts to do just that are already paying off on Earth, in the fight against air pollution.
Washington, D.C. – While scientists around the world are confined to their homes during the COVID-19 Coronavirus pandemic, Earth observing satellites continue to orbit and send back images that reveal connections between the pandemic and the environment. “Satellites collect data all the time and don’t require us to go out anywhere,” Hannah Kerner, an assistant research professor at the University of Maryland in College Park, said.
Kerner is among eight researchers recently awarded a rapid-turnaround project grant, which supports investigators as they explore how COVID-19 Coronavirus lockdown measures are impacting the environment and how the environment can affect how the virus is spread.
Washington, D.C. – Over the past several weeks, NASA satellite measurements have revealed significant reductions in air pollution over the major metropolitan areas of the Northeast United States. Similar reductions have been observed in other regions of the world.
These recent improvements in air quality have come at a high cost, as communities grapple with widespread lockdowns and shelter-in-place orders as a result of the spread of Coronavirus (COVID-19).
American Stroke Association
Dallas, TX – In a nationwide study, counties with dirtier air had higher rates of stroke deaths and shorter life expectancies, according to preliminary research to be presented in Honolulu at the American Stroke Association’s International Stroke Conference 2019, a world premier meeting for researchers and clinicians dedicated to the science and treatment of cerebrovascular disease.
Researchers examined the average yearly levels air pollution (PM2.5) that contains fine inhalable particles.
American Heart Association says In-Womb Air Pollution Exposure associated with Higher Blood Pressure in Childhood
Hypertension Journal Report
Dallas, TX – Children who were exposed to higher levels of air pollution during the third trimester of their mother’s pregnancy had a higher risk of elevated blood pressure in childhood, according to new research in the American Heart Association’s journal Hypertension.
Fine particulate matter of 2.5 microns or less (PM2.5) is a form of air pollution produced by motor vehicles and the burning of oil, coal and biomass, and has been shown to enter the circulatory system and negatively affect human health.
American Heart Association reports Air pollution linked to Cardiovascular Disease; Air Purifiers may lessen impact
Circulation Journal Report
Dallas, TX – Exposure to high levels of air pollution increased stress hormone levels and negative metabolic changes in otherwise healthy, young adults in a recent study conducted in China. Air purifiers appeared to lessen the negative effects, according to new research published in the American Heart Association’s journal Circulation.
Researchers focused on fine particulate matter (PM2.5) – a component of air pollution emitted from vehicles, factories, power plants, fires and smoking – because many studies have suggested this type of major air pollutant might lead to cardiovascular and metabolic health consequences, according to Haidong Kan, M.D., Ph.D., study author and professor of environmental health sciences at Fudan University in Shanghai, China.
American Heart Association says “Bad” air may impact “Good” Cholesterol increasing Heart Disease Risk
Arteriosclerosis, Thrombosis, and Vascular Biology Journal Report
Dallas, TX – Traffic-related air pollution may increase cardiovascular disease risk by lowering levels of high-density lipoprotein (HDL), commonly known as “good” cholesterol, according to new research in the American Heart Association’s journal Arteriosclerosis, Thrombosis, and Vascular Biology.
Air Pollution linked to Blood Vessel damage in Healthy Young Adults according to American Heart Association
American Heart Association Rapid Access Journal Report
Dallas, TX – Fine particulate matter air pollution may be associated with blood vessel damage and inflammation among young, healthy adults, according to new research in Circulation Research, an American Heart Association journal.
“These results substantially expand our understanding about how air pollution contributes to cardiovascular disease by showing that exposure is associated with a cascade of adverse effects,” said C. Arden Pope, Ph.D., study lead author and Mary Lou Fulton Professor of Economics at Brigham Young University in Provo, Utah.
American Heart Association says Household Air Pollution linked to Higher Risk of Heart Attacks, Death
American Heart Association Rapid Access Journal Report
Dallas, TX – Long-term exposure to household air pollution from lighting, cooking or heating with fuels, such as kerosene or diesel, may increase the risk of heart attacks and death, according to new research in the American Heart Association’s journal Circulation.
Burning cleaner fuels, such as natural gas, was associated with a lower risk of cardiovascular deaths.
According to the World Health Organization, one-half of the world’s population lives in poverty and burns fuels for lighting, cooking and heating purposes.

Washington, D.C. – For more than three decades NASA has focused its space-faring skills and science chops CSI-like on an elusive global killer. Later this month, that pursuit takes us to East Asia. In a few years, part way to the moon.
We are getting close.
Air pollution causes an estimated 152,000 deaths a year across the Americas and more than 2 million deaths in the Western Pacific, according to the United Nations. Some parts of the world have a detailed view of local air quality from ground sensor networks and forecast models that generate public alerts. But for much of the world this type of information and warning are not available.
