A new in-depth study from Ryerson University called 'The influence of environmental and health indicators on premature mortality: an empirical analysis of the City of Toronto's 140 neighborhoods' assesses the impact of several environmental, health, socioeconomic and demographic characteristics on lifespan. Authors Luckrezia Awuor and Stephanie Melles determined that premature mortality in Toronto neighborhoods was predicted by a combination of unhealthy environments and embedded socioeconomic imbalances.
An unprecedented survey has revealed the loss of about 85 percent of historical tidal wetlands in California, Oregon, and Washington. The report, published today in PLOS ONE, also highlights forgotten estuary acreage that might now be targeted for restoration.
Researchers at the University of Waterloo have integrated the use of blockchain into energy systems, a development that could result in expanded charging infrastructure for electric vehicles.
A higher standard of wastewater treatment in the UK has been linked to substantial improvements in a river's biodiversity over the past 30 years. The Centre for Ecology & Hydrology analysed data from the regular monitoring of both chemicals and invertebrates in the River Ray in Wiltshire -- downstream from Swindon's large wastewater treatment plant - between 1977 and 2016.
Wind plays a role in carrying microplastics (shreds of plastic less than five millimeters long) to both the snowy streets of European cities and remote areas of the Arctic Ocean -- where ecosystems are already stressed by the effects of climate change.
Over the past several years, microplastic particles have repeatedly been detected in sea-water, drinking water, and even in animals. But these minute particles are also transported by the atmosphere and subsequently washed out of the air, especially by snow -- and even in such remote regions as the Arctic and Alps. This was demonstrated in a study conducted by experts at the Alfred Wegener Institute and a Swiss colleague, recently published in the journal Science Advances.
Long-term exposure to air pollution was linked to increases in emphysema between 2000 and 2018, according to a new study funded by the National Institute of Environmental Health Sciences (NIEHS) and the National Heart, Lung, and Blood Institute (NHLBI), both part of the National Institutes of Health.
A new multicenter study at Columbia University links long-term exposure to air pollution, especially ozone, to development of emphysema, accelerating lung disease progression as much as a pack a day of cigarettes.
Whether exposure to outdoor air pollutants is associated with emphysema progression and change in lung function was the focus of this observational study. The study included 7,071 participants from the Multi-Ethnic Study of Atherosclerosis studies conducted in six US metropolitan regions (New York; Los Angeles; Chicago; Baltimore; Winston-Salem, N.C.; and St. Paul, Minn.). Computed tomographic (CT) scans were used to assess changes in emphysema (measured for density as a percentage of lung pixels) and lung function testing was done.
Liyin He, a Caltech graduate student, finds that methane in L.A.'s air correlates with the seasonal use of gas for heating homes and businesses
