Urban planners should plant hedges—or a combination of trees with hedges—rather than just relying on roadside trees if they are most effectively to reduce pollution exposure from cars in near-road environments, according to a new study from the University of Surrey.
A new study has found that pollutant particles carried by these flows prefer to accumulate in specific regions of the urban environment and even form coherent structures, rather than scattering randomly. It was not known if such structures were robust enough to manifest in the environment.
New research by George Mason University found that exposure to certain air pollutants is linked to increased emergency department (ED) visits for respiratory and cardiovascular diseases. The study is published in the journal Environment International. We estimated associations between twelve ambient air pollutants of both primary (e.g.

By disrupting normal societal activities such as driving, COVID-19 lockdowns afforded a unique opportunity to study their impacts on the environment. On a national or global scale, most NH 3 pollution comes from agricultural sources, such as livestock manure. Bowman, Tzung-May Fu, and Muhammad O. 1c00730.
It would be many decades before it would slow down global warming at all, and even then it would just be making a difference around the edges. The burning of coal releases more carbon dioxide than other fossil fuels, as well as comparatively high levels of other pollutants, including sulfur dioxide, nitrogen oxides, and particles such as ash.

From Zheng et al. 2020.117451.
An in-house study by environmental NGO Transport & Environment (T&E) has found that the luxury cruise brands owned by Carnival Corporation & PLC emitted in 2017 in European seas alone 10 times more SO x than all of Europe’s 260+ million passenger vehicles. million passenger vehicles in a year.
The United Nations Environment Programme (UNEP) estimates that 1,960 tonnes of mercury arising from human activities are currently emitted annually into the atmosphere, generated mainly by artisanal and small-scale gold mining (ASGM)—the largest single anthropogenic source globally—and coal- or lignite-fired power plants.
Exposure to air pollution, even over the course of just a few weeks, can impede mental performance, according to a new study led by researchers at Columbia University Mailman School of Public Health. The study is among the first to explore short-term air pollution exposures and the use of NSAIDs to mitigate their effects.
The new metamodel is capable of efficiently simulating the urban concentration, surface deposition, and net export flux of these species that are important to human health and the global climate. Urban regions account for an ever increasing fraction of Earth’s population, and are consequently an ever increasing source of air pollutants.
The United Nations Environment Programme (UNEP) and partners have launched a new initiative that aims to reduce pollution levels, improve resource efficiency and reduce infrastructure costs in cities across the world. Up to 80% of the world population is expected to reside in cities by 2050.
Car users from the world’s least affluent cities are exposed to a disproportionate amount of in-car air pollution because they rely heavily on opening their windows for ventilation, according to a new global study led by researchers at the University of Surrey. In-Car Particulate Matter Exposure across Ten Global Cities.”

trillion is spent annually on transport globally, mostly in ways that exacerbate rather than solve the problems associated with traffic growth, including congestion, health-harming air pollution, accidents, energy insecurity, and climate change. Transportation is central to the social and economic activity of people across the world.
Information will be uploaded to Maersk Line servers via satellite, and each ship will be able to communicate in real-time with Maersk Line’s Global Vessel Performance Centre (GVPC) to increase operational efficiency. This advances our ability to reduce greenhouse gases and other pollutants on a global scale.
Global levels of the hydrocarbons ethane and propane in the atmosphere have been underestimated by more than 50%, according to a new study by a team of scientists from Europe and the US. Levels of ethane and propane declined in many places the 1980s and 1990s, but global growth in demand for natural gas means these trends may be reversing.
