When airborne particles (green) form before PAHs adhere, both the pollutants and particles dissipate quickly, as shown in the top row. But when the particles form in the presence of pollutants, which is what likely happens in nature, the longer-lasting particles enable the long-range transport of the pollutants (bottom).
Our findings provide unprecedented insights of the long-term net impacts of aerosols on clouds and precipitation. They can be hazardous to both human health and the environment. In polluted air, more and smaller drops are formed. This explains why air pollution can exacerbate both drought and flood. —Li et al.

The European Environment Agency’s (EEA) data confirm large decreases in air pollutant concentrations—of nitrogen dioxide (NO 2 ) concentrations in particular—largely due to reduced traffic and other activities, especially in major cities under lockdown measures. Reductions of around half have been seen in some locations.
Air pollution varies widely over the course of a day and by location, even within the same city. Now scientists, reporting in the ACS journal Environmental Science & Technology , have used smartphone and sensing technology better to pinpoint where and when pollution is at its worst.

To be truly effective, EPA’s environmental research must evolve along with these new insights and be as dynamic as the challenges it aims to inform. All of EPA’s actions and decisions are based on science and research.
However, this alone will not drive the widespread change needed to really make an impact on the environment, and this challenge cannot be put on the shoulders of motorists alone. The pandemic has seen a wave of strong activism and more conversations around sustainability, which has driven the nation to re-evaluate mobility solutions.
An open-access paper on the work is published in the journal Atmospheric Environment. results indicate that traffic is the dominating source of BC and particulate air pollution in the metropolitan area of La Paz/El Alto. Therefore, air pollution in this region has a particularly strong impact on the atmosphere and the global climate.
Although studies widely agree that widespread deployment of hydrogen fuel cell vehicles and the associated infrastructure would reduce air pollutant emissions from the transportation sector, the extent to which air quality in an urban airshed will be affected by these reductions is a more complex matter than simply quantifying emissions.

This study marks a significant step in understanding the impact of electric cars on public health and the environment.
Two Colorado State University (CSU) researchers have received a $325,000 National Science Foundation grant to determine the pollutant formation chemistry of algae-derived biofuels, which have potential to be high-yield, efficiently produced, renewable fuels. Are there going to be any consequences that we may not have thought about?
Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. Determining effective strategies for mitigating surface ozone (O 3 ) pollution requires knowledge of the relative ambient concentrations of its precursors, NO x , and VOCs.
In some parts of Asia, Africa and South America, the researchers identified data gaps which prevented them from characterizing ozone pollution exposure patterns. However, overall, Southern Hemisphere sites tend to have lower ozone pollution levels, and fewer days above 70 ppb. Source: University of Leicester. Click to enlarge.
Countries seeking to meet Paris Agreement targets on CO 2 emissions must get a grip on the amount of pollution produced at city level, according to a new open-access study published in S cience Advances by an international team of researchers from Europe and China.
This data promises to play an important role in providing cities and local authorities with the insight they need to develop Clean Air Zones and other air pollution mitigation measures. The system can measure emission from thousands of vehicles in a short space of time, without interfering with the vehicle being tested.
Benz Vans, the Österreichische Post and MANN+HUMMEL have launched a pilot project to reduce fine dust pollution and to gain comprehensive insights into effectiveness, weather influences and durability in real-life operation. The effectiveness of filtration increases further with higher levels of particulate matter in the environment.
It also represents an immediate opportunity to improve outcomes for all stakeholders while reducing pollution across towns and cities. The EV program in Nagpur has provided Ola with insights into effectively managing vehicles, batteries, and operations.
Our customers expect us to help mitigate, if not eliminate, issues such as congestion and pollution. Our CDP ranking shows that we’re measuring and pulling insight from our energy and carbon data to capitalize on opportunities for greater efficiency. “It It reinforces our stewardship and sustainability goals. —GM CEO Mary Barra.
While scrappage schemes have the potential to deliver on objectives such as reducing pollutant emissions, these have not done so as well. Further, the study suggests that seeking CO 2 reduction ahead of pollution or safety improvements in the design of the schemes leads to decreased cost-effectiveness and lower overall societal benefit.
GISERA Director Dr Damian Barrett said that the CSIRO research conducted via GISERA in this region was an Australian first and provided unique insights into the impacts of hydraulic fracturing in Australia.
