The aim is to bring transparency and insight to an area that has historically been under-researched, but which has now been thrown into the spotlight with ever-heavier vehicles and rapidly cleaning tailpipes. Emissions Analytics is looking to talk to anyone interested in research in this area.
Our findings provide unprecedented insights of the long-term net impacts of aerosols on clouds and precipitation. In polluted air, more and smaller drops are formed. The rain that is withheld in moist, polluted, deep clouds freezes at higher altitudes to form ice crystals or even hail. —Li et al. —Prof.
de novo rather than as direct emissions—via nucleation and growth is a major source of aerosol pollution in terms of number concentration. In spite of a great deal of research, it is still a puzzle why and how such new particule formation (NPF) occurs in a highly polluted urban atmosphere.
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).

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. Nieuwenhuijsen et al. Nieuwenhuijsen et al.
About a third of the airborne lead particles collected at two sites in the San Francisco Bay Area came from Asia, a finding that underscores the far-flung impacts of air pollution and heralds a new way to learn more about its journey across vast distances. We can use this information to guide the development of particulate transport models.
The pollution project, named DeepAir (Deep Learning and Satellite Imaginary to Estimate Air Quality Impact at Scale), is led by Berkeley Lab researcher Marta Gonzalez, who is also a professor in UC Berkeley’s City & Regional Planning Department. —Marta Gonzalez.
This insight could potentially inform bioremediation efforts in the region. Pollution from petroleum hydrocarbons such as diesel, which is widely used for heating, transportation and power generation poses a threat to wildlife in Antarctica. An open-access paper on the work appears in the journal Microbial Cell Factories. Habib et al.
The benefits with battery electrification are significant, including eliminating emissions in operations, reducing noise pollution, and lowering costs by lessening the need for ventilation and cooling when required; this is especially important as underground mines keep getting deeper.
SensorComm’s IoT capability will capture real-time NO x emissions data from a fleet of vehicles, and the resulting analytics will begin the process of baselining and understanding the variety of pollution footprints to provide insights into the most effective mitigation path forward. Global rollout is underway.
The research is the first epidemiological study to provide evidence that ozone might advance subclinical arterial disease—injuries that occur to the artery walls prior to a heart attack or stroke—and provides insight into the relationship between ozone exposure and cardiovascular disease risk. —Meng Wang. —Meng Wang.
The US Environmental Protection Agency (EPA) announced $5,959,842 million in research funding to nine institutions to improve air quality models used to simulate ozone, particulate matter (PM), regional haze, air toxics, and emerging pollutants. It will also inform the development of strategies for improving air quality.
Second, they found that while much of the air pollution policies have focused to date on the electricity sector, damages from farms are now larger than those from utilities. Indeed, farms have become the largest contributor to air pollution damages from PM2.5 related emissions. Tschofen et al. —Tschofen et al.
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.
The valuable insight and hands-on experience that Watsontown will gain by operating the battery-electric trucks for its NRV supply routes will contribute to the company’s future battery-electric truck deployments plans and support their sustainability goals.
It emits 44% less global warming pollution than its closest conventional counterpart, the Toyota Matrix, and its hybrid drivetrain costs a little more than $3,000. The Honda Insight, conversely, has no forced features, delivers more than 40 miles per gallon, and emits relatively little global warming pollution.
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.
results indicate that traffic is the dominating source of BC and particulate air pollution in the metropolitan area of La Paz/El Alto. Soot particles from combustion processes significantly contribute to air pollution because they contain heavy metals and polycyclic aromatic hydrocarbons which are toxic.
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.
from an environmental viewpoint, because 1 L of diesel fuel contains more carbon than 1 L of gasoline and because diesel-powered cars emit more pollutants such as nitrogen oxides (NO x ) and particulates [but less carbon monoxide (CO) and non-methane volatile organic compounds (NMVOCs)], diesel fuel should be more taxed than gasoline.
