Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

The researchers say that their findings, recently published in an open-access paper in the journal Science Advances , are key to understanding how the universe evolved with the growth of carbon compounds. That insight could also help the car industry make cleaner combustion engines.

Researchers suggests high level of air pollution in Northern Italy a co-factor in COVID-19 mortality rate

Green Car Congress

Researchers from the University of Siena in Italy and Aarhus University in Denmark are suggesting that the high level of pollution in Northern Italy should be considered an additional co-factor of the high level of COVID-19 fatalities recorded in that area. Environmental Pollution , doi: 10.1016/j.envpol.2020.114465.

Researchers detect broad range of emerging synthetic antioxidants in dust in e-waste recyling centers

Green Car Congress

However, the health effects of these compounds, and how readily they migrate into the environment, are largely unknown. Previous studies revealed widespread environmental pollution and human exposure to a class of compounds called low-molecular weight synthetic phenolic antioxidants. 1c00866.

Researchers find two strains of diesel-eating bacteria in Antarctica

Green Car Congress

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.

Researchers present new explanation for the long-range transport of PAH pollutants

Green Car Congress

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).

Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

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.

Study finds megacity traffic soot can reach high altitudes and be transported over long distances, contributing to global warming

Green Car Congress

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.
