U Vienna team finds stable metabolized TWP-derived compounds with unknown toxicities in lettuce

Green Car Congress

Researchers at the University of Vienna (Austria) have demonstrated that tire wear particle (TWP)-derived compounds are readily taken up by lettuce with measured maximum leaf concentrations between ∼0.75 for N-phenyl-N′-(1,3-dimethylbutyl)-p-phenylenediamine (6PPD) and 20 μg g –1 for hexamethoxymethyl melamine (HMMM). 2c05660.

Toyota develops tropospheric ozone-concentration simulator for South and East Asia

Green Car Congress

have developed a simulator able to predict tropospheric ozone concentrations across the whole of South and East Asia. The project was carried out in collaboration with Tsinghua University in China, The Energy and Resources Institute (TERI) in India, and the International Institute for Applied Systems Analysis (IIASA) in Austria.

International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. Ozone, a key component of smog and also a greenhouse gas, damages crops and human health. Tropospheric ozone and black carbon (BC) contribute to degraded air quality and global warming. —Shindell et al. Drew Shindell, Johan C.

DISCOVER-AQ project to begin flights to enhance measurement of ground-level air-quality from space

Green Car Congress

In the air, NASA investigators will be joined by colleagues from the National Center for Atmospheric Research, the University of California-Berkeley, and the University of Innsbruck in Austria. Both aircraft will measure ozone and a mixture of soot and PM. As a result, questions remain about the vertical distribution of pollutants.

COVID-19 Forced Us All to Experiment. What Have We Learned?

Resources then move from the weaker to stronger entities, and average productivity increases. For example, when China entered world markets as a major exporter of industrial products, production from less productive firms in Mexico was reduced or ceased altogether, thus diverting resources to more productive uses.

Study finds climate impact of long distance trip can vary by factor of 10 depending upon mode, efficiency and occupancy

Green Car Congress

A team from Austria and Norway has found that the climate impact from a long-distance trip (500–1,000 km, or 310–621 miles) can easily vary by a factor of 10 per passenger depending on mode choice, vehicle efficiency, and occupancy.
