Power plants produce more ultrafine dust than traffic

Ultrafine particles affect both health and climate. In urban areas, road traffic is considered to be the main source of the small particles. However, a long-term measurement campaign of researchers of Karlsruhe Institute ...

Carbon nanodots do an ultrafine job with in vitro lung tissue

Epidemiological studies have established a strong correlation between inhaling ultrafine particles from incomplete combustion and respiratory and cardiovascular diseases. Still, relatively little is known about the mechanisms ...

Healthier air due to the low emission zone

The low emission zone in Leipzig was established in March 2011, allowing only diesel vehicles of Euro4 and higher with few exceptions. The ban of older vehicles and subsequent modernization of the car fleet resulted in slightly ...

Tiny particles increase in air with ethanol-to-gasoline switch

The concentration of ultrafine particles less than 50 nanometers in diameter rose by one-third in the air of São Paulo, Brazil, when higher ethanol prices induced drivers to switch from ethanol to gasoline, according to ...
