Battling flames increases firefighters' exposure to carcinogens

The threat of getting burned by roaring flames is an obvious danger of firefighting, but other health risks are more subtle. For example, firefighters have been found to develop cancer at higher rates than the general population. ...

Antibody against carcinogenic substance deciphered

Summertime is barbecue time. However, when fat reacts with glowing coal, a substance chemists call benzopyrene is created. It is a widespread environmental toxin that can cause cancer in humans. Since buildings were heated ...

Molecular libraries for organic light-emitting diodes

The rising demand for increasingly sophisticated smartphones, tablets and home cinemas is a growing challenge for display technology. At present, organic materials are the most effective way to master this challenge. In particular ...

Less is more when it comes to soot

Small particles emitted into air during the burning of hydrocarbon fuels damage the human respiratory system and enhance the greenhouse effect. In their agglomerated form, these particles form soot that consists predominantly ...

Surprisingly complex fingerprint of PAH molecules in space

Astronomers searching for interstellar PAH-molecules interpret their data incorrectly. This is concluded by researchers from the University of Amsterdam (UvA), the Leiden Observatory, the Radboud University and NASA Ames ...

New technology tracks carcinogens as they move through the body

Researchers for the first time have developed a method to track through the human body the movement of polycyclic aromatic hydrocarbons, or PAHs, as extraordinarily tiny amounts of these potential carcinogens are biologically ...

Pavement sealcoat a source of toxins in stormwater runoff

Driveways and parking lots may look better with a layer of sealcoat applied to the pavement, but the water running off the surface into nearby streams will be carrying more than just oxygen and hydrogen molecules. New research ...

Mars Rover device gets new mission on Earth

Developed to sniff out extraterrestrial life on other planets, a portable device known as the Mars Organic Analyzer (MOA) is taking on a new role in detecting air pollutants on Earth. Researchers in California report the ...
