Carbon Nanoparticles from diesel engine inhibit lung surfactant
8 September 2008Researchers at University of Michigan simulated a study on the behavior of carbon nanoparticles emitted by diesel engines. Researchers found that the carbon nanoparticles inhaled by people along with the air behaves differently than other foreign particles.
Computer simulated studies carried out by researchers showed that these nanoparticles are ultimately trapped n a lung surfactant fluid, which contains protein and lipid molecules. The earlier studies carried out on nanoparticles shows that if these particles accumulated in lung, these can lead to change in breathing and heart rate, inflammation and other common respiratory disease, however this is the first study conforming that the trapped nanoparticle in lung can affect the behavior of lung surfactant.
The computer simulation model can also predict various other harmful combustion products, the size and other attributes of nanoparticles and their individual affect on lungs. According to researchers the computer simulation will therefore help in engineering biofuel molecule.
