Håkan Tinnerberg, associate professor at Occupational and Environmental Medicine, is now receiving funding from AFA Insurance to measure and analyze the content of elemental carbon and soot particles in the form of Black carbon in diesel exhaust in a laboratory environment and in a work environment. Measuring soot particles in the form of elemental carbon requires equipment that is only available at a few of the country’s universities, while Black carbon is much easier to measure. If the measurement of Black carbon can be correlated to elemental carbon, it would provide a simpler method for assessing exposure to diesel exhaust gases. The project will also provide measurement data that can be used for risk assessment for some specific occupational groups.
