Particulates - Ever tinier particles are coming under the researchers’ microscopes 18 March 2005 - UFZ - Centre for Environmental Research (Umweltforschungszentrum Leipzig-Halle) You can’t smell them, you can’t taste them and particulates are not visible to the naked eye. They are tiny, with a diameter not even a tenth of that of a hair. Yet they have a major impact. Particulates - ever tinier particles are coming under the researchers’ microscopes 18 March 2005 - UFZ - Centre for Environmental Research (Umweltforschungszentrum Leipzig-Halle) Scientists fear that the most dangerous particles are even smaller than PM10, particles with a diameter of less than 10 micrometres. Currently there are neither limit values nor a monitoring network for such particles. These ultrafine particles are smaller than 100 nanometres, that is less than one ten millionth of a metre.
