THE PARTICULATE MATTER IN THE WORKING ENVIRONMENT OF THE DIGITAL PRINTING MACHINE DETECTED BY STATIONARY AND PERSONAL METHODS

Particulate matter (PM) emitted during the digital printing process is potentially dangerous in the sense that it penetrates deep into the operator's lungs. The mass concentration levels of PM1, PM2.5, and PM10 particles emitted in the working environment of digital machines were measured after applying two sampling methods, spatial and individual. A sensor sampler with an optical particle counter was used for the spatial method, while a personal sampler of particulate materials was applied for the individual process. The paper's primary goal is to assess the comparability of the concentration of PM particles obtained by different sampling methods.
