- Assessment of airborne nanoparticles emissions in the ceramic industryPublication . Esteves, H.; Gomes, João; M. Miranda, R.; Albuquerque, P.The aim of this study was to evaluate the occupational exposure to nanoparticles during the tasks performed in various jobs in the production processes of the national ceramic industry, analyze the collected data and seek to understand the specific occupational exposure situation of the workers in this sector. The study was developed in three different national production plants of ceramic, one of sanitary production, another of refractory bricks and another of ornamental ware (red paste). It is concluded that the values of occupational exposure to nanoparticles are high in all cases and that the nanoparticles are of very small size, with a strong capacity for alveolar penetration and, consequently, with a strong possibility of passing into the bloodstream, accumulating in the body.
