The ceramics industry,resulting from developments of modem compounds,is a segment of great influence in worldwide sustainability.Artisanal ceramic factories based on wood combustion have significant risks for the creation and discharge of atmosphere nanoparticles (NPs) and ultra-fine particles (UFPs).At present,there is in-sufficient recognition on the influence of engineered-NPs on the atmosphere and health.Real improvements are indispensable to diminish contact with NPs.The present study demonstrates the main NPs and UFPS present in an area of intense artisanal wood-combustion ceramic manufacturing.Particulate matter was sampled for mor-phological,chemical,and geochemical studies by sophisticated electron microbeam microscopy,X-Ray Diffrac-tion,and Raman spectroscopy.From NPs configuration (＜10 nm) we identify nucleation.Several amorphous NPs (＞10 nm) were produced around the studied artisanal ceramic factories.This study presents an indication of the recent information on population and work-related contact to NPs in the artisanal ceramic factories and their influence on health.
