Abstract
In connection with the active production development and nanomaterials use, a new urgent task has appeared - the determination of the potential harm of nanoparticles to human health. This article analyses the influence of nanoparticles formed as a result of the extraction, processing and transportation of granite crushed stone. The paper presents data from an industrial survey of ventilation systems and the results of dust analysis of crushed stone production at the Angasolskoye field in the Irkutsk Region, which stands out at different stages of the technological cycle for producing granite crushed stone. Based on the results of the dispersion analysis of granite dust, functional dependences of the integral distribution over the equivalent size of dust particles are given. The main sources of small dust particles (nanoparticles) in the environment are determined.
