【 摘 要 】

Today, environmental health research on toxicological adverse effects of metal-inorganic materials diffused by cigarettes represents a new challenge for assessing new health risks directly related to the critical chemical-size features of the particles. Therefore, morpho-chemical analyses of hazardous particles become critical in response to the distinctive assumptions about the origin, evolution, and coexisting phases. Here, we report a detailed investigation through direct microscopy imaging of metal-inorganic contaminants for one traditional and two heat-not-burn commercial cigarettes of three different brands. Chemical-size studies revealed the critical presence of heavy metal-inorganic nanostructured microparticles on both paper and filter components of the cigarette, before and after smoking. The direct experimental imaging evidenced on how hazardous particles evolved in mass-size forming coexisting multi-phases of large agglomerate because of the persistence and accumulative effect of the heating puffing. The estimated porosity of the unsuitable engineered filters validated the allowed migration of micrometric pollutants independently from their intrinsic size-shape property. Furthermore, the inappropriate design of the filters made it an adverse sponge reservoir capable of collecting all possible hazardous chemical agents potentially toxic. These substantial results strongly support experimentally the tremendous effect of the smoke capable of transporting and manipulating a high amount of elusive particles, as a particles heat carrier.
