During the SARS-Cov-2 pandemic, a test of samples collected through naso/oropharyngeal swab was set up; for this aim new swabs were developed. Materials and methods: The laboratory New Nanodiagnostics srl (Modena - Italy) analyzed nine different types of swabs used to collect human organic material for PCR diagnostic test for the SARS-CoV-2 infection. The swabs were observed under Optical Microscope and analyzed by Field Emission Gun Environmental Scanning Electron Microscope (FEGE-SEM) coupled with an Energy Dispersive System (EDS), to verify their morphology and chemical composition. Three different morphologies and nanostructures, along with their chemical composition were identified. Surprisingly enough, the presence of identified chemical contaminants like Titanium-Silicon-Aluminum or Silicon- Aluminium-Chromium-Manganese does not be understandable nor is it explained in the data sheet. Some fibers also present a nanostructured coating of Silicon-Zirconium. This might be of concern, as their presence could invalidate the accuracy of the PCR testing. In addition to that, the biocompatibility of the medical devices is discussed since a particular tendency of the glassy fibers to break has been verified. The presence of broken fibers in the nasal and oropharyngeal mucosa can cause irreversible damages. Finally, after their use, the swabs must be incinerated and their fumes contribute to the increase of the environmental pollution.

We report, for the first time, the surprising presence of toxic nanoparticles, especially silver, in the brain of a fetus, who died unexpectedly at the end of a regular pregnancy. After an accurate autopsy, including the examination of the fetal annexes, an in-depth anatomopathological study of the nervous system and a search by scanning electron microscopy of nanoparticles in the brain, we highlighted the sequence of events that may have led to this fetal death, triggered primarily by the transition of nanosized xenobiotics from the mother to the fetal bloodstream. From this report emerges the importance of considering the search of nanosubstances in the brain during routine investigations following unexpected and unexplained fetal and infant deaths.

... In 2023 and colleagues studied nine different PCR swabs for their morphology and chemical composition, using Optical Microscopy and a Field Emission Gun Environmental Scanning Electron Microscope with Energy Dispersive System. [89] The scientists reported a number of substances on the swabs that had not been declared in the manufacturers' data sheets. Those substances included black fibres that were present "in an almost systematic way", silver nanoparticles, coatings on the swab fibres involving different combinations of Silicate, Zirconia, Titanium, Aluminium and Sulphur, and "extremely high" levels of what the authors described as "dust". ...

... Humans ingest NPs mainly through the mouth and skin, and nanoscale particles appear to be more reactive and toxic compared to larger particles [68]. NPs inhaled into the lungs can be transported to other organs, including the brain [69], liver [70], and spleen [71], and even penetrate the placental barrier into the fetal side, adversely affecting fetal development and even the growth of the infant after birth [72]. Numerous studies have shown that NPs are associated with the development of cardiovascular disease. ...

... The second most abundant pollutant resulting from grilling fish using charcoal is particulate matter. Particulate matter has been declared carcinogenic by the International Agency for Research on Cancer, including emissions from household fuels such as wood and charcoal (Visani et al., 2015). Particulate matter exposure can induce the production of reactive oxygen species (ROS) which can activate pro-inflammatory and pro-thrombotic pathways, produce endothelial dysfunction, increase blood coagulation and the development of cardiovascular disease (Hamanaka and Mutlu, 2018). ...

... Our findings, however, are bolstered by their parallel analysis of the fluids in vials of the mRNA concoctions alongside centrifuged plasma samples from the cases they studied intensively. What seems plain enough is that metallic particles resembling graphene oxide and possibly other metallic compounds, like those discovered by Gatti and Montanari (Montanari & Gatti, 2016;Gatti & Montanari, 2012, 2017, 2018, have been included in the cocktail of whatever the manufacturers have seen fit to put in the so-called mRNA "vaccines". In our experience as clinicians, these mRNA injections are very unlike traditional "vaccines" and their manufacturers need, in our opinions, to come clean about what is in the injections and why it is there. ...

... Physical contamination of food can occur at different processing stages and is characterized by the presence of foreign objects in the food. For example food can be contaminated with insects and animal droppings as well as fragments of different materials (e.g., wood, glass, and plastic) (Kamala & Kumar, 2018) and air-polluting residues (Gatti & Montanari, 2018). Stones, hair, metal, rubber, and insects are also considered physical contaminants. ...

... Individuals with 2-5 years of exposure to PM 2.5 pollution had a mean decline in hemoglobin levels of 0.81 ± 0.06 g/ dL 155 . The PM 2.5 levels in blood samples from adult patients (age 20-71 years) were higher in those with acute myeloid leukemia than in healthy individuals 156 . Exposure of newborn mice to PM 2.5 induced HSC senescence by causing chronic oxidative stress and inflammasome activation in the BM 76 . ...

... Investigations are also needed on the applicability and efficiency of this material for soil remediation purposes under field conditions. Nanoparticles have been criticized to cause health problem (Gatti and Montanari 2008;Seaton 2007). The characteristics of nanoparticles that influence toxicity is included the number, size, surface area, shape, solubility, chemical composition, and chemical reactivity (Marconi 2006). ...

... In recent decades, researchers have also acknowledged the fundamental toxic role of nanomaterials (i.e., ultrafine particles with dimensions under 100 nm), which are widely used in biomedicine, biotechnology and the environmental industry [39,40]. Therefore, nanotechnology, which are increasingly employed due to their potential in the creation of new therapies and diagnostic tools, could be considered a serious hazard to human health [41]. ...
