March 21, 2020 was the ridgeline between the growth of the coronavirus disease 2019 (COVID-19) epidemic wave in Italy and the start of its decline. We analyzed the epidemic patterns from March 1 to June 30. There was a progressive drop of cases from March (104,710) to April (94,888), May (25,705) and June (8110). Likewise, after a slight...

Freshwater and marine water bodies receive chemical contaminants from industrial, agricultural, urban, and domestic wastes. Eco-genotoxicity assays are useful tools to assess the cumulative genotoxicity of these pollutants. Fish are suitable indicators for biomonitoring of mutagenic and carcinogenic pollution. In this review, we present a...

COVID-19 may cause pneumonia, acute respiratory distress syndrome, cardiovascular alterations, and multiple organ failure, which have been ascribed to a cytokine storm, a systemic inflammatory response, and an attack by the immune system. Moreover, an oxidative stress imbalance has been demonstrated to occur in COVID-19 patients. N-...

The term asbestos refers to a group of serpentine (chrysotile) and amphibole (amosite, crocidolite, anthophyllite, tremolite and actinolite) minerals with a fibrous habit. Their chemical-physical properties make them one of the most important inorganic materials for industrial purposes and technological applications. However, the extraction,...

Microbial-based cleaning products (MBCPs) have been introduced, on the market, as an alternative to traditional chemical cleaning. In addition to traditional detergents, MBCPs can perform their cleaning function, digesting the smallest particles of dirt and mitigating odours generated by environmental bacterium metabolic processes....

Inhalation of asbestos fibres can cause lung and pleural diseases in humans and constitutes a severe public health threat worldwide. The aim of the present study was to assess the biological effects induced in both pulmonary cells (A549) and monocyte/macrophage (RAW 264.7) cell lines by combustion slags obtained from asbestos through a...

In spite of the overwhelming epidemiological evidence for cigarette smoke (CS) carcinogenicity, less attention has been paid to the effects of CS as a complex mixture. As assessed in a series of experiments in murine models, the whole-body exposure to mainstream CS induced significant increases of micronucleated cells in the respiratory tract,...

Titanium is the ninth most abundant element, approximately 0.7% of the Earth crust. It is used worldwide in large quantities for various applications. The IARC includes TiO2 in Group 2B as possibly carcinogenic to humans suggesting that pathological effects correlate to particle size and shape. This study case quantifies the release of natural...

Due to their morphological and physicochemical properties, carbon nanotubes (CNTs) enhance the structural properties of several materials and are produced in great volumes. The production and the manufacturing of CNTs-incorporated products can lead to the potential environmental release of CNTs. For these reasons, CNTs can represent a serious...
