Use of Honey Bees and Hive Products as Bioindicators to Assess Environmental Contamination in Targeted Areas of the Campania Region (Italy).

In recent years, biomonitoring has gained more attention, particularly when assessing the environmental health of significant areas, such as those near waste-to-energy facilities. These requirements coincide with the chance to detect environmental pollutants using sensitive organisms. Bees were shown to be quite effective in evaluating the presence of certain compounds by analyzing their associated matrices, such as pollen, honey, or wax.

Ecotoxicological assessment of water phase exfoliated two-dimensional Group-VI transition metal dichalcogenides using zebrafish embryo model.

Among emerging layered materials, 2D transition metal dichalcogenides (TMDs) nanosheets (n-sheets) have received increasing attention for optoelectronics, energy storage, and, recently, for bioremediation and advanced biomedical applications; however, a lack of ecotoxicological in vivo studies is evident. Herein, for the first time, the potential nanotoxicity of liquid phase exfoliated Group VI TMDs n-sheets (MoS, WS, WSe, and MoSe) was comparatively investigated using zebrafish embryos (Z-EBs) as an in-vivo model. The 2D n-sheets were produced directly in aqueous-medium, the obtained n-sheets were characterized by scanning electron microscopy, Raman and visible spectroscopy, and their potential nanotoxicity was investigated by fish embryo test OECD TG 236.

Personal Care Products as a Contributing Factor to Antimicrobial Resistance: Current State and Novel Approach to Investigation.

Antimicrobial resistance (AMR) is one of the world's industrialized nations' biggest issues. It has a significant influence on the ecosystem and negatively affects human health. The overuse of antibiotics in the healthcare and agri-food industries has historically been defined as a leading factor, although the use of antimicrobial-containing personal care products plays a significant role in the spread of AMR.

Oxysterols profiles in zebrafish (Danio rerio) embryos exposed to bisphenol A.

Introduction: Oxysterols are cholesterol oxidation products and bioactive lipids involved in developmental signalling pathways, embryonic and postembryonic tissue patterning and homeostasis. The embryonic period is a very sensitive window of exposure to bisphenol A (BPA), hence the role of BPA on the levels of oxysterols in the very early stages of zebrafish embryogenesis is a relevant novel field of investigation.

Objectives: To compare the role of BPA on oxysterols levels in zebrafish embryos at 8 and 24 h post fertilization (hpf) with cytochromes P450 (CYPs)-modulating chemicals (carbamazepine, ketoconazole, and hydrogen peroxide).
