Graphene-based nanomaterials (GBNs) possess unique physicochemical properties, allowing a wide range of applications in physical, chemical, and biomedical fields. Although GBNs are broadly used, information about their adverse effects on ecosystem health, especially in the terrestrial environment, is limited. Therefore, this study aims to assess the toxicity of two commonly used derivatives of GBNs, graphene oxide (GO) and reduced graphene oxide (rGO), in the soil invertebrate Enchytraeus crypticus using a reduced full life cycle test. At higher exposure concentrations, GO induced high mortality and severe impairment in the reproduction rate, while rGO showed little adverse effect up to 1000 mg/kg. Collectively, our body of results suggests that the degree of oxidation of GO correlates with their toxic effects on E. crypticus, which argues against generalization on GBNs ecotoxicity. Identifying the key factors affecting the toxicity of GBNs, including ecotoxicity, is urgent for the design of safe GBNs for commercial purposes.

Household electric blankets are widely used in China, but the problem of quality and safety is also more prominent, which is a serious threat to the health and safety of consumers. The structure characteristics and working principle of household electric blanket are analyzed. The hazards in the each stage of full life cycle are identified, including the stages of designing, manufacturing, packaging, transporting, utilizing and recycling. Hazard identification of each stage is made with methods of scenario analysis, safety check list, fault hypothesis analysis, hazard and operability analysis, failure mode and effect analysis and fault tree analysis, respectively.
