Researchers in the group under Salvador Pané i Vidal, Professor at ETH Zurich’s Institute of Robotics and Intelligent Systems, have developed a new method to break down a subgroup of PFAS called perfluorooctane sulfonates, or PFOS. Due to their toxicity, PFOS are now severely restricted or eve...
The bioaccumulation and toxicity of per- and polyfluoroalkyl substances (PFAS) have raised scientific and public concern in recent decades, leading to regulatory measures for some PFAS (e.g. perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA)). In addition, the discovery of new ...
Phytoremediation Potential of Azolla filiculoides: Uptake and Toxicity of Seven Per‐ and Polyfluoroalkyl Substances (PFAS) at Environmentally Relevant Wat... Environmental contamination of aquatic systems by per‐ and polyfluoroalkyl substances (PFAS) has generated significant health concerns. Remediation...
摘要: PROBLEM TO BE SOLVED: To provide a stable exposure mask blanks and a mask in which connection between a support frame and a reinforcing member is superior and which have high flatness, and to provide a method of manufacturing the same....
Due to the complex composition of dye wastewater, it is difficult to degrade, which contains a large number of macromolecules. Some dyes have high toxicity and strong carcinogenicity. And unreasonable discharge will be harmful for the environment and human body (Ghosh et al. 2020). Nowadays, ...
Studies on toxicity for this species are rare and primarily focus on the influence of water-soluble substances on juvenile survival (Belamy et al., 2020, Bílý et al., 2018, Taskinen et al., 2011). Based on studies of sediment-related adverse effects on other bivalve species and benthic...
For direct hydrazine fuel cells, the high toxicity of hydrazine is the main problem, even though a method for storage has been developed to store hydrazine in a solid form [100]. Direct sodium borohydride fuel cells suffer from the same problem as AFCs because they include sodium [101]. ...
Due to the large number of PFAS compounds, investigation and research are still ongoing to understand the many aspects of their toxicity and their effects on humans.PFAS Analysis Given the above circumstances, there is a need for PFAS analysis. LC-MS/MS is currently the main system used for ...
The experimental results using a laboratory rotating-cylinder method demonstrated that biocide-free paints did not markedly affect three species tested and no PFAS was detected. In contrast, biocide paint was significantly toxic to test species and toxicity of the extract on bacteria was partly ...
CARBOXYLIC acidsFOOD packagingDETECTION limitPoly- and perfluoroalkyl substances (PFASs) have attracted great scientific attention because of their environmental persistence, bioaccumulation potentials, and toxicity. This study validated a simple and efficient sample preparation method for determining extractable ...
