Pentachlorophenol causes energy deficiency and liver injury in marine medaka (Oryzias melastigma) through damaging mitochondria and inducing oxidative stress.

Pentachlorophenol (PCP) is widely distributed in marine environments and poses a threat to the health of marine organisms. Recent studies have demonstrated that PCP induces energy deficiency in marine organisms. However, the underlying toxification mechanism and the resulting adverse outcomes remain unclear.

Effect of 4-n-nonylphenol and cadmium co-exposure on liver apoptosis and lipid metabolism in zebrafish (Danio rerio).

Nonylphenol (NP), a typical nonionic surfactant intermediate, is widely found in aquatic environments and exhibits biological toxicity. In aquatic environments, organisms face risks from co-exposure to NPs and the heavy metal cadmium (Cd); however, the combined toxicity of both has not been well studied. Therefore, this study aimed to evaluate the histological changes, antioxidant capacity, inflammation, and transcriptional responses in the zebrafish liver following exposure to environmental concentrations of 4-n-NP (45.

Enhanced Adsorption of Hexavalent Chromium from Aqueous Solutions by Iron- manganese Modified Cedarwood Biochar: Synthesis, Performance, Mechanism, and Variables.

Three modified biochar (Cunninghamia lanceolata) with iron and manganese elementals (FMBCs) were successfully prepared and used to remove hexavalent chromium (Cr(VI)) from aqueous solutions. The biochar before and after decoration were characterized by advanced instruments. The adsorption capacities of modified biochar in different Cr(VI) (20 mg·L, 1 mg·L) solutions were 4868.

Removal of antimonite and antimonate in aqueous solution by mugwort biochar modified by Acidithiobacillus ferrooxidans after pyrolysis.

In the research, iron oxides-biochar composites (ALBC) were prepared from pristine biochar modified by Acidithiobacillus ferrooxidans (A. ferrooxidans) and pyrolyzed at 500 °C and 700 °C in order to remove antimonite (Sb(III)) and antimonate (Sb(V)) from water. The results indicated that biochar prepared at 500 °C and 700 °C (ALBC500 and ALBC700) were loaded with FeO and FeO, respectively.

Spatiotemporal variations and bioaccumulation of per- and polyfluoroalkyl substances and oxidative conversion of precursors in shallow lake water.

Per- and polyfluoroalkyl substances (PFAS) in water and fish from Nansi Lake, Chian and in inflowing tributaries and nearby sewage treatment plants (STPs) were determined to evaluate their distribution and bioaccumulation. The potential precursors of perfluoroalkyl acid (PFAA) present in the water were converted via hydroxyl radical oxidation. Over 3 seasons, the average concentration ranges of the 15 PFAA (∑PFAA) concentrations in Nansi Lake, inflowing tributaries, and STPs were 22.
