Ecotoxicity stress and bioaccumulation in Eisenia fetida earthworms exposed to vanadium pentoxide in soil.
Environ Sci Pollut Res Int
April 2023
As an important commercial form of vanadium, vanadium pentoxide (VO) is widely used in various modern industries, and its environmental impacts and ecotoxicity have been extensively studied. In this research, the ecotoxicity of VO to earthworms (Eisenia fetida) in soil was tested by exposure to VO at a series of doses, and biochemical response indices, such as the superoxide dismutase (SOD) and catalase (CAT) enzyme activity and malondialdehyde (MDA) content, were analysed to determine the mechanism by which antioxidant enzymes respond to VO exposure. The bioaccumulation factor (BAF) of vanadium pentoxide in the earthworms and soil was also measured to explore the bioaccumulation process of VO in the test period.

- Phenol is commonly found in various products like insulation materials, adhesives, and paints, but long-term exposure can cause serious health issues, including skin burns and damage to the liver and nervous system.
- The study investigated phenol levels in the water and aquatic products of Poyang Lake, with concentrations ranging from not detected to over 556 ng·L in water and up to 255.51 μg·kg in aquatic products.
- Health risks from drinking water and consuming aquatic products were assessed, showing higher risks in specific areas, particularly for yellow catfish, while the overall phenol concentrations were deemed manageable for public health.
The concentrations and spatial distribution characteristics of 16 US EPA priority Polycyclic Aromatic Hydrocarbons (PAHs) in water bodies in seven basins in China were systematically analyzed and summarized. The acute ecological risks of 8 PAHs to aquatic organisms were evaluated by means of species sensitivity distribution (SSD). The joint acute ecological risks of ΣPAH to aquatic organisms were evaluated by concentration addition model and response addition model.

Objective: To study the extract process of Cyclic adenosinemonophosphate (cAMP) in Ziziphus jujuba.
Methods: CAMP was extracted with water, separated and purificated by ion exchange and silica gel G column chromatography.
Results: Thin layer chromatography (TLC) of the extracts and control cAMP showed the same Rf 0.
