Institute of Meteorology and Water Management, National Research Institute, Waszyngtona 42, 81-342 Gdynia, Poland.
In this study, the results of a comprehensive assessment of the variability in the occurrence of ten perfluorinated compounds (PFAS) in fish tissues originating from 2014 to 2019 from six fisheries in the Baltic Sea are presented. A total of 360 fish samples of three species (perch, herring and flatfish) were analysed. For the determination of PFAS, both linear and branched stereoisomers, LC-ESI-MS/MS technique preceded by simultaneous SPE isolation was validated and applied.

Background: We sought to explore the molecular mechanisms underpinning acute lung injury (ALI) caused by poisoning with paraquat (PQ).
Methods: Selection mice were intraperitoneally injected with PQ at 40 mg/kg, whereas controls were injected with sterile saline. On days 2, 7, and 14 after administration, mice were anesthetized and sacrificed, and lung tissue was removed.

Freshwater environments are biodiversity hotspots under multiple pressures, including pesticide exposure. S-metolachlor, a widely used herbicide, can induce genotoxic, cytotoxic and physiological effects in captive fish, but we have a limited understanding of the effects of exposure to S-metolachlor in free-living vertebrates. We carried out an original field experiment using integrative approaches across biological levels and temporal scales.

Shifts in host-associated microbiomes can impact both host and microbes. It is of interest to understand how perturbations, like the introduction of exogenous chemicals, impact microbiomes. In poison frogs (family Dendrobatidae), the skin microbiome is exposed to alkaloids that the frogs sequester for defense.

Article Synopsis
- Mycotoxins, which are harmful fungal toxins, can negatively affect pregnant women and their babies, but there's limited information about their exposure in the US, particularly among pregnant women.
- This study analyzed mycotoxin exposure in a group of 50 women during pregnancy by testing samples of their serum and urine at various stages using advanced liquid chromatography techniques.
- Results indicated the presence of several mycotoxins, with notable detection rates for ochratoxin A and deoxynivalenol, showing some women exceeded recommended daily intake levels for these toxins.
