A reliable and sensitive analytical platform is proposed for the assessment of pig exposure to mycotoxins through the consumption of commercial feed. A total of 48 naturally contaminated feed and 55 urine samples collected from eight Spanish farms were analyzed using a fast and simple methodology based on solid-liquid extraction (SLE) or liquid-liquid extraction (LLE) and dispersive liquid-liquid microextraction (DLLME). High-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS) was used for the targeted analysis of 27 mycotoxins from different families in both matrices achieving limits of quantification in a range of 0.

Therefore, it is necessary to apply effective techniques to remove these pollutants from soil. This work was aimed to study the effectiveness of two advance oxidation processes (photocatalysis and ozonation) in the degradation of carbamazepine (CBZ) residues in three different soil matrices.

- * In a study of nestling eagle owls, ARs were found in 91.5% of blood samples, with many individuals showing multiple AR compounds, primarily second-generation ARs (SGARs).
- * While the overall health of the sampled owls appeared good, there was a positive but not significant correlation between AR levels and prothrombin time; higher AR concentrations were linked to urban areas and landfills, indicating a need for better monitoring of these pollutants.
Reusing reclaimed water for crop irrigation can mitigate water scarcity in agriculture; however, contaminants such as pharmaceuticals and pesticides in wastewater pose risks. This study investigated the impact of a coupled bio-solar photocatalytic treatment on the reclamation of water polluted with seven pharmaceuticals and seven pesticides for irrigation of two tomato crop cycles. Pollutant residues were removed using natural sunlight and TiO/NaSO in a pilot plant located in Murcia, Spain.

- Neonicotinoids are a type of insecticide that can harm farmland birds, but there's not much known about their effects on waterbirds.
- In a study in Finland, scientists looked for seven types of neonicotinoids in the blood of female common goldeneyes but couldn’t find any.
- The results suggest that these bird habitats are currently safe from neonicotinoid exposure, but more research is needed to understand the impact on the food chain and other birds.
