Reliable and sensitive analytical platform to assess dietary exposure of pigs to mycotoxins and explore potential urinary biomarkers.

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.

Static headspace-gas chromatography with mass spectrometry for the assessment of the bioaccumulation of volatile organic compounds associated with microplastics in animal tissues.

Background: The excessive increase in the production of plastics worldwide and their mismanagement have turned these materials into a threat to the environment and living organisms. Plastics undergo erosion and degradation processes releasing additives, monomers of their formulation, and even generating one of the most worrying emerging pollutants: microplastics. These contaminants have been found in both aquatic and terrestrial ecosystems, so it is clear the need to develop a methodology to determine the accumulation of these pollutants and their associated compounds in living organisms.

Evaluation of the potential use of protoporphyrins as biomarkers of anemic disease in human urine from inflammatory bowel disease patients.

Protoporphyrins are organic compounds with cyclic structure that are synthesised by a wide variety of organisms. In humans, these compounds are detected in blood and urine, with significantly higher levels in blood. Their potential as biomarkers of anemia and other diseases is currently being investigated, as their levels change according to the biochemical processes associated with the disease.

Analytical strategy to assess the microbial degradation of poly(butylene-adipate-co-terephthalate)/poly(lactic acid) films.

Plastic is widely used in agricultural applications, but its waste has an adverse environmental impact and a long-term detrimental effect. The development of biodegradable plastics for agricultural use is increasing to mitigate plastic waste. The most commonly used biodegradable plastic is poly(butylene adipate co-terephthalate)/poly(lactic acid) (PBAT/PLA) polymer.
