Metabolomic profiling of Fiore Sardo cheese: Investigation of the influence of thermal treatment and ripening time using univariate and multivariate classification techniques.
Food Chem
October 2024
Dipartimento di Ingegneria Meccanica, Chimica e dei Materiali, Università degli Studi di Cagliari, Via Marengo 2, Cagliari 09123, Italy.
Article Synopsis
- The study examined how different heat treatments (thermization at 57°C and 68°C) and ripening times (105 and 180 days) affect cheese metabolite profiles by analyzing 95 cheese samples using GC-MS.
- Statistical methods, including ANOVA and PLS-DA, were used to identify significant changes in compound levels due to the treatments, achieving around 76% accuracy in classification.
- Key findings showed that amino acids and an endocannabinoid were mainly influenced by ripening time, while biogenic amines and saccharides were significantly impacted by the heat treatment process.
Greenhouse investigation on the phytoremediation potential of pioneer tree Mill. in abandoned mine site.

Tailings and mine dumps are often pollutant sources that pose serious environmental threats to surrounding areas. The use of pioneer vascular plants to extract or stabilize metals is considered among the more effective mine tailing reclamation techniques. The study aimed at evaluating the phytoremediation potential of in abandoned mine-tailing (SW-Sardinia, Italy).

July 2023
Dipartimento di Scienze della vita e Ambiente, Cittadella Universitaria di Monserrato Blocco A, 09012 Monserrato, Italy.
Article Synopsis
- The study analyzed Pecorino Romano cheese for seasonal differences in fatty acids and minerals by examining samples from January, April, and June, noting some samples had missing data.
- Probabilistic principal component analysis and Linear Discriminant Analysis were used to effectively classify the samples by production season, even with incomplete data.
- Key findings showed higher levels of beneficial fatty acids in spring, while the accuracy of the classification model reached 98%, and the imputation of missing data achieved an impressive 99.53% accuracy.
in Contaminated Mining Sites: Study of the Transfer of Metals in the Plant-Soil System Using the BCR Procedure.
Toxics
November 2022
Department of Chemical and Geological Sciences, University of Cagliari, Cittadella Universitaria di Monserrato-Blocco A, 09042 Monserrato CA, Italy.
The study aimed at evaluating the geochemical fractions of Zn, Pb, Cd and their bioavailability in soil in-depth and around the root of grown on heavily contaminated mine tailing in south-western Sardinia, Italy. The contaminated substrates were partly investigated in a previous study and are composed of pyrite, dolomite, calcite, quartz, gypsum, barite, iron-sulfate and iron-oxide. The geochemical fractions and bioavailability of Zn, Pb and Cd were measured through the BCR extractions method.

Dipartimento di Scienze della Terra, Università di Firenze, Via G. La Pira 4, 50121, Florence, Italy.
Thermal waters near the city of Viterbo (Central Italy) are known to show high As contents (up to 600 µg/l). Travertine is precipitated by these waters, forming extended plateau. In this study, we determine the As content, speciation and bioaccessibility in soil and travertine samples collected near a recreational area highly frequented by local inhabitants and tourists to investigate the risk of As exposure through accidental ingestion of soil particles.

December 2020
Department of Life and Environmental Science, Università Politecnica delle Marche, via Brecce Bianche, 60122, Ancona, Italy. Electronic address:
Cigarette butts are the most common form of litter in the world and their environmental impact is related to both persistence and potential toxic effects for chemical composition. The objective of this study was to assess the acute toxicity (LC-48 h) of human-smoked cigarette butts leachate on 3 cultured genera of benthic foraminifera: the calcareous perforate Rosalina globularis, the calcareous imperforate Quinqueloculina spp., and the agglutinated Textularia agglutinans.
