“…On the other hand, toxic elements such as As, Cd, Hg and Pb pose health risks to humans at any concentration [ 12 ]. Anthropogenic activities often lead to pollution by toxic elements, which contaminate food through water, soil, and air [ 13 ]. To ensure food safety, regulations and safety measures have been implemented to monitor and limit the presence of toxic elements in food.…”

Sardinia, located in Italy, is a significant producer of Protected Designation of Origin (PDO) sheep cheeses. In response to the growing demand for high-quality, safe, and traceable food products, the elemental fingerprints of Pecorino Romano PDO and Pecorino Sardo PDO were determined on 200 samples of cheese using validated, inductively coupled plasma methods. The aim of this study was to collect data for food authentication studies, evaluate nutritional and safety aspects, and verify the influence of cheesemaking technology and seasonality on elemental fingerprints. According to European regulations, one 100 g serving of both cheeses provides over 30% of the recommended dietary allowance for calcium, sodium, zinc, selenium, and phosphorus, and over 15% of the recommended dietary intake for copper and magnesium. Toxic elements, such as Cd, As, Hg, and Pb, were frequently not quantified or measured at concentrations of toxicological interest. Linear discriminant analysis was used to discriminate between the two types of pecorino cheese with an accuracy of over 95%. The cheese-making process affects the elemental fingerprint, which can be used for authentication purposes. Seasonal variations in several elements have been observed and discussed.

“…Potentially Toxic Elements (PTE), which are present in high concentrations in sulfide-rich waste materials, are released in high amounts in acidic waters. Finally, as PTE generally increases their solubility with an increase in water acidity, AMD results in the release of highly acidic, PTE-rich, strongly pollutant waters, which can impact both ecosystems and humans [5][6][7][8].…”

Acid mine drainage (AMD) prevention or remediation is a major issue of the environmental management of sulfide-bearing active and abandoned mining sites, the main sources of acidic waters being wastes and tailings. The present work intends to check a circular economy approach to such issues in the mining region of Sardinia, where environmental pollution, due to AMD, is a major concern. Tests were conducted on basic drainage-producing feldspar mining wastes that could be recycled as buffering agents of sulfide-bearing tailings. Among the sulfide-bearing abandoned mining sites investigated, Furtei epithermal gold deposit tailings are the most polluting and those that can better test the buffering agent efficacy. Buffering test results show that buffering to near-neutral conditions can be attained following steps similar to those of pure calcite buffer. The buffering potential of the recycled waste is due to both the buffer calcite content, which provides short-term buffering, enhanced by feldspar content that can provide long-term buffering. Buffered waters show a dramatic decrease in the concentration of most of the metals present in the leachate, down to conditions that meet the requirements for the discharge of industrial waters according to Italian legislation.

The method employed for membrane preparation and nanoparticle incorporation in membrane systems can affect their properties. This work aims to compare the better strategy to obtain membranes from the preparation of PBAT [Poly(butylene adipate co‐terephthalate)] containing nanoclay Cloisite® 20A (C20A) (0, 0.5, and 1 wt.%) by combined Evaporation/Non‐solvent Induced Phase Separation (EIPS/NIPS) or dip coating methods. The SEM, TGA, contact angle measurements, FTIR, XRD, mechanical testing, and cost analysis characterized EIPS/NIPS to dip coating membranes. EIPS/NIPS membranes had smaller pores (0.3–0.5 μm), with a more homogeneous pore diameter distribution due to C20A nanoclay insertion. PBAT/0.5% C20AEIPS/NIPS was the more hydrophilic membrane (37°) with better mechanical properties proven by statistical analysis. The cost analysis showed that EIPS/NIPS membranes production cost per square meter (m2) was lower (US$ 73.4–73.8) than dip coating (US$ 89.0–99.2). The EIPS/NIPS method was the most economically and statistically advantageous, and its properties can favor future applications for PTEs removal in aqueous media.
