Trace elements were quantified by ICP-OES.

The variation in the results may not be related to the bee species’ behaviors, but rather to their foraging territory to collect nectar/pollen and the type of plants and flowers visited. This observation allows considering honey as a good indicator for monitoring environmental contaminants.

This film exhibited distinct color changes from rose-red to purple-gray to yellow-green across a wide pH range (2–12). It responded rapidly to ammonia, with a visible color change occurring within 1 min. The incorporation of UiO-66 significantly improved color stability, maintaining an unnoticeable ΔE (<4) for up to 30 days. Furthermore, it enabled the film to be reused at least three times, addressing the common irreversibility problem in conventional anthocyanin-based systems. Testing with meat samples showed a linear relationship between the film’s color change and total volatile basic nitrogen (TVB-N) levels during spoilage, confirming its effectiveness as a freshness indicator. In addition, the film functioned as an active packaging material that effectively slowed the spoilage process.

The main raw materials for producing beer are: water, barley, hops, yeasts. Unlike other alcoholic or distilled beverages, water is added during the preparation of the must. Consequently, in the mineral content of beer, the composition of the water is of great importance. Among the trace elements, fluoride, can be a common ion in water. This study describes and validates a potentiometric method, using an ion-selective electrode, to measure fluoride concentrations in the beer samples without preliminary treatments. The obtained detection limit (LOD) is 0.0006 mg L<sup>−1</sup> while quantification limit (LOQ) is 0.0017 mg L<sup>−1</sup>. The standard addition method, used in this research, allows to obtain straight lines whose r<sup>2</sup> is higher 0.999.
