Edible ice is often produced by special machines that can represent a source of significant chemical and microbiological contamination. In this work, the presence phthalic acid esters (phthalates, PAEs) heavy metals in cubes distributed 77 vending installed two different zones southern Italy fed water from public supply was investigated. Solid-phase microextraction coupled to gas chromatography−mass spectrometry (SPME-GC/MS) used evaluate contamination with four PAEs, which were selected because they are commonly production food-contact plastics, while inductively plasma mass (ICP/MS) quantify metals. It found samples, especially those one considered (zone 2), exceeded dibutyl phthalate (DBP) threshold limit value; some other zone 1) instead showed levels both lead (Pb) nickel (Ni) up order magnitude higher than observed samples collected 2 maximum permitted values (European Directive n. 2184/2020). Since connected be free all target compounds metals, high DBP, Ni, Pb could attributed components and/or state repair themselves.
