L'Associazione dei chimici cantonali svizzeri ha controllato un centinaio di oggetti per il barbecue per verificare se rilasciassero metallo: un quarto di questi è risultato di cattiva qualità. In caso di utilizzo frequente i metalli liberati da questi prodotti possono infatti nuocere alla salute, si legge in un comunicato odierno.
Sono stati analizzati complessivamente 99 oggetti utilizzati per fare barbecue come spiedini (45), griglie (19), girarrosti per pesce, carne e verdure (17), teglie da griglia (11) e utensili per griglia (7). Secondo la legislazione questi oggetti possono liberare metalli solo in quantità innocue per la salute e tecnicamente inevitabili, ricorda l'Associazione dei chimici cantonali.
Sul totale di 99 prodotti esaminati 24, ossia un quarto, sono risultati di cattiva qualità per l'elevata liberazione di uno o più metalli. Risultati particolarmente negativi sono stati evidenziati nei girarrosti per pesce, carne e verdura, con oltre la metà di non conformità. I metalli maggiormente liberati erano il nichel e il manganese.
L'Associazione dei chimici cantonali non rivela nel dettaglio di quali prodotti si tratti. "Non possiamo fornire queste informazioni", ha detto oggi Nicola Forrer, Chimico cantonale aggiunto del Ticino. "Il nostro lavoro è protetto dal segreto d'ufficio", ha precisato.
