Tre quarti del miele prodotto nel mondo contiene neonicotinoidi, un tipo di pesticida. La scoperta, pubblicata su “Science”, è di un team di ricercatori svizzeri dell’Università di Neuchâtel, i quali hanno esaminato 198 campioni di miele proveniente da tutto il mondo tra il 2015 e il 2016.
Le concentrazioni riscontrate sono al di sotto del valore soglia ammesso dall’Unione Europea per il consumo umano, ma si tratta di una contaminazione pericolosa per tutti gli impollinatori, e non si escludono conseguenze a lungo termine sul uomo.
I campioni di prodotto più inquinati sono risultati quelli provenienti da Nordamerica (86%), Asia (79%), ed Europa (79%), mentre le concentrazioni meno elevate si sono riscontrate in Sudamerica (57%).
Questo genere di insetticida è un derivato della nicotina, e viene spruzzato sulle foglie o messo nel sotto suolo in forma di granuli per eliminare gli insetti indesiderati.
