E’ stato firmato a Minamata, in Giappone, un accordo internazionale per la riduzione dell’uso del mercurio.
Secondo i termini dell’intesa, raggiunta sotto l’egida delle Nazioni Unite, a partire dal 2020 sarà vietato utilizzare il metallo pesante nella produzione di batterie, cosmetici, termometri e lampade a fluorescenza. La vendita di prodotti nuovi contenenti questo elemento chimico sarà pure vietata.
Verranno inoltre rafforzati i controlli sullo smaltimento e il deposito del mercurio, che oggi viene ancora impiegato per produrre catalizzatori, insetticidi e coloranti.
