Lo que todavía no está claro es qué tan extendidos están estos metales en los envases reales del mercado argentino.","quienFirma":"Revista International Journal of Environment and Pollution","confianza":"revisado","consulta":null},"sello":{"hash":"3016a12fb387b8f86e63326e872b33799bea43a87118c18257a7b50431904e45","sello":"345871ae39779b07b80a33a6755acf0aa2a50b7dc3288f671a931549702c1e37","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6576209,"aleatorio":"9074ace8c0ae20057eb880829050613cb73cd60fded83f48bb2f306d0d4a2494","tiempo":"2026-10-23T01:01:30.000Z"},"nist":{"cadena":2,"pulso":1995304,"salida":"C132E79D1D1B18CC48979652339A4542B09FFE47EF7A0958DC73CF436D0AA11F4B2F0B0861D0CC321392193D11AFEF3BE095877299420A86C225166F1E461C98","tiempo":"2026-10-23T01:01:00.000Z"},"noAntes":"2026-10-23T01:01:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 23 01:02:06 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"New test measures potentially harmful metals in cellulose food packaging","descripcion":"A technique for detecting potentially harmful metals in regenerated cellulose food packaging is discussed in the International Journal of Environment and Pollution.
