TPCH a cikin Amurka yana fitar da jagororin PFAS da Phthalates

A cikin Nuwamba 2023, tsarin US TPCH ya ba da takaddar jagora akan PFAS da Phthalates a cikin marufi. Wannan takaddar jagora tana ba da shawarwari kan hanyoyin gwaji don sinadarai waɗanda ke bin marufi masu guba.

A cikin 2021, ƙa'idodi za su haɗa da PFAS da Phthalates a ƙarƙashin sarrafawa kuma sun hana amfani da niyya a cikin marufi da sarkar samar da sa. A halin yanzu, kowace jiha ta yi gyare-gyare ga dokokin data kasance ko kuma kafa sabbin dokoki da ka'idoji don hana abubuwa masu guba da cutarwa a cikin marufi. Kwanan nan, jihohi da yawa sun hana amfani da abubuwan PFAS a cikin marufi na abinci.
Wannan takaddar jagora tana ba da shawarar hanyoyin gwaji don PFAS, kamar jimlar fluoride. Idan jimlar abun ciki na fluorine yana ƙasa da 100ppm kuma ya dace da ƙa'idodin sarrafa inganci, ana iya ɗaukar samfurin da alama ba da gangan ƙara abubuwan PFAS ba. Idan jimlar abun ciki na fluorine yayi ƙasa sosai (kamar ƙasa da 100ppm), ana iya ƙara tabbatarwa tare da mai siyarwa. Takardar jagororin ta jaddada cewa nuna gaskiya yana da mahimmanci don bin ka'ida, kuma ana ba da shawarar yin amfani da shirin mai zuwa don tabbatar da ko PFAS na son ƙarawa:
1) Tambayi masu kaya don cikakkun bayanai;
Bukatar masu samar da kayayyaki don samar da cikakkun bayanan bayanai;
2) Nemi masu siyarwa don rufe idan an ƙara sinadarai na PFAS;
Ana buƙatar masu siyarwa don bayyana ko an ƙara abubuwan PFAS;
3) Nemo takaddun shaida na ɓangare na uku na kayan ku
Neman takaddun shaida na ɓangare na uku.
TPCH yana ba da shawarar yin amfani da hanyar SW 846 8270 don shirye-shiryen samfurin da hanyar EPA 3541 don gwajin kayan tattarawa game da hanyar gwaji don Phthalates. Mai zuwa shine jerin phthalates da aka fi bincika ta hanyoyin gwaji na sama:
