He paura tioata mā te EDTA. Anei te whakaahuatanga taipitopito o te āhua o te EDTA:

Āhua: Paura tioata mā, kāore he kakara, kāore he reka.
‌Wairewa‌: Kāore e wairewa i roto i te waipiro me ngā whakarewa rauropi whānui, engari ka wairewa i roto i te wai matao (tere puhoi), te wai wera, te hauwai konutai, te konutai kāponāte me ngā otinga haukini. Ka wairewa tōna tote konganuku kawakore i roto i te wai, ā, ko te wairewa i roto i te wai he 0.5g/L (25℃).
‌Ira rewa‌: Ko te ira rewa he 240℃ (pirau), ā, e whakapono ana ētahi he 250℃ te ira rewa (pirau).
Hei whakarāpopototanga, ka puta te EDTA hei paura tioata ma i te pāmahana me te pēhanga rūma, ā, he āhuatanga ā-tinana, ā-matū hoki ōna.

He whānuitia ngā whakamahinga o te waikawa Ethylenediaminetetraacetic (EDTA), tae atu ki:

‌Kaiwhakakorikori ion konganuku‌: Ka taea e ia te hanga matatini pumau me ngā momo ion konganuku, ā, e whakamahia ana i roto i ngā tātari matū me ngā taiwhanga hei whakakore i te pokanoa o ngā ion konganuku ki te tātari.
‌Ahumahi kai‌: Hei tāpiri kai, ka whakau i ētahi kai o te kai, ā, ka ārai i te pirau me te tae rerekē o te kai i puta mai i ngā katote konganuku.
‌Marautanga hauora‌: E whakamahia ana hei rongoā i te paihana konganuku, pērā i te paihana mata, ā, e whakamahia ana te whakaora chelation hei tango i ngā katote konganuku paitini mai i te tinana.
‌Whakapaipai‌: Whakaū i ngā kai o roto i ngā tātai whakapaipai.
Hopi horoi: Tangohia te konupūmā, te konupora me ētahi atu katote i te wai mārō hei whakapai ake i te pānga horoi.
Te tā me te tae i roto i ngā kakahu: Whakapai ake i te kounga o te tae.
Ahuwhenua: Whakamahia hei whakapai ake i te oneone me te whakamahi tongi.
‌Ētahi atu‌: Ka taea hoki te whakamahi hei whakau i roto i te maimoatanga wai me ngā tauhohenga PCR, me ētahi atu.
