I tēnei wā, he maha ngā taiwhanga kua rite ki ngā taputapu kimi matatau ake, pērā i: LC-MS, GC-MS, ICP-MS, me ētahi atu. He tino teitei te tika o ēnei taputapu kimi, ka taea te eke ki te taumata PPM, PPB rānei. I taua wā anō, kua tino pai ake te whai huatanga o te kimi. He maha ake ngā taputapu tino tika e hiahiatia ana e ngā kaimahi taiwhanga hei whakahaere, ā, ko te uaua me te taumaha o te maimoatanga tauira i mua i te whakamahinga ka moumou i te nui o te wā whai hua o ngā kaimahi taiwhanga.
Heoi, he moumou taima noa iho te horoi ā-ringa i ēnei taputapu whakamātautau, ā, ka whakawhāiti i te whakapainga o te whai huatanga katoa o te whakamātautau. Kei te pā tika ngā kaiwhakamātautau ki ngā momo matū horoi, pērā i te waikawa kaha, te kawakore kaha, te waikawa chromic, me ētahi atu. Tērā pea ka whara, ka whara tinana hoki te hauora o te kaiwhakamātautau. Ina koa ko te kino o te chromium Hexavalent ki te tinana e kore e taea te whakakore. Kāore anō kia tutuki i te horoi ā-ringa ngā whakaritenga paerewa taiwhanga hou pērā i te paerewa, te tuhi raraunga me te whai i ngā raraunga.
Nā ēnei me ētahi atu ngoikoretanga i akiaki mātou ki te whakawhanake i ngā taputapu pēnei i temīhini horoi pounamu taiwhangaMai i ngā wheako whakamahi, ka taea e ia te whakaoti rapanga i runga ake nei me te tino pai, ā, ka tino whai pānga pai ki te whakapainga whānui o te taiwhanga.Kaihoroi karāhe taiwhangaKo te nuinga o te pūnaha he pūnaha horoi, he pūnaha horoi, he pūnaha horoi wai me te ara iahiko whakahaere. Ka taea te hono atu ki ngā momo puna wai e toru, te matao, te wera me te tango-ion, hei horoi me te patu huakita i ngā taputapu taiwhanga. He mea hanga te hanganga whānui ki te kowiri tira, ko te anga o waho he kowiri tira 304, ā, ko te kāpata o roto he kowiri tira 316, he pai te ātete ki te waikura; he ngāwari, he whakamarie hoki te whakamahi i te pātene o mua, ā, he penapena hiko, ā, he ataahua, he ātaahua hoki te āhua o te kowiri tira ngāwari.
He mahi horoi aunoa tā te taputapu, he tino watea mō te horoi me te patu huakita, ā, ka taea te pupuri i te mīhini me ngā taonga horoi kia ma, kia akuaku hoki. He pai mō ngā taputapu taiwhanga pēnei i te baster, te ngongo whakamātautau, te rango ine, te pounamu kōniko, te pipette, me ētahi atu. Ā, ka taea te whakauru ki ngā whata horoi e hiahiatia ana e ai ki ngā hiahia o te kiritaki. Ka taea te horoi rehu; mā te tatau haumaru tōia-mua ka pai ake te whakahaere. Ko te pūwero hurihuri momo kaukau i te taha o runga o te kāpata kua hangaia kia kore he pito mate, ka taea te horoi ōrite i ngā momo taputapu katoa. Kei ia huinga whata patu huakita ngā pou rehu wai (16—32 ngā wahi ka taea te whakanoho) kia taea ai te rehu tika te wai horoi ki roto i te ipu hei horoi.
Hei whakarāpopototanga, ko te ia o te ao whānui ko te piki haere o ngā taiwhanga e whiriwhiri ana ki te whakamahi i ngā mīhini horoi pounamu taiwhanga, e kore e taea anake te penapena i te wā me te utu, engari ka pai ake hoki te whakamana i ngā hua o ngā whakamātautau. Koinei te mea pai rawa atu o ngā ao e rua.
