Te hangarau kimi me te whakahekenga o ngā poke trifluoromethyl pumau o te taiao
Nā te whānui o te whakamahinga o ngā matū trifluoromethyl (-cf ₃) i roto i te ahumahi me te oranga, kua nui haere te aro ki te raruraru o ngā parahanga trifluoromethyl pumau (pērā i ngā matū perfluorinated me polyfluoroalkyl, PFAS) i roto i te taiao. He pumau te taiao o ēnei parahanga, he kohikohinga koiora, ā, he paitini pea, ā, he tūraru ki te taiao rauropi me te hauora o te tangata. Nō reira, he mea tino nui te rangahau i ngā hangarau kimi me te whakahekenga whai hua.
Mō te hangarau kimi, kei te puta ake ngā tikanga tātari tairongo teitei. Ko te ine ira papatipu tandem chromatography wai (LC - MS/MS) kua noho hei huarahi matua mō te kimi i te PFAS i roto i te taiao me tōna taumira teitei me te tairongo teitei. Ka taea e tēnei tikanga te whakatau tika i te ihirangi me te hanganga o te PFAS iti i roto i ngā momo pāpāho taiao (pēnei i te wai, te oneone, ngā tauira koiora). Hei tāpiri, kua nui te ahunga whakamua o te hangarau kimi tere i runga i te kaupapa o te whakamātautau ārai mate. Mā te whakarite i ngā paturopi motuhake, ka tere te kimi i te PFAS i te wāhi, ka whakaratohia he taputapu watea mō te aroturuki taiao.
I roto i te mara o te hangarau whakahoro, ko te whakahoro matatau, te whakahoro whakaahua me te whakahoro koiora ngā huarahi rangahau matua. Ka taea e te tikanga whakahoro matatau te whakahoro i ngā poke mā te whakaputa i ngā rauropi kore waikura kaha (pērā i ngā rauropi kore hydroxyl) me te whakangaro i te waro. Pūhaumāota here o te PFAS. Ko te whakahoronga whakaahua-whakakorikori ka whakamahi i ngā takirua pū irahiko i hangaia e ngā Semiconductor Photocatalysts i raro i te mārama hei tīmata i te whakahoronga waikura o te PFAS. I ngā tau tata nei, kua whakaatuhia hoki te kaha o te hangarau whakahoronga koiora. Mā te tirotiro me te whakatipu i ngā momo moroiti ka taea te whakahoro i te PFAS, ka taea te huri i ngā poke hei matū kino mā te pākia o te moroiti. Mā te auahatanga tonu me te whakapai ake i te hangarau kimi me te whakahoro, ka whakaratohia he otinga whai hua hei whakaoti rapanga o ngā poke trifluoromethyl pumau i roto i te taiao.
