Pēhea te hangarau nano-a-wai e whakapiki ai i te whaihua o te whakamahi pesticide?

Te hangarau nano e whakamahi ana i te wai: Te whai muri i te whakamahi tika o ngā patu aruaru

I roto i te ao hangarau ahuwhenua, ko te pātai matua mō te whakaiti i te whakamahinga o ngā patu aruaru ēnei matū kore e pēhi i te āhei o te tiaki i ngā tipu, he wero nui tonu mō te tiaki tipu toitū. I ngā tau tata nei, kua neke haere te whakamahinga o te hangarau nano i roto i te ahuwhenua mai i te ariā ki te mahi, otirā ko ngā pūnaha kawe nano e whakamahi ana i te wai hei wāhi, nā te āhua pai ki te taiao me te kaha ki te tuku ki te wāhi e hiahiatia ana, e noho ana hei mema nui i roto i te kete utauta o te ahuwhenua tōtika.

Te mātāpono hangarau me ngā painga

• Ko te whakaaro matua o te kawe nano i runga i te wai, ko te kōpaki i ngā wāhanga whakahaere o te patu aruaru ki roto i ngā pūrere o te rahi nano (pērā i te liposome, te micelle polymer, te pūngao nano silica rānei), ā, ka whakakotahi ki te pūnaha whakatārewatanga i runga i te wai. Ina whakatauritea ki ngā hinu kakano tawhito, ki ngā paura mākū rānei, ko te patu aruaru kua hangaia ki te nano e whai ana i ēnei āhuatanga matua:
• Te nui o te horahanga mata kua whakapikihia: Ka piki ake te ōritenga me te kapi o te patu aruaru ki runga i te mata o ngā tipu.
• Te kaha ki te tuku haere e whakahaerea ana: Mā te pirau o ngā rauemi kawe, te urupare ki te taiao (pH, pāmahana) rānei, ka puta haere ngā wāhanga whaihua, ka roa te wā whaihua.
• Te ātete ki te horoinga ua: Ka tūhono kaha ake ngā pūrere nano ki te papahanga wāwaru o ngā rau, ka iti te ngaronga i te ua.
• Te tuku ki te wāhi e hiahiatia ana: Mā te whakapaipai i te mata, ka taea te whakamōhio motuhake ki ngā pepeke me ngā mate, ka iti te pānga ki ngā mea ehara i te whāinga.

Ko ēnei āhuatanga e tohu ana ka taea e ngā kaimahi te whakaiti i te nui o te patu e whakamahia ana i ia eka, i te wā e whiwhi ana i te āhua o te whakahaere, i te pai ake rānei i ngā āhua tawhito. Hei tauira, ko ngā whakamātautau i te mara mō ngā patu taru i roto i te māra raihi, mō ngā patu haurangi mō te tīwhiri rānei, e whakaatu ana ko te whakamahinga o ngā wāhanga whaihua ka heke iho ki te 30% ki te 50%, engari kei te 90% te pai o te whakahaere.

Ngā pānga ki te ahumahi: Te piriti mai i te whare taiwhanga ki te mara

Ahakoa kua whakaatu te patu aruaru nano i runga i te wai i ngā painga nui i roto i te whare taiwhanga, kei te anga tonu ki ngā ārai o te pūtea me te whakapūmau i te whakaputanga nui. I tēnei wā, he maha ngā kamupene hou me ngā whare rangahau e arotahi ana ki tēnei rohe, ā, kei mua a Haina, Inia me te Hononga o Amerika i te taha o te whakawhanaketanga hangarau.

• Mai i te tirohanga o te mekameka utauta ahuwhenua, ka whai pānga te hangarau nano ki ngā kaihanga patu aruaru, ki ngā kaihoko me ngā kaimahi:
• Ngā kamupene patu aruaru: Me whakatika i ngā tukanga whakauru, ka whakangao ki ngā rārangi whakaputa nano, ā, ka mahi tahi me ngā kamupene pūtaiao rauemi.
• Ngā kaimahi: Ka whiwhi painga mai i te iti ake o ngā rehu me te iti ake o te utu mō te patu, me te whakaiti i te tūpono pāitini ki ngā kaimahi.
• Te whakahaere me te tiaki taiao: Mā te tuku tika ake, ka taea te whakaiti i te noho o ngā patu aruaru i roto i te oneone me te wai, e āwhina ana ki te whakatutuki i ngā whāinga ESG o te ahuwhenua.

Te titiro ki mua### Tirohanga ki mua

I roto i te 3-5 tau e heke mai nei, ko ngā pesticide nanomai-i-wai ka puta mai i te wāhanga whakamana ki te whakatairanga pakihi iti. Ko ngā āhuatanga matua e akiaki ana: 1. Te hekenga o te utu o ngā rawa kawe nano: Ko ngā rawa kawe hou pēnei i te polymers whakaheke me te silica māori ka whakaheke i te utu o ngā whakahaerenga. 2. Ngā pūnaha whakamākūtanga me te whakamahi paihana ā-matihiko: Ka taea e ngā whakahaerenga nano te mahi tahi me ngā drone me ngā rehu āta whakaaro ki te whakamahi taurangi, kia pai ake te whaihua. 3. Te tautoko ā-ture: Ko ngā kaupapa here whakaheke pesticide a ngā whenua me ngā pūtea āwhina māra kākāriki ka tere ake te rēhita me te whakamahi o ngā pesticide nano.

He tika, me roa tonu te rangahau mō te āhua o ngā matūriki nano ki te taiao me te tūraru o te kai, engari ko ngā aromatawai paitini tuatahi e tohu ana he pai ake te haumaru o ngā kawe wai ki te wai i ngā pūnaha whakarewa waro tawhito.

Hei whakarāpopoto, e whakarato ana te hangarau wai-nano i tētahi ara e taea ai te "whakaheke te nui me te whakapiki te whaihua" mō te whakamahi pesticide, ā, ko te whakakotahitanga ki te ahuwhenua tika me te pāmu matihiko ka waiho hei aronga nui mō te tiaki tipu tauwhiro ā muri ake. Me aro tonu te hapori hangarau ahuwhenua ki ngā raraunga whakamātau me ngā ahunga whakamua o te umanga i tēnei wāhanga, kia tino mōhio ai ki tōna uara i roto i te mahi ahuwhenua nui.
