5.2 O oloa auina atu i fafo a Saina
Mai le 2015 i le 2019, o le aofaʻi o kamupani e 582 na faʻatau atu oloa faʻatekonolosi ma sauniuniga sili ona lelei, ma o le aofaʻi o oloa auina atu i fafo o kamupani e sefulu pito i luga na maua ai le 45% o le aofaʻi o le faʻaulufaleina (5-tausaga faʻaputuga).O kamupani pito i luga e sefulu o loʻo lisiina ile Laulau 2.
O le averesi o le auina atu i fafo o mea faʻapitoa e 2,400 tone / tausaga, ma o le maualuga o le faʻatau atu o oloa e 3,000 tone / tausaga.O le aofaʻi o oloa auina atu i fafo ua siitia mai lea tausaga i lea tausaga mai le 2015 i le 2019. O le averesi o le auina atu i fafo o sauniuniga faaletino e 14,800 tone/tausaga, ma le maualuga o le auina atu i fafo e 17,000 tone (2017), ona mautu ai lea o le aofaʻi o oloa auina atu i fafo;o le averesi o le tele o tapenaga e auina atu i fafo e 460 tone/tausaga, ma le maualuga e 515 tone/tausaga.
Mai le 2015 i le 2019, o oloa faʻapitoa ma sauniuniga o le cyhalothrin na faʻatau atu i maketi e 77.O maketi pito i luga e lima o le Iunaite Setete, Peleseuma, Initia, Atenitina, ma Pakisitana.O maketi e lima pito i luga na maua ai le 57% o le aofaʻi o oloa auina atu i fafo a Saina.(5 tausaga fa'aopoopo).
6 Tulaga fou o maketi
E tusa ai ma faʻamatalaga a le aufaasālalau, i le aso 7 o Me, 2022, i le taimi i le lotoifale, o se fale gaosi oloa a Initia agrochemical company Bharat Rasayan, lea e masani ona gaosia oloa pyrethroid ma isi mea faʻapitoa, na mu ina ua maeʻa le pa.
O Initia o se tasi o kamupani tele e leai ni pateni e gaosia ai vailaau faʻasaina i le lalolagi, o loʻo i ai le gafatia o le gaosiga o mea autu o mea tau pyrethroid, methyl betinate ma ether aldehyde, e maualuga tele.I le 2021, Bharat Rasayan o le a auina atu i fafo le aofaʻi o le sili atu i le 6,000 tone o vailaʻau faʻapitoa faʻamaʻi, sauniuniga ma mea faʻapitoa, lea e 61% o vailaʻau faʻapitoa, 13% sauniuniga ma 26% intermediates (tele pyrethroid intermediates).I le avea ai o se vaega taua mo le faʻapipiʻiina o vailaau faʻamaʻi pyrethroid, eter aldehyde o loʻo i ai le manaʻoga faʻaletausaga faaletausaga e tusa ma le 6,000 tone, lea e toeitiiti atoa le afa e manaʻomia ona faʻatau mai Initia.
Talu ai o le maketi i totonu o le atunuʻu mo cyhalothrin ua latalata i lona iuga, ma o le kamupani Initia e le o le atinaʻe autu lea e gaosia ai le alpha-cyhalothrin-related intermediates e pei ole ether aldehydes, o le aʻafiaga i luga o maketi i totonu o le atunuʻu e laʻititi lava, ma e manaʻomia tele le totogiina. gauai atu i le auina atu i fafo talu ai nei.Upusii.
