Isibulali-zinambuzane siphakathi

Isibulali-zinambuzane sisixhobo esibalulekileyo semveliso kwimveliso yezolimo, edlala indima ebaluleke kakhulu ekulawuleni izifo, izitshabalalisi kunye nokhula, ukuzinzisa nokuphucula isivuno sezityalo.

Nangona ichatshazelwa lixabiso lemveliso yezolimo, indawo yokutyala, imozulu, uluhlu lwempahla kunye nezinye izinto, ukuthengiswa kwezitshabalalisi kuya kubonisa ukuguquguquka okuthile komjikelo unyaka nonyaka, kodwa imfuno isenokuqina.

Ngokwedatha evela kwi-Bureau yeSizwe ye-Statistics, ukuveliswa kwezitshabalalisi zemichiza kwilizwe lonke kubonise indlela ehlayo ukusukela ngo-2017.
Kwi-2017, imveliso ye-pesticides yawela kwi-2.941 yezigidi zeetoni, kodwa ngo-2018 yawela kwi-2.083 yezigidi zeetoni. Ngo-2019, iziphumo zezibulali-zinambuzane zemichiza zayeka ukuwa kwaye zenyuka zaya kutsho kwi-2.2539 yezigidi zeetoni, zenyuka nge-1.4 yeepesenti ngonyaka.

Kwiminyaka yakutshanje, ingeniso yokuthengisa izibulali-zinambuzane eTshayina iyonke igcine umkhwa owandayo.
Ngo-2018, ngenxa yophuhliso lwezitshabalalisi zebhayoloji kunye nokunyuka kwamaxabiso emveliso, kunye nokwandiswa kwemfuno yezitshabalalisi kwizityalo zemali ezifana nomqhaphu kunye neziseko zophuhliso, ingeniso yokuthengisa ishishini yayimalunga ne-329 yeebhiliyoni zeeyuan.
Kuqikelelwa ukuba ubungakanani bemarike obunokubakho bolimo lwaseTshayina kulindeleke ukuba bunyuke ngo-2020.

Izitshabalalisi ezahlukeneyo zifuna imidibaniso eyahlukeneyo kwinkqubo yemveliso.
Imveliso eveliswa ngokulungiswa kwemveliso yezolimo ikwayindlela ephakathi edibanisa izinto ezimbini okanye ngaphezulu kunye.
Kwizitshabalalisi zinokuqondwa njenge-synergist, eyaziwa ngokuba yi-organic intermediates.
Ekuqaleni ibhekisa kusetyenziso lwetha yamalahle okanye iimveliso zepetroleum njengezinto ezisetyenziswayo zokwenziwa kweziqholo, idayi, iresin, iziyobisi, iiplasticizers, irabha accelerator kunye nezinye iimveliso zeekhemikhali, eziveliswe kwinkqubo yeemveliso eziphakathi.

Ukudityaniswa kwe-intermediates ngokubanzi kuqhutyelwa kwi-reactor, kwaye i-intermediates eyenziwe yahlulwa kwaye ihlanjululwe, ngokuqhelekileyo ngeteknoloji yokukhupha.
Izibulala-zinambuzane kunye nokutsalwa kwekloroform kushishino lweekhemikhali kushishino lweyunithi eqhelekileyo, inkqubo yokusebenza yemveli ithatha ikholamu yedistillation, olu hlobo lwenkqubo yokusebenza luntsonkothile, luphantsi ukusebenza kakuhle, ukusetyenziswa kwamandla kukhulu, ngoko ke ngokunzulu kolwahlulo lwentlalo yabasebenzi kunye Inkqubela phambili yetekhnoloji yemveliso, uninzi lwamashishini aqala ukuphuculwa kwetekhnoloji, kwaye akhethe inkqubo esebenzayo ngakumbi.
