Mankhwala ophera tizilombo ndi mankhwala omwe amagwiritsidwa ntchito kupha tizirombo, makoswe, mafangasi ndi zomera zowononga (namsongole).Kuphatikiza apo, amagwiritsidwanso ntchito paumoyo wa anthu kupha zotengera matenda monga udzudzu.Chifukwa angayambitse poizoni kwa zamoyo zina, kuphatikizapo anthu, mankhwala ophera tizilombo ayenera kugwiritsidwa ntchito mosamala ndi kusamalidwa bwino1.
Kuntchito, kukhudzana ndi mankhwala ophera tizilombo kunyumba kapena m'munda kungayambitse kukhudzana ndi mankhwala ophera tizilombo, mwachitsanzo kudzera m'zakudya zomwe zili ndi kachilombo.Bungwe la WHO likuwunikanso umboniwo ndikukhazikitsa malire ovomerezeka padziko lonse lapansi kuti ateteze anthu ku zoopsa zomwe zingachitike chifukwa cha mankhwala ophera tizilombo.2
Reversed-phase high performance liquid chromatography (HPLC) imagwiritsidwa ntchito nthawi zambiri kuyerekeza kuchuluka kwa zinthu zomwe zimagwira ntchito mu mankhwala ophera tizilombo.Komabe, mtundu uwu wa chromatography umafuna kugwiritsa ntchito zosungunulira zapoizoni, ndipo ndi nthawi yambiri komanso ophunzitsidwa bwino, zomwe zimapangitsa kuti pakhale ndalama zambiri zowunikira nthawi zonse.Kugwiritsa ntchito zowoneka pafupi ndi ma infrared spectroscopy (Vis-NIRS) m'malo mwa HPLC kumatha kusunga nthawi ndi ndalama.
Pofuna kuyesa mphamvu yogwiritsira ntchito Vis-NIRS m'malo mwa HPLC, zitsanzo 24-37 za mankhwala ophera tizilombo omwe amadziwika kuti ndi othandiza kwambiri adakonzedwa: abamectin EC, amimectin EC, cyfluthrin EC, cypermethrin, ndi glyphosate.Unikani kugwirizana pakati pa zosintha.Deta ya Spectral ndi makonda.
NIRS RapidLiquid analyzer imagwiritsidwa ntchito kupeza mawonekedwe amtundu wake wonse (400-2500 nm).Chitsanzocho chimayikidwa mu botolo lagalasi lotayidwa ndi mainchesi 4 mm.Pulogalamu ya Vision Air 2.0 Complete imagwiritsidwa ntchito posonkhanitsa ndi kuyang'anira deta komanso kupanga njira zochulukira.Kuwongolera pang'ono kwa ma squares (PLS) kunachitika pachitsanzo chilichonse chowunikidwa, ndipo kutsimikizira kwamkati (kusiyani chimodzi) kudagwiritsidwa ntchito kutsimikizira magwiridwe antchito amtundu womwe udatengedwa panthawi yopanga njira.
Chithunzi 1. NIRS XDS RapidLiquid analyzer imagwiritsidwa ntchito pakupeza deta ya spectral pamtundu wonse wa 400 nm mpaka 2500 nm.
Pofuna kuwerengera chigawo chilichonse mu mankhwala ophera tizilombo, chitsanzo chogwiritsa ntchito zinthu ziwiri chinakhazikitsidwa, ndi zolakwika zamtundu wa calibration (SEC) za 0.05% ndi zolakwika zovomerezeka (SECV) za 0.06%.Pagawo lililonse logwira ntchito, ma R2 pakati pa mtengo womwe waperekedwa ndi mtengo wowerengedwa ndi 0.9946, 0.9911, 0.9912, 0.0052, ndi 0.9952, motsatana.
Chithunzi 2: Zowonera zamitundu 18 za mankhwala ophera tizilombo okhala ndi abamectin pakati pa 1.8% ndi 3.8%.
Chithunzi 3. Grafu yolumikizana pakati pa zinthu za abamectin zomwe zidanenedweratu ndi Vis-NIRS ndi mtengo wamawu woyesedwa ndi HPLC.
Chithunzi 4: Zowonetsa zamitundu 35 za mankhwala ophera tizilombo, momwe kuchuluka kwa amomycin ndi 1.5-3.5%.
Chithunzi 5. Grafu yolumikizana pakati pa zomwe amimectin adanenedweratu ndi Vis-NIRS ndi mtengo wamawu woyesedwa ndi HPLC.
Chithunzi 6. Mawonekedwe opangira ma data 24 a mankhwala ophera tizilombo okhala ndi cyfluthrin kuchuluka kwa 2.3-4.2%.
Chithunzi 7. Grafu yolumikizana pakati pa zinthu za cyfluthrin zonenedweratu ndi Vis-NIRS ndi mtengo wamawu woyesedwa ndi HPLC.
Chithunzi 8. The yaiwisi deta sipekitiramu wa 27 mankhwala zitsanzo ndi cypermethrin ndende ya 4.0-5.8%.
Chithunzi 9. Grafu yolumikizana pakati pa zinthu za cypermethrin zomwe zinanenedweratu ndi Vis-NIRS ndi mtengo waumboni womwe umayesedwa ndi HPLC.
Chithunzi 10. Mawonekedwe a data yaiwisi ya 33 mankhwala ophera tizilombo okhala ndi glyphosate ndende ya 21.0-40.5%.
Chithunzi 11. Grafu yolumikizana pakati pa glyphosate yomwe idanenedweratu ndi Vis-NIRS ndi mtengo wamawu woyesedwa ndi HPLC.
Miyezo iyi yolumikizana kwambiri pakati pa mtengo wamawu ndi mtengo wowerengedwa pogwiritsa ntchito Vis-NIRS ikuwonetsa kuti ndi njira yodalirika komanso yachangu kwambiri pakuwongolera khalidwe la mankhwala ophera tizilombo poyerekeza ndi njira ya HPLC yomwe imagwiritsidwa ntchito kale.Chifukwa chake, Vis-NIRS itha kugwiritsidwa ntchito ngati njira ina yopangira chromatography yamadzimadzi yochita bwino kwambiri pakuwunika kwanthawi zonse kwa mankhwala ophera tizilombo ndipo imatha kusunga nthawi ndi ndalama.
