Silinganise amanqanaba omchamo we-3-phenoxybenzoic acid (3-PBA), i-metabolite ye-pyrethroid, kubantu abadala baseKorea abasemaphandleni nasezidolophini abayi-1239. Sikwahlolisise ukuvezwa kwe-pyrethroid sisebenzisa umthombo wedatha wemibuzo;
Isibulali-zinambuzane sasekhayaizitshizi zingumthombo omkhulu wokuvezwa kwe-pyrethroids kuluntu phakathi kwabantu abadala eMzantsi Korea, zilumkisa ngemfuneko yokulawula ngakumbi izinto ezingqongileyo ezihlala zichaphazeleka kuzo ii-pyrethroids, kuquka izitshizi zezibulala-zinambuzane.
Ngenxa yezi zizathu, ukufunda ngemiphumo ye-pyrethroids kubantu abadala kunokuba yinto ebalulekileyo eKorea nakwamanye amazwe anenani labantu abadala abakhula ngokukhawuleza. Nangona kunjalo, kukho inani elincinci lezifundo ezithelekisa ukuvezwa kwe-pyrethroid okanye amanqanaba e-3-PBA kubantu abadala abakwiindawo zasemaphandleni okanye ezidolophini, kwaye zimbalwa izifundo ezixela iindlela ezinokubakho zokuvezwa kunye nemithombo enokubakho yokuvezwa.
Ngoko ke, silinganise amanqanaba e-3-PBA kwiisampuli zomchamo zabantu abadala eKorea saza sathelekisa amanqanaba e-3-PBA kumchamo wabantu abadala basemaphandleni nasezidolophini. Ukongeza, sivavanye umlinganiselo odlula imida yangoku ukuze simisele ukuvezwa kwe-pyrethroid phakathi kwabantu abadala eKorea. Sivavanye nemithombo enokubakho yokuvezwa kwe-pyrethroid sisebenzisa imibuzo kwaye sayidibanisa namanqanaba e-3-PBA kumchamo.
Kolu phononongo, silinganise amanqanaba e-3-PBA yomchamo kubantu abadala baseKorea abahlala kwiindawo zasemaphandleni nasezidolophini saza sahlola ubudlelwane phakathi kwemithombo enokubakho yokuvezwa yi-pyrethroid kunye namanqanaba e-3-PBA yomchamo. Sikwafumanise umlinganiselo wokugqithisa kwemida ekhoyo saza savavanya umahluko phakathi kwabantu ngabanye kunye nowangaphakathi kumanqanaba e-3-PBA.
Kwisifundo esapapashwa ngaphambili, sifumene ulwalamano olubalulekileyo phakathi kwamanqanaba e-3-PBA yomchamo kunye nokwehla komsebenzi wamaphaphu kubantu abadala basezidolophini eMzantsi Korea [3]. Ngenxa yokuba sifumanise ukuba abantu abadala basezidolophini baseKorea babechatshazelwe kumanqanaba aphezulu e-pyrethroids kwisifundo sethu sangaphambili [3], siqhubeke sithelekisa amanqanaba e-3-PBA yomchamo kubantu abadala basemaphandleni nasezidolophini ukuze sivavanye ubungakanani bamaxabiso e-pyrethroid agqithisileyo. Olu phononongo luvavanye imithombo enokubakho yokuvezwa kwe-pyrethroid.
Uphononongo lwethu lunamandla aliqela. Sisebenzise ukulinganisa okuphindaphindiweyo kwe-3-PBA yomchamo ukubonisa ukuvezwa kwe-pyrethroid. Olu yilo lwephaneli olude lunokubonisa utshintsho lwexesha ekubonakalisweni kwe-pyrethroid, olunokutshintsha ngokulula ngokuhamba kwexesha. Ukongeza, ngolu yilo lophononongo, singahlola isifundo ngasinye njengolawulo lwaso kwaye sivavanye iziphumo zexesha elifutshane zokuvezwa kwe-pyrethroid sisebenzisa i-3-PBA njenge-covariate yexesha ngaphakathi kwabantu. Ukongeza, besingabantu bokuqala ukuchonga imithombo yendalo (engeyiyo yomsebenzi) yokuvezwa kwe-pyrethroid kubantu abadala eKorea. Nangona kunjalo, uphando lwethu lukwanazo nemida. Kolu phononongo, siqokelele ulwazi malunga nokusetyenziswa kwe-sprays yokubulala izinambuzane sisebenzisa iphepha lemibuzo, ngoko ke ixesha eliphakathi kokusetyenziswa kwe-sprays yokubulala izinambuzane kunye nokuqokelelwa komchamo alikwazanga ukuqinisekiswa. Nangona iipatheni zokuziphatha zokusetyenziswa kwe-spray yokubulala izinambuzane zingatshintshi lula, ngenxa yemetabolism ekhawulezayo ye-pyrethroid emzimbeni womntu, ixesha eliphakathi kokusetyenziswa kwe-spray yokubulala izinambuzane kunye nokuqokelelwa komchamo linokuchaphazela kakhulu amazinga e-3-PBA yomchamo. Ukongeza, abathathi-nxaxheba bethu babengameli kuba sigxile kwindawo enye yasemaphandleni nenye yasezidolophini, nangona amanqanaba ethu e-3-PBA ayefana nalawo alinganiswe kubantu abadala, kuquka nabantu abadala, kwiKoNEHS. Ke ngoko, eminye imithombo yokusingqongileyo enxulumene nokuvezwa kwe-pyrethroid kufuneka ifundwe ngakumbi kubantu abadala abameleyo.
Ngoko ke, abantu abadala eKorea bachanabeka kubuninzi be-pyrethroids, kwaye ukusetyenziswa kwezitshizi zokubulala izinambuzane kungumthombo ophambili wokuvezwa kwindalo esingqongileyo. Ngoko ke, uphando olongezelelekileyo luyafuneka kwimithombo yokuvezwa kwe-pyrethroid kubantu abadala eKorea, kwaye kufuneka ulawulo oluqinileyo kwizinto ezihlala zibonakala kwindalo esingqongileyo, kuquka ukusetyenziswa kwezitshizi zokubulala izinambuzane, ukukhusela abantu abachanabeka kwi-pyrethroids, kuquka ukuvezwa kwiikhemikhali zokusingqongileyo.
