Isingeniso:
I-Meperfluthriniyisibulala-zinambuzane esivame ukusetshenziswa esithole ukunakwa okuphawulekayo ngenxa yokuphumelela kwayo ekuxosheni nasekuqedeni izinambuzane.Nokho, phakathi nokuphumelela kwayo ekulawuleni izinambuzane, kuye kwaphakama ukukhathazeka mayelana nokulimaza okungase kube khona kubantu.Kulesi sihloko esiphelele, singena ebufakazini besayensi futhi sembule iqiniso mayelana nomthelela we-meperfluthrin empilweni yomuntu.
Ukuqonda i-Meperfluthrin:
I-Meperfluthrin ingeyomndeni we-pyrethroid wezibulala-zinambuzane, ezisetshenziswa kakhulu ezindaweni zazo zokuxosha izinambuzane ezinamandla.Kususelwa embalini ye-chrysanthemum, le nhlanganisela yokwenziwa inekhono eliyingqayizivele lokuphazamisa izinhlelo zezinzwa zezinambuzane, zizenze zikhubazeke futhi ekugcineni zibangele ukufa kwazo.
Ubuthi obuphansi kubantu:
Ucwaningo olunzulu kanye nocwaningo lwe-toxicological lwenziwe ukuze kuhlolwe izingozi zezempilo ezingaba khona ezihlobene nokuchayeka kwe-meperfluthrin kubantu.Imiphumela ibonisa kakhulu ukuthi, uma isetshenziswa ngokuvumelana neziqondiso zokuphepha kanye namanani avamile asendlini, i-meperfluthrin ibeka ingozi encane enhlalakahleni yethu.
Izinyathelo Zokuphepha Eziqinisekisa Impilo Yomuntu:
Izindikimba ezilawulayo, njenge-Environmental Protection Agency (EPA), zisungule imihlahlandlela eqinile yokusetshenziswa nokusetshenziswa kwe-meperfluthrin-based.izibulala-zinambuzaneezindaweni zokuhlala, ezohwebo nezolimo.Le mihlahlandlela ihlanganisa imikhawulo yomthamo, izindlela zokufaka ezinconyiwe, nezinyathelo zokuphepha ukuze kuncishiswe noma yimiphi imiphumela emibi engaba khona empilweni yabantu.
Ukukhathazeka Ngokuphefumula kanye Nokuvezwa Kokuphefumula:
Okunye okukhathazayo okuvame ukuphakanyiswa ukuthi kungenzeka kube nomthelela wokuphefumula we-meperfluthrin.Ukuchayeka ekuhogeleni kungase kwenzeke uma kusetshenziswa izifutho ze-aerosol noma eminye imikhiqizo equkethe i-meperfluthrin.Kodwa-ke, kubalulekile ukuqaphela ukuthi ukugxila okuvame ukusetshenziswa emikhiqizweni enjalo kungaphansi kwamazinga athathwa njengeyingozi ezinhlelweni zokuphefumula zabantu.Ukuze kuqhutshekwe nokunciphisa noma yiziphi izingozi ezingase zibe khona, kuyatuseka ukuthi uqinisekise ukungena komoya ngendlela efanele ngesikhathi sokusetshenziswa kwezibulala-zinambuzane ezine-meperfluthrin.
Ukucasuka kwesikhumba kanye nokuzwela:
Esinye isici somthelela we-meperfluthrin empilweni yomuntu siphathelene nokuthintana kwesikhumba.Nakuba ukuthintana ngqo nalesi sibulali zinambuzane kungase kubangele ukucasuka kwesikhumba kubantu abanesikhumba esibucayi, ukungezwani okunamandla noma ukuzwela kuyivelakancane.Kodwa-ke, ukuthatha izinyathelo zokuphepha ezijwayelekile njengokugqoka amagilavu nemikhono emide uma usebenzisa imikhiqizo esekwe ku-meperfluthrin kunganciphisa ngempumelelo lokhu kukhathazeka.
Ukungenwa Ngengozi Nobuthi:
Ukukhathazeka okuphathelene nokungeniswa kwe-meperfluthrin ngephutha kuye kwabhekwana nazo ezifundweni zesayensi.Ucwaningo luveza ngokungaguquguquki ukuthi, noma kwenzeka kuphuzwa ngephutha, imiphumela yobuthi ye-meperfluthrin kubantu iphansi.Noma kunjalo, kubalulekile ukuqapha nokuqinisekisa ukugcinwa okufanele kwayo yonke imikhiqizo equkethe isibulala-zinambuzane, ikakhulukazi emakhaya anezingane ezincane.
Umthelela Wemvelo:
Nakuba lesi sihloko sigxile kakhulu ekulimaleni okungaba khona kwe-meperfluthrin kubantu, kuhle ukubalula umthelela wayo kwezemvelo.I-Meperfluthrinkwaziwa ukuthi iphumelela kakhulu ekulweni nezinambuzane, kodwa futhi inokuphikelela okuphansi kwemvelo uma kuqhathaniswa nezinye izibulala-zinambuzane.Lokhu kunciphisa ingcuphe yokunqwabelana kwesikhathi eside kuma-ecosystem, ngaleyo ndlela kunciphise imiphumela yayo emibi engaba khona ezintweni ezingahlosiwe kanye nemvelo iyonke.
Isiphetho:
Ngocwaningo olubanzi, kuyabonakala ukuthi uma isetshenziswa ngokuzibophezela nangokuhambisana neziqondiso zokuphepha, izibulala-zinambuzane ezisekelwe ku-meperfluthrin ziyingozi encane empilweni yabantu.Ubuthi obuphansi, izinyathelo ezifanele zokuphepha, nemithetho eqinile ezungeze i-meperfluthrin kunomthelela kuyo yonke iphrofayela yayo yokuphepha.Njengenjwayelo, kuyanconywa ukuthi ufunde futhi ulandele imiyalelo yelebula kunoma yimuphi umkhiqizo oqukethe i-meperfluthrin ukuze uqinisekise ukuphepha okukhulu phakathi nokusetshenziswa kwawo.
