Ucwaningo lwangoMsombuluko luveze ukuthi ukusebenzisa izingubo ezifakwe i-permethrin ukuvikela ukulunywa kwemikhaza, okungadala izifo ezahlukahlukene.
I-PERMETHRIN iyisibulala-zinambuzane sokwenziwa esifana nenhlanganisela yemvelo etholakala kuma-chrysanthemums.Ucwaningo olwanyatheliswa ngoMeyi lwathola ukuthi ukufafaza i-permethrin engutsheni ngokushesha kwakhubaza imikhaza, kwabavimbela ukuba balume.
“I-Permethrin inobuthi obukhulu emakatini,” kubhala uCharles Fisher, ohlala e-Chapel Hill, NC, “ngaphandle kombhalo wokuphika otusa ukuba abantu bafafaze i-permetrin engutsheni ukuze bavikele imikhaza.Ukulunywa yizinambuzane kuyingozi kakhulu.”
Abanye bayavuma.“I-NPR ibilokhu ingumthombo omuhle wolwazi olubalulekile,” kubhala uColleen Scott Jackson waseJacksonville, eNyakatho neCarolina."Ngiyakuzonda ukubona amakati ehlupheka ngoba ulwazi olubalulekile lushiywe ngaphandle endabeni."
Yebo, sasingafuni ukuthi kwenzeke izinhlekelele zamakati, ngakho sanquma ukubhekisisa lolu daba.Nakhu esikutholile.
Odokotela bezilwane bathi amakati azwela kakhulu i-permetrin kunezinye izilwane ezincelisayo, kodwa abathandi bamakati basengasebenzisa isibulala-zinambuzane uma beqaphela.
“Kukhiqizwa imithamo enobuthi,” kusho uDkt. Charlotte Means, umqondisi wesayensi yezobuthi e-ASPCA Animal Poison Control Center.
Inkinga enkulu amakati abhekana nayo yilapho echayeka emikhiqizweni enezinga eliphezulu le-PERMETHRIN eyenzelwe izinja, esho.Le mikhiqizo ingase ibe no-45% we-permetrin noma ngaphezulu.
“Amanye amakati azwela kangangokuthi ngisho nokuthintana nenja ngephutha kungase kubangele izimpawu zomtholampilo, kuhlanganise nokundindizela, ukuquleka, futhi, ezimweni ezimbi kakhulu, ukufa,” kusho yena.
Kodwa ukuhlushwa kwe-permetrin ezifutheni zasendlini kuphansi kakhulu-imvamisa kungaphansi kwe-1%.Izinkinga azivamile ukwenzeka lapho kugxilwa khona ngamaphesenti angu-5 noma ngaphansi, kusho uMeans.
“Yebo, ungahlala uthola abantu abasengozini enkulu (amakati), kodwa ezilwaneni eziningi izimpawu zomtholampilo zincane kakhulu,” kusho yena.
“Ungawaniki amakati akho ukudla kwenja,” kusho uDkt. Lisa Murphy, umsizi kaprofesa we-toxicology e-University of Pennsylvania School of Veterinary Medicine.Uyavuma ukuthi isimo esiyingozi kakhulu kumakati ukuchayeka ngephutha emikhiqizweni egxiliswe kakhulu ehloselwe izinja.
"Amakati abonakala entula enye yezindlela eziyinhloko zokusebenzisa i-PERMETHRIN," ezenza zibe lula emiphumeleni yamakhemikhali, esho.Uma izilwane “zingakwazi ukugawula umzimba, ziwuphule futhi ziwukhiphe ngendlela efanele, zinganqwabelana futhi zibe sengozini yokubangela izinkinga.”
Uma ukhathazekile ngokuthi ikati lakho lingase livezwe ku-permetrin, izimpawu ezivame kakhulu ukucasuka kwesikhumba-ubomvu, ukulunywa, nezinye izimpawu zokungakhululeki.
“Izilwane zingahlanya uma zinento embi esikhumbeni sazo,” kusho uMurphy.“Bangase bazinwaye, bambe futhi baziginqike ngoba akulungile.”
Lokhu kusabela kwesikhumba ngokuvamile kulula ukukwelapha ngokugeza indawo ethintekile ngensipho ewuketshezi yokugeza izitsha.Uma ikati liphika, lingayiswa kudokotela wezilwane ukuze liyogezwa.
Okunye ukusabela okufanele ukubuke ukuconsa amathe noma ukuthinta umlomo wakho.“Amakati abonakala ezwela kakhulu ukunambitheka okubi emlonyeni wawo,” kusho uMurphy.Ukugeza umlomo ngobumnene noma ukunikeza ikati lakho amanzi noma ubisi ukuze ukhiphe iphunga kungasiza.
Kodwa uma ubona izimpawu zezinkinga zezinzwa—ukundindizela, ukudikiza, noma ukuthuthumela—kufanele uthathe ikati lakho uye kudokotela wezilwane ngokushesha.
Noma kunjalo, uma zingekho izinkinga, "ukubikezelwa kokululama okuphelele kuhle," kusho uMurphy.
“Njengodokotela wezilwane, ngicabanga ukuthi konke kumayelana nokuzikhethela,” kusho uMurphy.Imikhaza, amazeze, izintwala nomiyane zithwala izifo eziningi, futhi i-permethrin nezinye izibulala-zinambuzane zingasiza ekuvimbeleni, wathi: “Asifuni ekugcineni sinezifo eziningi kithi noma ezifuyweni zethu.”
Ngakho-ke, uma kuziwa ekuvimbeleni i-permetrin kanye nokulunywa komkhaza, iphuzu elibalulekile yilokhu: uma unekati, qaphela kakhulu.
Uma uzofutha izingubo, kwenze lapho ungafinyeleli khona amakati.Vumela izingubo zome ngokuphelele ngaphambi kokuba wena nekati lakho nihlangane.
“Uma ufutha iphesenti elingu-1 engutsheni bese yoma, cishe ngeke ubone izinkinga ngekati lakho,” kusho uMeans.
Qaphela ikakhulukazi ukuthi ungabeki izingubo ezine-permetrin eduze nalapho ikati lakho lilala khona.Hlala ushintsha izingubo ngemva kokuphuma endlini ukuze ikati lakho ligxumele emathangeni akho ngaphandle kokukhathazeka, esho.
Lokhu kungase kubonakale kusobala, kodwa uma usebenzisa i-PERMETHRIN ukucwilisa izingubo, qiniseka ukuthi ikati lakho aliwaphuzi amanzi ebhakedeni.
Ekugcineni, funda ilebula yomkhiqizo we-permetrin owusebenzisayo.Hlola ukugxila futhi usebenzise kuphela njengoba kuyalelwe.Xhumana nodokotela wakho wezilwane ngaphambi kokwelapha ngokuqondile noma yisiphi isilwane nganoma yisiphi isibulala-zinambuzane.
