Uphononongo lwangoMvulo lubonise ukuba ukusebenzisa impahla enyangiweyo yi-permethrin ukuthintela ukulunywa ziincukuthu, nto leyo enokubangela izifo ezahlukeneyo ezinzulu.
I-PERMETHRIN sisibulali-zinambuzane esenziwe ngokwenziwa esifana nesakhi sendalo esifumaneka kwi-chrysanthemums. Uphando olwapapashwa ngoMeyi lufumanise ukuba ukutshiza i-permethrin kwimpahla kuyayithintela ngokukhawuleza iimpukane, nto leyo ethintela ukuba zingalumi.
“I-Permethrin inetyhefu kakhulu kwiikati,” wabhala uCharles Fisher, ohlala eChapel Hill, eNC, “ngaphandle kwesilumkiso sokuba abantu mabatshize i-permethrin kwiimpahla ukuze bakhuseleke kwiinkowane. Ukulunywa zizinambuzane kuyingozi kakhulu.”
Abanye bayavuma. “I-NPR ibisoloko ingumthombo omkhulu wolwazi olubalulekileyo,” wabhala uColleen Scott Jackson waseJacksonville, eNorth Carolina. “Ndiyayithiya into yokubona iikati zihlupheka kuba ulwazi olubalulekileyo lushiywe ngaphandle kweli bali.”
Kakade ke, besingafuni ukuba kubekho ntlekele yekati, ngoko ke sagqiba ekubeni sijonge phambili kule ngxaki. Nantsi into esiyifumeneyo.
Iingcali zezilwanyana zithi iikati zinovelwano kakhulu kwi-permethrin kunezinye izilwanyana ezincancisayo, kodwa abathandi beekati basenokusebenzisa isibulali-zinambuzane ukuba balumkile.
“Kuveliswa iidosi ezinetyhefu,” utshilo uGqr. Charlotte Means, umlawuli we-toxicology kwi-ASPCA Animal Poison Control Center.
Ingxaki enkulu iikati ezijongene nayo kuxa zivezwa kwiimveliso ezine-PERMETHRIN ephezulu eyenzelwe izinja, utshilo. Ezi mveliso zinokuba ne-permethrin engama-45% nangaphezulu.
“Ezinye iikati zibuthathaka kangangokuba nokuba ukudibana ngengozi nenja enyangiweyo kunokwanela ukubangela iimpawu zonyango, kuquka ukungcangcazela, ukuxhuzula, kwaye kwiimeko ezimbi kakhulu, ukufa,” utshilo.
Kodwa uxinaniso lwe-permethrin kwii-spray zasekhaya luphantsi kakhulu—ngokuqhelekileyo lungaphantsi kwe-1%. Iingxaki azifane zenzeke xa uxinaniso lwe-5% okanye ngaphantsi, utshilo uMeans.
“Ewe kona, ungasoloko ufumana izilwanyana ezisengozini ngakumbi (iikati), kodwa kwizilwanyana ezininzi iimpawu zeklinikhi zincinci,” utshilo.
“Musa ukunika iikati zakho ukutya kwezinja,” utshilo uGqr. Lisa Murphy, uprofesa oncedisayo we-toxicology kwiSikolo sezonyango lwezilwanyana kwiYunivesithi yasePennsylvania. Uyavuma ukuba imeko eyingozi kakhulu kwiikati kukuvezwa ngengozi kwiimveliso ezixineneyo ezenzelwe izinja.
“Kubonakala ngathi iikati azinayo enye yeendlela eziphambili zokunyibilikisa i-PERMETHRIN,” nto leyo eyenza ukuba zibe sesichengeni ngakumbi semiphumo yekhemikhali, utshilo. Ukuba izilwanyana “azikwazi ukuyinyibilikisa, ukuyiqhekeza nokuyikhupha ngokufanelekileyo, inokuqokelelana kwaye ibe nokwenzeka ngakumbi ukubangela iingxaki.”
Ukuba ukhathazekile kukuba ikati yakho isenokuba ifumene i-permethrin, ezona mpawu zixhaphakileyo kukurhawuzelelwa lusu—ukuba bomvu, ukurhawuzelelwa, kunye nezinye iimpawu zokungakhululeki.
“Izilwanyana zingaphambana ukuba zinento embi eluswini lwazo,” utshilo uMurphy. “Zisenokukrwela, zimbe kwaye ziqengqeleke kuba azikhululekanga.”
Ezi mpendulo zesikhumba zihlala zilula ukuzinyanga ngokuhlamba indawo echaphazelekayo ngesepha yokuhlamba izitya ethambileyo. Ukuba ikati ayivumi, ingasiwa kugqirha wezilwanyana ukuze ihlanjwe.
Ezinye iindlela omele uziqaphele kukuvuza amathe okanye ukuchukumisa umlomo wakho. “Iikati zibonakala ngathi zinovelwano kakhulu kwincasa embi emlonyeni wazo,” utshilo uMurphy. Ukuhlambulula umlomo kancinci okanye ukunika ikati yakho amanzi okanye ubisi ukususa ivumba kunokunceda.
Kodwa ukuba ubona iimpawu zeengxaki zemithambo-luvo—ukungcangcazela, ukushukuma, okanye ukungcangcazela—kufuneka uyise ikati yakho kugqirha wezilwanyana ngokukhawuleza.
Nangona kunjalo, ukuba akukho ngxaki, "ithemba lokuba uza kuphila ngokupheleleyo lilungile," utshilo uMurphy.
“Njengogqirha wezilwanyana, ndicinga ukuba konke kuxhomekeke ekukhetheni,” utshilo uMurphy. Iincukuthu, iintakumba, iintwala kunye neengcongconi zithwala izifo ezininzi, kwaye i-permethrin kunye nezinye izibulali-zinambuzane zinokunceda ekuthinteleni, utshilo: “Asifuni ukuba sigqibela sinezifo ezininzi kuthi okanye kwizilwanyana zethu zasekhaya.”
Ngoko ke, xa kufikwa ekuthinteleni ukulunywa yi-permethrin kunye neempukane, ingongoma ephambili yile: ukuba unekati, lumka kakhulu.
Ukuba uza kutshiza impahla, yenza oku kude neekati. Vumela impahla yome ngokupheleleyo ngaphambi kokuba wena nekati yakho nidibane kwakhona.
“Ukuba utshiza i-1% kwimpahla ize yome, akunakwenzeka ukuba uqaphele naziphi na iingxaki ngekati yakho,” utshilo uMeans.
Lumka kakhulu ungabeki impahla efakwe i-permethrin kufutshane nendawo elele kuyo ikati yakho. Soloko utshintsha impahla emva kokuphuma endlwini ukuze ikati yakho ikwazi ukutsiba emathangeni akho ngaphandle kokukhathazeka, utshilo.
Oku kungabonakala kucacile, kodwa ukuba usebenzisa i-PERMETHRIN ukumanzisa impahla, qiniseka ukuba ikati yakho ayiseli amanzi akwibhakethi.
Okokugqibela, funda ilebheli yemveliso yepermethrin oyisebenzisayo. Jonga ubungakanani bayo kwaye uyisebenzise kuphela njengoko kuyalelwe. Nxibelelana nogqirha wezilwanyana ngaphambi kokuba unyange nasiphi na isilwanyana ngokuthe ngqo ngesibulali-zinambuzane.
