Ngokuhlwa, awunakuhlala everanda uze usele ikomityi yeti okanye uchithe ixesha elithile ebaleni, akunjalo? Akunamsebenzi ukuba zeziphi iingxaki ezinje ngeengcongconi, eziqala ukugquma ezindlebeni zakho zize ziqale ukuluma nokukrwela umzimba wonke. Le ngxaki ayipheleli nje ekurhawuzeleni. Ezi ngcongconi zikwadlulisela izifo ezahlukeneyo kubantu abangaphezu kwezigidi ezingama-700 minyaka le. Ngoko ke, makhe sibone indlela esinokuzisindisa ngayo etafileni yesidlo sangokuhlwa sezi ngcongconi.
Kutheni iingcongconi zikhathaza abanye abantu ngakumbi?
Ngaba wakha waziva ngolu hlobo? Ngaba uvakalelwa kukuba iingcongconi zikuluma ngaphezu kwabantu abakungqongileyo? Asikuko nje iimvakalelo zakho.
I-chemistry yomzimba womntu wonke yahlukile kancinci. Yiyo loo nto iingcongconi zitsaleleka ngakumbi kwizinto ezithile eziphuma emizimbeni yethu. Cinga ngako, xa ukhupha umoya, ukhupha igesi yekhabhoni-dayoksayidi . Kwaye ulusu lwakho lukhupha nenye yale gesi. Iingcongconi zinokulivumba eli carbon dioksayidi zikude.
Ayipheleli apho, kodwa ubushushu bomzimba wakho, iikhemikhali ezithile ekubileni kwakho, kunye nendlela ohambahamba ngayo zonke ziimpawu ezinceda iingcongconi zikufumane. Zilandela le ndlela yevumba ukuze zikufumane kwaye zikulume.
I-DEET nezinto zendalo: sesiphi isisombululo esingcono?
Ngamafutshane, isixovuli seengcongconi sisebenza ngokufihla ivumba leekhemikhali emizimbeni yethu elinceda iingcongconi zisifumane. Nangona kukho iintlobo ngeentlobo zezixhobo zokuxovula iingcongconi ezithengiswayo, masithethe ngezona zisebenzayo nezingqinisisiweyo ngophando.
DEET: Inamandla, kodwa ikhuselekile ngokwenene?
I-DEET yeyona ndlela indala nesebenzayo yokugxotha iingcongconi kwimarike. Yaziswa emkhosini wase-US ngo-1946 yaza yamkelwa ukuba isetyenziswe ngokubanzi ngo-1957. Nangona kukho izinto ezintsha ezininzi eziye zavela ukususela ngoko, zimbalwa iimveliso ezikwazileyo ukulingana nokusebenza kwe-DEET.
Enyanisweni, kwaneZiko lase-US loLawulo nokuThintela izifo (i-CDC) licebisa i-DEET njengenye yezithako ezimbini eziphambili zokuthintela izifo ezithwalwa ziingcongconi. Esinye yiPicaridin.
Abantu abaninzi bayayoyika i-DEET, becinga ukuba ifana nesibulali-zinambuzane i-DDT. Kodwa akukho nxibelelwano phakathi kwezi zimbini. I-DEET ayizibulali izinambuzane, iyazigcina kude.
Kwane-Arhente yoKhuseleko lweNdalo yase-US (i-EPA) iphinde yahlola i-DEET yaza yaqinisekisa ukuba i-DEET ikhuselekile kakhulu xa isetyenziswa ngokuchanekileyo ngokwemiyalelo ekwileyibhile.Kwaye ayibalwa njenge-carcinogen.
Nantsi indlela yokusebenzisa i-DEET ngokuchanekileyo:
- Musa ukuyifaka eluswini olungaphantsi kwempahla. Soloko uyifaka kuphela eluswini olungabonakaliyo olungagqunywanga yimpahla . Ukuyifaka phantsi kwempahla kunokubangela ukufunxwa okungakumbi eluswini kwaye mhlawumbi kubangele ukunganyamezelani nolusu .
- Lumka ungakufumani emehlweni akho.
- Ukuyisebenzisa kube kanye ngemini kudla ngokwanela.
Ngaba abantwana abancinci bangakwazi ukusebenzisa i-DEET?
Lo ngumbuzo abazali abaninzi abanawo. Ngokutsho kwe-American Academy of Pediatrics (AAP), kukhuselekile ukusebenzisa iimveliso ezine-DEET kwiintsana ezingaphezulu kweenyanga ezi-2 ubudala . Nangona kunjalo, ubuninzi be-DEET kwimveliso esetyenzisiweyo akufuneki budlule kwi-30%. Akukho myalelo wokugxotha iingcongconi okhuthazwayo kwiintsana ezingaphantsi kweenyanga ezi-2 ubudala. Musa ukuvumela abantwana abancinci ukuba bazisebenzise zodwa; zifake wena eluswini lwabo olubonakalayo.
Ukukhuselwa kwizithako zendalo
Abanye abantu bakhetha ukusebenzisa iimveliso zendalo kune-DEET. Kukwakho nentetho ngeoyile yokuhlamba ye-Avon's Skin-So-Soft, esetyenziswa ngabanye abantu. Nangona kunjalo, uphando lubonise ukuba ukhuseleko lwayo lukhawulelwe kwimizuzu eli-10.
| Uhlobo lokugxotha | Ixesha eliphakathi lokhuseleko (ngokophando) |
|---|---|
| Iimveliso ezine-24% DEET (umz. OFF! Deep Woods) | Malunga neeyure ezi-5 |
| Iimveliso eziqulethe i-2% yeoyile yesoya (umz. i-Bite Blocker yabantwana) | Malunga neyure eyi-1.5 (imizuzu engama-94) |
| Ioyile yokuhlamba ethambileyo kakhulu elusu ka-Avon | Malunga nemizuzu eli-10 |
| Iibhanti zesandla ezine-DEET okanye iCitronella | Akukho khuseleko luninzi kangako . |
Eyona nto ibalulekileyo kukuba isixovuli seengcongconi sisebenza kuphela kulusu esilufakwe kulo. Nokuba unebhandana engalweni yakho, asiyi kukuthintela ekulumeni umlenze wakho.
Amakhandlela eCitronella, iiMosquito Traps, kunye neeBug Zappers - Ngaba Ezi Ziyasebenza Ngokwenene?
Ngaphandle kwezinto esizinxibayo, kukwakho nezixhobo esizisebenzisayo ukugxotha iingcongconi ezisingqongileyo. Makhe sibone ukuba zisebenza kangakanani.
- Amakhandlela eCitronella: La aneminyaka engaphezu kwe-100 ubudala. Nangona kunjalo, uphando oluthile lubonisa ukuba awahlukanga kwiikhandlela eziqhelekileyo, njengoko amakhandlela aqhelekileyo ekhupha ubushushu, ukufuma kunye nekharbon diokside.
- Izixhobo ze-Ultrasonic: Uphando luye lwabonisa ukuba ezi zixhobo zikhupha izandi eziphezulu nezithi zigxotha iingcongconi azisebenzi konke konke.
- Iingcongconi: Ezi zixhobo zikhupha ikhemikhali ebizwa ngokuba yi-'Carbon Dioxide' kunye ne-'Octenol', etsala iingcongconi ize izibambe ngaphakathi kwingcongconi. Nangona ezi zinokubamba inani elikhulu leengcongconi, akucaci nokuba ziyalinciphisa na inani leengcongconi eziluma umntu okufutshane.
- IiBug Zappers (izixovuli zezibane eziluhlaza okwesibhakabhaka): Musa ukuzisebenzisa kwaphela ezi. Nangona ukukhanya okuluhlaza kutsala ezinye izinambuzane, iingcongconi azibonakali zikhathalele. Ngoko ke ezi zibulala izinambuzane eziluncedo nezingenabungozi ezibalulekileyo kwindalo esingqongileyo.
Ukuthintela yeyona nto ilungileyo: Masiyeke ukuzalelana kweengcongconi!
Ngaphezu kokugubungela umzimba wakho, eyona ndlela ilungileyo nethembekileyo yokuzikhusela kwiingcongconi kukuphelisa iindawo zokuzalela kweengcongconi. Olu luxanduva lwethu sonke, ingakumbi kwilizwe lethu, apho kukho ubhubhane we-dengue .
Iingcongconi zibeka amaqanda azo emanzini amileyo. Ezinye iintlobo zeengcongconi zibeka amaqanda azo ngqo emanzini. Ezinye iintlobo zibeka amaqanda azo eludongeni, kwiindawo ezifana namatayara, amaqokobhe ekhokhonathi, iitini ezilahliweyo, iziseko zeembiza zeentyatyambo, kunye neziqu zemithi, ngaphezulu nje komgangatho wamanzi. Kamva, xa lina imvula, amanzi ayazalisa, kwaye iingcongconi ezincinci ziqandusela kula maqanda.
Ngoko ke, akwanelanga nje ukukhupha amanzi kwisikhongozeli esinamanzi aqokeleleneyo. Amaqanda eengcongconi anamathele eludongeni lwesikhongozeli awayi kususwa. Ngoko ke, kubalulekile ukuhlamba kakuhle ezo zikhongozeli.
Soloko ugcina igadi yakho kunye neyadi yakho icocekile. Lumka kuyo nayiphi na indawo apho amanzi anokuqokelelwa khona. Kwakhona qaphela iigutter kunye nezivalo zeetanki zamanzi.
Yintoni omawuyenze xa kukho imeko engxamisekileyo?
Ukuba umntwana ngempazamo uginye into efana ne-inconvenient repellent, mthathe ngoko nangoko aye kwiSebe lezeMpilo eziNgxamisekileyo (ETU) lesibhedlele esikufutshane. Kubalulekile nokufowunela iZiko leSizwe loLwazi ngeePoison kwiSibhedlele sikaZwelonke saseColombo ukuze ufumane ingcebiso engaphezulu. Ukuba kuvela irhashalala elukhumbeni okanye enye ingxaki, qhagamshelana nogqirha wakho ukuze ufumane ingcebiso.
Umyalezo Wokuya Ekhaya
- Uphando lubonisa ukuba isithako esisebenzayo sokugxotha iingcongconi yi -DEET , kwaye sikhuselekile kakhulu xa sisetyenziswa ngokwemiyalelo yeleyibhile.
- Isixovuli seengcongconi masisetyenziswe kuphela kulusu oluvezwe elubala , singagqunywa zimpahla. Kuphephe ukudibana namehlo namlomo.
- Iimveliso ezinomlinganiselo we-DEET we-30% okanye ngaphantsi zikhuselekile ukusetyenziswa kubantwana abangaphezu kweenyanga ezi-2 ubudala . Azifanelekanga ukusetyenziswa kwiintsana ezingaphantsi kweenyanga ezi-2 ubudala.
- Amakhandlela eCitronella, iibhanti zesandla, kunye nezixhobo ze-ultrasonic zibonelela ngokhuseleko oluncinci okanye alunalo kwaphela.
- Eyona ndlela ilungileyo neqinisekileyo yokuphepha iingcongconi kukugcina ikhaya lakho kunye neendawo ezikufutshane zicocekile kwaye utshabalalise iindawo zokuzalela iingcongconi .
