Kusihlwa, awukwazi ukuhlala everanda uphuze itiye noma uchithe isikhathi esithile egcekeni, akunjalo? Akunandaba ukuthi hlobo luni lwenkinga yalezi zimiyane, eziqala ukubhonga ezindlebeni zakho bese ziqala ukuluma nokuklwebha umzimba wonke. Le nkinga ayigcini nje ngokulunywa. Lezi zimiyane ezifanayo zidlulisela nezifo ezahlukahlukene kubantu abangaphezu kwezigidi ezingu-700 minyaka yonke. Ngakho-ke, ake sibone ukuthi singazisindisa kanjani etafuleni lesidlo sakusihlwa salezi zimiyane.
Kungani omiyane behlupha abanye abantu kakhulu?
Wake wazizwa ngale ndlela? Uzizwa sengathi omiyane bakuluma ngaphezu kwabantu abakuzungezile? Akuyona imizwa yakho kuphela.
I-chemistry yomzimba womuntu wonke ihlukile kancane. Yingakho omiyane bekhangwa kakhulu yizinto ezithile eziphuma emizimbeni yethu. Cabanga ngakho, uma ukhipha umoya, ukhipha igesi yekhabhoni dioksijini . Futhi isikhumba sakho sikhipha nenye yale gesi. Omiyane bangawuzwa lo msindo wekhabhoni dioksijini bekude.
Akukhona lokho kuphela, kodwa ukushisa komzimba wakho, amakhemikhali athile ekujulukeni kwakho, kanye nendlela ohamba ngayo konke kuyizimpawu ezisiza omiyane ukuthi bakuthole. Balandela lo mzila wephunga ukuze bakuthole futhi bakulume.
I-DEET nezinto zemvelo: yisiphi ikhambi elingcono kakhulu?
Kalula nje, umuthi wokuxosha omiyane usebenza ngokufihla iphunga lamakhemikhali emizimbeni yethu elisiza omiyane ukuthi basithole. Nakuba kunezinhlobo ezahlukene zemithi yokuxosha omiyane emakethe, ake sixoxe ngemithi ephumelela kakhulu neqinisekisiwe ngocwaningo.
DEET: Inamandla, kodwa iphephile ngempela?
I-DEET iyisixosha-miyane esidala kakhulu nesisebenza kahle kakhulu emakethe. Yalethwa ebuthweni lezempi lase-US ngo-1946 futhi yavunyelwa ukusetshenziswa ngokujwayelekile ngo-1957. Naphezu kwezinto eziningi ezintsha eziye zavela kusukela ngaleso sikhathi, imikhiqizo embalwa eye yakwazi ukuhambisana nokusebenza kwe-DEET.
Eqinisweni, ngisho ne-US Centers for Disease Control and Prevention (CDC) incoma i-DEET njengenye yezithako ezimbili eziyinhloko zokuvimbela izifo ezithwalwa omiyane. Esinye yi-Picaridin.
Abantu abaningi bayesaba i-DEET, becabanga ukuthi ifana nomuthi wokubulala izinambuzane i-DDT. Kodwa akukho ukuxhumana phakathi kwalokhu okubili. I-DEET ayizibulali izinambuzane, imane izigcina kude.
Ngisho ne-US Environmental Protection Agency (EPA) iphinde yahlola i-DEET futhi yaqinisekisa ukuthi i-DEET iphephile kakhulu uma isetshenziswa kahle ngokwemiyalelo ebhalwe kulebula.Futhi ayihlukaniswa njenge-carcinogen.
Nansi indlela yokusebenzisa i-DEET ngendlela efanele:
- Ungafaki esikhumbeni esingaphansi kwezingubo. Njalo sebenzisa kuphela esikhumbeni esiveziwe esingamboziwe yizingubo . Ukuyifaka ngaphansi kwezingubo kungabangela ukumuncwa okwengeziwe esikhumbeni futhi mhlawumbe kubangele ukungezwani nesikhumba .
- Qaphela ukuthi ungakutholi emehlweni akho.
- Ukuyisebenzisa kanye ngosuku ngokuvamile kwanele.
Ingabe izingane ezincane zingayisebenzisa i-DEET?
Lona umbuzo abazali abaningi abanawo. Ngokusho kwe-American Academy of Pediatrics (AAP), kuphephile ukusebenzisa imikhiqizo equkethe i-DEET ezinganeni ezingaphezu kwezinyanga ezimbili ubudala . Kodwa-ke, ukugcwala kwe-DEET kumkhiqizo osetshenzisiwe akufanele kudlule u-30%. Akukho ukuxosha omiyane okunconywayo ezinganeni ezingaphansi kwezinyanga ezimbili ubudala. Ungavumeli izingane ezincane zizisebenzise zodwa; zifake wena esikhumbeni sazo esiveziwe.
Ukuvikelwa ezithakweni zemvelo
Abanye abantu bakhetha ukusebenzisa imikhiqizo yemvelo kune-DEET. Kukhona futhi izinkulumo ngamafutha okugeza e-Avon's Skin-So-Soft, abanye abantu abawasebenzisayo. Kodwa-ke, ucwaningo lukhombisile ukuthi ukuvikelwa kwawo kunqunyelwe cishe imizuzu eyi-10.
| Uhlobo lokususa izinambuzane | Isikhathi esiphephile esimaphakathi (ngokusho kocwaningo) |
|---|---|
| Imikhiqizo equkethe i-DEET engu-24% (isb. I-OFF! Deep Woods) | Cishe amahora ama-5 |
| Imikhiqizo equkethe uwoyela wesoya ongu-2% (isb. i-Bite Blocker yezingane) | Cishe amahora angu-1.5 (imizuzu engama-94) |
| Amafutha Okugeza Athambile Kakhulu Esikhumba Sase-Avon | Cishe imizuzu eyi-10 |
| Amabhande esihlakaleni aqukethe i-DEET noma i-Citronella | Akukho ukuphepha okuningi. |
Into ebaluleke kakhulu ukuthi umuthi wokuxosha omiyane usebenza kuphela esikhumbeni osigcotshiwe. Ngisho noma unebhandana engalweni yakho, ngeke ukuvimbele ukuluma umlenze wakho.
Amakhandlela e-Citronella, Izicupho Zomiyane, kanye Nezithiyo Zokuvimba Ama-Bug - Ingabe Lokhu Kuyasebenza Ngempela?
Ngaphandle kwezinto esizigqokayo, kukhona namadivayisi esiwasebenzisayo ukuxosha omiyane abasizungezile. Ake sibone ukuthi asebenza kahle kangakanani.
- Amakhandlela e-Citronella: Lawa aneminyaka engaphezu kweyikhulu ubudala. Kodwa-ke, olunye ucwaningo lubonisa ukuthi awahlukile kunamakhandlela avamile, njengoba amakhandlela avamile nawo ekhipha ukushisa okuthile, umswakama kanye ne-carbon dioxide.
- Amadivayisi e-Ultrasonic: Ucwaningo luye lwabonisa ukuthi la madivayisi akhipha imisindo evame kakhulu futhi athi axosha omiyane awasebenzi nhlobo.
- Izicupho Zomiyane: Lawa madivayisi akhipha ikhemikhali ebizwa ngokuthi i-'Carbon Dioxide' kanye ne-'Octenol', edonsela omiyane bese ibabamba ngaphakathi kwesicupho. Nakuba lokhu kungabamba inani elikhulu lomiyane, akucaci ukuthi empeleni kuyalinciphisa yini inani lomiyane abaluma umuntu oseduze.
- Ama-Bug Zappers (imithi yokuxosha ukukhanya okuluhlaza okwesibhakabhaka): Ungazisebenzisi nhlobo lezi zinto. Nakuba ukukhanya okuluhlaza okwesibhakabhaka kudonsela ezinye izinambuzane, omiyane ababonakali bengenandaba. Ngakho-ke lezi zibulala izinambuzane eziwusizo, ezingenangozi ezibalulekile endaweni yethu.
Ukuvimbela kungcono kakhulu: Masiyeke ukuzalanisa omiyane!
Ngaphezu kokumboza umzimba wakho, indlela engcono kakhulu nethembekile yokuzivikela komiyane ukuqeda izindawo zokuzalela komiyane. Lona umthwalo wemfanelo wethu sonke, ikakhulukazi ezweni lakithi, lapho kunesifo sohudo .
Omiyane babekela amaqanda abo emanzini amile. Ezinye izinhlobo zomiyane zibekela amaqanda azo ngqo emanzini. Ezinye izinhlobo zibekela amaqanda azo odongeni, ezindaweni ezifana namathayi, amagobolondo kakhukhunathi, amathini alahliwe, izisekelo zezimbiza zezimbali, kanye neziqu zemithi, ngaphezu nje kwamanzi. Kamuva, lapho lina, amanzi ayagcwala, bese omiyane abasebasha bephuma kula maqanda.
Ngakho-ke, akwanele nje ukukhipha amanzi esitsheni esinamanzi aqongelelekile. Amaqanda omiyane anamathele odongeni lwaleso sitsha ngeke asuswe. Ngakho-ke, kubalulekile ukuwageza kahle lawo mabhodlela.
Gcina ingadi yakho negceke lakho kuhlanzekile ngaso sonke isikhathi. Qaphela noma yiziphi izindawo lapho amanzi anganqwabelana khona. Naka futhi amapayipi kanye nezivalo zamatangi amanzi.
Yini okufanele uyenze uma kunesimo esiphuthumayo?
Uma ingane idla ngephutha into efana nokubulala omiyane, yiyise ngokushesha eMnyangweni Wezimo Eziphuthumayo (ETU) wesibhedlela esiseduze. Kubalulekile futhi ukushayela ucingo iNational Poison Information Centre eColombo National Hospital ukuze uthole iseluleko esengeziwe. Uma kuvela ukuqubuka kwesikhumba noma enye inkinga, xhumana nodokotela wakho ukuze uthole iseluleko.
Umlayezo Wokuya Nawe Ekhaya
- Ucwaningo lubonisa ukuthi isithako esisebenza kahle kakhulu sokuxosha omiyane yi -DEET , futhi siphephile kakhulu uma sisetshenziswa ngokwemiyalelo yelebula.
- Isihlanzi somiyane kufanele sisetshenziswe kuphela esikhumbeni esiveziwe , hhayi simbozwe ngezingubo. Gwema ukuthinta amehlo nomlomo.
- Imikhiqizo enezinga le-DEET elingu-30% noma ngaphansi iphephile ukusetshenziswa ezinganeni ezingaphezu kwezinyanga ezimbili ubudala . Ayifanele ukusetshenziswa ezinganeni ezingaphansi kwezinyanga ezimbili ubudala.
- Amakhandlela e-Citronella, amabhande esihlakaleni, kanye namadivayisi e-ultrasonic anikeza isivikelo esincane noma angabi naso nhlobo.
- Indlela engcono kakhulu neqinisekile yokugwema omiyane ukugcina ikhaya lakho nendawo ezungezile ihlanzekile futhi ubhubhise izindawo zokuzalela omiyane .
