DEETndechimwe chezvishoma zvinodzinga zvinoonekwa kuti zvinoshanda kurwisa umhutu, zvikwekwe, uye zvimwe zvipembenene zvine njodzi. Asi nekupihwa simba rekemikari iyi, DEET yakachengeteka sei kuvanhu?
DEET, inodaidzwa nevemakemikari kuti N,N-diethyl-m-toluamide, inowanikwa mune zvinosvika zana nemakumi maviri zvigadzirwa zvakanyoreswa neUS Environmental Protection Agency (EPA). Zvigadzirwa izvi zvinosanganisira zvekupfapfaidza zvipembenene, zvipfapfaidzo, mafuta ekuzora, uye zvekupukuta.

Asi Bethany Huelskoetter, APRN, DNP, chiremba wemishonga yemhuri kuOSF Healthcare, anoti vamwe varwere vanonzvenga zvigadzirwa izvi, vachida izvo zvinotengeswa se "zvakasikwa" kana "makwenzi."
Nepo izvi zvimwe zvinodzingisa zvinogona kutengeswa sezvisina muchetura, mhedzisiro yavo yekudzinga kazhinji haigare kwenguva refu seDEET.
”Dzimwe nguva hazvibviri kunzvenga mishonga inodzinga makemikari. DEET inonyatso dzinga. Pane zvese zvinodzinga pamusika, DEET ndiyo yakanakisa kukosha kwemari, "Huelskoetter akaudza Verywell.
Shandisa mushonga wekudzivirira unoshanda kuderedza njodzi yekukwenya uye kusagadzikana kubva pakurumwa netumbuyu. Asi inogona zvakare kuve nzira yekudzivirira yehutano: Vanosvika hafu yemiriyoni vanhu vanova nechirwere cheLyme gore rega rega mushure mekurumwa nechikwekwe, uye vanhu vanofungidzirwa kuti mamirioni manomwe vakagadzira chirwere ichi kubva hutachiona hunotakurwa neumhutu kuWest Nile hwakatanga kuUS muna 1999. Vanhu vane utachiona.
Sekureva kweConsumer Reports, DEET inogara ichitariswa sechinhu chinonyanya kushanda chinoshandiswa mumishonga inodzinga zvipembenene pahuwandu hunosvika 25%. Kazhinji kutaura, iyo yakanyanya kuwanda kweDEET muchigadzirwa, iyo nguva yekudzivirira inogara.
Zvimwe zvinodzinga zvinosanganisira picaridin, permethrin, uye PMD (mafuta eremoni eucalyptus).
Chidzidzo che2023 chakaedza makumi maviri akakosha ekudzoreredza mafuta akawana kuti mafuta akakosha aisagara kwenguva yakareba kupfuura awa nehafu, uye mamwe akarasika kushanda mushure meisingasviki miniti. Kana tichienzanisa, iyo inodzinga DEET inogona kudzinga umhutu kweinenge maawa matanhatu.
Zvinoenderana neAgency for Toxic Substances and Disease Registry (ATSDR), mhedzisiro kubva kuDEET haiwanzo. Mumushumo we2017, iyo agency yakati 88 muzana yekufumurwa kweDEET yakashumwa kunzvimbo dzekutonga chepfu haina kuunza zviratidzo zvinoda kurapwa nehutano hwehutano. Inenge hafu yevanhu havana kuona migumisiro yakaipa, uye vazhinji vevamwe vaingova nezviratidzo zvakapfava, zvakadai sokukotsira, kutsvuka kweganda, kana chikosoro chechinguvana, izvo zvakakurumidza kupera.
Kuita kwakanyanya kuDEET kunowanzo konzera zviratidzo zvetsinga zvakadai sekugwinha, kutadza kudzora tsandanyama, hunhu hwehasha, uye kutadza kuziva.
"Tichifunga kuti mamiriyoni evanhu muUnited States anoshandisa DEET gore negore, kune mishumo shomanana yemigumisiro yakakomba yehutano kubva kuDEET kushandiswa," mushumo weATSDR wakadaro.
Unogonawo kudzivirira kurumwa netumbuyu nokupfeka maoko marefu uye kuchenesa kana kudzivisa chero nzvimbo dzinoberekesa zvipembenene, dzakadai semvura yakamira, chivanze chako, nedzimwe nzvimbo dzaunogara uchiita.
Kana ukasarudza kushandisa chigadzirwa chine DEET, tevera mafambiro ari pachigadzirwa label. Sekureva kweCenters for Disease Control and Prevention, unofanirwa kushandisa iyo yakaderera yeDEET inodiwa kuchengetedza kuchengetedzwa - kwete kupfuura makumi mashanu muzana.
Kuti kuderedze njodzi yekufemesa zvinodzinga, CDC inokurudzira kushandisa zvinodzinga munzvimbo dzine mhepo yakanaka kwete munzvimbo dzakapoteredzwa. Kuisa kumeso kwako, pfapfaidza chigadzirwa pamaoko ako uye wozora kumeso kwako.
Anowedzera kuti: “Unoda kuti ganda rako rikwanise kufema kana waiswa, uye kana ukafefeterwa zvakanaka hauzorwadzisike paganda.”
DEET yakachengeteka kuvana, asi veCenters for Disease Control and Prevention vanokurudzira kuti vana vari pasi pemakore gumi vasazozvizora mishonga yekudzinga. Vana vari pasi pemwedzi miviri yezera havafanirwe kushandisa zvigadzirwa zvine DEET.
Zvakakosha kufonera chepfu inodzora nzvimbo ipapo kana ukafema kana kumedza chigadzirwa chine DEET, kana chigadzirwa chikapinda mumaziso ako.
Kana uri kutsvaga nzira yakavimbika yekudzora tupukanana, kunyanya munzvimbo dzine umhutu nezvikwekwe, DEET isarudzo yakachengeteka uye inoshanda (chero bedzi ichishandiswa maererano neraiti). Zvisarudzo zvechisikigo zvingasapa mwero wakafanana wedziviriro, saka funga nezvemhoteredzo nengozi yezvirwere zvinoparadzirwa nezvipembenene pakusarudza mushonga unodzinga.
