Isishwankathelo

I-DEET (ngesiNgesi i-diethylmethylbenzamide), efinyeziweyo njenge-DEET, igama lekhemikhali yi-diethyltoluamide, yi-Chemicalbook egxotha izinambuzane ezininzi. Inefuthe lokugxotha kwiintlobo ngeentlobo zezinambuzane ezilumayo kwiindawo ezahlukeneyo kwaye inokugxotha izinambuzane ezilumayo. Iimpukane, ii-midges, iimpukane ezimnyama, ii-chiggers, iimpukane zenyamakazi, ii-fleas, ii-gnats, iimpukane zamahashe, iingcongconi, iimpukane zesanti, ii-gnats, iimpukane ezizinzileyo kunye nee-ticks.

I-DEET yaphuhliswa kwaye yanikwa ilungelo elilodwa lomenzi liSebe lezoLimo laseMelika ngexesha leMfazwe Yehlabathi yesiBini. Le mveliso yamiselwa njengemveliso yokugxotha iingcongconi ukuze isetyenziswe ngumkhosi wase-US ngo-1946. Yabhaliswa kwi-US Environmental Protection Agency njengesixhobo sokugxotha izinambuzane ngo-1957 yaza yaqala ukusetyenziswa kuluntu. Ekuqaleni yayisetyenziswa njengesibulali-zinambuzane kwiifama. Kamva, urhulumente wase-US wafaka isicelo sokuyisebenzisa ngexesha leemfazwe, ingakumbi eVietnam nakuMzantsi-mpuma we-Asia. Ngokwezibalo ze-US Environmental Protection Agency, minyaka le iChemicalbook Phantse ama-40% aseMelika asebenzisa isibulali-zinambuzane esine-DEET, esisetyenziswa ngabantu abamalunga nezigidi ezingama-200 kwihlabathi liphela. Kwiminyaka engama-40 edlulileyo, uphando olwenziwe ziiyunithi zophando ezingaphezu kwama-20,000 luye lwabonisa ukuba i-DEET yeyona ndlela ikhuselekileyo nesebenzayo yokugxotha izinambuzane kwimarike. Isibulali-zinambuzane esibanzi. I-World Health Organisation ikwacebisa ukusetyenziswa kweemveliso zokugxotha ezine-DEET ukukhusela kwizinambuzane ezithwalwa zizilwanyana. Idla ngokuxutywa nezinye izibulali-zinambuzane, kodwa ubuthi bayo buyanda xa ixutywe nezibulali-zinambuzane ze-carbamate.
