Ulwelo lwe-Diethyltoluamide yesitshabalalisi sasekhaya esineXabiso eliPhezulu kwisitokhwe
Ingcaciso yeMveliso
DEETisetyenziswa kakhulu njengesixhobo sokugxotha izinambuzane zokuzikhusela kwizinambuzane ezilumayo.Sesona sithako sixhaphakileyo kwiisinambuzaneizigxothi kwaye kukholelwa ukuba zisebenza ngolo hlobo kuba iingcongconi azilithandi kakhulu ivumba layo.Kwaye inokuqulunqwa nge-ethanol ukwenza i-15% okanye i-30% ye-diethyltoluamide formulation, okanye ichithe kwi-solvent efanelekileyo kunye ne-vaseline, i-olefin njl.DEETsisibulali-zinambuzane sasekhaya esisebenza kakuhle kakhulu.Isenokusetyenziswa njengesinyibilikisi esisebenzayo kwaye inokunyibilikisa iiplastiki, irayon, ispandex, amanye amalaphu okwenziwa kunye nokupeyintwa okanye ivanishi.
Indlela yokwenza
I-DEET iguquguqukayo kwaye iqulethe ukubila kunye nokuphefumla komntu, isebenza ngokuthintela i-1 octene 3 yotywala yezinambuzane ze-olfactory receptors.Ithiyori edumileyo yeyokuba i-DEET ibangela ukuba izinambuzane ziphulukane nemvakalelo yevumba elikhethekileyo elikhutshwa ngabantu okanye izilwanyana.
Ukuqwalaselwa
1. Musa ukuvumela iimveliso ezine-DEET ukuba zidibane ngqo nesikhumba esonakeleyo okanye zisetyenziswe kwiimpahla;Xa kungafunekiyo, ukuqulunqwa kwayo kunokuhlanjwa ngamanzi.Njengesivuseleli, i-DEET ayinakuphepheka ukuba ibangele ukucaphuka kwesikhumba.
2. I-DEET sisitshabalalisi sekhemikhali esingenamandla nesisenokungafaneleki ukusetyenziswa kwimithombo yamanzi nakwiindawo ezingqongileyo.Ifunyaniswe inetyhefu encinci kwintlanzi yasemanzini abandayo, efana ne-rainbow trout kunye ne-tilapia.Ukongeza, uvavanyo lubonise ukuba ikwayityhefu kwezinye iintlobo zeplanktonic zamanzi acwengileyo.
3. I-DEET ibeka umngcipheko onokubakho kumzimba womntu, ngakumbi abafazi abakhulelweyo: izinto zokugxotha iingcongconi ezine-DEET zinokungena kwigazi emva kokudibana nolusu, ezinokungena kwi-placenta okanye nakwi-umbilical cord ngegazi, okukhokelela kwi-teratogenesis.Abasetyhini abakhulelweyo kufuneka bakuphephe ukusebenzisa iimveliso zokugxotha iingcongconi ezine-DEET.
