• Yini okufanele uyenze uma kwenzeka kukhona okusolwayo okusolwayo
• Izimpawu ze-DDT ushevu wokubulala izinambuzane
• Ungayelapha kanjani i-DDT ushevu
• Nawa amanye amasu emvelo okugcina omiyane bengekho:

Isibulala-zinambuzane se-DDT sinamandla futhi siyasebenza ekulweni nomiyane kamalaleveva, kodwa futhi singadala nokulimala kwezempilo, uma sihlangana nesikhumba noma sihogelwe emoyeni, ngesikhathi sokufafaza ngakho-ke labo abahlala ezindaweni lapho umalaleveva uvame khona futhi lesi sibulali zinambuzane esisetshenziswayo kufanele sigweme ukuhlala ngaphakathi endlini ngosuku okwelashwa ngalo indlu, futhi sigweme ukuthinta izindonga ezivame ukuba mhlophe ngenxa yobuthi.

Yini okufanele uyenze uma kwenzeka kukhona okusolwayo okusolwayo

Uma kwenzeka usola ukungcola, kufanele uye kudokotela ukhombe ngokwenzekile nezimpawu onazo. Udokotela anga-oda ukuhlolwa ukuthola ukuthi ngabe bekukhona ukungcola, ukuthi kubi kangakanani futhi amakhambi adingeka ukulawula izimpawu, anciphise ubungozi bezinkinga.

Yize ukusetshenziswa kwe-DDT kwavinjelwa eBrazil ngo-2009, lesi sibulala-zinambuzane sisasetshenziswa ukulwa nomalaleveva e-Asia nase-Afrika ngoba lezi yizindawo lapho kuhlala khona izifo zikamalaleveva, okunzima ukuzilawula. I-DDT nayo ivinjelwe e-United States ngoba kutholakale ukuthi ingumkhiqizo onobuthi ongahlala emhlabathini iminyaka engaphezu kwengu-20, ungcolisa imvelo.

I-DDT ifafazwa ezindongeni nasesilingini ngaphakathi nangaphandle kwezindlu futhi noma isiphi isinambuzane esihlangana nayo siyafa ngokushesha futhi kufanele sishiswe ukuze singangeniswa ezinye izilwane ezinkulu ezingafa futhi ngenxa yobuthi.

Izimpawu ze-DDT ushevu wokubulala izinambuzane

Ekuqaleni i-DDT ithinta uhlelo lokuphefumula nesikhumba, kepha ngemithamo ephezulu ingathinta uhlelo lwe-peripheral nervous futhi ibangele ubuthi besibindi nezinso. Izimpawu zokuqala ze-DDT ushevu wokubulala izinambuzane zifaka:

• Ikhanda;
• Ubomvu emehlweni;
• Isikhumba esilumayo;
• Amachashaza emzimbeni;
• Ukugula kwasolwandle;
• Uhudo;
• Ukopha emakhaleni kanye
• Umphimbo obuhlungu.

Ngemuva kwezinyanga kungcolisiwe, isibulala-zinambuzane i-DDT sisengashiya izimpawu ezinjenge:

• Isifuba Somoya;
• Ubuhlungu obuhlangene;
• Ubuntofontofo ezifundeni zomzimba obuthinte isibulala-zinambuzane;
• Ukuthuthumela;
• Ukudlikizela;
• Izinkinga zezinso.

Ngaphezu kwalokho, ukuxhumana ne-DDT kuphazamisa ukukhiqizwa kwe-estrogen, kunciphisa ukuzala futhi kwandise ubungozi besifo sikashukela sohlobo 2 kanye namathuba omdlavuza webele, wesibindi nowe-thyroid.

Ukuchayeka ku-DDT ngesikhathi sokukhulelwa kwandisa ubungozi bokukhulelwa kwesisu kanye nokubambezeleka kokukhula kwengane ngoba into idlula nge-placenta iye enganeni futhi ibuye ibe sebisini lwebele.

Ungayelapha kanjani i-DDT ushevu

Izindlela zokwelapha ezingasetshenziswa ziyehluka ngoba kuya ngokuthi umuntu wavezwa kanjani kumuthi wokubulala izinambuzane. Ngenkathi abanye abantu behlangabezana nezimpawu ezihlobene nokungezwani komzimba kuphela njengokulunywa nokubomvu emehlweni nasesikhunjeni, okungalawulwa ngamakhambi alwa nokwaliwa, abanye bangathola izimpawu ezinzima kakhulu zokuphefumula, nesifuba somoya. Kulokhu, amakhambi wokulawulwa kwesifuba somoya akhonjisiwe. Labo asebevele bavezwa isibulala-zinambuzane bavame ukuzwa ubuhlungu emisipheni nasemalungeni angaqedwa ngokuqeda izinhlungu.

Ngokuya ngohlobo lwenkinga, ukwelashwa kungahlala izinyanga, iminyaka noma kungadinga ukwelashwa impilo yonke.

Nawa amanye amasu emvelo okugcina omiyane bengekho:

• Isibulala-zinambuzane semvelo esilwa nodenga
• Ukuxoshwa okwenziwe ekhaya kugcina umiyane kude neDengue, iZika neChikungunya
• Thola izinto ezintathu ezixosha imvelo ukugwema omiyane
