Ukuqhagamshelana ne-DDT Insecticide kunokubangela umhlaza kunye nokungabikho

Umxholo

• Kufuneka wenze ntoni xa ungcoliseka ukrokreleka
• Iimpawu zetyhefu yokubulala izinambuzane ze-DDT
• Ungayinyanga njani ityhefu ye-DDT
• Nazi izicwangciso zendalo zokugcina iingcongconi kude:

Isibulala-zinambuzane se-DDT somelele kwaye siyasebenza ngokuchasene nengcongconi ye-malaria, kodwa inokubangela nokonakalisa impilo, xa idibana nolusu okanye iphefumlelwe ngumoya, ngexesha lokutshiza kwaye ke abo bahlala kwiindawo apho isifo seengcongconi sihlala khona kwaye Esi sibulali zinambuzane sisetyenzisiweyo kufuneka sikuphephe ukuhlala ngaphakathi endlwini ngosuku lokunyangwa kwendlu, kwaye kuthintele ukubamba iindonga ezihlala zimhlophe ngenxa yetyhefu.

Kufuneka wenze ntoni xa ungcoliseka ukrokreleka

Kwimeko yokungcola okukrokrelwayo, kuya kufuneka ugqirha ubonise okwenzekileyo kunye neempawu onazo. Ugqirha unokuyalela ukuba kuvavanywe ukuba bekukho ukungcola, ukuba bunzima kangakanani kwaye amayeza afunekayo ukulawula iimpawu, ukunciphisa umngcipheko weengxaki.

Nangona ukusetyenziswa kwe-DDT kwavalwa eBrazil ngo-2009, esi sibulali zinambuzane sisasetyenziswa ukulwa imalariya e-Asiya nase-Afrika kuba le yimimandla apho kuhlala kukho isifo seengcongconi, ekunzima ukusilawula. I-DDT yayivaliwe nase-United States kuba kwafumaniseka ukuba iyimveliso enetyhefu enokuhlala emhlabeni ngaphezulu kweminyaka engama-20, ingcolisa indalo.

I-DDT ifafazwa ezindongeni nakwisilingi ngaphakathi nangaphandle ezindlwini kwaye nasiphi na isinambuzane esidibene nayo siyafa kwangoko kwaye kufuneka sitshiswe ukuze singangenisi ezinye izilwanyana ezinkulu ezinokuthi nazo zibulawe yityhefu.

Iimpawu zetyhefu yokubulala izinambuzane ze-DDT

Ekuqaleni i-DDT ichaphazela inkqubo yokuphefumla kunye nolusu, kodwa kwiidosi eziphezulu inokuchaphazela inkqubo ye-peripheral luvo kwaye ibangele ityhefu yesibindi kunye nezintso. Iimpawu zokuqala zetyhefu yokubulala izinambuzane ye-DDT zibandakanya:

• Intloko ebuhlungu;
• Ubomvu emehlweni;
• Ukurhawuzelela ulusu;
• Amabala emzimbeni;
• Ukugula elwandle;
• Urhudo;
• Ukopha kwimpumlo kunye
• Umqala obuhkungu.

Emva kweenyanga zongcoliseko, iyeza lokubulala izitshabalalisi i-DDT lisenokushiya iimpawu ezinje:

• Isifuba;
• Intlungu edibeneyo;
• Ubungqindilili kwimimandla yomzimba enxibelelana nesibulali zinambuzane;
• Ukungcangcazela;
• Ukuxhuzula;
• Iingxaki zezintso.

Ukongeza, ukunxibelelana ne-DDT kuphazamisa ukuveliswa kwe-estrogen, ukwehla kokuchuma kunye nokwandisa umngcipheko wohlobo lweswekile yesi-2 kunye nokubakho komhlaza webele, wesibindi kunye nomhlaza wedlala lengqula.

Ukubonakaliswa kwi-DDT ngexesha lokukhulelwa kwandisa umngcipheko wokuphuma kwesisu kunye nokulibaziseka ukukhula komntwana kuba into leyo idlula kwi-placenta iye emntwaneni kwaye ikwakhona kubisi lwebele.

Ungayinyanga njani ityhefu ye-DDT

Unyango olunokusetyenziswa luyahluka kuba luxhomekeke kwindlela umntu avele ngayo kwisibulali zinambuzane. Ngelixa abanye abantu befumana kuphela iimpawu ezinxulumene nokungabikho komzimba ezinje ngokurhawuzelela nokubomvu emehlweni naseluswini, ezinokulawulwa ngamayeza okulwa nokwaliwa, abanye banokufumana iimpawu ezibi kakhulu zokuphefumla kancinci, nesifuba. Kule meko, amayeza olawulo lwesifuba abonakalisiwe. Abo sele bechaphazelekile kwizinambuzane ezinokubulala iintlungu banokuhlala befumana iintlungu kwimisipha kunye namalungu anokuthomalalisa iintlungu.

Kuxhomekeka kuhlobo lwengxaki, unyango lunokuhlala iinyanga, iminyaka okanye kungafuneka lunyangwe ubomi bakho bonke.

Nazi izicwangciso zendalo zokugcina iingcongconi kude:

• Inambuzane yendalo ngokuchasene neDengue
• Izinto zokugxotha ekhaya zigcina iingcongconi kude neDengue, iZika kunye neChikungunya
• Fumana izinto ezi-3 eziGxotha iNdalo ukuze ugweme iingcongconi
