Kule mihla, izinto zokuthambisa ziye zaba zizinto eziyimfuneko ebomini bethu. Nangona kunjalo, kwiminyaka yakutshanje, iziganeko zokhuseleko lwezinto zokuthambisa ziye zenzeka rhoqo. Ngenxa yoko, abantu banikela ingqalelo ngakumbi kukhuseleko lwezinto zokuthambisa. Okwangoku, iintlobo zezinto zokuthambisa ezikwimarike ziye zanda, zinezithako ezahlukeneyo nezintsonkothileyo. Ungawugweba njani ukhuseleko lwezinto zokuthambisa?
Okwangoku, ukongeza ekusebenziseni izixhobo zovavanyo zobungcali ukuchonga ukhuseleko lwezithambiso, singakwazi nobuchule kwiingcebiso ezininzi zokuchonga izinto ezilungileyo nezingalunganga zezithambiso, ezibonakala kakhulu kwezi zinto zilandelayo:
Okokuqala, jonga ilogo ye-QS kunye nezatifikethi ezintathu (ilayisenisi yemveliso, ilayisenisi yezempilo kunye nemigangatho yokusebenza). Ukuba kukho ilogo ye-QS kunye nezatifikethi ezintathu kwiphakheji, oko kubonisa ukuba izithambiso ziveliswa ngumvelisi oqhelekileyo oneziqinisekiso zemveliso, ngoko ke unokuqiniseka ukuba ziyasebenza.
Okwesibini, jonga izithako. Xa ukhetha izinto zokuthambisa ezikhuselekileyo, into yokuqala efika engqondweni kukujonga izithako. Ulawulo lokubhala iilebheli zezithambiso luthi zonke izinto zokuthambisa eziveliswayo mazifake iilebheli kuzo zonke izithako ezikwiphakheji yangaphandle okanye kwimiyalelo.
Okwesithathu, sebenzisa impumlo yakho ukuvumba nokuva ivumba leemveliso zokhathalelo lolusu. Ungahlula ukuba livumba lendalo okanye livumba leekhemikhali. Izithambiso ezingafaki zivumba zekhemikhali ziya kwenza abantu bazive bethomalalisiwe kwaye bethomalalisa uxinzelelo. Ukuze bafihle ivumba elingathandekiyo lezithako ezithile zeekhemikhali, ezinye izithambiso ziya kukhetha ukongeza izithambiso zekhemikhali. Ukusebenzisa izithambiso ezineevumba ezininzi zeekhemikhali kuya kubangela ukungezwani nolusu, i-dermatitis okanye i-pigmentation, njl.njl., ngaloo ndlela kwenza ulusu lube lubi ngakumbi nangakumbi.
Okwesine, indlela yokufumanisa ubucwebe besilivere. Ezinye izinto zokuthambisa ezinemiphumo yokususa amabala amhlophe kunye namabala amhlophe ngokubanzi ziqulathe ivithamin C kunye ne-arbutin. Uphawu lwazo oluphambili kukuba zinokuphucula umgangatho wolusu kancinci kancinci. Ezo zinto zokuthambisa ezibizwa ngokuba ziizinto zokuthambisa ezinokususa amabala amhlophe ngokukhawuleza nangokufanelekileyo ziqulethe izinto ezininzi eziyingozi ezifana ne-lead kunye ne-mercury. Izinto zeekhemikhali, ezifana nezinto zokuthambisa ezine-lead kunye ne-mercury ezisetyenziswa ngabathengi ixesha elide, zinokubangela ityhefu engapheliyo emzimbeni. Ke ngoko, ngaphambi kokusebenzisa olu hlobo lwezinto zokuthambisa, qiniseka ukuba ucwilisa inani elincinci leemveliso zokhathalelo lolusu kwizinto zokuthambisa zesilivere kwaye wenze imikrwelo embalwa ephepheni elimhlophe. Ukuba amanqaku ephepha elimhlophe ajika abe ngwevu kwaye abe mnyama, oko kuthetha ukuba izinto zokuthambisa ziqulethe inani elikhulu le-lead kunye ne-mercury kwaye azivumelekanga ngokupheleleyo ukusetyenziswa.
Okwesihlanu, indlela yokuvavanya iphepha lovavanyo lwe-pH. Ekubeni ulusu lomntu lune-asidi encinci, zizimonyo ezibuthathaka kuphela ezinokufezekisa iziphumo zokhathalelo lolusu. Ngaphambi kokusebenzisa, kufuneka ufake inani elincinci lezimonyo kwiphepha lovavanyo lwe-pH. Emva kokuthelekisa itshathi yombala yephepha lovavanyo, ukuba izimonyo zine-alkaline, kuphephe ukuzisebenzisa.
