Semelo sa Tlhokomelo ea Boleng ba Metsi le Litlhoko tsa Taolo ea Chlorine Vietnam
Jwalo ka naha e ntseng e hola ka potlako diindastering le ditoropong tse ka Borwa-botjhabela ba Asia, Vietnam e tobane le dikgatello tse pedi tsamaisong ya mehlodi ya metsi. Dipalopalo di bontsha hore hoo e ka bang 60% ya metsi a ka tlase ho lefatshe le 40% ya metsi a ka hodima lefatshe Vietnam a silafetse ka tekanyo e fapaneng, mme tshilafatso ya dikokwana-hloko le dikhemikhale e le yona ntho ya bohlokwa. Ditsamaisong tsa phepelo ya metsi, chlorine e setseng – e le karolo e setseng ya chlorine e sebetsang ho tloha ho tshwaetsong ya dikokwana-hloko – e bapala karolo ya bohlokwa ho netefatseng polokeho ya metsi. Klorine e sa lekaneng e setseng e hloleha ho fedisa dikokwana-hloko ka dinako tsohle diphaepheng, athe maemo a feteletseng a ka hlahisa dihlahiswa tse bakang ho tshwaetswa ke kankere. WHO e kgothaletsa ho boloka maemo a chlorine a setseng pakeng tsa 0.2-0.5mg/L metsing a nowang, ha maemo a QCVN 01:2009/BYT a Vietnam a hloka bonyane 0.3mg/L mafelong a diphaephe.
Meralo ea motheo ea metsi Vietnam e bontša ho se lekane ho hoholo ha litoropo le mahaeng. Libaka tsa litoropo tse kang Hanoi le Ho Chi Minh City li na le litsamaiso tse felletseng tsa phepelo empa li tobane le liphephetso tse tsoang liphaepheng tse tsofetseng le tšilafalo ea bobeli. Hoo e ka bang 25% ea baahi ba mahaeng ba ntse ba haelloa ke phihlello ea metsi a nooang a sireletsehileng, ba itšetlehile haholo-holo ka metsi a sa phekoloang hantle kapa a holim'a metsi. Nts'etsopele ena e sa lekanang e hlahisa litlhoko tse fapaneng tsa mahlale a tlhokomelo ea chlorine - libaka tsa litoropo li hloka litsamaiso tsa inthanete tse nepahetseng haholo, tsa nako ea sebele ha libaka tsa mahaeng li beha pele ho boloka litšenyehelo le boiketlo ba ts'ebetso.
