Lintlha tse potlakileng mabapi le lihloela tsa metsi: li fokotsa monko, li tlosa litatso tse monate, 'me li sebetsana le mathata a litšila. Empa lebaka le ka sehloohong leo ka lona batho ba khethang metsi a hloekisitsoeng ke bophelo bo botle. Meaho ea motheo ea metsi United States haufinyane e fumane lintlha tsa D ho tsoa ho American Society of Civil Engineers. Mokhatlo o qotsitse libaka tsa metsi a silafetseng le metsi a senyehileng e le lintho tse tšoenyang haholo.

Ka litšepe tse boima tse kang loto le lik'hemik'hale tse kang chlorine tse lulang li le teng phepelong ea rona ea metsi, hoa thabisa ho utloa hore metsi a hloekisitsoeng a ka ntlafatsa bophelo ba rona mme a re sireletsa litabeng tse tebileng tsa bophelo bo botle. Empa joang?

Fokotsa Kotsi ea Kankere

Metsi a mangata a pompo a tšeloa ka lik'hemik'hale ho tlosa likokoana-hloko. Lik'hemik'hale tse kang chlorine le chloramine li sebetsa hantle ho ntša likokoana-hloko, empa li ka baka mathata a bophelo ka botsona. Chlorine e ka sebelisana le metsoako ea lintho tse phelang phepelong ea metsi ho etsa lihlahisoa tse bolaeang likokoana-hloko. Li-Trihalomethanes (THMs) ke mofuta o mong oa lihlahisoa mme li tsejoa ka ho eketsa kotsi ea hau ea mofets'e mme e ka baka mathata a ho ba le bana. Chlorine le chloramine li amahanngoa le kotsi e eketsehileng ea ho tšoaroa ke kankere ea senya le ea rectum.

Melemo ea bophelo bo botle ba metsi a hloekisitsoeng e kenyelletsa kotsi e fokotsehileng ea mofets'e hobane feela o sa pepesehetse lik'hemik'hale tsena tse kotsi. Metsi a hloekisitsoeng a hloekile, a hloekile, 'me a sireletsehile ho nooa.

Sireletsa Mafung

Ha liphaephe li lutla, li senya kapa li pshatla likokoana-hloko tse kotsi tse kang E. coli baktheria li ka kena metsing a hao a nooang ho tsoa mobung o potolohileng le mehloli ea metsi. Likokoana-hloko tse tsamaeang le metsi li ka baka mathata ho tloha ka mpeng ho isa ho lefu la Legionnaires.

Mochine o hloekisang metsi o nang le tšireletso ea lebone la ultraviolet (kapa UV) o tla senya matla a likokoana-hloko kapa likokoana-hloko tsa ho ikatisa. Metsi a hloekisitsoeng a ka u sireletsa uena le ba lelapa la hao khahlanong le mefuta e mengata ea likokoana-hloko le mafu a bakoang ke lintho tse phelang.

Nolofatsa Letlalo le Moriri oa Hao

Ho hlapa ka metsi a chlorine ho ka etsa hore letlalo la hao le omelle, le petsole, le be khubelu le ho teneha. Metsi a chlorinated le ona a ka thethefatsa moriri oa hau. Matšoao ana kaofela a tloaelehile ho batho ba sesang ba qetang nako matamong a sebaka seo, empa bakeng sa ho hlatsoa ka tlung ea hau, ha ho hlokahale hore u halefise letlalo le moriri oa hau ka chlorine.

Lisebelisoa tsa ho hloekisa metsi ka tlung eohle li sefa litšila tse kang chlorine le chloramine ha li kena ka tlung ea hau. Metsi a hau ha a na lik'hemik'hale tse bohale ho sa tsotellehe hore na a tsoa ka sinking ea kichineng kapa ka shaoareng. Haeba u hlapa ka metsing a hloekisitsoeng ka likhoeli tse 'maloa u ka hlokomela hore moriri oa hau o mahlahahlaha le letlalo la hao le bonolo ebile le le bonolo haholoanyane.

Hloekisa Lijo Tsa Hao

Ntho e bonolo joaloka ho hlatsoa meroho ea hau ka sekoting pele u lokisa salate e ka tšoaetsa lijo tsa hau tsa motšehare ka chlorine le lik'hemik'hale tse ling tse bohale. Ha nako e ntse e ea ho ja chlorine lijong tsa hau ho ka eketsa kotsi ea ho tšoaroa ke mofetše oa matsoele - Scientific American e supa hore basali ba nang le mofetše oa matsoele ba na le 50-60% e eketsehileng ea chlorine ka har'a matsoele a bona ha ba bapisoa le basali ba se nang mofetše. Metsi a tlhotliloeng a u sireletsa likotsing tsa ho noa chlorine lijong tsa hau.

Ka ho lokisa lijo tsa hau ka metsi a tlhotliloeng a nang le lik'hemik'hale le a sa silafalang, u boetse u lokisa lijo tse monate, tse monate. Chlorine e ka ama tatso le 'mala oa lijo tse ling, haholo lihlahisoa tse kang pasta le bohobe.
