Zowona zachangu pa zosefera zamadzi: zimachepetsa fungo, zimachotsa zokonda zoseketsa, ndikusamalira zovuta. Koma chifukwa chachikulu chimene anthu amasankhira madzi osefedwa ndi thanzi. Malo opangira madzi ku United States posachedwapa adalandira mlingo wa D kuchokera ku American Society of Civil Engineers. Bungweli lidatchula mabwalo amadzi oipitsidwa komanso kutha kwa madzi ngati zinthu zomwe zimadetsa nkhawa kwambiri.

Ndi zitsulo zolemera monga mtovu ndi mankhwala monga klorini omwe amakhalapo nthawi zonse m'madzi athu, zimakhala zotsitsimula kumva kuti madzi osefedwa amatha kukhala ndi thanzi labwino komanso kutiteteza ku mavuto aakulu azaumoyo. Koma bwanji?

Chepetsani Kuopsa kwa Khansa

Madzi ambiri apampopi amathiridwa ndi mankhwala kuti achotse tizilombo toyambitsa matenda. Mankhwala monga klorini ndi chloramines amagwira ntchito pochotsa tizilombo tating'onoting'ono, koma amatha kuyambitsa mavuto paokha. Chlorine imatha kuyanjana ndi zinthu zachilengedwe m'madzi kuti apange mankhwala ophera tizilombo toyambitsa matenda. Trihalomethanes (THMs) ndi imodzi mwazinthu zopangidwa mwachilengedwe ndipo amadziwika kuti amawonjezera chiwopsezo cha khansa komanso zomwe zingayambitse kubereka. Chlorine ndi ma chloramines amalumikizidwa ndi chiopsezo chowonjezereka chokhala ndi khansa ya chikhodzodzo ndi rectum.

Ubwino wamadzi osefedwa umaphatikizapo kuchepetsa chiopsezo cha khansa chifukwa chakuti simukukhudzidwa ndi mankhwalawa. Madzi osefa ndi oyera, aukhondo, ndi abwino kumwa.

Tetezani ku Matenda

Pamene mapaipi atayikira, amawononga kapena kuswa tizilombo toyambitsa matenda monga mabakiteriya a E. coli amatha kulowa m'madzi anu akumwa kuchokera ku dothi ndi madzi ozungulira. Tizilombo toyambitsa matenda timene timakhala m'madzi titha kuyambitsa mavuto kuyambira kukomoka pang'ono m'mimba mpaka matenda a Legionnaires.

Makina osefera m'madzi okhala ndi chitetezo cha kuwala kwa ultraviolet (kapena UV) amawononga mphamvu ya tizilombo toyambitsa matenda kapena tizilombo toyambitsa matenda. Madzi osefedwa amatha kukutetezani inu ndi banja lanu ku mitundu yosiyanasiyana ya ma virus ndi matenda obwera chifukwa cha zinthu zachilengedwe.

Limbikitsani Khungu Lanu ndi Tsitsi

Kusamba m'madzi a chlorini kungapangitse khungu lanu kukhala louma, losweka, lofiira, komanso lopsa mtima. Madzi a klorini amathanso kusokoneza tsitsi lanu. Zizindikiro zonsezi ndizofala ndi osambira omwe amathera nthawi m'madziwe am'deralo, koma posamba m'nyumba mwanu, palibe chifukwa chokwiyitsa khungu ndi tsitsi lanu ndi chlorine.

Makina osefera amadzi a m'nyumba yonse amasefa zonyansa monga chlorine ndi ma chloramines zikamalowa mnyumba mwanu. Madzi anu alibe mankhwala owopsa kaya akutuluka mu sinki yanu yakukhitchini kapena mu shawa. Ngati musamba m'madzi osefedwa kwa miyezi ingapo mungaone kuti tsitsi lanu limakhala lamphamvu kwambiri ndipo khungu lanu ndi lofewa komanso losalala.

Yeretsani Chakudya Chanu

Chinachake chophweka monga kutsuka masamba anu mu sinki musanakonzekere saladi akhoza kupatsira nkhomaliro yanu ndi chlorine ndi mankhwala ena ovuta. Popita nthawi, kumwa chlorine m'zakudya zanu kumatha kukulitsa chiwopsezo chanu chokhala ndi khansa ya m'mawere - Scientific American ikunena kuti amayi omwe ali ndi khansa ya m'mawere amakhala ndi 50-60% zowonjezera za chlorine m'minyewa yawo poyerekeza ndi amayi omwe alibe khansa. Madzi osefedwa amakutetezani kuopsa kolowetsa chlorine muzakudya zanu.

Pokonza chakudya chanu ndi madzi osefedwa ndi mankhwala komanso opanda zodetsa, mumapanganso zakudya zokometsera komanso zabwinoko. Chlorine imatha kukhudza kukoma ndi mtundu wa zakudya zina, makamaka zinthu monga pasitala ndi mkate.
