Mfundo zachangu zokhudza zosefera madzi: zimachepetsa fungo, zimachotsa kukoma kosangalatsa, komanso zimathetsa mavuto a matope. Koma chifukwa chachikulu chomwe anthu amasankhira madzi osefedwa ndi thanzi. Posachedwapa, zomangamanga zamadzi ku United States zalandira D rating kuchokera ku American Society of Civil Engineers. Bungweli linatchula malo odetsedwa amadzi ndi madzi otayidwa ngati nkhawa yaikulu.

Popeza zitsulo zolemera monga lead ndi mankhwala monga chlorine zimapezeka nthawi zonse m'madzi athu, timasangalala kumva kuti madzi osefedwa angathandize thanzi lathu ndikutiteteza ku mavuto aakulu azaumoyo. Koma bwanji?

Kuchepetsa Kuopsa kwa Khansa

Madzi ambiri apampopi amathiridwa mankhwala kuti achotse tizilombo toyambitsa matenda. Mankhwala monga chlorine ndi chloramines ndi othandiza pochotsa tizilombo toyambitsa matenda, koma amatha kuyambitsa mavuto azaumoyo okha. Chlorine imatha kuyanjana ndi mankhwala achilengedwe omwe ali m'madzi kuti apange mankhwala ophera tizilombo toyambitsa matenda. Trihalomethanes (THMs) ndi mtundu umodzi wa mankhwala ophera tizilombo ndipo amadziwika kuti amawonjezera chiopsezo chanu cha khansa komanso angayambitse mavuto obereka. Chlorine ndi chloramines zimagwirizanitsidwa ndi chiopsezo chowonjezeka cha khansa ya chikhodzodzo ndi rectal.

Ubwino wa madzi osefedwa pa thanzi ndi monga kuchepetsa chiopsezo cha khansa chifukwa choti simukumana ndi mankhwala owopsa awa. Madzi osefedwa ndi oyera, oyera, komanso otetezeka kumwa.

Tetezani ku Matenda

Pamene mapaipi akutuluka, amawononga kapena kuswa tizilombo toyambitsa matenda monga mabakiteriya a E. coli amatha kulowa m'madzi anu akumwa kuchokera m'nthaka ndi m'madzi ozungulira. Tizilombo toyambitsa matenda tomwe timafalikira m'madzi tingayambitse mavuto kuyambira kupweteka pang'ono m'mimba mpaka matenda a Legionnaires.

Dongosolo losefera madzi lokhala ndi chitetezo cha kuwala kwa ultraviolet (kapena UV) lidzawononga mphamvu ya tizilombo toyambitsa matenda kapena tizilombo toyambitsa matenda yobereka. Madzi osefedwa amatha kukutetezani inu ndi banja lanu ku mavairasi ndi matenda osiyanasiyana oyambitsidwa ndi zinthu zachilengedwe.

Chinyezitsani Khungu Lanu ndi Tsitsi Lanu

Kusamba m'madzi okhala ndi chlorine kungayambitse khungu lanu kuuma, kusweka, kufiira, komanso kukwiya. Madzi okhala ndi chlorine amathanso kupangitsa tsitsi lanu kukhala losasangalatsa. Zizindikiro zonsezi ndizofala kwa osambira omwe amakhala nthawi yayitali m'madziwe akumaloko, koma pa shawa m'nyumba mwanu, palibe chifukwa chokwiyitsa khungu lanu ndi tsitsi lanu ndi chlorine.

Makina osefera madzi a m'nyumba yonse amasefera zinthu zodetsa monga chlorine ndi chloramines akamalowa m'nyumba mwanu. Madzi anu alibe mankhwala oopsa kaya akuchokera ku sinki yanu yakukhitchini kapena ku shawa. Ngati musamba m'madzi osefedwa kwa miyezi ingapo mungazindikire kuti tsitsi lanu ndi lowala bwino ndipo khungu lanu ndi lofewa komanso lofewa.

Tsukani Chakudya Chanu

Chinthu chosavuta monga kutsuka masamba anu obiriwira mu sinki musanakonze saladi chingawononge chakudya chanu chamasana ndi chlorine ndi mankhwala ena oopsa. Pakapita nthawi kumwa chlorine mu chakudya chanu kungakulitse chiopsezo chanu chokhala ndi khansa ya m'mawere — Scientific American ikunena kuti akazi omwe ali ndi khansa ya m'mawere ali ndi 50-60% ya chlorine m'mafupa awo poyerekeza ndi akazi omwe alibe khansa. Madzi osefedwa amakutetezani ku zoopsa zomwa chlorine mu chakudya chanu.

Mukakonza chakudya chanu ndi madzi osefedwa opanda mankhwala komanso odetsedwa, mumakonzanso chakudya chokoma komanso chabwino. Chlorine imatha kusokoneza kukoma ndi mtundu wa zakudya zina, makamaka zinthu monga pasitala ndi buledi.
