Madzi a Raw ali ndi mafani omwe akukula ku United States, makamaka ku California. Koma kodi ilidi ndi thanzi labwino monga momwe otsatira ake amakhulupirira?
Pali zochitika kulikonse masiku ano - kuphatikiza pazakudya (zathanzi). Gulu latsopano lochokera ku USA ladzipatulira kumadzi osaphika. Ziyenera kukhala zabwino kwambiri komanso zathanzi kwa thupi lathu. Koma kodi zimenezo n’zoona? Kodi tilowe nawo mchitidwewu ndipo ndi wabwinodi kwa ife? Tinayang'anitsitsa mchitidwewu.
Madzi osaphika ndi chiyani?
Mawu akuti “madzi aiwisi” amabisa madzi kuchokera ku zinthu zachilengedwe zomwe samasefedwanso kapena kuyeretsedwa. Ilinso ndi tsiku lotha ntchito ndipo imasanduka yobiriwira ngati yasiyidwa motalika kwambiri. Komabe, ichi chiyenera kukhala chizindikiro cha kutsitsimuka kwake kwapadera.
Mosiyana ndi madzi a pampopi, madzi aiwisi ayenera kukhala ndi mabakiteriya onse athanzi komanso opanda zinthu zoopsa. Zotsatira za tizilombo toyambitsa matenda zomwe zimati zili m'madzi a Raw ndi zazikulu: ziyenera kuonetsetsa kuti khungu labwino, kupanga ziphuphu ndi makwinya kutha ndikupangitsa tsitsi kukhala lokongola kwambiri. Misomali ndi mfundo ziyeneranso kupindula ndi madzi.
Wothandizira "Live Spring Water" makamaka wakhala wothandiza kwambiri polimbikitsa madzi ake osatulutsidwa kuchokera ku gwero. Zogulitsa, zomwe malita 7.5 zimapezeka kwa ma euro ochepera 14, nthawi zambiri sizipezeka m'masitolo akuluakulu aku America. Malo ogulitsa a Live Spring Water: Tikufuna kuti madzi anu akhale abwino kwambiri. Kukatentha kwambiri ndikusungidwa padzuwa, kumasanduka obiriwira msanga. Izi sizichitika ndi madzi abwinobwino ochokera ku supermarket chifukwa siabwino ngati madzi osaphika.
Kodi Njira ya Madzi Owiritsa Ndi Yathanzi?
Mpaka pano palibe umboni wa sayansi wosonyeza kuti madzi osaphika ali ndi zotsatira zabwino pa thanzi lathu. Ngakhale otsatira a kayendedwe ka madzi kasupe amatsimikiza za zotsatira za madzi, izi sizinatsimikizidwebe. M'malo mwake, akatswiri amalangizanso kuti asamwe madzi oyera a masika.
Ndicho chifukwa chake akatswiri amachenjeza za kusayang'aniridwa moyenerera kwa madzi osaphika
Tili ndi Dr. Ingrid Chorus, mkulu wa dipatimenti ya kumwa ndi kusamba madzi dziwe ukhondo pa Federal Environment Agency. Iye anatiuza kuti: “Sindikanamwa madzi amene amalengeza kuti ali ndi ‘mabakiteriya athanzi’. Sizikudziwika kuti amayendetsedwa bwino bwanji ndipo pali zifukwa zomveka zomwe madzi akumwa amawunikidwa mosamala kwambiri komanso chifukwa chake athu.
Kumbali imodzi, madzi amathanso kukhala ndi ma virus kapena magawo osatha a tizilombo toyambitsa matenda kuchokera ku nyama zomwe zimatha kugonjetsedwa ndi chilengedwe. Kuno ngakhale kudya pang'ono kachilombo kungayambitse kutsekula m'mimba kwambiri. "Pachifukwachi, oyendayenda, mwachitsanzo, amachenjezedwa kuti asamwe madzi a m'mitsinje - ngakhale m'nkhalango kapena m'mapiri okwera opanda midzi kapena ulimi," akufotokoza Dr.
Kumbali ina, munthu sangadziŵe ndendende mmene anthu ena anaipitsira madziwo. “Komanso, munthu asaiwale kuti izi zimachokera ku USA, komwe madzi nthawi zambiri amakhala osakanikirana ndi chlorine ndipo anthu ambiri amawona izi kukhala zosasangalatsa. Izi sizili choncho ku Germany. Chlorine imagwiritsidwa ntchito pano pokhapokha ngati madzi akudutsa pamwamba pa madzi. Ndalama zomwe zimagwiritsidwa ntchito zikadali zazing'ono kwambiri kotero kuti palibenso kuchuluka kulikonse pampopi,” akutero Dr. Ingrid Chorus.
Zodabwitsa ndizakuti, tsamba la Live Water limati madzi awo amachokera ku kasupe wa Opal ku Oregon ndipo amayesedwa chaka chilichonse. Palibe kuipitsidwa komwe kunapezeka pamayesowa. Dokotala ndi mtolankhani wazachipatala Sarang Koushik adayankhapo kale pa ABC News ndipo adafotokoza kuti madziwo sanayesedwe mwalamulo.
dr Ingrid Chorus akunena kuti ngati madziwo ayesedwa ndi kutsimikiziridwa kuti amachokera ku akasupe akuya otetezedwa, angafanane ndi madzi a m’mabotolo ochokera ku Germany, omwenso ndi madzi akasupe osayeretsedwa. Komabe, sayenera kukhala ndi mabakiteriya ambiri ndipo sayenera kukhala obiriwira - ndipo sangakhale "amoyo".
Kodi tingamwe madzi athu akumwa osasefa?
Ku Germany, 99 peresenti ya milingo yamadzi akumwa imakwaniritsa zofunikira za Dongosolo la Madzi Akumwa. Mabakiteriya amatha kuzindikirika mu gawo limodzi mwa magawo khumi a miyeso. Komabe, ndende yawo nthawi zambiri imakhala yotsika kwambiri kotero kuti palibe chowopsa ku thanzi. Malire a mabakiteriya amayikidwa dala kuti akhale otsika kwambiri, kotero kuti kupitilira iwo sikungakhale ndi zotsatira za thanzi. Kuphatikiza apo, ziwongola dzanja zochulukira zimayesedwa kwakanthawi ndipo sizingadziwikenso pa cheke chotsatira.
Kuphatikiza apo, madzi athu akumwa amasefedwa m'madzi - mwaukadaulo kwambiri komanso kuyang'anira bwino momwe ntchitoyi ikuyendera - kapena, ngati ndi madzi apansi kuchokera m'nthaka zakuya, kudzera m'nthaka - yomwe, mwa njira, ndi fyuluta yabwino kwambiri. .
Nthaŵi zambiri madzi amene amatuluka pampopi safunikira kusefedwa. Kugwiritsa ntchito zosefera zamadzi sikofunikira, makamaka m'mizinda ikuluikulu komwe kuli kotsimikizika komwe madzi akumwa amachokera. Zimangowoneka mosiyana pang'ono ngati ndinu mlendo kumadera akumidzi ndipo simukudziwa kumene madzi akumwa amachokera komanso momwe amawayang'anira.
"Tikukayikira pankhaniyi ndikudabwa ngati kugwiritsa ntchito zosefera zamadzi kumatha kubweretsa zinthu zina zowonjezera kapena ngati mabakiteriya adzakula mu chipangizochi," akutero Dr. Ingrid Chorus. Mwa njira, sitiyenera kuopa matepi owerengeka. “Laimu alibe vuto,” akutero katswiriyo.
Mkhalidwewu ndi wosiyana pang'ono, komabe, ngati mapaipi a m'nyumba sali bwino komanso / kapena madzi amasunthika m'mipope kwa nthawi yayitali pokwera. Pankhaniyi, mwachitsanzo, kutsogolera kungalowe m'madzi.
Koma ngati madziwo atuluka abwino ndi ozizira pampopi, mukhoza kumwa. Ngati mulibenso pampopi, madziwo alibe nthawi yochotsa zowononga pampopi. Ichi ndichifukwa chake lamulo lofunikira kwambiri ndikuti madzi amakhala abwino, "akutero Chorus.
Kodi tikuphunzira chiyani? Simukuyenera kutsatira njira iliyonse ndipo ku Germany mutha kumwa madzi omwe amachokera pampopi ndi mtendere wamalingaliro. Tikhoza kusiya kusefa kwa madzi.
