Mwa kuyesa, tawona kuti nthawi yayitali yotentha kapena yokhazikika ya madzi ampopi imatha kusintha ma nitrate kukhala nitrites, zomwe maphunziro ena amati ndi carcinogenic.
Mwachitsanzo, mabowo amakambitsirana mpaka 20 nthawi zambiri kuchuluka kwa nitrite mpaka 2.1 μg / l, kupitirira muyezo ndi 0,1 μg / l. Pambuyo pa ma rebiils a Rebiils, milingo ya nitrite idakwera kasanu mpaka 3.53 μg / l. Ngakhale izi zikuwoneka kuti ndizowopsa, zili pansi pamlingo wa nitrite zomwe zimapezeka m'masiku onse ngati ham, zomwe zimatha kukhalapo mpaka 30,000 μg / kg.
M'malo mwake, ngakhale madzi owiritsa nthawi 40 ali ndi nitrites osaposa 3% a kudya tsiku lililonse omwe ali ndi chidwi ndi omwe ali ndi luso la Favo / yemwe katswiri wazolowera kothandizira zakudya (Jecfa). Ntchito zambiri zamabanja ambiri zimakhala ndi kuchuluka kwa 700 ml mpaka 2 l, ndikupangitsa kuti munthu asandukenso madzi okwanira pafupipafupi kuti athe kuyambitsa chiopsezo.
2. Kodi pali gawo pansi pa ketulo langa limakhala ndi ngozi yathanzi?
M'madera okhala ndi madzi olimba, olemera mu calcium ndi magnesium, otentha obwereza amatha kuyambitsa kulimbitsa thupi. Ngakhale izi zitha kuwoneka kuti ndipewe kusalankhula, sizibweretsa zoopsa zazikulu zaumoyo.
Ngakhale mutamwa malita 2 a madzi osindikizidwa kwambiri tsiku lililonse, kudya calcium akadali otsika kwambiri kuposa kapu imodzi ya mkaka.
Wokhawo?
Kukoma sikungakhale kokwanira.
3. Kodi ndikufuna ketulo ndi chinthu cholekana?
Madzi opindika m'matauni ambiri amakhala ndi kachilombo ka chlorine kuti awonetsetse kuti apulumuke kunyumba kwanu. Kutsalira chlorine kumayendetsedwa kuti zikhale pamwamba pa 0.05 mg / l pa mpopi.
Kununkhira kwa chlorine komwe mungazindikire kumachokera ku chlorine yotsalira iyi, yomwe imasiyanasiyana malinga ndi mtunda wanu kuchokera ku malo othandizira madzi. Madzi owiritsa bomba ndi chivundikiro kwa mphindi zochepa chimalola chlorine kuti zitheke.
Ma kerch agulitsidwa ngati kuti ali ndi 'ntchito ' ntchito, yomwe imangofikitsa nthawi yowiritsa, yopereka mphamvu pa makeke. Zachidziwikire, ndizolimbikitsa kwambiri pamlingo wina, kupereka mtengo.
4. Kodi ndimasankha bwanji kukula kwa ketulo?
Kuyenda:
Zoyendayenda ndi ma carties pakati pa 350 ml ndi 650 ml ndizabwino. Izi zimawapangitsa kukhala otchuka pamaulendo ndi tchuthi.
HCK-01 350mL yoyendayenda
FZB-CP01 650ml Tritete
Pogwiritsa ntchito kunyumba: kwa mabanja, 1.5 l mpaka 2 l ndi chisankho chothandiza. Izi zimatha mwachangu wiritsani madzi okwanira aliyense, ndikuwapangitsa kukhala angwiro kuti banja lizigwiritsa ntchito.
W181 ketulo yamagetsi
W20 ketulo yamagetsi
5. Chifukwa chiyani ma kengelo athu amasankhira ma kenger otani?
Pa fakitale yathu, timapanga ma keker ndi zinthu zokumana ndi zinthu zosiyanasiyana, ndikuonetsetsa chitetezo, kutheka, ndi kulimba. Kaya mukuyang'ana ma kemoni oyendayenda kapena zosankha zazikulu zabanja, timapereka njira zochizira kuti mufanane ndi zomwe mumakonda.
