Murwiyo rwemvura uye utano vanhu ... simba sei ukama uyu?

Munyika tsika, unhu mvura achatongwa maererano rimwe zana uye nokukanganisika parameters. Zvechokwadi, hazvibviri kuramba kuongorora murwiyo mvura nerimwe zviratidzo izvi, kuitira kuti zvakafanira kuti kunwa zvinangwa.

Hatifaniri kufunga kuti mumba yedu yaipiwa nemvura, inova dirtier zvikuru pane zvakasikwa zvinyorwa. Zvechokwadi, asati kupinda muguta mvura Network wakapfuura mumatanho akawanda rokugadzirira uye yokuzvinatsa, somugumisiro chikamu kunwa mvura yacho iri kuunzwa ezvinhu kugutsa utsanana-epidemiological pamutemo zvinodiwa.

The chikuru dambudziko ndechokuti nguva dzose kuwedzera kwete chete inzwi asiwo uwandu zvinhu kuti kusvibisa mvura ine makungwa nenzizi. Kukanganisa mamiriro nemvura yedu yekare mvura mugadziriro, apo kunyange mushure mvura yakanaka kwazvo yakachena zvakare anowana zvimwe mugove yakasviba. Naizvozvo, kuvandudzwa itsva mvura kurapwa gadziriro Akagamuchira kuwedzera kutarisirwa uye nesimba.

Zviremera kuongorora nokukanganisika Zvinoumba mvura uye kugara kuwana nzira kuti tiuye nazvo zvinodiwa sanepidnormami wehurumende. Asi ichi hachisi chete dambudziko kwakabatana mvura yepamusoro. Makemikari anoumba mvura munzizi uye reservoirs, masayendisiti vaiva nechokwadi kuti akanga akasiyana latitudes siyana. Kusiyana chaizvo zvakawanda, nokuti zvinoenderana Kuwanikwa zvicherwa, munyu uye zvimwe soluble zvinhu zvichiitika goko paNyika. Mune dzimwe nzvimbo, mvura ine nekumwisa chicherwa yacho, uye vamwe havana kunyange shoma yakatarwa yavo.

Saka, murwiyo mvura yegungwa - ndiwo muenzaniso wakajeka yebongozozo munyu mumvura, zvicherwa, uye tsvina yacho pasi pemvura nyika. In makungwa akaumba munharaunda zvakanyunguduka chando, mvura ine vashoma chaizvo ichiputswa zvicherwa, kusanganisira calcium magnesium munyu.

Vanhu upise mvura kubva zvinyorwa zvakadai achiumbwa mumuviri anobatsira zvisaririra zvinhu kushaikwa, izvo kunokanganisa utano. Migumisiro yakaipa uye zvichizoita kwakavandudzwa mvura salinity, kunyange zvazvo "mvura zvakaoma" zviri nyore kuti uve Zvakanyanya Kunaka Panguva Yepamuviri makemikari anoumba vachishandisa kwakajairika Kubika uye mupise. Kana "mvura nyoro", iye kwenguva refu hapana akabhadhara ruremekedzo.

Naizvozvo, vagari venyika Air nyika, kuNorthern Urals uye Muganhu Onega uye Ladoga madhamu kwoupenyu upise mvura pasi chicherwa kugutsikana, kunyange muchiziva kuti sezvamunoita izvozvi mvura kunotungamirira pave nezvirwere zvakawanda, kusanganisira chinopedza Disc chirwere, kusimba, uye BP. Kwenguva refu, vanachiremba uye mabasa zvemhoteredzo ndezvaJehovha mvura "nyoro" iri chaizvo zvakanaka, muchitenda kuti anopa vashoma utano ngozi pane doro mineralized mvura. Asi wakatendeuka kubva kuti vagari nharaunda idzi nokukurumidza anoparadza zino enamel, vakadzi kuziva zvakawanda abnormalities panguva yepamuviri. Pane zvimwe zvinhu kwakaomarara utano.

Pari, munyika dzakawanda makemikari anoumba mvura iri kuva chinetso chikuru. Zviremera kunzwisisa kuti kwemvura yakachena yokunwa - ndicho pakona utano hwevanhu uye upenyu yakachengeteka yevanhu.
