Pagal i\u0161 gydytoj\u0173 gautus prane\u0161imus apie n\u0117\u0161\u010di\u0105sias ir k\u016bdikius, kuri\u0173 maistui naudojamas \u0161achtini\u0173 \u0161ulini\u0173 vanduo, 2022 m. Lietuvoje i\u0161tirti 582 \u0161achtiniai \u0161uliniai, siekiant nustatyti tar\u0161\u0105 nitritais ir nitratais. Vandens kokyb\u0117s reikalavim\u0173 neatitiko 27 proc. \u0161ulini\u0173.<\/p>\n

Daugiausiai \u0161ulini\u0173, kuri\u0173 vanduo neatitiko nustatyt\u0173 kokyb\u0117s rodikli\u0173, buvo Kauno apskrityje \u2013 tokie vandens \u0117miniai sudar\u0117 34 proc. i\u0161 vis\u0173 tirt\u0173 \u0161ulini\u0173, \u0160iauli\u0173 apskrityje \u2013 34 proc., Panev\u0117\u017eio apskrityje \u2013 29 proc., Alytaus \u2013 28 proc., ma\u017eiausiai \u2013 Klaip\u0117dos apskrityje, kur nustatyt\u0173 norm\u0173 neatitiko 17 proc. \u0161ulini\u0173, Tel\u0161i\u0173 apskrityje \u201319 proc.<\/p>\n

Kaip nitritai ir nitratai atsiranda vandenyje?<\/strong>
\n\u012e kastinius (\u0161achtinius) \u0161ulinius vanduo patenka i\u0161 neapsaugoto nuo pavir\u0161in\u0117s tar\u0161os gruntinio vandens sluoksnio, kuris gali b\u016bti u\u017eter\u0161iamas d\u0117l netinkamos \u017eem\u0117s \u016bkio veiklos (naudojant per daug tr\u0105\u0161\u0173, m\u0117\u0161lo), greta esan\u010di\u0173 grunto tar\u0161os \u0161altini\u0173 \u2013 s\u0105vartyn\u0173, ferm\u0173 ir kit\u0173 tar\u0161os objekt\u0173. Vandens u\u017eter\u0161tum\u0105 nitratais ir nitritais taip pat gali lemti netinkamas \u0161achtinio \u0161ulinio \u012frengimas bei prie\u017ei\u016bra.<\/p>\n

Labai svarbu, kad \u0161ulinys b\u016bt\u0173 \u012frengtas auk\u0161\u010diau u\u017e galimos tar\u0161os objektus pagal gruntinio vandens tek\u0117jimo krypt\u012f. Jeigu tokios galimyb\u0117s n\u0117ra, tuomet b\u016btina \u012frengti sanitarines apsaugos zonas iki tar\u0161os \u0161altini\u0173 ne ma\u017eesnes kaip 25 m, iki gara\u017eo, \u0161iltnamio, \u016bkini\u0173 patalp\u0173 \u2013 10 m, gyvenamo namo \u2013 7 m, lauko nuotakyno \u2013 15 m.<\/p>\n

\u0160ulini\u0173 \u012frengimo reikalavimus nustato Lietuvos higienos norma \u201e\u0160ulini\u0173 ir versmi\u0173 kapta\u017eo \u012frengini\u0173 visuomen\u0117s sveikatos saugos reikalavimai\u201c<\/a>.<\/p>\n

Pavojingiausias n\u0117\u0161\u010diosioms ir k\u016bdikiams<\/strong>
\nSvarbu atminti, kad nitritais ir nitratais u\u017eter\u0161tas vanduo neturi specifinio kvapo, skonio ar spalvos.\u00a0 Tod\u0117l nei plika akimi, nei uostant ar ragaujant ne\u012fmanoma nustatyti, kad vanduo u\u017eter\u0161tas. Nitrit\u0173 ir nitrat\u0173 pa\u0161alinti patiems taip pat negalima \u2013 nei virinant, nei filtruojant vanden\u012f buitiniais filtrais jie nedingsta.<\/p>\n

Su vandeniu ir maistu \u012f \u017emogaus organizm\u0105 patek\u0119 nitratai virsta nitritais, sutrikdo kraujo deguonies perne\u0161im\u0105 ir sukelia vidin\u012f deguonies bad\u0105 (methemoglobinemij\u0105), kuris labai pavojingas k\u016bdikiams iki 6 m\u0117nesi\u0173 am\u017eiaus, nes d\u0117l \u0161ios b\u016bkl\u0117s kyla net k\u016bdiki\u0173 mirties rizika.<\/p>\n

Jeigu n\u0117\u0161\u010dioji vartoja \u0161iomis chemin\u0117mis med\u017eiagomis u\u017eter\u0161t\u0105 vanden\u012f, d\u0117l nuolatinio deguonies stygiaus kraujyje gimsta ma\u017eesnio svorio ir silpnesni k\u016bdikiai, l\u0117t\u0117ja j\u0173 fizinis bei psichinis vystymasis.<\/p>\n

\u0160ulin\u012f tinkamai \u012frengti ir pri\u017ei\u016br\u0117ti yra pakankamai sud\u0117tinga, tod\u0117l specialistai pataria jungtis prie centralizuotai tiekiamo vandens sistem\u0173, kuri\u0173 prie\u017ei\u016bra yra grie\u017etai reglamentuojama ir kontroliuojama. Taip u\u017etikrinamas kokybi\u0161kas ir saugus sveikatai vanduo.<\/p>\n
