\u0160\u012f nedidel\u012f tyrim\u0105 atlikti paskatino vienas mano internetinio puslapio lankytojas.

Tyrimo metodika labai paprasta: \u012f vieno litro talpos sta\u010diakamp\u012f skaidraus plastiko ind\u0105 \u012fpyliau apie 800 mL \u010diaupo vandens su \u017einoma nitrat\u0173 koncentracija (119 mg\/L). \u0160\u012f ind\u0105 pasta\u010diau \u012f \u0161aldiklio kamer\u0105\u00a0 ir ten laikiau tol, kol ma\u017edaug tre\u010ddalis vandens virto ledu. Tuomet ind\u0105 i\u0161\u0117miau i\u0161 \u0161aldiklio ir led\u0105 atskyriau nuo nesu\u0161alusio vandens. Palaukus tol, kol kambario temperat\u016broje ledas virto skys\u010diu, jame v\u0117l pakankamai tiksliu spektrometriniu metodu buvo nustatyta nitrat\u0173 koncentracija. Be nitrat\u0173 koncentracijos buvo i\u0161matuotas abiej\u0173 vandens m\u0117gini\u0173 savitasis elektros laidis (SEL). Priminsiu, kad SEL yra proporcingas drusk\u0173 koncentracijai vandenyje. \u0160io nedidelio tyrimo rezultatai pateikti lentel\u0117je.<\/p>\n

K\u0105 parod\u0117 \u0161is nedidelis tyrimas? Jis parod\u0117, kad tokiu b\u016bdu bet kokiame vandenyje galima \u017eenkliai suma\u017einti \u012fvairi\u0173 drusk\u0173 (tame tarpe ir nitrat\u0173) koncentracijas. Nema\u017eiau svarbus ir kitas klausimas: kiek ekonomi\u0161kas yra \u0161is b\u016bdas? Atsakymo \u012f \u0161\u012f klausim\u0105, deja,\u00a0 neturiu.<\/p>\n
