Dvakrat letno izvajamo meritve prisotnosti potencialno toksi\u010dnih elementov in\u00a0nekaterih drugih onesna\u017eeval v reki Dravinji in v potoku Bre\u017enica. S kemijsko analizo\u00a0<\/span>vzorcev vod ugotavljamo koncentracije prisotnih nevarnih snovi kot so mangan, baker,\u00a0<\/span>nikelj, cink, kadmij, arzen, svinec, \u017eelezo, amonij, nitrat, detergenti in fenoli.\u00a0 Merimo\u00a0<\/span>tudi pH vode, dolo\u010dimo barvo, motnost in vonj. Na terenu je potrebno nujno opazovati\u00a0<\/span>vonj, obarvanost, pene in druge o\u010dem vidne spremembe, saj nam prav to pove, da je\u00a0<\/span>voda onesna\u017eena.<\/span><\/p>

Dosedanje meritve so pokazale, da se nevarne snovi nahajajo tako v reki Dravinji kot\u00a0tudi v potoku Bre\u017enica, kar pomeni, da predstavljajo nevarnost za vsa \u017eiva bitja. Ob\u00a0<\/span>primerjavi izmerjenih vrednosti in dovoljenih vrednosti v vodi smo ugotovili, da izmerjene\u00a0<\/span>vrednosti prisotnih nevarnih onesna\u017eevalcev v reki Dravinji in v potoku Bre\u017enica ne\u00a0<\/span>presegajo dovoljene vrednosti za pitno vodo. To pa \u0161e ne pomeni, da je voda pitna! Zato\u00a0<\/span>je potrebno narediti \u0161e nadaljnje raziskave in analize vode.<\/span><\/p>

Z raziskavami smo ugotovili, da sta reka Dravinja in potok Bre\u017enica onesna\u017eena z\u00a0nevarnimi snovmi, kar lahko pripi\u0161emo predvsem odpadni vodi, industriji in\u00a0<\/span>intenzivnemu kmetijstvu.<\/span><\/p>

Onesna\u017eevanje vode je nevarno za vsa \u017eiva bitja in posledi\u010dno tudi za nas, ljudi.\u00a0Voda je del narave, zato bi moral vsak od nas poskrbeti, da jo \u010dim manj onesna\u017euje. Je\u00a0<\/span>vir \u017eivljenja, zato moramo prav vsi skrbeti za \u010disto\u010do vode. Z vodo moramo ravnati\u00a0<\/span>skrbno in preudarno. Reke in potoki naj ne bodo odlagali\u0161\u010da odpadkov. Ohranjajmo vodo\u00a0<\/span>in ohranjajmo \u017eivljenje. Brez vode tudi nas ni. Voda odseva na\u0161 odnos do narave.<\/span><\/p>

Z raziskavo \u017eelimo krepiti na\u0161 pozitiven in korekten odnos do vode in narave.<\/p>

Analizo vode naredimo s t. i. hitrimi testi. Vzorcu vode po navodilih dodamo\u00a0posamezne reagente. Pote\u010de kemijska reakcija s snovjo, ki\u00a0 jo \u017eelimo dolo\u010diti.\u00a0<\/span>Pri tem pride do spremembe barve raztopine. Barvo raztopine primerjamo z barvo na\u00a0<\/span>prilo\u017eeni barvni lestvici in od\u010ditamo koncentracijo nevarne snovi, ki\u00a0 jo dolo\u010damo.\u00a0<\/span>Vrednosti primerjamo z dovoljenimi koncentracijami prisotnosti v pitni vodi.<\/span><\/p>
