Abstract

Kada se radi o primarnim hranjivim tvarima koje se nalaze u podzemnim vodama te koje u prekomjernim količinama zagađuju jezera, potoke i močvare najčešće se upravo radi o fosforu i dušiku. Upravo je dušik taj koji je ključan element za proces proizvodnje kako biljnog tako i životinjskog tkiva. Navedeni se smatra iznimno bitnim s obzirom da putem istog biljke i životinje sintetiziraju bjelančevine. Dušik ulazi u ekosustav u nekoliko kemijskih oblika i javlja se kod drugih otopljenih tvari ili oblika, kao što su tkiva živih i mrtvih organizama. Najpoznatiji oblik u kojem se pojavljuje dušik u vodenom okolišu je nitrat ion, a moguće ga je pronaći i u atmosferskoj vlagi.
Ukoliko se radi o većim koncentracijama isti je štetan kako za biljni tako i za životinjski svijet. Nitrati u vodi mogu uzrokovati teške bolesti kod dojenčadi i domaćih životinja. Temeljni cilj rada je usredotočiti se na spojeve dušika u podzemnim vodama, prikazati povezanost između zagađenja i onečišćenja hranjivim solima dušika i hidrogeoloških obilježja vodonosnika na primjeru Republike Hrvatske.

Abstract (english)

When it comes to primary nutrients that are found in groundwater and which pollute lakes, streams and swamps in excessive amounts, it is most often phosphorus and nitrogen. It is nitrogen that is the key item for the production process of both plant and animal tissue. This is considered to be extremely important since plants and animals synthesize proteins through the same. Nitrogen enters the ecosystem in several chemical forms and also occurs in other dissolved particles or forms, such as tissues of living and dead organisms. The most well-known form in which nitrogen occurs in the aquatic environment is the nitrate ion, and it can also be found in atmospheric moisture.In the case of higher concentrations, it is damaging for both flora and fauna. Nitrates in water can cause severe illness in infants and domestic animals. The basic goal of the paper is to focus on nitrogen compounds in groundwater, show the connection between pollution and pollution with nitrogen nutrient salts and hydrogeological characteristics of aquifers on the example of the Republic of Croatia.
