In
the work, the results of dominant nutrients (N, P) and limiting quality
indicators are given, by localities, for the River Zeta for the period between
1996 and 2004. Those data illustrate an accelerated eutrofication of the river
during the recent years. At some localities, the process of succession,
replacement of water ecosystem with terrestrial one, has been caused during the
summer months. With the data analysis, supported by statistical programs, it has
been assessed that the cause of these processes is not only continued,
uncontrolled discharge of waste waters enriched with organic burden indirectly
or directly into the Zeta River drainage basin, but also an uncontrolled usage
of artificial fertilizers. Such a statement is also indicated by the values of
limiting quality indicators of the River Zeta.
Key
words: the Zeta
River, nutrients, water, protection.
U
radu su iznijeti rezultati dominantnih nutrijenata (N,P ) i limitirajućih
pokazatelja kvaliteta, po lokalitetima u periodu od 1996 do 2004 godine za
rijeku Zetu. Ti podaci ilustruju ubrzanu eutrofikaciju rijeke zadnjih godina. Na
nekim lokalitetima izazvan je proces sukcesije, smjene vodenog ekosistema
suvozemnim, tokom ljetnjih mjeseci. Analizom podataka, uz podršku statističkih programa, ocijenjeno je da uzrok ovim
procesima nije samo kontinuirano, nekontrolisano, puštanje otpadnih voda obogaćenih
organskim teretom indirektno ili direktno u sliv Zete, već i nekontrolisana
upotreba vještačkih đubriva. Na ovakvu tvrdnju upućuju i
vrijednosti limitirajućih pokazatelja kvaliteta vode rijeke Zete.
Ključne riječi: Zeta, nutrijenti, voda, zaštita.
