Sea quality analysis in the Zadar County

Jadransko more je oligotrofno more sa razvedenom obalom. Ubraja se u najčišća mora Europe. Međutim, u ljetnim mjesecima, zbog velikog broja turista, potrebno je dodatno pratiti kakvoću morske vode da bi se utvrdilo postoji li onečišćenje, otpadne vode, fekalije te brojni mikroorganizmi koji su uzročnici različitih bolesti, a mogu biti opasni za ljudsko zdravlje. Zbog toga Zavod za javno zdravstvo provodi ispitivanja o kakvoći mora u sezoni kupanja, točnije od 5. do 9. mjeseca kada su dostupni podaci o kvaliteti morske vode. Osim podataka o onečišćenju i broju mikroorganizama, u analizama kakvoće mora prikazana su klimatska, geološka te hidrološka obilježja. U radu su obrađene neke od najvećih i najpoznatijih plaža grada Zadra, Biograda, Nina i Paga. Analizom je utvrđeno da je kakvoća mora navedenih plaža uglavnom bila ocijenjena izvrsnim ocjenama u 2017. godini. Međutim, zbog sve većeg broja turista na ovom području potrebno je kontinuirano pratiti kakvoću morske vode kako bi se što prije moglo reagirati ukoliko dođe do onečišćenjaThe Adriatic Sea is oligotrophic sea with the indented coastline. It is considered as one of the cleanest sea of Europe. However, in the summer, due to the large number of tourists, it is necessary to control the quality of sea water to determine is there any contamination, waste water, feces or microorganisms that cause various diseases and can be dangerous to human health. For this reason, the Public Health Institute performs seawater quality tests, from May to September where seawater quality data are available. In addition to the pollution and the number of microorganisms, seawater quality analyzes show climatic, geological and hydrological characteristics. In this paper seawater quality of some of the largest and most famous beaches of Zadar, Biograd, Nin and Pag were described. The analysis reviled that the quality of the mentioned beaches were mostly valued by excellent grades in 2017. However, due to the increasing number of tourists in this area, it is necessary to continuously monitor the quality of seawater to respond as soon as possible, if pollution occurs
