Abstract
Monitoring kakvoće mora za kupanje se u Republici Hrvatskoj provodi u cilju očuvanja zdravlja kupača, a propisan je Uredbom o kakvoći mora za kupanje (NN 73/08). Mikrobiološki pokazatelji koji se određuju su crijevni enterokoki i Escherichia coli, kao pokazatelji fekalnog onečišćenja. Druge značajke kakvoće mora koje se prate su: temperatura mora i zraka, vjetar, kiša, salinitet i vidljivo onečišćenje. Cilj ovog istraživanja bio je ispitati pojavnost Salmonella spp. u moru za kupanje na užem području grada Rijeke, u različitim okolišnim uvjetima. Dodatno, ispitana je povezanost pojavnosti Salmonella spp. s pokazateljima fekalnog onečišćenja te s dodatnim fekalnim (C. perfringens) i ne-fekalnim (S. aureus, P. aeruginosa, UBB/37/22) pokazateljima mikrobiološkog opterećenja. Prisutnost Salmonella spp. povezana je s vodenim tokovima u koje se ispušta otpadna voda bez prethodne obrade. Za ovo istraživanje odabrane su četiri plaže u zapadnom dijela grada Rijeke, koje imaju 6 lokacija uzorkovanja. U cilju postizanja gušće mreže lokacija uzorkovanja, istraživanje je provedeno na 6 dodatnih (profilnih) lokacija, što ukupno čini 12 lokacija. U okviru projekta EUROBATH uzorkovanje se na navedenim lokacijama provodilo tijekom tri sezone kupanja, jednom tjedno. Salmonella je dokazana u 41 uzorku (3,7%) od kojih je 28 označeno kao more pogodno za kupanje. Rezultati pokazuju da salinitet i sunčevo zračenje značajno utječu na koncentraciju Salmonella u moru. Dotok slatke vode u more je izvor mikrobiološkog onečišćenja, a pojavnost Salmonella u moru uvelike ovisi o količini oborina. Dokazano je da praćenje samo rutinskih pokazatelja, E. coli i enterokoka ne isključuje mogućnost kontakta kupača sa bakterijama vrste Salmonella.
Abstract (english)
The monitoring of sea water quality for swimming in the Republic of Croatia is carried out with the aim of preserving the health of swimmers and is regulated by the Regulation on the Quality of Sea Water for Swimming (NN 73/08). The microbiological indicators that are determined include intestinal enterococci and Escherichia coli, as indicators of fecal contamination. Other characteristics of sea water quality that are monitored include sea and air temperature, wind, rain, salinity, and visible pollution. The aim of this study was to investigate the occurrence of Salmonella spp. in swimming sea water in the narrower area of the city of Rijeka, under different environmental conditions. Additionally, the study examined the correlation between the occurrence of Salmonella spp. and indicators of fecal contamination, as well as additional fecal (Clostridium perfringens) and non-fecal (Staphylococcus aureus, Pseudomonas aeruginosa, UBB/37/22) indicators of microbiological load. The presence of Salmonella spp. is associated with watercourses where wastewater is discharged without prior treatment. For this study, four beaches in the western part of the city of Rijeka were selected, having 6 sampling locations in total. To achieve a denser network of sampling locations, the study was conducted at an additional 6 (profile) locations, making a total of 12 locations. As part of the EUROBATH project, sampling at these locations was conducted during three swimming seasons, once a week. Salmonella was detected in 41 samples (3.7%), of which 28 were marked as suitable for swimming. The results show that salinity and solar radiation significantly affect the concentration of Salmonella in the sea water. The inflow of fresh water into the sea is a source of microbiological contamination, and the occurrence of Salmonella in the sea greatly depends on the amount of rainfall. It has been proven that monitoring only routine indicators, E. coli and enterococci, does not exclude the possibility of swimmers coming into contact with Salmonella bacteria.
