Kakvoća mora na morskim plažama u Dubrovačko-neretvanskoj županiji u 2006. godini

U okviru višegodišnjeg praćenja kakvoće mora na morskim plažama Zavod za javno zdravstvo Dubrovačko-neretvanske županije proveo je ispitivanje kakvoće mora prema Županijskom Programu praćenja kakvoće mora na morskim plažama za sezonu kupanja 2006. godine. Prema definiranim kriterijima Uredbe o standardima kakvoće mora na morskim plažama, Higijensko-analitički laboratorij Zavoda je uzorkovao, analizirao i ocjenjivao kakvoću mora na 88 plaža u Županiji, od kojih su 4 plaže uključene u projekt Plava zastava. Nakon završenih ispitivanja u 15-dnevnom intervalu, rezultati su dostavljani jedinicama lokalne samouprave te objavljivani putem informativnih glasila. Rezultati ispitivanja u 2006. godini pokazali su da je more u Dubrovačko-neretvanskoj županiji visoke kakvoće

The Influence of Electromagnetic Field on Viability of Marine Microalgae Tetraselmis Suecica and Bacteria Escherichia Coli and Enterococcus Faecalis

The objective of this study was to determine whether the use of the electromagnetic field (EMF) of 50 Hz frequency and magnetic induction of 0.25 T could make for successful inactivation of a phytoplankton species, namely, marine microalgae Tetraselmis suecica and two bacteria strains; Escherichia coli and Enterococcus faecalis. A number of laboratory electromagnetic field tolerance experiments with the selected organisms was performed; each microorganism was treated for various lengths of time; 1, 5 and 10 minutes, and in three various media with special regards to the conductivity. Bacteria were exposed to high, moderate and extremely low conductivity media, and the microalgae to high, low and extremely low conductivity media. The microbial viability was checked by counting the bacterial colony forming units, as well as alive and dead stained microalgae cells. It was found that the time of exposure to the EMF had a profound effect on the viability of T. suecica only in the extremely low conductivity media, and that it did not affect the viability of E. coli or E. faecalis at all

Status of faecal pollution in ports: A basin-wide investigation in the Adriatic Sea

Ports are subject to a variety of anthropogenic impacts, and there is mounting evidence of faecal contamination through several routes. Yet, little is known about pollution in ports by faecal indicator bacteria (FIB). FIB spatio-temporal dynamics were assessed in 12 ports of the Adriatic Sea, a semi-enclosed basin under strong anthropogenic pressure, and their relationships with environmental variables were explored to gain insight into pollution sources. FIB were abundant in ports, often more so than in adjacent areas ; their abundance patterns were related to salinity, oxygen, and nutrient levels. In addition, a molecular method, quantitative (q)PCR, was used to quantify FIB. qPCR enabled faster FIB determination and water quality monitoring that culture-based methods. These data provide robust baseline evidence of faecal contamination in ports and can be used to improve the management of routine port activities (dredging and ballast water exchange), having potential to spread pathogens in the sea

Performance characteristics of the temperature-modified ISO 9308-1 method for the enumeration of Escherichia coli in marine and inland bathing waters

This study defines performance characteristics of the temperature- modified ISO 9308-1 method for E. coli enumeration in bathing water. After a 4-hour resuscitation period at 36 ± 2 °C, the incubation temperature was changed to 44 ± 0.5 °C. Elevated incubation temperature significantly suppressed the growth of thermo- intolerant bacteria, and enhanced the selectivity of Chromogenic Coliform Agar (CCA) up to 49.5% for inland and up to 66.0% for coastal water. Consequently, most of the selectivity- related performance characteristics are improved. Relative recovery was determined by comparing an alternative method against the reference, ISO 9308- 1:2014 method, following the criteria set out in ISO 17994:2014. Temperature modification did not significantly alter the results and the methods were evaluated as “not different” for both, coastal and inland waters. Chromogenic Coliform Agar was assessed as a suitable medium for reliable E. coli enumeration in bathing water when incubated for 17–19 h at 44 ± 0.5 °C after the 4–5 h resuscitation period at 36 ± 2 °C
