Narta Lagoon is one of the biggest Lagoons in Albania. It is situated in the southern part of the Vjosa River delta. Two canals in the northwest and southwest parts of the lagoon connect it to the Adriatic Sea. These artificial canals enable the water exchange process with the sea during tidal flow. Vjose - Narta area is considered a Protected Landscape, so environmental monitoring is important. Setting and design: Water samples were taken monthly, at six evenly distributed sample stations. The study was conducted from January – to December 2018. Materials and methods: The assessment of microbial contamination was performed with the MPN method. Total coliform, fecal coliform, and fecal streptococci were tested as fecal contamination indicators. PH and salinity were the physicochemical parameters analyzed. Conclusions: the cleanest sampling station is the one near contact with the seawater. The most polluted stations are stations 2, 4, and 6. Temperature values range from 5 oC in January to 33 oC in August. Lagoon pollution is caused by an anthropogenic factor as well as a lack of appropriate cleaning strategies.
Vlora bay represents one of the most attractive and important beaches of Albanian seacoast. Coastal waters are widely used for a series of recreative activities. Therefore, it is needed a periodical assessment of water quality in order to improve public health. The aim of this research study was monitored and evaluation of water quality in correlation of the dynamics of fecal bacteria indicators in Vlora bay. Setting and design: The microbiological indicator analyses were conducted in 2019 at regular time intervals during two seasons: spring and summer. Water samples were collected at 6 sampling stations eventually distributed along the coastline. Materials and Methods: Total and fecal coliform were analyzed using one of the Coliform standard methods -MPN. In order to give a completed pattern of the study area, we measured some of the physical-chemical parameters such as: temperature, pH and salinity. The results: Temperature values vary from 11.6 o C in March to 23.7 o C in August. During summer time, our data show a higher concentration level of fecal bacteria almost in all the sampling stations. This might be due overpopulation of the coastline, especially in this period of year. Conclusions: This study shows that the sea water along Vlora coastline is largely indicated by anthropogenic sources. A lower quality of water is noticed particularly around the locations of urban sewage discharges.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
