Abstract:

The present work was conducted to study the physical, chemical and microbiological characteristics of the marine water along the Mina coastline in Tripoli city Northern Lebanon, in order to assess its quality and its impact on the marine ecosystem. Physico-chemical parameters and heavy metals concentrations were determined using standard analytical procedure. The results of the physico- chemical analysis were obtained in the following range during June and November respectively; temperature (24-25°C),(24-24.8°C); pH (5.25-8.75), (4.2-8.45); dissolved oxygen (1.38-7.8mg/L), (2.01-7.8mg/L); electrical conductivity (26.7- 1500 ms/cm), (43.1-1650 ms/cm) total dissolved solids(17355-975000 ppm), (280150-1072500 ppm). Chemical analysis of seawater samples has shown that the values of the ionic concentrations in non-contaminated areas were in accordance with the international standard for sea. Trace metals concentrations (mg/l) were evaluated, Cr, Cu and Pb recorded values high levels that exceeded the TRV. Results of microbial analysis for heterotrophic bacteria, total and fecal coliform, Salmonella sp and Shigella sp indicated significant levels of pollution indicating pollution from untreated sewage. To study the risk assessment, sediment samples were analyzed for the detection of trace metals concentrations. Results showed that 3 out of 23 sites showed high value of contamination factor whereas the rest of the sites showed average values below the guideline.
