Determination of the Levels of Indicator Bacteria and Salmonella spp. in Chamelea gallina, L. and Seawater on the Coastline of Sile, Turkey
Indicator bacteria and Salmonella spp. were investigated in both Chamelea gallina and seawater from six stations on the coast- line of Sile, Turkey. Studies were carried out on 15 days from June to December in 1998-1999. Chamelea gallina samples which were collected at approximately 5-10 meters depth from the chosen stations were examined for faecal coliform, Escherichia coli and Salmonella spp. Bacteria numbers were highest in July and August. Bacteria distribution was found to be statistically significant between stations. No Salmonella spp. were detected in the samples
Determination of the Levels of Indicator Bacteria, Salmonella spp. and Heavy Metals in Sea Snails (Rapana venosa) from the Northern Marmara Sea, Turkey
Sea snail (Rapana venosa) samples were collected from the northern coast of the Marmara Sea and analyzed to determine bacteriological pollution in the form of Faecal coliform, Esherichia coli, and Salmonella spp. as well as to measure levels of the heavy metals, Zn, Pb, Cu, Cd, As using by atomic absorption spectrophotometer. Samples were collected through the June 2000 - November 2001 from the shore and from depths of 10 – 12 meters of the northern Marmara Sea. Within the total of 75 groups of R. venosa samples which consisted of at least 6 individuals in each group, the highest bacteriological values, 11 x 10³ cfu/g Esherichia coli, >24 x 10³ Faecal coliform, were determined in the August sampling
period. Salmonella spp. was determined in 2 groups of samples. Within the total of 55 groups of R. venosa samples, consisting of at least 3 individuals in each group, heavy metal levels ranged between Zn: 18.0–52.0 ppm, Pb: 0.52–1.25 ppm, Cu: 21.6–49.3 ppm, Cd: ND - 0.08 ppm. Arsenic was found below detection limit. No temporal variation was observed in the heavy metal concentrations
