Bacteriological indicators of anthropogenic impact prior to and during the recovery of water quality in an extremely polluted estuary, Golden Horn, Turkey

Étude de l’influence des facteurs environnementaux sur la distribution de différentes populations bactériennes dans une station mytilicole de la lagune de Bizerte (Nord-Tunisie)

“…Cet effet d'apports continentaux sur la densité bactérienne a été bien mis en évidence dans d'autres sites conchylicoles par ASLAN-YILMAZ et al (2004);CASTANEDA CHAVEZ et al (2005);CROWTHER et al (2001);DONNISSON et ROSS (1999); LIZARRAGA-PARTIDA et CARDENAS (1996) et SHIBATA et al (2004. Aussi, LA ROSA et al (2001) ont signalé la concomitance entre l'augmentation en taux de bactéries fécales dans les eaux d'une station mytilicole avec la période pluvieuse (septembre et janvier).…”

“…Des résultats similaires ont été obtenus par ASLAN-YILMAZ et al (2004), CHANDRAN et HATHA (2005), DAVIES-COLLEY et al (1994) et SINTON et al (2002. Ces auteurs ont montré que l'augmentation en température pendant la saison estivale inactiverait les polluants fécaux.…”

Seasonal distribution of Trachurus mediterraneus (Steindachner, 1868) in the Golden Horn Estuary, İstanbul

“…Decreasing of the depth to the inner parts causes the distinct variability of dissolved oxygen caused by bacteriological (Aslan-Yılmaz et al, 2004) and phytoplanktonic (Taş et al, 2009) activity. Another gradient across the length of the Golden Horn is that of chlorophyll a and visibility (Secchi disk depths).…”

Golden Horn Estuary: Description of the ecosystem and an attempt to assess its ecological quality status using various classification metrics

“…About 4.5 million m 3 of anoxic sediment was dredged from the inner part and pumped into an abandoned stone quarry, increasing the water depth at this part to 4-5 m. After the construction of northern and southern sewerage trunk systems in 1999 and the opening of the floating bridges to ease water circulation in 2000, the pollution in the estuary began to decrease. Recent studies have shown that water quality and ecological conditions were remarkably improved after the rehabilitation activities (ASLAN-YILMAZ et al, 2004;GÖNÜLLÜ et al, 2006;YÜKSEK et al, 2006).…”

“…ÜNSAL, 1988;TUNCER et al, 2001;ASLAN-YILMAZ et al, 2004;ALTUNKAYNAK et al, 2005). The most comprehensive one, with a holistic approach (YÜKSEK et al, 2006), is assessing environmental changes through macro-and microbiological data and water quality parameters.…”
