Concentrations of Cr, Mn, Fe, Co, Ni, Cu, Cd and Pb were determined by using ICP-MS. The surface water and sediment samples were collected monthly, from at 5 stations between June 2013 and May 2014. Descriptive statistical analysis including One-way ANOVA, significance (0.05) was done. Important differences in the mean values were tested with Duncan's multiple range test. Moreover, with the purpose for determining the level of pollution, the methods of the factor of sediment enrichment factor and the index of geoaccumulation were applied. Cu, Pb, Ni and Cd concentrations in water samples were very higher than RSWQM standards, Cu, Mn, Fe and Pb concentrations were higher than the EPA standards and also Cu, Mn, Fe, Pb, Cu and Ni concentrations were higher than the WHO guidelines. The result of sediment enrichment factor and geoaccumulation index reveals that surface sediments of the Yaglidere Stream are unpolluted. Consequently, it can be concluded that the concentrations of heavy metals in water from Yaglidere Stream are generally higher than the RSWQM, WHO and EPA standards. It can be concluded that the heavy metal pollution level is high in Yaghdere Stream and it will be good to adopt protective measures before it's too late

Ensuring safe access to healthy water is necessary to maintain life. We can observe that the total freshwater source from all existing ecosystems is only 2.5%. Furthermore, fresh water is not readily available for the utilisation of living beings because more than 68% of freshwater is located in the poles and on mountains in the form of snow and ice, which makes it more difficult to obtain. 31.4% of fresh water is present as groundwater, whereas only 0.3% of fresh water is present in surface waters. Furthermore, in the case of surface waters, the distribution of fresh water is as follows: 87% in lakes, 11% in marshes and 2% in rivers [1]. Currently, the

The 20 died seahorse individuals were collected from regional fishermen at the Tirebolu coast in Novem-ber 2010. In all fish samples, mean of standard length was calculated as 78±19.68 mm, mean weight was 2.02±0.34 g. The highest levels of Pb, Zn, Cu, Cd were found in muscle tissue in descending order and their values were 1750,6; 197,4;121,32;1,568 ppm respectively. Causes of metal concentrations levels in tissues of seahorse were attributed to atmospheric sources like fossil fuel oil consumption and to territorial sources as mine reservoirs (Cu, Pb,Zn).

Bu calisma Ekim 2015 ile Eylul 2016 tarihleri arasinda Kucuksu Golet’inde (Taskopru, Kastamonu) belirlenen uc istasyonda aylik ornekleme ile gerceklestirilmistir. Golet icme suyu ve sulama suyu ihtiyacini karsilamak icin yapilmistir. Bu calismanin temel amaclari, Kucuksu Golet’inde fizikokimyasal parametreler ve agir metal iceriginin aylik ve mevsimsel degisimini gozlemlemek, su kalitesi ozelliklerini ve sucul yasam acisindan uygunluk seviyesini belirlemek ve ayrica su kalitesini Yuzeysel Su Kalitesi Yonetimi Yonetmeligine gore siniflandirmaktir. Toplam 21 fizikokimyasal parametre ve 7 agir metal incelenmistir. Kucuksu Golet’i su kalitesi Yuzey Su Kalitesi Yonetim Yonetmeligi (YSKYY)’nin kita ici su kaynaklarinin siniflarina gore SINIF I-III olarak bulunmustur. Fiziksel ve kimyasal analizlerin bulgulari karsilastirildiginda, bu goletin bir oligotrof karakterde oldugu gorulur. Bu sonuclar acisindan, Kucuksu Golet’i suyu genellikle sucul organizmalar icin uygundur. Bu su kaynaginin kirlilik baskisi altinda oldugu, daha da kirlenmemesi, su kalitesinin korunmasi acisindan periyodik olarak duzenli olarak izlenmesinin gerektigi sonucuna ulasilmistir.

The 20 died seahorse individuals were collected from regional fishermen at the Tirebolu coast in Novem-ber 2010. In all fish samples, mean of standard length was calculated as 78±19.68 mm, mean weight was 2.02±0.34 g. The highest levels of Pb, Zn, Cu, Cd were found in muscle tissue in descending order and their values were 1750,6; 197,4;121,32;1,568 ppm respectively. Causes of metal concentrations levels in tissues of seahorse were attributed to atmospheric sources like fossil fuel oil consumption and to territorial sources as mine reservoirs (Cu, Pb,Zn).

Örneklemelerde 200 µm ağ göz açıklığı olan Unesco WP2 zooplankton kepçesi kullanılarak, derinlikleri 10–74 m arasında değişen 34 istasyonda vertikal örneklemeler yapılmıştır. Örneklerin incelenmesi sonucunda 6 familyaya ait 18 tür tespit edilmiştir. Bu türlerden 5'i Parathemisto oblivia (Kroyer), Lestrigonus curcipes (Bovallius,1889), Lestrigonus macrophytalmus (Vosseler, 1901), Primno latreillei (Stebbing, 1888), Paralycae gracilis (Claus, 1879). İzmir Körfezi için yeni kayıttır. Bu türlerin Dış I, İç ve Orta Körfez'de bulunmadığı belirlenmiştir
