In this study, some heavy metal concentrations (Pb, Zn, Fe, Cr, Cu), suspended sediment, chemical oxygen demand (COD), biological oxygen demand (BOD), cyanide, phenol, fecal coliform and total coliform water parameters were determined in the streams (Kucuk Melen, Asarsuyu, Ugursuyu, Buyuk Melen and Aksu) of Buyuk Melen Watershed that provides drinking water to Istanbul in Western Black Sea Region of Turkey. Measurements of water quality parameters were done monthly in eleven separate stations (4 in Kucuk Melen Stream, 1 in Asarsuyu Stream, 1 in Ugur Stream, 1 in Aksu Stream and 4 in Buyuk Melen Stream) from August 2001 to August 2002. The seasonal changes in water quality parameters were evaluated statistically. The results, the parameters, COD, BOD, Pb, Zn, Fe, Cr, Cu, cyanide, fecal coliform, total coliform and suspended sediment showed significant differences among seasons and streams (ANOVA; P <0.05). According to Turkish Standarts (TS) 266, European Union (EU) and World Health Organization (WHO) criteria, the maximum values of each parameter in streams within the Buyuk Melen watershed are recorded and evaluated in this study.

In this paper, a mathematical model was developed to determine the standards of a unit park area per person in a neighbourhood park based on social–cultural and economic conditions of a town or a city in a country. This way, a different dimension was given by the issue of looking at the unit size required in a park having attendants from different socio-cultural and economic backgrounds. The model involves only the small-scaled recreational activities such as sitting–resting in neighbourhood parks. Studies dealing with the factors affecting the use of open green areas where individuals utilize during leisure time were evaluated. The parameters used were determined and checked as to whether they could be used in this study, and based on the results the model was developed for a neighbourhood park.The model was applied in Trabzon as a case study and the unit area required in a neighbourhood park per person was calculated. The optimal size of a neighbourhood park for the city of Trabzon has been found as 1.22–1.52m2/person for the provision of basic facilities and in the case of having all the facilities required for the optimal size of a park it is 3.61–4.08m2/person in the survey. Standards, both basic and best case as identified with this study for city parks in Trabzon, suggest that the current standards for park size in the public improvement regulations are not appropriate.

... Every aquatic ecosystem is a unique natural feature, and the study of each system in detail is necessary for case-bycase assessment of ecological threats (Hakanson, 2004). Water resources are under pressure and in danger as a result of potential pollution and contamination risks due to over use and misuse of the resources all over the world (Karagul et al., 2005). There are reports on long-term decrease in the area of Lake over the last 30 years due to the siltation and climate change (Su and Jassby, 2000). ...
