Concentrations of inorganic pollutants, pesticides and PCBs were measured in 42 sources including rivers, streams, and industrial and domestic discharge points along the Turkish Black Sea coast in three seasons of the year 1993, The measured concentrations were compared with water quality standards currently effective in Turkey in order to determine the levels of pollution in the rivers and streams, Concentrations were also combined with the water discharge data to determine annual loads of pollutants discharged from each source into the Black Sea, Concentrations of measured parameters were much higher in domestic and industrial discharges, as expected, Most of the rivers and streams were polluted with organic material, nitrogen and phosphorous species due to discharges of untreated domestic wastes into these streams. Metal concentrations measured in the rivers and streams were fairly low due to the lack of extensive industrialization in the drainage areas of the streams, Some of the small streams, including the Neyren, Kilimli, Zafir and Tabakhane streams, are heavily polluted and were identified as sources having the potential to generate hot spots along the coast. annually, a total of 39.700 tons of nitrogen, 3.700 tons of phosphorous, 15 tons of Cd, 340 tons of Cu, 60 tons of Ph, 1.200 tons of Zn, 12 tons of heptachlor, 11 tons of aldrin, 31 tons of dieldrin, 180 tons of endrin and 500 tons of DDT are discharged from Turkish sources into the Black Sea. Except for trace metals, rivers and streams dominate the flux of pollutants, Large industries along the coast that discharge their wastes directly to the Black Sea account for a significant fraction of the annual metal discharges. Pesticides and PCBs were detected in most of the sources included in the study indicating their illegal use in agriculture. The Sakarya river was the most important source of pesticides.

Geostatistical analysis of bathing water quality in Turkey
Doğan, Nazlı Barçın; Yılmazel Tokel, Yasemin Dilşad; Department of Environmental Engineering (2019)
In this study geostatistical methods were applied to critically analyze historical bathing water quality (BWQ) data available for Turkish coastal areas. The specific objective of this study is the determination of the critical bathing sites of Turkey. In order to determine the critical bathing sites, a geostatistical method called indicator kriging is used via ArcGIS. Indicator kriging was applied using three microbial BWQ parameters, namely total coliforms (TC), fecal coliforms (FC) and fecal streptococci ...
Spatial distribution and source identification of persistent organic pollutants in the sediments of the Yesilirmak River and coastal area in the Black Sea
Dinc, Burak; ÇELEBİ, AHMET; Avaz, Gulsen; Canl, Oltan; Guzel, Baris; EREN, BEYTULLAH; Yetiş, Ülkü (2021-11-01)
Surface sediments from the Yes,ilirmak River and the near coastal area in the Black Sea were collected using sediment traps to assess the spatial distributions of persistent organic pollutants and find their potential sources. Analyses were carried out to determine the concentrations of the persistent organic pollutants of seventeen polychlorinated dibenzo-p-dioxins and dibenzofurans, sixteen polycyclic aromatic hydrocarbons, seven polychlorinated biphenyls, and eight organochlorine pesticides using high-re...

Water level and fish-mediated cascading effects on the microbial community in eutrophic warm shallow lakes: a mesocosm experiment

Information on the effects of water level changes on microbial planktonic communities in lakes is limited but vital for understanding ecosystem dynamics in Mediterranean lakes subjected to major intra- and inter-annual variations in water level. We performed an in situ mesocosm experiment in an eutrophic Turkish lake at two different depths crossed with presence/absence of fish in order to explore the effects of water level variations and the role of top-down regulation at contrasting depths. Strong effects...
Water quality, pollution and conservation
Yetiş, Ülkü (2006-10-12)
This chapter presents the main water pollutants and their impacts on the environment as well as the water quality parameters (physical, chemical and biological) that are used in water resources assessment and management. The water quality of river, streams, lakes and groundwater is reviewed. Remediation and preventive measures are also examined. Water conservation practices and its effective use are analyzed for system users and system operators.
