Domestic wastewater treatment by real-scale electrocoagulation process.

In this study, domestic wastewaters originating from a settlement with a population of 17,500 were treated by electrocoagulation process in a real-scale EC plant and the economic applicability of the process was investigated. The removal efficiencies of control parameters in the influent and effluent of the real-scale treatment plant such as suspended solids (SS), biological oxygen demand (BOD), chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP) and changes of pH and conductivity parameters were monitored for 12 months. The obtained data were evaluated according to European Urban Wastewater Treatment Directive, Turkish Water Pollution Control Regulation and Turkish Urban Wastewater Treatment Regulation.

Distribution and bioaccumulation of organochlorine pesticides along the Black Sea coast.

Sediment, mussel, and seawater samples were collected three times during 2001-2003 at nine sampling stations along the mid-Black Sea coast of Turkey. The samples were analyzed with GC-ECD for contents of various organochlorine pesticides (OCPs) in the environment. DDT and its metabolites were detected at concentrations significantly above the detection limits.

Persistent organochlorine residues in sediments along the coast of mid-Black Sea region of Turkey.

The aim of this study is to determine aspects of water and surface sediment quality in the coastal zone of the mid-Black Sea, and of rivers discharging into it, by analyzing their organochlorine pesticides (OC) levels. Surface sediment samples and water samples were collected from 14 sites from the rivers Yeşilirmak, Abdal, Mert, Kürtün, Engiz and Kizilirmak. In sediments, Aldrin ranged from 19.
