Soil Quality Standards (SQSs) are considered as an important tool for management of contaminated sites. In order to manage adverse effects associated with soil contamination, risk-based SQSs are used worldwide. However, developing health risk-based SQSs is a challenging task. It involves comprehensive assessment of nationwide site characteristics (e.g. soil, hydrogeological, climatic properties), understanding of social behaviors that determine human exposure to soil pollutants (e.g. exposure scenarios and parameters), and making political decisions with regard to the economical concerns. To set fixed levels of SQSs that apply for various cases and that is protective of human health, conservative assumptions should be made. The level of conservativeness of the standards should not pose a challenge to the objectivity of the decision given and not force technical and financial resources. Regarding this challenge, a novel conceptual framework is developed for derivation of human health risk-based SQSs for Turkey. In this paper, the main elements of the established conceptual framework, the methods used for specification of the generic site characteristics, the information sources used for compilation of needed chemical and toxicological data, the political decisions taken, and the challenges encountered during these studies are presented. It is believed that the presented road map developed through the conceptual framework will be beneficial for other countries that are in the stage of deriving SQSs.

Development of risk based soil quality standards for Turkey İpek, Hatice Meltem; Ünlü, Kahraman; Department of Environmental Engineering (2011) Soil quality standards (SQSs) are one of the most important elements of management system for contaminated sites. In order to manage risks associated with soil contamination, risk based SQSs are used worldwide. However, in Turkey, the Soil Pollution Control Regulation in force was focusing mainly on the use of stabilized sludge on soil and was including standards for a limited number of parameters, mainly metals and some organic chemicals. Thus, existing SQSs were far away from providing common criteria for...
Modeling of settlement in saturated and unsaturated municipal landfills Durmusoglu, Ertan; Corapcioglu, M.Yavuz; Tuncay, Kağan (American Society of Civil Engineers (ASCE), 2006-07-01) Municipal solid waste (MSW) landfills are not only used to dispose the refuse in most economical way but also utilized as a viable land in today’s waste management strategy. Settlement prediction is an important issue in order to guarantee the integrity of any postclosure structure on landfills. In this study, landfill settlement in saturated and unsaturated landfills is investigated by developing a one-dimensional mathematical model and performing numerical experiments. Under the saturated conditions, the ...
Classification of commonly used pesticides in Turkey based on pollution potentials Türkiye'de yaygin olarak kullanilan pestisitlerin kirlilik potansiyellerine göre siniflanmasi Ünlü, Kahraman; Sözüdoǧru, Sonay (1997-12-01) Uncontrolled use of agricultural chemicals in intensive agricultural areas of Turkey causes serious soil, surface- and ground-water pollution. Controlled use of agricultural chemicals is of importance for preventing further pollution of these natural resources. The objectives of this paper are to present a screening model that can be used to determine the scientific criteria serving as basis of controlled pesticide use, to classify pesticides according to their pollution potential and, based on this classif...
Estimation of grain characteristics of soils by using cone penetration test (CPT) data Ozan, Cem; Çetin, Kemal Önder; Department of Civil Engineering (2003) Due to lack of soil sampling during a conventional cone penetration testing (CPT), it is necessary to classify soils based on recorded tip and sleeve friction and pore pressure (if available) values. However, currently available soil classification models are based on deterministic and judgemental determination of soil classification boundaries which do not address the uncertainties intristic to the problem. Moreover, size and quality of databases used in the development of these soil classification models ...
A Preliminary study on construction of a high capacity tensiometer and its use in measurement of matrik suction in unsaturated soils Köksalan, Ali Okan; Toker, Nabi Kartal; Department of Civil Engineering (2013) Soil suction is one of the main state parameters that governs unsaturated soil behaviour. Tensiometers are the only type of probe that can measure soil suction directly, but only up to 90 kPa. In the past two decades, a new type of tensiometer with much greater measurement range (up to 2 MPa) has appeared in the literature. The measurement range (i.e. capacity) of a tensiometer is limited by (i) how well it is saturated, and (ii) the air entry value of its porous interface. In this study, the first high cap...
