    Accumulation of Micropollutants in Aqueous Media and Sediment, A Risk Assessment for Konya Main Drainage Channel, Turkey
    (Springer International Publishing Ag, 2019) Aydin, Mehmet Emin; Aydin, Senar; Beduk, Fatma; Ulvi, Arzu; Bahadir, Mufit
    Human activities increase types and numbers of synthetic pollutants and their byproducts in the course of time. Synthetic Organic Chemicals (SOCs), so called micropollutants, present in very low concentrations in aquatic ecosystem, but likely accumulate in animal and human tissues and cells because of fat solubility. These persistent micropollutants have toxic effects in very low concentrations and resistant to biodegradation. SOCs can be adsorbed to sediments in surface water sources, so sediments have an important role in the accumulation of water contaminants. In the course of time, sediments become source of new contamination for aqueous media. In this study, it is aimed to determine concentration of two groups of SOCs; organochlorine pesticides (OCPs) and organophosphorous pesticides (OPPs) in wastewater, surface sediment and excavated sediment samples taken from Konya Main Drainage Channel (MDC) which takes the effluents of Konya Wastewater Treatment Plant and transports the treated wastewater to Salt Lake.

    PESTICIDE POLLUTION IN SOIL AND WHEAT: RISK ASSESSMENT OF CONTAMINATED FOOD CONSUMPTION
    (Parlar Scientific Publications (P S P), 2017) Beduk, Fatma; Aydin, Mehmet Emin; Aydin, Senar; Tekinay, Arzu; Bahadir, Mufit
    In this study, organochlorine pesticides (OCPs) and organophosphorus pesticides (OPPs) contamination of wheat cultivated in Konya region and soils of this region were determined. Health risk caused by the consumption of pesticide contaminated wheat was assessed. Totally, 30 soil samples and 21 wheat samples taken from the field and trade center were analyzed for OCPs (alpha-HCH, beta-HCH, gamma-HCH, delta-HCH, aldrin, dieldrin, heptachlor, heptachlor epoxide, endosulfan I, endosulfan II, endosulfan sulfate, p,p'-DDE, p,p'-DDD, p,p'-DDT, endrin, endrin aldehyde, endrin ketone, methoxychlor) and OPPs (malathion, parathion, methyl-parathion, chlorpyrifos, diazinon). Determinations of OCPs and OPPs were carried out with a GC/MSD (GC, Agilent 6890 N, MSD, Agilent 5973). Maximum concentrations of OCPs in soil samples were found for Sigma HCHs (alpha-HCH, beta-HCH, gamma-HCH, delta-HCH) and Sigma endosulfan (endosulfan I, endosulfan II, endosulfan sulfate) in the range of 8.74 - 71.8 ng g(-1) and 1.99 - 112 ng g(-1), respectively. Malathion and chlorpyrifos were the predominant OPPs in soil and wheat samples. Maximum concentrations of malathion and chlorpyrifos in soil samples were 222 ng g(-1) and 556 ng g(-1), respectively. Maximum total OCPs and total OPPs in the grain were 2.32 mu g g(-1) and 15.4 mu g g(-1), respectively. Sigma DDT was found in the range of 20 60 ng g(-1) in grain samples. Trade center samples exceeded maximum residue limits (MRL) of Turkish Food Codex (TFC) given for beta-HCH, gamma-HCH, Sigma HCH, dieldrin and chlorpyrifos, and field samples exceeded MRL given for a-HCH, beta-HCH, Sigma HCH, Sigma endosulfan, Sigma heptachlor, and all OPP compounds. There is an acute and chronic consumer health risk due to the consumption of pesticide contaminated wheat, on the basis of aHI and HQ calculation. Besides, prohibited pesticides are obviously still being used in the area.

    WASTEWATER REUSE IN MIDDLE EAST COUNTRIES - A REVIEW OF PROSPECTS AND CHALLENGES
    (Parlar Scientific Publications (P S P), 2016) Bahadir, Mufit; Aydin, Mehmet Emin; Aydin, Senar; Beduk, Fatma; Batarseh, Mufeed
    The Middle East Region is one of the driest regions in the world. Water shortage in most of the region has led to wastewater reuse practices. While this source includes valuable nutrients essential for plants, it also contains various environmental contaminants, which can threat both human health and agricultural sustainability. Uncontrolled applications for long term result in soil deterioration, contaminated agricultural products, and sanitary problems. In many Middle East Countries, wastewater treatment plants are lacking. Domestic wastewaters are sometimes contaminated with uncontrolled industrial discharges. Wastewater quality and soil safety for wastewater application are often neglected. For sustainable use of wastewater in the region, there is a serious need for regulations, monitoring of wastewater, soil and product quality, and public awareness about possible adverse effects of untreated wastewater. In this review, the authors aimed to give an overview about the state-of-the-art of wastewater reuse in particular for irrigation purposes in Turkey and the Arab Countries in the Middle East. The different origins of wastewater discharge that are manifold in the Middle East Region, e.g. domestic, touristic, industrial, and agricultural drainage, pollutants identified in the wastewater, and R&D efforts made for a pollution inventory, removal of pollutants through wastewater treatment before use, and the fate and behaviour of the residual pollutants in agro-ecosystems during irrigation with wastewater are reported.
