    Organochlorine pesticides in the sewerage system of Konya-Turkey
    (PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2004) Aydin, ME; Ozcan, S; Sari, S
    In this research, wastewater samples were collected at the general outlet and three different points of the main drainage channel of the sewerage system and analyzed for organochlorine pesticides, such as lindane, mirex, aldrin, heptachlor, methoxychlor, o,p-DDE, p,p-DDD, p,p-DDT and dieldrin. For determination and quantification of the pesticide standards method 6630 was used along with GC/ECD analysis. The recovery rates of solid phase and liquid-liquid extraction methodologies were compared, and changed between 35%-100% for solid phase and 70%-100% for liquid-liquid extractions. In this work, the maximum organochlorine pesticide contents of Konya wastewater varied between 0.02-7.87 mug/L for lindane, 0.13-21.35 mug/L for heptachlor, 0.004-10.13 mug/L for aldrin, <0.0002-1.72 mug/L for dieldrin, <0.01-26.13 mug/L for metboxychlor, <0.0002-1.32 mug/L for mirex, 0.016-4.39 mug/L for o,p-DDE, <0.0002-3.93 mug/L for p,p-DDD, and <0.01-2.28 mug/L for p,p-DDT.

    Polychlorinated biphenyls in wastewater of Konya-Turkey
    (PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2004) Aydin, ME; Sari, S; Ozcan, S; Wichmann, H; Bahadir, M
    In this work wastewater samples were collected from 12 points in a sewerage system, the general outlet of the system and different points of the main drainage channel. USEPA method 8082 was used to analyze the PCB congeners 28, 52, 101, 138, 153 and 180, extracted from wastewater by using solid phase extraction cartridges. Recovery ratios were determined to be between 78% and 93% with the analyses of fortified samples. PCB contents of Konya wastewater varied between 0 and 1.3 mug/L for each congener. Possible sources of PCBs in wastewater and some measures to prevent their discharges are discussed.
