    Effect of warfare waste on soil: a case study of Gallipoli Peninsula (Turkey)
    (Inderscience Enterprises Ltd, 2004) Baba, A; Deniz, O
    Gallipoli is a small town on the European side of the Dardanelles Strait, in Turkey. More than 450 000 soldiers gave their lives on the Gallipoli Peninsula (Gallipoli Campaign) over a nine-month period during World War I. In that war, many naval and landing bombs were exploded. The ingredients of these bombs may cause heavy metal contamination in soils. An environmental geochemical investigation has been carried out around Gallipoli Peninsula in order to determine the extent of chemical pollution in the soil. The preliminary data reveal that soils in the area are, in general, not contaminated. The concentrations of many heavy metals, such as arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr), cobalt (Co), manganese (Mn), nickel (Ni), lead (Pb), strontium (Sr), vanadium (V) and zinc (Zn) are in the range of those of average agricultural soils. These low concentrations are explained by the good leaching characteristics of Oligocene-Miocene rocks, Pleistocene terrace material, alluvium sandy-silty soils, and surface run-off.

    The impact of an open waste disposal site on soil and groundwater pollution
    (Inderscience Enterprises Ltd, 2004) Baba, A; Kavdir, Y; Deniz, O
    A study has been carried out of a waste disposal site, located in the valley of a small creek, 3 km south of Canakkale city centre. The surface area of the site was around 10000 square metres, and the total amount of waste deposited at the site since 1990 was approximately 100000 tons. The major risks of the dump are its closeness to the university campus area to the south, the airport to the north, and residential areas encroaching towards the dump site. The nuisance caused by odour is high. The waste pile emplaced at the head of the tributary stream has caused channelling of the leachate to the creek, which is eventually washed towards the agricultural fields. The field investigation included surface geological, hydrogeochemical and geochemical studies. Water samples were collected at 11 points. Three observation wells were dug in front of the open waste disposal site. Soil samples from these observation wells were collected at 30, 70 and 150 cm depths, and some heavy metals were analysed. The concentrations of lead, copper and zinc in soil at the depth of 150 cm decreased with distance from the waste disposal site. Hydrogeochemical data analysis gave similar results.
