Abstract

The use of oil can be harmful for the environment. Oil spills are a common phenomenon, owing to the excess usage of oil and oil products in our daily routine. In the last few years people worldwide have taken in the importance of the risk of oil leaks and the harm caused to the environment due to toxic pollution. Soil is one of the basic natural, not renewable and wealth resource, which preserves living on our planet. Soil pollution with oil is a major problem that exists in Cyprus and other advanced industrial countries. Soil remediation is an emergency for the following years. The aim of this thesis was to illustrate the change at the behavior of each oil spill which had absorbed by soil after an accident and the change of HCs’ imprint included in the oil, over the time. Five types of oil were used and analyzed in the GC at specific time points. Analysis of the samples in GC was done in five phases (time points), which were assigned to the 1st, 14th, 38th, 69th and 101st day. In total, 101 days were required to carry out the experiment. In specific, a soil sample from Nicosia was taken and polluted with 5 different types of oil, due to the experimental part of this thesis. These types are Biodiesel, Diesel Fuel, Heating Diesel, Kerosene and Fuel Oil. At first, a physicochemical analysis was done, followed by the soil-oil mixture samples’ analysis in GC with flame ionization detector (GC-FID). The specific soil contained large amounts of organic matter. The moisture of the dried soil was 3.23%. The pH of the soil was 6.85 and so it can be characterized as neutral or slightly acidic.
