Soil contamination is one of the most important factors influencing the quality of agricultural products. Usage of heavy farm equipment, the land drainage, application of inadequate agrochemicals, emissions from mining, metallurgical, chemical, coal power plants and transport, all generate a number of undesired substances (nitric and sulfur oxides, PAHs, heavy metals, pesticides), which after deposition in soil may influence crop quality. Thus, the input of these contaminants into the environment should be carefully monitored. This paper presents the data obtained for organ chlorinated pesticides, their residues, PCB and chlorine benzenes in the soil, tomato plants and fruits of agricultural areas. The samples were taken in March 2014 in the Dukagjini Part, in the village near the Peja and we collect 12 samples. The analysis of the organ chlorinated pesticides was performed by gas chromatography technique using an electron capture detector (GC/ECD). Optima-5 (low/mid polarity,) capillary column was used for isolation and determination of organ chlorinated pesticides. Interpretation of data was performed using cluster analyze models. Relatively low concentrations of organ chlorinated pesticides and their metabolites were found in the studied samples. Two were the main groups, DDTs and HCHs. The presence of organ chlorinated pesticides residues is probably resulting from their previous uses for agricultural purposes. PCB 52 was the main congener found in soil samples and hexachlorobenzene was the main compound for chlorinated benzene compounds.
