Özet

This study aims to reveal the extent of industrial pollution in the soil in the province of Kocaeli, Turkey. In order to determine the environmental damages caused by Izmit Waste Treatment, Incineration Recycling Corporation (izaydas) which has been operating since 1996, the magnetic sensitivity method has been used to detect the heavy metal concentrations in an area of 1 km(2). The sampling from the region is carried out periodically to observe the trends in pollution with time and to project predictions for the future. The soil profiles of 30 cm deep samples taken from 13 sampling stations at different coordinates that were suspected to be contaminated with heavy metals are investigated by Magnetic Susceptibility (MS) measurements both on site and in the laboratory. The value of magnetic susceptibility is observed to vary between 12.10(-5) and 84.10(-5) SI in the upper layers of the soil samples in on-site measurements. On the other hand, the mass-specific magnetic susceptibility of the samples changes between 2.10(-5) and 202.10(-5) SI in the laboratory measurements. The geochemical analysis is carried out and the heavy metal content consisting of Pb, Cu, Zn, Co, Cd and Ni is determined using the atomic absorption spectrometry method. Additionally, the correlation coefficient is determined from the comparison of magnetic susceptibility with the heavy metal concentrations.
