Wherever industrial development exists, environmental pollution increases day by day. The heavy metals play an important role in soil and environmental pollutions and directly affect the human being lives. In this study, we determine pollutions resulting from heavy metal particles emanating from the brake discs pads of the vehicles on high ways and nearby factories. The field work was carried out in Izmir-Aliaga industrial area. Magnetic susceptibility measurements were done at a long profile crossing the Izmir-Canakkale highway that goes through the study area. Here, we have determined the effect of heavy metals causing pollution in the surroundings. The studies indicate that the average acceptable values of magnetic susceptibility in such areas is about 0-50x10(-5) SI. Here we show that the magnetic susceptibility measurement values obtained along our study profile are about 18 times the acceptable ranges.
