Pollutants are among the effective disrupters of the environment. Among them, heavy metals are inherently non degradable with undesirable physiological effects on organisms even at low concentrations. Nowadays, increasing soil pollution with heavy metals and its impact on human health due to increased industrial and urban activities is one of the serious concerns of many communities. Therefore, measurement and monitoring the concentration of heavy metals in different regions, especially in areas with potential risk of contamination, is necessary. In residential areas, excessive accumulation of heavy metals in the surface soil can directly threat the health of residents, especially children, through ingestion, inhalation and dermal contacts. Soil contamination with Pb, Cd and Zn is not limited to large cities. The purpose of this study was to investigate effects of the human activities on soil pollution to heavy metals Pb, Cd and Zn in Babel province of Iraq. The geographic location of the sampling sites was recorded by GPS. Using random sampling method, 16 samples of surface soil (0-5 cm) and 11 samples from depth of 50- 60 centimeters were collected from different regions of Babel. The total and bioavailable as well as the stomach solution extractable concentration of the heavy metals were measured and the intake risk of these metals through ingestion, inhalation and dermal contact were assessed for adults and children. Statistical analysis of data including variance analysis were performed using a completely randomized design, and mean comparison and the analysis of the main components were done by SAS 9 software. The results indicated that the concentration of heavy metals in the soils of urban and rural areas of Babel compared to the WHO standards set for the parks, dirt roads main roads, and green spaces of the villages are in the acceptable range. The results indicated that the highest total concentrations of Pb, Cd and Zn are in Bab Al-Mashhad region. However, the concentration of Pb, Cd and Zn varied among different regions. The metal emission sources seemed the same and affected by human activities caused by traffic and industrial areas. The results showed that soil contamination by lead can be due to human activity in the urban traort sector. The concentration of cadmium in the soil of all studied sites was less than the detection limit of the atomic absorption device. The results show the potential harmful effects on the health of children, but it should be emphasized that the use of heavy metal concentrations to carry out risk assessments usually overestimates the true health risks. In the study the health risk, (HQ) was in an acceptable level either for adults or children. Key words : Heavy Metals, Dangerous Diseases, Health Risks, Urban Traort.
