This work was carried out to evaluate the accumulation rates of some heavy metals in new reclaimed soils (sand and loamy, clay loamy texture) in El-Bostan and El-Nubaria villages. Soil samples were taken from El-Nubaria and El-Bostan villages with depth of 0-30 cm and 30-60 cm and cultivation periods 5 years,, 10 years and 20 years. The results indicated: 1. Highly significant differences were found between the concentration contents of the studied heavy metals Pb, Cd, Co, and Ni in the low lime contents soils and high lime contents one. 2. Highly significant differences were found between the accumulation of heavy metals Pb, Cd, Co and Ni and the cultivation period. 3. Highly significant correlation was found between heavy metals accumulation (total and available) in the soils and concentration of these elements in plant grown thereon. 4. Statistical analyses showed that heavy metals accumulation in both low lime contents and high lime contents one due to increasing the accumulation of these elements in plants grown thereon. 5. A highly significant correlation between the concentration of the studied elements in soils and plants grown thereon and the cultivation period. Therefore, heavy metals accumulation in plants related to increasing heavy metals content in the soils which plants grown thereon (maize, wheat plants) and hence may adversely affect the environment and human health. Therefore, to protect the environment and public health we have to keep soil and plants away of pollution by heavy metals and minimizing mineral fertilizers consumption as a source of heavy metals accumulation in soils and plants. Finally, it may be conducted that more studies should be carried out in various locations and vast areas to monitor and control the status and avoiding the probability of plant and soil pollution in Egypt, as this study just not more a preliminary study.
