Abstract
Siahkal area (15 km southwest of Lahijan), is located  in SE of  Rasht 1:100000 geological map. According to the geochemical samples, collected in the coverage of this map, concentration of some elements like Mn, Co, Ni and Pb, have been  detected to be higher than  normal values, creating a series of symptoms and environmental pollution. For example, they can result in some malformations in plants  decreasing the root and stem diameter, shortening, or a change in the color of  leaf and stem of plants and trees. Environmental pollution may give rise to diseases in human beings such as sensitivity of respiratory problems, and even cancer.  According to the Siahkal 1:50000 map, in some regions such as : Paeen gavaber, Jeer gavaber, up and down  Zarkooti,  some elements like Mn, Co, Ni and Pb, show high concentrations than the standard values.
