Background: Gavkhooni marsh is one of the most important marshes in Iran. In the recent years, natural conditions of this marsh have been affected by agricultural and industrial activities in Zayandehrood river catchment areas. This research was carried out in 2006 to assess some chemical parameters and the heavy metals concentration in water, soil, and plants in the area and to compare the results to the standard values and also with the previous researches conducted in the years of 2002 and 2004.   Methods: The samples were taken and transferred to the water laboratory of Isfahan University of Medical Sciences. The water samples were analyzed for pH, chloride, EC, alkalinity, heavy metals. Soil was sampled from depth of 5 cm (as surface sample) and 10 cm (as depth samples).  Both soil and plant samples were digested with H2O2 and H2SO4 after drying.  The digested samples were analyzed for the heavy metals by the Atomic Adsorption on Standard Methods, part: 303A.   Findings: The findings indicated that the average concentration of Cd, Cr, Cu, Mn, Ni, Pb, and Zn in the water samples were 0.73, 0.054, 0.76, 0.058, 0.48, 1.14, and 0.075 mg/L, respectively. These findings were higher than the standard values in drinking water and water for agricultural use. The values for EC and chloride indicated extreme pollution of the marsh. The continuing of this trend in the future may cause accumulation of the pollutants that could affect the marsh and destruct it.   Conclusion: Comparing the results of researches in the years 2002 and 2004 indicated increasing process of the pollutants aggregation in the marsh’s water and soil. However, the evaluation of the achieved results from this research and also from 2002 and 2004 indicated that some parameters in water and soil were decreased compared to the measured values in the previous years due to suitable rainfall in 2006.   Key Words: Gavkhooni Marsh, Heavy Metals, Zayandehrood River
