“…Finally, sedimentation rate is determined to see how the lake has changed during the past centuries. A number of traditional and modern methods, such as hydrographic maps [25] and isotope tracing, are used to assess sedimentation dating [26]. Detecting isotopes using 210 Pb was chosen as the main procedure to achieve the research goals.…”

Metal contents and enrichment factors of ten major trace metals, along with total organic matter, were studied using a 50-cm-long sediment core from Zariwar Lake in Iran. The source of elements (Fe, V, Co, Cd, Al, Cu, Zn, Ni, Cr and Mn) was investigated by chemical partitioning technique as well as cluster analysis. Results of partitioning revealed the anthropogenic portion of metals (%) to be: Zn > Cu > V > Ni > Mn > Cd > Co > Cr. Cluster analysis classified all elements into clusters A and B. The presence of Fe and Al as earth indices in both clusters indicated that all investigated elements likely originate from the lithogenic sources to some extent. Results obtained from the geochemical accumulation index, pollution index, enrichment factor and Hakanson index showed that the sediments were not contaminated and did not exhibit ecological risk. Negligible levels of pollution were seen in terms of Ni and Mn contents. Average sedimentation rate was about 5.6 mm/year according to 210 Pb activity through the depth of the core, which is about 5.5 times greater than the ones reported in other freshwater lakes. Considering the lake being small, this increasing trend in sedimentation rate may create short phases of lake sedimentation and degrade the aesthetic quality of this aquatic environment.

Although Iran is of founders of the Ramsar Convention, there is no comprehensive information available in the country on the status of wetlands in the past or at present. There is also no specific guideline for assessing the status of wetlands in the basin of the Caspian Sea as an ecosystem with unique ecological features. The main aim of this study was to develop a new procedure called "Caspian Rapid Assessment Method" (CRAM) for assessment of wetlands at southern fringe of the Caspian Sea. To this end, 16 rapid assessment methods analyzed by US EPA in 2003 were reviewed to provide an inventory of rapid assessment indices. Excluding less important indices, the inventory was short-listed based on Delphi panelists' consensus. The CRAM was developed with 6 main criteria and 12 sub-criteria. The modified method was used to assess three important wetlands of Anzali, Boojagh and Miyankaleh at the southern border of the Caspian Sea. According to the obtained results, the highest score of 60 was assigned to the Anzali Wetland. Obtaining the scores of 56 and 47, Miyankaleh and Boojagh wetlands were ranked in the next priorities, respectively. At final stage, the accuracy of CRAM prioritization values was confirmed using the Friedman test. All of the wetlands were classified into category II, which indicates destroyed wetlands with rehabilitation potentials. In recent years, serious threats have deteriorated the wetlands from class III (normal condition) to the class II.
