Background : Ramsar, a city in Mazandaran province, is located between Tonekabon and Chaboksar. It covers an area of about 30 Km2 overlying alluvium and coastal deposits of Quaternary Period. Shallow depth of water table within the area increases the chance of contamination through seepage of waste water from septic wells and agriculture. Materials and methods : We have examined 31 samples to d...
Some areas in Ramsar, a northern city of IRAN, have the most natural radiation level in the world which is due to high concentration of 226Ra and its daughter products specially 222Rn and therefore these regions have been interested for radiation related investigations. The aim of this study also has been to evaluate public exposure in such areas in Ramsar, in order to obtain up to date informa...
Assessment of the Mutagenic Potential of Skadar Lake Sediments Using the Salmonella Microsomal Assay
Organic extracts of sediments from Skadar Lake (National park and protected RAMSAR site) were investigated for their mutagenic potential using Salmonella typhimurium TA98 and TA100 strains in the presence and absence of metabolic activation. Five different concentrations of sediment extracts from five different sampling sites were assayed, and mutagenic results were obtained for both strains. T...
The largest fraction of the natural radiation exposure we receive comes from a radioactive gas, radon and its decay products (nearly 50%). The radon gas can enter to the body via respiring, drinking and eating and caused damage to respiratory and digestion systems. Also radium-226 is widely distributed in the environment. When a person ingests radium, this element deposits in bones and cause to...
Harike wetland was declared a Ramsar site in 1990. It is located at the confluence of two major rivers of Indus rivers system, the Beas and the Sutlej, but was never explored extensively for its existing fish biodiversity. Earlier only 27 fish species of commercial value were reported from the wetland. Acknowledging its importance for rich diversity fish assemblages in seven different reaches o...
