background and objectives: the usepa has suggested faecal enterococci as the primary bacterial indicators. of more importance is their direct correlation with swimmer-associated gastroenteritis in recreation water quality monitoring. in contrast to other seawater bodies with 3.5% salinity, the recreational waters in the southern coast of the caspian sea possess its own salinity (about 1% w/v) a...

Twenty-seven species of Odonata were collected in the present survey in the freshwaters of South-Eastern Iran, Kerman province, in contrast to 11 species that were recorded previously from this region. In this study, 528 specimens were collected from more than 30 sites in Kerman province during 2006-2008. It seems that in this region due to its special biogeographic conditions, species diversit...

many studies since 1977, in the southern coast of caspian sea revealed that the law-setback and low-lying coastal zone have been severely and increasingly impacted by rising sea-level. this rising continued until 1995. the rate of rising was nearly 13cm per year in this period (1977-1995). the general concept of setback determination is tended to introduce a buffer area between human activities...

conclusions in conclusion, toxicological studies showed that, although contamination level in caspian sea fishes was relatively low, the present status might pose a risk about food chain contamination. results the review showed that nine studies were recorded in databases about pesticide residues in caspian sea fish tissues. these studies reported that there is limited evidence of organochlorin...

nowadays, a noticeable part of the relations among the states turn around the environment protection. therefore, the right for ever-creasing use of the existing resources of this inland sea cannot be exclusive to any caspian state and the aftermath involves all countries of this basin. in this respect, agreement on political border and boundaries with the caspian sea?s ecosystem is a difficult ...

in this research, the correlation between precipitation change in southern coasts of caspian sea and variability of sea level pressure have been analyzed by using environmental to circulation approach at time period 1339- 1383. in this respect, we make use of daily precipitation data of the 12 synoptic stations of studied area at surface data base section and prepare the time series matrix of p...
