Monitoring the water contaminants is of utmost importance in resource management. Prediction total dissolved solid (TDS) particularly essential for quality management and planning areas exposed to a mixture pollutants. TDS primarily includes inorganic minerals organic matters, various salts increasing concentration causes esthetic problems. The reflection pollutant burden aquatic system can rem...

estuaries are well known for their potential in removing metal from fresh water to provide micro-nutrients to aquatic life. in the present investigation, we have tried to bring out the metal removal potential of estuaries during accidental spills. for this purpose artificial river water containing high concentration of mn, cu, zn, ni and pb were mixed with sea water at different salinity regime...

the present study was carried out in 2011 to measure concentration of heavy metals chromium and tin in liver and muscle tissue of liza aurata (golden grey mullet) in estuaries of the rivers babolroud, tajan and gorganroud. accordingly, after sampling the target are asandisolating muscle (18samples) and liver (18samples) tissues, they were digested and analyzed using graphite furnace atomic abso...

this study presents data on age structure, sex ratio, growth, length-weight relationships and condition factor of four populations (n=312) of  two alburnoides species, collected in 2005 and 2006 from the tajan river (caspian sea basin), the ghara-chai and jajrud rivers (namak lake basin), and cheshmeh-ali spring (kavir basin) of iran. sex ratio of the fish, in the studied localities, except in ...

salinity and flooding are as two very important factors of soil degradation. they often occur together and cancause severe damage to plants. however, plant response to environmental stresses may vary with growth stage atwhich exposure occurs. a pot study was conducted in 2005-2006 in northern aq qala (northern iran) to studycombine effects of waterlogging and soil salinity at different growth s...
