the effects of industrial textile water(effluent water,ew) on soil, water and plant was investigated in this research. for conducting this research major important textile factory were selected and sampling was done in 2 stages and in 2 years. in each district and the control field (soil not irrigation with effluent water) the soils from 0-30 cm depth and plants were sampled in three replicates...

in this study, water samples were collected from 10 thermal and non-thermal springs of mahalat setting during four periods in 2011. the discharge rates of these springs vary from 2 l/s to 45 l/s and their temperature range from an average minimum of 18oc to maximum 47oc. spring water is high in so4-cl and this is related to gypsum dissolution. correlation coefficient, principal component analys...

Water and sediment samples were collected from six different stations, located along the Nil River between February and June 2015. Concentrations of cadmium, lead, zinc, and copper were determined. The extent of the sediment pollution was assessed, using the multiple pollution indices, namely contamination factor (CF), pollution load index (PLI), and the geoaccumulation index (Igeo). The result...
