wetlands are often considered sinks for contaminants, and aquatic plants have been shown to play important roles in wetland biogeochemistry through their active and passive circulation of elements. in this research, in order to evaluate the concentration level of heavy metals released by the urban, industrial and agricultural activities at the margin of the rivers flowing into anzali lagoon, as...

We aimed to determine the effects of water level and habitat heterogeneity on gastropod fauna in littoral zone, differentiation functional feeding guilds (FFG) gastropods. Two periods were analyzed: 2012 (low level, LWL) 2013 (high HWL) zone two shallow waterbodies (Sutla backwater, NW Croatia). Waterbody S1, covered with Ceratophyllum demersum, was sampled macrophyte stands, benthal area, whil...

The loss of nitrogen and phosphate fertilizers in agricultural runoff is a global environmental problem, attracting worldwide attention. In the last decades, constructed wetland has been increasingly used for mitigating from runoff, while substrate, plants, structure design remain far clearly understood. this paper, optimum substrates plant species were identified by reviewing their treatment c...

introduction: with increasing of population and the valuable water resource pollutions, a demand has been felt for new and inexpensive methods in order to remediation and improving of water quality. cadmium is a trace element. in low concentration, this heavy metal is harmful to life, and considered as a dangerous pollutant. cadmium leads to pollution and reduction of water quality; sometimes e...

Combined use of in situ passivation and macrophytes is a valuable technology that exerts remarkable effects on aquatic systems. However, the effectiveness ecological functions this combined for macrophytes-dominated eutrophic (MDE) lakes with organophosphorus-controlled internal phosphorus (P) loading were poorly understood. In study, simulation experiments performed to study combination La-mod...
