Comparative Phytoremediation Potential of Eichhornia crassipes, Lemna minor, and Pistia stratiotes in Two Treatment Facilities in Cluj County, Romania

Phytoremediation is an effective method used to control the accumulation of certain contaminants found in industrial or city wastewater. Among species with high efficacy are Eichhornia crassipes (water hyacinth), Lemna minor (common duckweed), and Pistia stratiotes lettuce). In this study, application these context two municipal wastewater treatment facilities Cluj County, Romania, evaluated. To determine bioaccumulation, we measured content nitrogen (ammoniacal nitrogen, nitrites, nitrates), phosphorous, iron, chromium before after addition plant material effluent treated The results showed that E. crassipes, L. minor, P. presented phytoremediation yields for common pollutants one week contact, as 99–100% ammoniacal 95% 96% 94% chromium. However, remediation capacity nitrate nitrite was less significant.
