摘要

In present study, pollution load, ecotoxicological impact, and treatability potential of aquatic plants, viz. Eichhornia crassipes, Pistia stratiotes, and Spirodela polyrhiza evaluated for textile effluent in Jaipur region, Rajasthan, India. Wastewater quality of textile effluent exhibits high pollution load (mg/L) in terms of total suspended solids (TSS, 1986), biological oxygen demand (BOD, 72), chemical oxygen demand (COD, 2851), and metal contamination with concentration of Zn (6.41) > Cu (4.66) > Fe (4.61), Pb (4.58) > Cr (3.64) > Ni (3.53) > Cd (1.89). Evaluation of the Water Quality Index (WQI), Heavy Metal Pollution Index (HMPI), and Heavy Metal Evaluation Index (HMEI) reveals that textile effluent has detrimental effects on both water and soil quality. Additionally, evaluation with using geographical information systems (GIS) showed differences in water quality at different locations, and principal component analysis (PCA) indicated that soil quality varied significantly, with changes of 79.74% and 87.48% (p < 0.05). Luxuriant and fast growth of the selected aquatic plants, viz. Eichhornia crassipes, Pistia stratiotes, and Spirodela polyrhiza in diluted textile effluent and their potential for reducing pollution load demonstrate their feasibility to be use in developing low cost and sustainable technique for wastewater treatment. However, maximum reduction in pollution load observed in textile effluent treated with E. crassipes in terms of removal of TSS (31%), BOD (38%), and COD (41%). Present study provides new insights in integrating advanced techniques for ecotoxicological assessment using GIS and PCA and developing sustainable methods for treatment of textile effluent by exploring efficient aquatic plants.
