Effect of Textile Waste Water on Vigna unguiculata var. RC-101(cow pea) in a Pot Experiment with Reference of Heavy Metal Bioaccumulation
Abstract: The plants of Vigna unguiculata var. RC-101 (cow pea) treated with different level of waste water and analyzed for metal accumulation, growth and biochemical parameters at pre, peak and post flowering stages. Findings of the study revealed that chlorophyll content was most severely affected with the increase in metal concentration. Total chlorophyll content showed a reduction of 56.55percent while carbohydrate, protein and nitrogen content showed a reduction of 47.83 percent, 55.31 percent and 55.40 percent respectively. With the increase in wastewater treatment the root and shoot length, root and shoot dry weight were reduced to 45.43 percent, 29.48 percent, 61.97 percent, 53.11 percent respectively. After crop harvesting, the fruit samples of the plants treated with highest concentration of textile waste (50 percent waste water mixed with 50 percent of distilled water) water contained 5.257 mg g -1 d. wt. of Zn, 2.518 mg g -1 d. wt. Cu, 1.276 mg g -1 d. wt. Ni, 1.895 mg g -1 d. wt. Cd, 4.893 mg -1 d. wt. Cr, 1.897 mg g -1 d. wt. Pb and 1.854 mg g -1 d. wt. Co.
