In this study Sanganer town, Jaipur was
selected as study area. The plants of Lycopersicon esculentum var.? K
21(Tomato) treated with 20 and 30% textile wastewater were analyzed for metal
accumulation, growth and biochemical parameters at per, 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 72.44% while carbohydrate, protein
and nitrogen content showed a reduction of 46.83, 71.65 and 71.65%
respectively. With the increase in waste water treatment the root and shoot
length, root and shoot dry weight and total dry weight were reduced to 50.55,
52.06, 69.93, 72.42, 72.10% respectively. After crop harvesting, the fruit
samples of the plants treated with highest concentration of textile waste
water contained 2.570 mg g-1d.wt. of Zn, 0.800 mg g-1d.wt.
Cu, 1.520 mg g-1d.wt. Cr and 2.010 mg g-1d.wt. Pb.?
