The study was conducted to measure the growth, yield, biomass and heavy metal accumulation in red spinach (Amaranthus dubius) irrigated with treated and untreated industrial effluents, and groundwater. A total of twelve experimental plots, with three treatments (treated, untreated industrial effluents and groundwater) and four replications, were prepared inside the Jananeta Abdul Mannan Hall of Mawlana Bhashani Science and Technology University campus, where red spinach was cultivated and irrigated with 2.5 liter treated, untreated industrial effluents and groundwater in each plot. The content of Zn as 193.28, 182.83, 136.55 and 210.07 ppm, Cd as 0.77, 0.87, 0.93 and 1.03 ppm, Cu as 47.32, 48.93, 57.29 and 73.58 ppm, were recorded in initial soil, soil irrigated with groundwater, treated and untreated industrial effluents, respectively. The content of Zn as 0.00, 0.00 and 0.07 ppm, Cd as 0.004, 0.006 and 0.011 ppm, and Cu as 0.00, 0.02 and 0.68 ppm, were recorded in groundwater, treated and untreated industrial effluent, respectively. The content of Zn as 61.64, 65.30 and 67.67 ppm, Cd as 0.33, 0.52 and 0.57 ppm, Cu as 5.73, 7.79 and 7.95 ppm, were investigated from red spinach plant irrigated with groundwater, treated and untreated industrial effluent, respectively. The levels of cadmium in the red spinach were much higher than that of WHO/ FAO recommended level.
