Abstract :We aim to quantify heavy metals in tea powders insert ignore into journalissuearticles values(packed and used);, tea waste disposal sites and in the soil away from the site of disposal and to isolate the bacteria from both the soil sample. Atomic Absorption Spectrometer insert ignore into journalissuearticles values(AAS); analysis revealed chromium in the samples collected from Thanjavur insert ignore into journalissuearticles values(0.12 mg/kg); and Tiruchirappalli insert ignore into journalissuearticles values(4.77 mg/kg);. The quantity of Copper was between 0.14 mg/kg and 0.97 mg/kg Namakkal and Erode samples respectively. We also found trace levels of other heavy metals. The spatial map distribution patterns of selected Physico-chemical parameters like pH, EC, Alkalinity, Total carbon in the disposal sites were presented. Some of the metal-intolerant strains isolated from the disposal sites became resistant. Further investigation would unravel the possible mechanism behind Chromium reduction by the selected isolates.
