Abstract

We aim
to quantify heavy metals in tea powders (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 (AAS)
analysis revealed chromium in the samples collected from Thanjavur (0.12 mg/kg)
and Tiruchirappalli (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.

Keywords
