Abstract

The present investigation characterizes tannery effluents by determining WATER quality parameters and some selected trace METALlic constituents in order to measure the magnitude of environmental POLLUTION. Effluents and sediments have also been used to isolate chromium-resistant bacteria, collected from Hazaribagh area, Dhaka, claimed to be increasing Cr (VI) -enriched environments, and utilized to reduce Cr (VI). The pH, TDS, DO, and EC values of all investigated samples have been within the range of 4.35 to 9.74, 290 to 9, 200 mg/L, 1.5 to 4.90 mg/L, and 587 to 19, 000 ms/cm, respectively. The concentrations of trace METALlic constituents have been determined by means of Atomic Absorption Spectrophotometer (AAS), giving the following ranges: Cr: 14.282 to 6, 769.554 mg/L; Cd: 1.546 to 2.214 mg/L; Pb: 18.808 to 32.026 mg/L; Cu: 1.522 to 2.578 mg/L; Zn: 0.682 to 8.688 mg/L; Fe: 1.37 to 108.556 mg/L; and Mn: 3.494 to 17.17 mg/L. The order of trace METALlic constituents in the effluent samples was Cr>Fe>Pb>Mn>Zn>Cd>Cu. The WATER quality parameters and METALlic constituents’ concentration were higher than that of standard permissible limits in all the examined samples. The average number of Cr (VI) -resistant bacteria in the sediment samples with glucose (0.5%, w/v) supplementation was 2.35×103 CFU/gm at 24h. One of the representative isolate was able to tolerate up to 400 mg/L of K2Cr2O7 as Cr (VI). The bacteria, isolated in the present study, can be used as eco-friendly biological agents for the remediation and/or detoxification of chromium (Cr) POLLUTION from the chromium contaminated environments.
