Abstract: The toxic effect of metal ions like chromium (Cr3+), cobalt (Co2+), nickel (Ni2+), copper (Cu2+), cadmium (Cd2+) and lead (Pb2+) on biochemical oxygen demand (BOD) of synthetic wastewater samples has been studied at different temperatures i.e., 15°C, 20°C, 25°C and 30°C. Experiments were conducted for BOD exertion in presence (10 ppm of each metal ion) and in the absence of metal ions at different temperatures. Transition metal ions like Cr3+, Co2+, Ni2+ and Cu2+ show an increase in relative percentage inhibition with increasing atomic number. BOD inhibition in presence of Cd2+ and Pb2+ is relatively large. The metal ions under study are found to be highly toxic to microbes.
