Abstract

A microbial fuel cell (MFC)-based biosensor can be used to detect the water toxicity. In this study, the solitary and joint biotoxicities of heavy metal ions (Cu2+, Ni2+, Cd2+) and acephate were investigated using single-chamber MFC. The results showed that all the contaminants could individually inhibit the electricity production of MFC, and the toxicity order of these three metals was Cd2+>Ni2+>Cu2+. The concentration-response curves for Cu2+, Ni2+ and acephate were well fitted linearly while the curve for Cd2+ was well fitted by an exponential function. The joint-biotoxicity results of Cd2+-Ni2+ and Cu2+-acephate were as follows: the toxic effect of Cu2+ and Ni2+ was synergistic. The existence of Cu2+ had antagonism with acephate at low concentrations, which could reduce the biotoxicity, while their toxic effect on MFC became synergistic at high concentrations. This study could provide some basic data for water quality monitoring using MFC.
