AB  - An innovative indicator for toxicity detection based on microbial fuel cells, 
      average current inhibition rate (ACIR) was proposed. It was applied to the 
      toxicity evaluation of three typical specific pollutants in petrochemical 
      wastewater including copper(II), 2,4-dichlorophenol (2,4-DCP) and pyridine. ACIR 
      which considered the entire process of toxic effects was proved to be more 
      sensitive and wide-ranging than the conventional indicators. The linear detection 
      ranges were 0.3-100 mg/L of copper(II), 0.4-1000 mg/L of 2,4-DCP, and 
      0.1-1000 mg/L of pyridine. The median effective concentrations of the three 
      toxicants were 34.32, 36.18 and above 1000 mg/L, respectively. By contrast, using 
      a conventional indicator such as the voltage inhibition rate, the calculation 
      results consistently change with the exposure time. Based on the response time, 
      the toxicity will be difficult to distinguish under high concentrations. An 
      analysis of the microbial community in anode chamber showed that electrogenic 
      bacteria such as Geobacter and Arcobacter significantly decreased with 2,4-DCP 
      and pyridine under all tested concentrations. A principal component analysis was 
      conducted, the results of which showed that the microbial community shifted from 
      left to right with the increase concentration of copper(II) and 2,4-DCP. An 
      increase of ACIR was noticed to be in accordance with the reduction of 
      electrogenic bacteria.
