The luminous inhibition ratio and the equivalent concentration of HgCl2 in different sediments. The inhibition rates and equivalent concentrations of HgCl2 were shown in the figure. The inhibition rates were calculated by the negative control. The equivalent concentrations of HgCl2 were calculated according to the standard curve. The symbol A3 (B3, C3): the sampling site near the leak point; MED: control site in Jiaozhou Bay; SLR: control site outside of Jiaozhou Bay
