The lines represent nonlinear regression fit of the data to a monoexponential model. The regression estimate (± SE) for organic Hg is = 58.4 ± 25.0 days ( = 0.57). The half-life of inorganic Hg is too long (> 120 days) to be accurately estimated from the present data (i.e., is not significantly different from 0)
