Lean: Chemical Speciation and Toxicity of Nickel Species in Natural Waters from the Sudbury Area (Canada). Page 1479. The caption for Figure 1 is mislabeled. The corrected caption for Figure 1 is shown below. Figure 1. Percentage of nickel-DOC complexes remaining undissociated as a function of time. Symbols for samples are arranged in increasing order of free plus labile nickel concentrations. The error bars represent 95.5% confidence intervals.
