The original publication of this article (doi: 10.1007/s11270-020-04842-1) contained the following errors:

  1. (1)

    In page 4, section 2.2 “Test Species and Stock Culture,” the units of the numbers “1.93 (1.63–2.22) μg/L” and “0.81 (0.71–0.92) μg/L” were wrong. The units should have been “mg/L” instead of “μg/L.”

  2. (2)

    In Online Resource 2, the last sentence of the second paragraph in the Results section “The estimated values (95% confidence intervals) of dissolved-nickel EC50 were 1.93 (1.63–2.22) μg/L for the moderately hard water culture and 0.81 (0.71–0.92) μg/L for the soft water culture” should be read as “The estimated values (95% confidence intervals) of dissolved-nickel EC50 were 1.93 (1.63–2.22) mg/L for the moderately hard water culture and 0.81 (0.71–0.92) mg/L for the soft water culture.”

  3. (3)

    In Online Resources 2 and 4, the unit was incorrectly written in the x-axis labels in Fig. 1. The unit should have been “mg/L” instead of “μg/L.” The correct figures are reproduced on the following pages.

The authors apologize for the errors.
