Some values presented in the text for the mass transfer coefficient were in error, missing a minus sign before the exponent. All values in Table 1 were correct. The corrected values are shown below.

In the Water impact statement on page 467, the value of 2.03 × 10³ m h⁻¹ should read 2.03 × 10⁻³ m h⁻¹, and the value of 3.95 × 10³ m h⁻¹ should read 3.95 × 10⁻³ m h⁻¹.

In the Results and discussion section on page 470, the value of 2.03 × 10³ m h⁻¹ should read 2.03 × 10⁻³ m h⁻¹; the value of 3.95 × 10³ m h⁻¹ should read 3.95 × 10⁻³ m h⁻¹; the value of 5.75 × 10³ m h⁻¹ should read 5.75 × 10⁻³ m h⁻¹; the value of 3.50 × 10³ m h⁻¹ should read 3.50 × 10⁻³ m h⁻¹; and the value of 2.46 × 10³ m h⁻¹ should read 2.46 × 10⁻³ m h⁻¹.

In the Conclusion section on page 472, the value of 2.03 × 10³ m h⁻¹ should read 2.03 × 10⁻³ m h⁻¹, and the value of 1.18 × 10² m h⁻¹ should read 3.95 × 10⁻³ m h⁻¹.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
