Correction: Influences on and patterns in total gaseous mercury (TGM) at Harwell, England.

There is an error in the following sentence in the article abstract: “This is comparable to other northern hemisphere studies, but on average 0.5 ng m 3 higher than at its sister monitoring station at Auchencorth Moss, Scotland, but 14% lower than that found in a similar study at the same location of 1.68 ng m 3 in 1995/6”. The corrected sentence should read: “This is comparable to other northern hemisphere studies, but on average 0.05 ng m 3 higher than at its sister monitoring station at Auchencorth Moss, Scotland, but 14% lower than that found in a similar study at the same location of 1.68 ng m 3 in 1995/6”. The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
