Correction to: British Journal of Cancer (2015) 112, 1603–1612. doi:10.1038/bjc.2015.108

After the publication of ‘Benzene exposure and risk of lymphohaematopoietic cancers in 25 000 offshore oil industry workers’, the author would like to make the following corrections:

When referring to work by other researchers we used the symbol ‘<’ incorrectly. The expression ‘<0.2 p.p.m.’ (reading: ‘less than 0.2 p.p.m.’) should have been expressed as ‘down to 0.2 p.p.m.’

This error occurs at two places in the article:

(1) Introduction, p. 1604, 1st column, 4th paragraph: ‘Some reports have suggested that benzene may be leukaemogenic and haematotoxic at low concentrations (<10 p.p.m. and <0.2 p.p.m., respectively).’

(2) Discussion, p. 1610, 2nd column, 3rd paragraph: ‘Interestingly, the observed risk patterns for MM and CLL correspond to the finding of benzene toxicity to B-cells in the bone marrow at occupational benzene exposure <0.2 p.p.m.’.
