Description based on: Vol 1, no 1, published in 1971?; title from table of contents page (publisher’s website, viewed May 15, 2017).
Latest issue consulted: Vol 26, no 2 (November/December 2016) (viewed May 16, 2017).
Some sources describe the print version of this publication as a merger of: Clean air journal (Johannesburg) and: Clean air journal (Pretoria). Based on correspondence with editors, and on page images bearing different ISSN within the same issue, it seems much more likely that the publication was erroneously registered as two publications due to appearing in both English in Afrikaans. It is possible, though not certain, that National Association for Clean Air (South Africa)’s move to a Halfway House headquarters might have coincided with the "merger."
