Corrections

smogandsoot is committed to accuracy. When an error is found in our reference pages, we correct it rather than deleting the content. A substantive correction is made when a fact, figure, or central claim is wrong. Minor typographical errors, grammatical fixes, or formatting adjustments are updated silently and do not receive a published note.

When a substantive correction is made, a note is added to the foot of the article. This note states what was corrected and the date of the change. For example, a correction might read: ‘Correction: This page previously misstated the annual average concentration for particulate matter in Jakarta. The figure was updated on 12 March 2024.’ The original text is amended, but the note provides a transparent record.

Readers can report a suspected error by contacting us. To ensure a swift review, please provide the full web address of the article and quote the exact claim you believe to be incorrect, with details of the correct information if you have them. We aim to investigate and, if required, publish a correction within five working days of verification.

Some facts on smogandsoot require correction not because they were originally wrong, but because the world has changed. This applies particularly to legal standards, policy announcements, or monitoring data. When a government revises a pollutant limit or a new scientific consensus emerges on a health effect, we update the relevant reference pages. Such updates are treated as routine revisions unless our previous text presented the old information as current, in which case a correction note is added.

Our correction system covers all sections, from City Profiles and Pollutant guides to Data and monitoring pages. This process ensures the site remains a reliable resource for understanding pollutants and their impact on cities, primarily in Asia.
