The AQHIs are reported on a scale of 1 to 10 and 10+ and are grouped into five AQHI health risk categories with health advice provided.  This is particularly useful for children, the elderly and those with heart or respiratory illnesses who need to take precautions when the health risk levels are high.  The AQHI forecast also advises the public before the onset of high health risk categories due to pollution episodes.\n\nPlease refer to the [thematic page of AQHI](http://www.aqhi.gov.hk/en) for more information.\n\nThe above external links lead to a collection of CSV files containing past hourly AQHI data since December 2013.","url":"https://www.aqhi.gov.hk/epd/ddata/html/history/2016/201607_ChT.csv","format":"CSV","language":"zh-Hant","updated":"2025-08-04T16:41:09.380027","isApi":"N","upstreamDocumentation":[]}],"sourceUrl":"https://data.gov.hk/en-data/api/3/action/package_show?id=hk-epd-airteam-past-record-of-air-quality-health-index-tc","updated":"2026-07-09T16:34:19.935975","retrievedAt":"2026-10-20T22:31:00.105Z","license":"","licenseUrl":"","updateFrequency":"Every Six Months","upstreamDocumentation":[{"title":"Data dictionary","url":"http://www.aqhi.gov.hk/psi/dd/hk_aqhitc_en.pdf","sourceField":"data_dictionary"}]}
