Air Quality Alert: Hong Kong's AQHI May Reach 'Serious' Health Risk Today

Health risk category for Air Quality Health Index may reach "Serious" Level

The Environmental Protection Department (EPD) forecasted that the health risk category of the Air Quality Health Index (AQHI) at some air quality monitoring stations may reach the "Serious" level later today (September 30).

The EPD has recorded higher-than-normal air pollution levels in some areas since last Thursday afternoon (September 26). Under the influence of the outer subsiding air of tropical cyclone Krathon, the weather today is fine and very hot with moderate northwesterly winds. Weak winds are unfavourable for pollutant dispersion. The intense sunshine enhances photochemical smog activity, leading to the rapid formation of ozone and fine particulates in the Pearl River Delta region. The high ozone level also promotes the formation of nitrogen dioxide.

According to the Hong Kong Observatory, a fresh to strong northeast monsoon will reach the coast of Guangdong tomorrow (October 1). Under its influence, winds along the coast of Guangdong will strengthen in the middle part of this week. It is expected that air quality will improve by then.

With a health risk category in the "Very High" range or above, children, the elderly and persons with existing heart or respiratory illnesses are advised to reduce physical exertion and outdoor activities to a minimum or avoid such activities. The general public is advised to reduce, or reduce to a minimum, outdoor physical exertion, and to reduce time outdoors, especially in areas with heavy traffic. As health effects of air pollutants may vary for individuals, persons who are in doubt or experience discomfort should seek advice from healthcare professionals. The public may visit the Centre for Health Protection's website (www.chp.gov.hk/en/content/9/460/3557.html) for more information on health effects of air pollution and relevant health advice.

The Education Bureau (EDB) urges all schools to visit the EDB website for appropriate measures to safeguard students' health and take note of changes in the index. The relevant hyperlink is as follows:www.edb.gov.hk/en/sch-admin/admin/about-activities/sch-activities-guidelines/index.html.

When the AQHI is at the "Very High" level, employers of outdoor workers performing heavy manual work are advised to assess the risk of outdoor work and take appropriate preventive measures to protect the health of their employees, such as reducing outdoor physical exertion and the time of their stay outdoors, especially in areas with heavy traffic. At the "Serious" level, employers of all outdoor workers are advised to assess the risk of outdoor work and take appropriate preventive measures to protect the health of their employees.

Members of the public can check the current AQHI readings on the EPD's website (www.aqhi.gov.hk/en.html) or by calling the hotline 2827 8541.

Notice on appointments to advisory and statutory bodies

A Government spokesman said today (January 12) that Mr Chan Kin-por recently sought approval from the Chief Executive to suspend his three public positions as appointed by the Chief Executive, until the completion of the work of the Independent Committee in relation to the fire at Wang Fuk Court in Tai Po (Independent Committee). Mr Chan made this request to allow himself more time to dedicate to the work of the Independent Committee. After due consideration, the Chief Executive has agreed to and approved this request. The three public positions are: (1) Chairman of Independent Commission Against Corruption Advisory Committee on Corruption; (2) Non-executive Director of Urban Renewal Authority Board; and (3) Member of Honours and Non-official Justices of the Peace Selection Committee.

On December 12, 2025, the Government established the Independent Committee to examine the causes of the incident and related issues, ascertain the facts, and make recommendations on preventing similar tragedies and on improvement measures. The Independent Committee is chaired by Mr Justice David Lok, with Mr Chan Kin-por and Dr Rex Auyeung Pak-kuen serving as members. The Independent Committee held its first meeting on December 19 last year and aims to complete its work within nine months of commencing operations.

Mr Chan Kin-por wrote earlier to the Chief Executive, expressing his wish to suspend the aforementioned three public positions until the Independent Committee completes its work, in order to dedicate more time and focus to the Independent Committee's tasks. The Chief Executive has agreed to and approved the request.

A Government spokesperson said that since the fire at Wang Fuk Court in Tai Po, both the Government and the wider community have been highly concerned about the causes of the incident and the follow-up work. The scope of the Independent Committee's work is extensive, particularly concerning systemic issues related to bid-rigging and connected interests. Given the numerous issues involved and their complex nature, the Government will fully co-operate with the Independent Committee to ensure that it can complete its work and compile its report within nine months. The Government extends its gratitude to Mr Chan for accepting the appointment as a member of the Independent Committee and for his professional and conscientious approach to the Committee's work. When the Independent Committee's work is completed, the Government looks forward to Mr Chan's continuous contribution through his aforementioned public positions.
