EPD Hosts International Conference on Phytoplankton Community Integrity Index at HKUST for Marine Ecological Collaboration

EPD holds International Conference and Workshop on Phytoplankton Community Integrity Index

​The Environmental Protection Department (EPD) is holding the International Conference and Workshop on Phytoplankton Community Integrity Index (PCII) at the Hong Kong University of Science and Technology (HKUST) from today (November 4) to November 6. The event aims to introduce the developments and applications of the PCII, provide training, and strengthen technical exchange and collaboration among professional bodies in this field from Hong Kong, the Chinese Mainland and overseas.

The EPD, drawing on the latest international practices, has successfully developed a biological indicator, the PCII, to address and manage nutrient enrichment in coastal and estuarine waters. The developments and applications of the PCII and the associated study findings were reviewed by academic scholars and published in an international scientific journal in February 2024.

Speaking at the opening ceremony, the Director of Environmental Protection, Dr Samuel Chui, highlighted that the Conference aims to create a platform for sharing and promoting the latest developments and applications of the PCII and other relevant biological indicators, so as to provide useful reference for the future development of ecologically based assessment methods on evaluating eutrophication risks and assessing ecological impacts, and to further enhance co-operation between the Hong Kong Special Administrative Region Government and the Chinese Mainland in marine ecological environment protection, in order to achieve the target of jointly building the Greater Bay Area into a world-class beautiful bay area.

Two phytoplankton experts from the Scottish Association for Marine Science in the United Kingdom were invited to present on the theory and operation mechanism of the PCII, as well as the relevant biological indices and evaluation approaches recently developed and applied internationally (e.g. in the European Union). Chinese Mainland representatives in attendance came from the National Marine Environmental Monitoring Center of the Ministry of Ecology and Environment, the World Sustainable Development Institute, the Department of Ecology and Environment of Guangdong Province, and the Ecology Environment Bureau of Shenzhen Municipality. Participants from Hong Kong included representatives from government officials and academic sectors such as the EPD, the Agricultural Fisheries and Conservation Department, the HKUST, the City University of Hong Kong, and the Hong Kong Metropolitan University.

The PCII provides an objective and scientific assessment on coastal eutrophication as it analyses the impact of nutrient levels on phytoplankton communities in marine ecosystems. The PCII can be used to supplement traditional nutrient water quality standards with key indicators of ecological or biological responses, thus improving the assessment of eutrophication risks in coastal and estuarine waters and better promoting pollution control in a precise and scientific manner. This enhances the cost-effectiveness of managing eutrophication. The EPD has already adopted the PCII to assess the eutrophication status of marine waters. For more information on the PCII and relevant monitoring data, please refer to the EPD's dedicated website (www.epd.gov.hk/epd/english/environmentinhk/water/hkwqrc/waterquality/phy_mon.html) and the annual report on Marine Water Quality Report in Hong Kong in 2024 (www.epd.gov.hk/epd/sites/default/files/epd/english/environmentinhk/water/hkwqrc/files/waterquality/annual-report/marinereport2024.pdf).

ExCo Non-official Members congratulate successful launch of manned Shenzhou-23 spacecraft

The following is issued on behalf of the Executive Council Secretariat:

Non-official Members of the Executive Council (ExCo) today (May 24) warmly congratulate the successful launch of the Shenzhou-23 manned spaceship. They extend their highest respect to all crew members, including Dr Lai Ka-ying, the first payload expert from the Hong Kong Special Administrative Region (HKSAR).

The Convenor of ExCo Non-official Members, Mrs Regina Ip, said, "This year marks the beginning of the National 15th Five-Year Plan. This mission is the first manned spaceflight during the 15th Five-Year Plan period and the first time a Hong Kong expert has participated, which is a truly momentous occasion. I extend my heartfelt gratitude to the country for providing Hong Kong's innovation and technology talent with this invaluable opportunity to take part in the country's aerospace endeavours. Dr Lai has successfully undergone the rigorous selection and training process to become one of the country's fourth batch of astronauts, and China's fourth female astronaut to reach space, contributing Hong Kong's strength to the national aerospace endeavours. She has exemplified the Lion Rock spirit of rising to challenges with resilience and perseverance. Her courage and determination are truly admirable, and all Hong Kong citizens are immensely inspired and proud of her. The understanding and support of her family are also essential for her to participate in this mission with resolution. I am deeply grateful for their support and commitment.

"The HKSAR Government is actively developing Hong Kong into an international innovation and technology centre and supporting promising research projects through various funding schemes. As an example, the Multi-Spectral Imaging Carbon Observatory (MUSICO) camera, developed under a project led by the Hong Kong University of Science and Technology and funded by the Government's Innovation and Technology Support Programme Special Call on Aerospace Technology, has successfully arrived at China's Tiangong Space Station, becoming Hong Kong's first scientific payload aboard the station. This fully demonstrates Hong Kong's innovation and technology edge and talent advantages."

Non-official Members of the Executive Council expressed their heartfelt gratitude to the country for its high recognition of Hong Kong's innovation and technology talent, development and achievements, as well as its profound emphasis, care and support for Hong Kong's scientific and technological development. They firmly believe that the HKSAR Government will seize this historic moment to nurture more outstanding innovation and technology talent for the country and Hong Kong, and better integrate into and serve the country's overall development.
