A person who owns a car or who has a college education may be less vulnerable to COVID-19, according to an analysis of cases in Tehran, Iran, one of the early epicenters of the pandemic. While such variables do not inherently lower a person’s risk, they do indicate an infrastructure of protection that persists despite how densely populated a person’s district might be.

“The earth is suffering from several ‘diseases’: global warming, ocean acidification, habitat loss, etc. If any of these diseases remains uncured, other diseases will accelerate and cause new ones to appear, hence putting humanity’s well-being in danger,” said Associate Professor Masahiko Fujii. For this reason, the research staff of the Faculty of Environmental Earth Science keeps on assessing the current global environmental issues and promoting renewable energy sources as a possible solution.
Figure 1: The drawing shows a clam with its foot extending deep into the sediment to gain access to hydrogen sulfide. The foot and mantle of the clam are red due to the presence of haemoglobin for gas transport in the blood, which is an adaptation to the low-oxygen environment. (Drawn by HKBU student Hu Juntong)

A study led by scientists at Hong Kong Baptist University (HKBU) has decoded the genomes of the deep-sea clam (Archivesica marissinica) and the chemoautotrophic bacteria (Candidatus Vesicomyosocius marissinica) that live in its gill epithelium cells. Through analysis of their genomic structures and profiling of their gene expression patterns, the research team revealed that symbiosis between the two partners enables the clams to thrive in extreme deep-sea environments.

Governments around the world are taking steps to slow the pace of global warming. In the report titled "Hong Kong’s Climate Action Plan 2030+", a 70 per cent reduction in carbon intensity by the year 2030 was set. Achieving this ambitious target will require a major change in behaviour at both the corporate and individual levels.

Nestled at the base of a scenic mountain range in the northeast part of Hong Kong, the campus of The Education University of Hong Kong (EdUHK) is rich in biodiversity. Members of the University community recorded over 1,270 observations of 380 species of trees, plants, insects, birds, fungi and reptiles in the worldwide City Nature Challenge 2019.

Hong Kong has been experiencing hotter summers and more scorcher days in recent years due to climate change and heat island effect. Amid the increasing number of “hot nights”, it is found that consecutive “hot nights” are more detrimental to human health than “very hot days”, although the actual temperature does not reach the level of daytime, according to a collaborative research conducted by the Institute of Future Cities at The Chinese University of Hong Kong (CUHK), as well as researchers from the University of Hong Kong. The research also identified that lack of urban greenery and poor air ventilation in a high-density context are factors that lead to more “hot nights” than “hot days” in some areas. The team suggests that better urban planning and building design are long-term mitigation measures.

Large improvements of air quality in China during the COVID-19 lockdown have been widely reported, but new research reveals that the two pollutants most harmful to human health, fine particulate matter (PM2.5) and ozone, were only slightly reduced.

Low oxygen levels in water (hypoxia) pose a significant threat to marine and freshwater ecosystems worldwide, as highlighted in the latest research findings of The Education University of Hong Kong (EdUHK) in an article titled “Low oxygen levels affect reproductive function in female fish – across multiple generations”, featured in Science for Environment Policy (Issue 536). This novel finding shows that hypoxia not only impairs reproduction in female fish (Oryzias melastigma), but the adverse effects can be passed on to their descendants in subsequent generations, posing a long-term threat to the sustainability of natural fish populations around the world.

The first State Key Laboratory of The Education University of Hong Kong (EdUHK) was opened in June 2018, in alignment with the University’s ongoing efforts to promote environmental studies as a discipline complementary to education. As a consortium member of the State Key Laboratory of Marine Pollution (SKLMP), the University’s role is to conduct pioneering research pertaining to solving imminent marine pollution problems that pose a significant threat to our environment and public health.

The present study screened known and unknown organohalogen compounds present in mussel and sediment samples from Hiroshima Bay. The results provided scientific evidence that unknown mixed halogenated compounds are ubiquitous in the coastal environment and possess bioaccumulative potential as high as persistent organic pollutants.

A study by The Chinese University of Hong Kong (CUHK) found that mangroves and other marine wetlands stored 23% more carbon from the atmosphere than previously estimated, which further established the importance of “Blue Carbon” and its contribution to countering carbon emission. This article has been published in the prestigious scientific journal Nature Communications. (https://www.nature.com/articles/s41467-019-14120-2)

 Formation of brominated, chlorinated and mixed halogenated diphenyl ethers and dibenzofurans during e-waste burning
15 Apr 2019
The composition of mixed brominated/chlorinated dibenzofurans (PXDFs) and diphenyl ethers in soils from an e-waste site in Ghana suggests a formation of PXDFs through condensation of the flame retardant PBDEs and subsequent bromine-to-chlorine exchange. PXDFs were substantial contributors of toxic equivalents among dioxins from e-waste burning.
