Disinfection By-products in Natural Aquatic Environment and Drinking Water
With the aggravation of environmental pollution, many pollutants detected in large quantities in source waters have been confirmed to be precursors of DBPs, e.g. medicines and personal care products (PPCPs), pesticides and plasticizers, leading to the widely distribution of DBPs (more than 800) in tap water and human matrix. Epidemiological studies have consistently associated the consumption of chlorinated drinking water with an enhanced risk of bladder cancer, endocrine disrupting effects or other adverse health effects. Latest epidemiological studies revealed that known DBPs cannot fully account for the reported adverse health effects induced by consumption of DBPs in the drinking water, suggesting that many DBPs need to be identified and regulated. Of the emerging DBPs, the aromatic DBPs, especially phenolic halogenated DBPs, have been attracting a growing concern due to their low-level effect, higher endocrine disrupting and developmental toxicity compared with commonly known aliphatic DBPs. The concern is that many precursors of halogenated phenol DBPs have been widely found in the source water of Hong Kong (mainly from the Dong River in Guangdong province China). Knowing the occurrence of individual phenolic halogenated DBPs could help to make the guidelines. Therefore, we will sample source waters in Dong River, Llobregat River, different treatment processes of tap water and sewage treatment plants (STPs), and downstream of STPs in Hong Kong. Considering there are limited studies about occurrence of phenolic halogenated DBPs, the massive information obtained in this research will be compared together, which can reflex the contaminated level of these new emerging DBPs in Hong Kong and be facilitate to find the precursors and improve the treatment processes by comparing the differentiation of inlet water and different efficiencies of STPs in Hong Kong.After that, on the bases of massive information of DBPs analyzed in this research and the identification of key phenolic halogenated DBPs, we will develop models to estimate the levels of key DBPs using machine learning method on account of controlling DBPs requires pre-knowledge of their levels in water, which is expensive and time-consuming. The prediction model will facilitate the formulation and implementation of regulations of DBPs and may be a good alternative for monitoring of DBPs in the field.

Children's Non-dietary Exposure to Emerging Flame Retardants Via School and Household Indoor Dust Intake
Risks to human health by emerging flame retardants (FRs), which are incorporated in about 1-30% of the weight of plastic or foam found in products such as furniture, electronics, baby products, textiles and building wire and cable, have become a global environmental health issue for years. Recently, the environmental and human health effect by increasing volume use of other halogenated flame retardants (FRs) such as organophosphate FRs (OPFRs), as a replacement for PBDEs is of concern. More research on sources and levels of human exposure to these two emerging FRs is needed. To evaluate the levels of OPFRs in kindergarten schools and household indoor environment, and predict children’s health risk due to non-dietary exposure (inhalation, non-dietary ingestion and dermal contact), dust will be collected from 18 kindergarten schools and 108 students’ households. Exposure dosage will be conducted based on FRs levels in indoor dust in Hong Kong. Emerging FRs (OPFRs) bound in dust samples will be analyzed. This proposed study will investigate emerging FRs in the indoor environment in Hong Kong and assess the kindergarten children’s non-dietary exposure to levels of FRs. The data will be helpful to develop feasible regulations on FRs and their management in an indoor environment.

Promoting STEM Education: Inquiry-based Learning in Environmental Conservation Based on the Internet of Things (IOT) System
This project aimed at enhancing teaching and learning process about IAQ in primary and secondary school. To achieve this goal, a learning package as well as a set of trials were made. The learning package, which was developed by our research group, included a monitoring instrument, a website and a set of teaching and learning materials. (1) The monitoring instrument was designed and assembled independently in our project. The monitoring instrument was portable and easy to operate to students. (2) The website was designed to visualize the monitoring instrument, provide teaching materials as well as integrate different components of our project. It provided an online platform for students to conduct self-study by following the learning procedures on website. (3) To actually test the effect of our product and designed materials, sharing sessions and relevant workshops were carried out in the project. During the activities, students could try to use our products and monitor the concentrations of several contaminants. From several students’ trails, we further promoted our instrument (e.g. increasing the strength of the shell) and improving our lesson plan design. This project promoted the develop of STEM education and delivering IAQ knowledge in school. For instance, our sharing session in in Lok Sin Tong Wong Chung Ming Secondary School achieved huge success. Many science teachers and students were attracted by the monitoring product and IAQ knowledge. The result comparison of pre-test and post-test also revealed that our design could enhance teaching and learning process in STEM education.

Developing a Science Education on Indoor Air Quality (IAQ) for Primary and Secondary Schools Based on a Pilot Case Study in EdUHK
Microorganisms are ubiquitous in the environment, not only do they cover virtually all surfaces we contact, they also cover our skin and are abundant in the air we breathe. Hong Kong’s worsening indoor air quality (IAQ) has attracted increased attention in the global press. Various studies have been conducted to assess the impacts on human health due to excessive exposure to bacteria polluted indoor air and these data provided evidence that rates of respiratory illnesses and symptoms could be elevated with high bacteria pollution. Most people in Hong Kong spend 80% of time in indoor environment, which presents a major health risk to city residents. The main aim of this proposal is to analyze the IAQ including airborne bacteria at the Education University of Hong Kong (EdUHK). A seminar will be organized to introduce our findings and knowledge of IAQ. After that, we will convert our professional data to an educational kit which is easy to be used for general studies or science teachers to use in the primary and secondary schools. The teaching kit includes (1) one cartoon video introducing IAQ and bacteria; (2) some brochure about IAQ and the bacteria in the air we lived; (3) some compare experiments designed under the different condition (temperature, humidity, air flow, and so on) for science student teachers to cultivate the bacteria aimed to teach them what kind of environment is conductive to bacterial growth; (4) how to improve the air quality in where we lived; (5) related STEM and environmental education, such as the air flow calculation, design of an experiment to count the airborne bacterial, etc. The proposed initiative can support the strategic development of EdUHK. Our vision is to build our core capability in this important strategic research area through incorporating our existing strength expertise in analytical chemistry, toxicology, molecular biology, environmental engineering, and education,, with a view to establish EdUHK as the opinion leaders in environmental issues and education in the local community.

Cultivating Students’ Critical Thinking and Creativity through Web-based and Classroom-based Inquiry
Critical thinking and creativity are long-standing objectives in EdUHK strategic plans and within her generic intended learning outcomes (GILOs). Given considerable uncertainty existing in the process of conducting inquiry, students are required to make their own decisions in every stage of doing it, which intrinsically involves the application and development of both creative and critical thinking that are described as the “heartbeat” of inquiry. Inquiry learning was originally adopted in the school classrooms, and recent years witness increasing advocation of it at the university level. This project intends to make use of both Web-based and classroom-based inquiry to facilitate EdUHK students’ development in high-order thinking. 9 sets of Web-based or classroom-based inquiry activities will be developed, with each for an experimental course. The project will follow the paradigm of practitioner research, including two cycles of implementation. The development of students’ critical thinking and creativity will be assessed through matured instruments in the pre and post-tests, interviews with students, and process data generated in the learning process. This project will be a pioneering effort to systematically implement inquiry learning at the university level in the Eastern world. Its innovation is also reflected in the inclusion of both Web-based and classroom-based inquiry.

School Children's Exposure to Veterinary Antibiotics from Food and Drinking Water and Risk of Obesity in Hong Kong
As one group of pharmaceuticals and personal care products (PPCPs), there’s growing evidence of the long-term health problems linked to too much exposure to antibiotics. Not only does the development and spread of ARGs (antibiotic resistant genes) make the drugs becoming less effective as bacteria becoming resistant to existing medicines, but also antibiotics are changing our bodies, particular those of young children, linking to Type-2 Diabetes and obesity. Driven by increasing use in animal industry, the production and usage of antibiotics has grown up rapidly. A part of antibiotics are left in meat, especially in chicken, pork, cultured fish and milk, which heavily consumed by Hong Kong population, even in drinking water. Results of our previous work and recent monitoring studies suggested widespread occurrence of antibiotics in river water of Hong Kong. Although antibiotics can pose potential threats to human health, most work has been focused on investigating the occurrence and fate of antibiotics in sewage and aquatic environment. The current human health associated with antibiotics may be substantially underestimated. Very limited researches were on the antibiotic residues in food and drinking water, as well as the long-term low-dose exposure to antibiotics with human health, especially with children who are more sensitive to antibiotics. In view of that human exposed to antibiotics mainly from food an drinking water besides medicine therapy, the present study is therefore proposed to develop methods for identifying and quantifying of veterinary antibiotics residues in food (chicken, pork, cultured fish and milk) and drinking water in Hong Kong, and to explore the association between the contaminants with children’s risk of obesity.

Joint University Collaboration to Develop Students’ Competence and Leadership in Promoting Integrated STEM Education
This project facilitates STEM undergraduates and pre-service teachers to cross programme and subject boundaries between different majors of the university partners so that students in different universities could collaborate with each other in undertaking problem solving projects characteristic of STEM. The project involves two stages. The first stage is to provide the necessary inputs of a wide range of content knowledge from different STEM disciplines to further the students’ understanding of STEM. This is achieved by requiring students to attend joint-university lectures/workshops outside their majors. The second stage involves the formation of joint-university multi-disciplinary U-STEMist groups by different STEM majors from different universities. These groups will undertake experiential learning projects to solve problems through engineering designs. Each group will either partner with a social service providers to provide service to the needy or with a school to design STEM activities for school students.

Material Flow Analysis of End-of-Use Cell Phones Generated in Households of Hong Kong
Material flow analysis (MFA) recognizes whether the flow of materials is sustainable in terms of the environmental burden it creates. Numerous pollutants, including persistent organic pollutants (POPs) and heavy metals, are released into the environment (air, water, and soil) during the crude recycling of end-of-life (EOL) cell phones, which cause serious human health risks to local workers and surrounding residents. The current research analyzes the flow of cell phones after the end of their useful phase in households Hong Kong.

Provision of Services for Developing Teaching Resources on Indoor Air Quality for Primary and Secondary Schools
We spend over 70% of our time indoors and the quality of air in the indoor environment has a significant impact on our health and performance. Poor indoor air quality (IAQ) can lead to discomfort and ill health; and absenteeism and lower productivity in the workplace, especially for youngsters. Good IAQ, on the other hand, safeguards the health of the building occupants and contributes to their comfort and well-being. The Government is dedicated to promote good IAQ and public understanding of its importance.Aimed at further enhancement of promotion of IAQ awareness in schools, this project develops a total of three sets of teaching resources, which are for the “General Studies” subject of Primary 4 - 6, the “Science Education” subject of Secondary 1 - 3, and the “Liberal Studies” subject of Secondary 4 – 6, respectively. School teachers can use this teaching resource to enrich their class contents and students can get better understanding of IAQ. Most importantly, students are able to learn some simple but handy practices from this teaching resource and apply them to daily life to improve the IAQ of their surroundings.This is the first teaching resources on indoor air quality for Primary and Secondary Schools in Hong Kong.

Theoretical Implication from a Survey of Food Waste Treatment
Life cycle assessment (LCA) is a tool for evaluating environmental effects of a product, process, or activity throughout its life cycle or lifetime. The methodology of LCA has recently been investigated and proven to be suited for the environmental impact assessment of municipal solid waste (MSW) system. However, seldom LCA studies have been focused on food waste management system. The Hong Kong government will need to adopt a life cycle perspective into the decision-making framework regarding the recent encouraging institutes or housing estates to set up mechanical composters, instead of landfilling. In this pilot study, two management options for food waste generated at HKIEd will be evaluated by LCA method, which is the first attempt in Hong Kong.
