香港浸会大学化学系

香港浸会大学的前身是香港浸会学院,成立于1956年,化学系始建于1967年.当时,由于经费不足,学术活动只限于本科教学.随着香港经济发展,大学毕业生的需求与日俱增.为了适应香港的高等教育发展要求,经浸会学院各方面的努力,由港府批准,浸会学院由一所重教学的专门学院转型为教研并重的高等教育学府,化学系也由单一教学发展为教研并重.硕士及博士课程相继于1988及1992年开设.

香港特区大学的化学教育

香港特区有香港大学、香港中文大学、香港科技大学、香港理工大学、香港浸会大学和香港城市大学。在 1 997年的亚洲大学综合评比中 ,香港有 3所大学 (香港大学、香港中文大学和香港科技大学 )进入前 1 0名 ,而众多的大陆大学中 ,只有北京大学进入前 1 0名。 1 998年 ,香港大学、香港中文大学继续保持前 1 0名的位置。香港地区大学的学制和管理模式基本上是英式的或者是英美混式的。然而 ,大部分教师和几乎全部学生都是中国人 ,他们有着深厚的中国文化背景 ,在香港的教育中蕴含着中西合璧的特殊的东西。1　香港理工大学 (ＴｈｅＨｏｎｇＫｏ…     

Nitrated PAHs in Ambient Air of Hong Kong

Nitrated Polynuclear Aromatic Hydrocarbons (NPAHs) are widespread environment pollutants. Their presence in urban atmosphere, originated primarily from diesel vehicle emissions, is of particular concern because a number of them have been proven to be mutagenic or carcinogenic. Thus, considerable effort has been devoted in recent years on the development of analytical methods for their quantitative measurement.     

Arsenic in Dried Seafood Consumed in Hong Kong

The arsenic concentrations were determined by neutron activation analysis in some popular dried seafood and dried algae consumed in Hong Kong. It was found that dried scallop was the least contaminated, while most of the samples of dried shrimp, dried oyster and dried mussel contained arsenic less than the maximum permissible concentration (MPC). Dried squid was found to contain the highest arsenic and every sample measured contained arsenic higher than the MPC. Action to be taken was recommended.     

Nondestructive multi-element determination of air particulates in Hong Kong

Nondestructive neutron activation analysis employing reactor neutrons and a Ge(Li) gamma-spectrometer has been used to determine the trace element level of air particulates in various areas of Hong Kong. Comparison of the average concentrations of the trace elements of air particulates was made among industrial, heavy-traffic and residential areas. It was found that industrial areas have higher concentrations of Co, Cr, Hg, Mn and Zn, while heavy-traffic areas have very high concentrations of Br. Comparison of the pollution level of Hong Kong with other cities was also made. The average concentrations of Co, Cr, Hg, Zn and Br of air particulates in Hong Kong were found to have higher values than those of other cities. Finally, daily variation of the trace element level in a special area (Hung Hom) had been studied, but no significant variation was found.     

Development and application of photocatalytic coating for roadside NOx mitigation in Hong Kong

A facile chemical method for the development of photocatalytic coating products was proposed based on practical application perspective for the Hong Kong roadside nitrogen oxides(NO_x) mitigation. TiO₂-based photocatalytic coating PC-C film with crystallized size of around 5–6 nm was synthesized with the peptization of H₂O₂. The PC-C coating possesses a super-hydrophilicity surface and is proven to have a NO_x degradation rate of 46.8% with an...     

Radioactivity contents in building materials used in Hong Kong

The radioactivity contents in building materials used in Hong Kong were measured to determine the sources of the high indoor radon concentrations observed in local buildings. The radium contents and the radon emanation coefficients of different building materials were measured by high resolution γ-ray spectroscopy using germanium detectors. The radon exhalation rates were measured using scintillation cells by circulating the exhaled radon from building materials and obtaining the initial growth rates. The radium content and the radon exhalation rates of concrete and bricks used in Hong Kong were found to be higher than those in some other countries, resulting in high indoor radon concentrations probably due to the high radioactivity contents in the aggregates, granitic in nature, used in building materials.     

Hair as an indicator of environmental exposure in Hong Kong

Eleven human hair samples were taken from the Chinese residents of Hong Kong for the study of hair trace elemental level and environmental exposures. Absolute neutron activation analysis and Ge(Li) gamma-ray spectrometry were applied in the determination of the trace elemental level. All results are reported in parts per million except for sulfur and oxygen which are reported in percent. The trace element content of hair from a drug addict was found to be considerably different from other sampled people. Comparison of the normal concentrations of the trace elements of the Chinese residents of Hong Kong was made with those from people of various other national, socio-cultural and environmental backgrounds. It was found that together with a few other trace elements, Ni, Sr, Zr and Hg content of the Chinese Residents of Hong Kong show a higher level than those of the other sampled people.

The role of metrology in chemistry in the upholding of public health and food safety in Hong Kong

The Government Laboratory has been involved in the provision of analytical and advisory services since its formal establishment in 1913 in support of the needs of the community and the commitments of the Government of Hong Kong Special Administrative Region, China. One of the earliest areas of work involves the testing of food samples for maintenance of public health and food safety. Remarkable advances in technology in recent years coupled with the introduction of new policies and regulations, the launching of new international standards and requirements have all contributed to significant and ever-rising demand of accurate, specific, comparable and traceable measurements using the latest technologies for a wide variety of additives, contaminants, residues and genetically modified ingredients in food.Metrology, the science of measurement, has always played a key role in the development and validation of analytical methodologies in the Government Laboratory for the realization of its measurements to the highest level of accuracies and traceability to internationally recognized standards. Besides the application of the latest analytical technologies such as isotope dilution mass spectrometry, tandem mass spectrometry, real-time polymerase chain reactions, etc., the Analytical and Advisory Services Division of the Laboratory develops a quality assurance system in full compliance with the requirements of ISO/IEC 17025 and endeavours to ensure that every analytical methods are validated with the best applicable means and are fit for the intended purposes. In this presentation, the role and application of metrology in chemistry in the measurements pertaining to public health and food safety work undertaken by the Government Laboratory are discussed.Presented at International Symposium on Metrology in Chemistry, 2004 Beijing, China.
