Item Embargo Public perception towards sewage treatment plants in selected areas in Selangor and Kuala Lumpur, Malaysia(Springer, 1990) C.P. Tso; K.S. Low; G. BalamuruganA public perception survey on sewage treatment plants carried out in selected areas in Selangor and Kuala Lumpur revealed several interesting and unexpected findings. The general perception patterns regarding odour, noise and visual impact, suggest that the perceived intensity is a function of the time of adaptation. It was also revealed that pests constitute a serious nuisance, to which adaptation was not possible.Item Embargo Hubungan pencemaran partikel terampai (PM10) dengan pesakit asma(Universiti Pertanian Malaysia Press, 1996) Zailina Hashim; Juliana Jalaludin; Azman Zainal Abidin; Azizi Haji OmarSatu kajian terhadap 30 orang pesakit asma yang terdiri dari kanak-kanak telah dilakukan di Kuala Lumpur. Objektif kajian adalah untuk mengenalpasti perkaitan di antara PM10 dan serangan asma yang dialami oleh pesakit. Kajian berbentuk epidemiologi prospektif telah dilakukan dari 1 September 1994 sehinggga 31 Disember 1994.

Collection of recyclable material has long been practised in landfill sites as it provides good additional income. Dealers of scrap and recyclable items who operate at the landfill sites provide a source of supply to manufacturing concerns. Glass recycling industries benefit greatly by using recycled cullet, which improves fuel efficiency. Major economic, technical and other constraints related to recycling are discussed.Item Embargo Monitoring carbon sequestration benefits associated with a reduced-impact logging project in Malaysia(Kluwer Academic Publishers, 1997) Michelle Pinard; Francis PutzThe Reduced-Impact Logging Project, a pilot carbon offset project, was initiated in 1992 when a power company provided funds to a timber concessionaire to implement timber-harvesting guidelines in dipterocarp forest. The rationale for the offset is that when logging damage is reduced, more carbon is retained in living trees, and, because soil damage is minimized, forest productivity remains high. To estimate the carbon benefit associated with implementation of harvesting guidelines, a monitoring program was developed based on 1) field studies for measuring carbon stocks and flows; 2) a computer model of forest carbon dynamics for simulating various combinations of harvesting intensity and damage; and, 3) a projection model for calculating carbon balance over the project lifespan.Item Embargo Kemudahterancaman (Vulnerability) Penduduk Terhadap Perubahan Guna Tanah di Selangor(UKM Journal Article Repository, 2004) Shaharudin Idrus; Lim Choun Sian; Abdul Samad HadiArtikel ini cuba meninjau perubahan guna tanah dan litupan tanah yang berlaku dalam tempoh hampir empat dasawarsa (1966 - 2001) menggunakan analisis Sistem Maklumat Geografi (GIS) dan hubungkaitannya dengan keadaan kemudahterancaman kepada kehidupan sosial di sekitarnya.

Current disposal method of landfilling needs improvements to prolong the landfill life and to minimize the problem of land scarcity. Rapid developments and industrialization in Malaysia necessitate a better and more efficient waste management strategy. The mushrooming of urban areas and rural-urban migration has increased the per capita income due to changes in the consumption patterns that led to increased waste generation. The study involved the compilation of data from relevant municipalities on waste generation in Malaysia. The study also includes waste composition analysis according to income level, to determine the trends of composition produced.Item Embargo Centralized wastewater treatment(Faculty of Science, Universiti Malaya, 2004) Chamala Muthu; Agamuthu P.An assessment was conducted of an integrated wastewater treatment plant (WWTP) in Malaysia. The WWTP has been designed to receive multiple effluents from central utility facilities (CUF) and other neighboring plants with varying wastewater characteristics. Commissioning of the plant was necessary as part of the quality assurance for the plant design specification. Operating units of the WWTP during commissioning are the intake collection, effluent monitoring, primary treatment operation, waste homogenizing and biological unit of processes. The assessment includes the monitoring of average flow rate, total suspended solids (TSS), oil & grease (O&G), pH, temperature, chemical oxygen demand (COD), dissolved oxygen (DO), and mixed liquor suspended solid (MLSS).Item Embargo Physiological and morphological responses of locally grown Malaysian rice cultivars (Oryza Sativa L.) to different ozone concentrations(Kluwer Academic Publishers, 2004) S. Ishii; F. M. Marshall; J. N. B. BellMalaysian rice (Oryza sativa L.) cultivars MR84 and MR185 were grown in greenhouse chambers and exposed to four different levels of ozone from 28th August, 2001 to 22nd January, 2002. Four ozone levels were selected in close relation to the Malaysian peri-urban ambient level (approximately 30 ppb, 8 hr mean), the Malaysian guideline level (approximately 60 ppb) and possible future higher ozone levels (approximately 90 ppb). Both morphological and physiological parameters showed distinctive impacts of ozone treatments.Item Embargo Coastal resource development in Malaysia: Is there a need for sustainable mangrove forest management?(Faculty of Science, Universiti Malaya, 2004) Jahara yahaya; Santha ChenayahIn Malaysia, there are working plans for the conservation and management of mangroves in Matang, Perak. Pioneered by the British Administration, the Matang mangroves exemplify an example of sustainable use for timber production and fishery production without compromising the ecological and environmental values of the ecosystem. Thus, management of mangrove forests inherently involves multiple criteria approach for ranking alternatives for its sustainable use. The purpose of this study is to investigate the need for sustainable mangrove forest management in Malaysia. In this paper, first, we discuss the issues involved in proper management of mangroves in Malaysia. Subsequently, we examine the formulation of a sustainable mangrove management plan. We conclude with some recommendations for further considerations.Item Embargo Impact of ambient air pollution on locally grown rice cultivars (Oryza sativa L.) in Malaysia(Kluwer Academic Publishers, 2004) S. Ishii; F. M. Marshall; J. N. B. Bell; A. M. AbdullahThis study presents the first experimental evidence of the sensitivity of rice plants to ambient air pollution from the Southeast Asian tropical region. Two widely adopted local cultivars of rice (Oryza sativa L.), MR84 and MR185, were grown in open top chambers ventilated with charcoal-filtered air and non filtered air, and in adjacent open plots on the campus of University Putra Malaysia. This is located on the south side of the Klang Valley, a rapidly developing area embracing Kuala Lumpur and other satellite cities, but where agriculture remains important The experimental period was from October 2000 to January 2001, corresponding to the main rice growing season in peninsular Malaysia. Adverse impacts on rice growth and yield were observed and were attributed to phytotoxic levels of ambient ozone.Item Embargo Concentrations of trace elements in marine fish and its risk assessment in Malaysia(Elsevier, 2005) Tetsuro Agusa; Takashi Kunito; Genta Yasunaga; Hisato Iwata Annamalai Subramanian; Ahmad Ismail; Shinsuke TanabeConcentrations of trace elements (V, Cr, Mn, Co, Cu, Zn, Ga, Se, Rb, Sr, Mo, Ag, Cd, Sn, Sb, Cs, Ba, Hg, Tl, Pb and Bi) were determined in muscle and liver of 12 species of marine fish collected from coastal areas in Malaysia. To evaluate the health risk to Malaysian population through consumption of fish, intake rates of trace elements were estimated on the basis of the concentrations of trace elements in muscle of fish and daily fish consumption.Item Embargo Environmental change, development and vectorborne disease: Malaysia’s experience with filariasis, scrub typhus and dengue(Springer, 2006) B. H. KwaDuring Malaysia’s rapid economic development into becoming a middle income country in the past several decades, environmental changes resulted in altered land use patterns because of agricultural practices such as large scale rice, rubber and oil palm cultivation. The impact of environmental changes brought about by rice and rubber cultivation affected the breeding habitats of mosquito vectors which in turn affected the prevalence of two strains of lymphatic filariasis in different ways. This article discusses how ecological factors determine the way lymphatic filariasis, scrub typhus and dengue were spread in Malaysia.Item Embargo Distributions and health risks of polycyclic aromatic hydrocarbons (PAHs) in atmospheric aerosols of Kuala Lumpur, Malaysia(Elsevier, 2006) Nasr Yousef M.J. Omar; Tan Chin Mon; Noorsaadah A. Rahman; M. Radzi Bin AbasThe concentrations and distributions of particle bound polycyclic aromatic hydrocarbons (PAHs) collected over a 10 month period in ambient environment, at street levels as well as during a hazy episode are reported. Ambient and street level distributions of PAHs were similar and their occurrence was attributed to vehicular emissions. However, in haze particles, a different pattern of PAHs was observed, characterized by relatively low levels of benzo[a]pyrene (BaP) and high levels of benzofluoranthenes (BFs).Item Embargo A study on construction waste management of a refurbishment project in Kuala Lumpur(Faculty of Science, Universiti Malaya, 2006) Lee Yee Yie; Noor Zalina MahmoodConstruction waste management is an important environmental issue. The huge volume and various compositions of construction waste have made its disposal a serious problem because it leads to environmental impacts such as landfill space and resource depletion. Greater concerns must be given to construction waste generation and management to reduce its burden to the environment. A refurbishment project site situated in Kuala Lumpur was selected for the study by regular site visits and initial environmental review (IER) was conducted to gather information on site activities and waste management practice. Environmental aspects and impacts caused by construction waste management were identified and their significance was assessed quantitatively and qualitatively. Four on-site sorting schemes were proposed and their practicality was discussed.Item Embargo Waste audit and awareness level on recycling program: A case study in Universiti Malaysia Sabah (UMS), Malaysia(UMS, 2006) Kamsia Budin; Sarva Mangala Praveena; Amran Ahmed; Ahmad Zaharin Aris; Ho Chung MunA waste audit was carried out in Universiti Malaysia Sabah on-campus residential colleges (AB, CD and E) from 8 to 22 March 2006 involving 1323 students.
