Item Embargo Assessment of health risks and individuals’ willingness to participate in drinking water management at flood-prone Pahang River Basin, Malaysia(Springer, 2021) Lubna Alam; Labonnah Farzana Rahman; Minhaz Farid Ahmed; Md. Azizul Bari; Muhammad Mehedi Masud; Mazlin Bin MokhtarRivers, the main source of the domestic water supply in Malaysia, have been threatened by frequent flooding in recent years. This study aims to assess human health risks associated with exposure to concentrated heavy metals in a flood-prone region of Malaysia and investigate the affected individuals’ willingness to participate in managing water resources.Item Embargo Carcinogenic and non-carcinogenic health risk of arsenic ingestion via drinking water in Langat River Basin, Malaysia(Springer, 2020) Minhaz Farid Ahmed; Mazlin Bin Mokhtar; Lubna AlamThe prolonged persistence of toxic arsenic (As) in environment is due to its non-biodegradable characteristic. Meanwhile, several studies have reported higher concentrations of As in Langat River. However, it is the first study in Langat River Basin, Malaysia, that As concentrations in drinking water supply chain were determined simultaneously to predict the health risks of As ingestion.Item Embargo Composition of heavy metals in indoor dust and their possible exposure: A case study of preschool children in Malaysia(Springer, 2013) Mohd Talib Latif; Saw Mei Yong; Azlina Saad; Noorlin Mohamad; Nor Hafizah Baharudin; Mazlin Bin Mokhtar; Norhayati Mohd TahirThe aim of this study is to determine the levels of selected heavy metals (Pb, Zn, Cd, Fe and Cr) at ten preschools in Selangor, Malaysia. Dust samples from the interior of classrooms and surface soils were collected using soft paint brushes while Kimwipes were used to collect samples of dust from interior walls and children's palms. Heavy metals in the dust samples were determined using inductively coupled plasma mass spectrometry (ICP-MS).Item Embargo Hydrological trend analysis due to land use changes at Langat river basin(Thai Society of Higher Eduation Institutes on Environment, 2010) Hafizan Juahir; Sharifuddin M. Zain; Ahmad Zaharin Aris; Mohd Kamil Yusof; Mohd Armi Abu Samah; Mazlin Bin MokhtarThis present study was carried out to detect the spatial and temporal change (1974-2000) in hydrological trend and its relationship to land use changes in the Langat River Basin. To obtain a clear picture of the hydrological parameters during the study period, rainfall data were analyzed. With the help of GIS and non-parametric Mann-Kendall (MK) statistical test the significance of trend in hydrological and land use time series was measured.Item Embargo Impact assessment of rapid development on land use changes in coastal areas; case of Kuala Langat district, Malaysia(Springer, 2015) Sharareh Pourebrahim; Mehrdad Hadipour; Mazlin Bin MokhtarThe first large urban conurbation in Malaysia stretching from the central mountain spine to the west coast has expanded all rounds to emerge as a potential mega-urban region. It covers the area from the Bernam River basin in south Perak to the Linggi River basin in Negri Sembilan. The analysis of the land use change patterns and the prediction of future changes can highlight the problems of continuing current pattern of growth. Kuala Langat as the case study is located in the strategic area, because this area is identified as a Klang Valley II.Item Embargo Non-carcinogenic health risk assessment of aluminium ingestion via drinking water in Malaysia(Springer, 2019) Minhaz Farid Ahmed; Mazlin Bin Mokhtar; Lubna Alam; Che Abd Rahim Mohamed; Goh Choo TaExposure to aluminium (Al) is inevitable in the daily life because of its abundance in the environmental media through natural processes. Meanwhile, several studies have reported a positive association between Alzheimer’s disease and a higher level of Al ingestion through drinking water. The present study is the first of its kind in Malaysia which predicts the human health risk of Al ingestion via drinking water at the Langat River Basin, Malaysia.Item Embargo The impact of urban growth on regional air quality surrounding the Langat River Basin, Malaysia(Springer, 2011) Mohd Talib Latif; Siti Zawiyah Azmi; Ahmad Daud Mohamed Noor; Aida Shafawati Ismail; Zaharizam Johny; Shaharudin Idrus; Ahmad Fariz Mohamed; Mazlin Bin MokhtarStudies of air quality were carried out in the towns of Kajang, Nilai and Banting in the Langat River Basin, southern region of Kuala Lumpur to determine the status and trend of air quality. The determination of air quality was based on several parameters such as suspended solids with diameters less than 10 μm (PM10) and gaseous pollutants of sulphur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), and carbon monoxide (CO). Primary concentration data of air pollutants were compiled through fieldwork studies and combined with secondary data obtained from the regular monitoring data as collected by Alam Sekitar Malaysia Sdn. Bhd. (ASMA) on behalf of Malaysian Department of Environment (DOE) at their stations in Kajang and Nilai.Item Embargo Treated water quality based on conventional method in Langat River Basin, Malaysia(Springer, 2020) Minhaz Farid Ahmed; Mazlin Bin MokhtarThe water of Langat River is not suitable for drinking without treatment because of chemical pollution from both the point and non-point pollution sources, although it is one of the primary sources of drinking water in Selangor state, Malaysia. There is no significant study in Malaysia that has investigated the efficiency of treatment plants to remove metals from treated water. Therefore, Chelex 100 resin-ion exchanged method was applied to investigate the raw water samples and treated water samples of eight treatment plants.
