    (Springer, 2019) Minhaz Farid Ahmed; Mazlin Bin Mokhtar; Lubna Alam; Che Abd Rahim Mohamed; Goh Choo Ta
    Exposure 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.

    Observations of BTEX in the ambient air of Kuala Lumpur by passive sampling
    (Elsevier, 2020) Haris Hafizal Abd Hamid; Mohd Talib Latif; Royston Uning; Mohd Shahrul Mohd Nadzir; Md Firoz Khan; Goh Choo Ta; Narayanan Kannan
    Benzene, toluene, ethylbenzene and xylenes (BTEX) are well known hazardous volatile organic compounds (VOCs) due to their human health risks and photochemical effects. The main objective of this study was to estimate BTEX levels and evaluate interspecies ratios and ozone formation potentials (OFP) in the ambient air of urban Kuala Lumpur (KL) based on a passive sampling method with a Tenax® GR adsorbent tube. Analysis of BTEX was performed using a thermal desorption (TD)-gas chromatography mass spectrometer (GCMS). OFP was calculated based on the Maximum Incremental Reactivity (MIR).
