    Assessment of multiresidue pesticides in agricultural soils from Ledang, Malaysia and related potential health risks
    (Technoscience Publications, 2018) Khitam Jaber Nabhan; Wan Mohd Afiq Wan Mohd Khalik; Md Pauzi Abdullah; Mohamed Rozali Othman; Anizan Isahak; Siti Aminah Zulkepli
    The concentration levels of organochlorine and organophosphorus pesticide residues in agriculture soils from paddy field were successfully investigated. Residues were isolated using the Soxhlet extraction method, following a clean-up process (SPE Florosil) and a final determination of targeted compounds performed by using a gas chromatography electron capture detector.

    Chemometric application in identifying sources of organic contaminants in Langat river basin
    (Springer, 2012) Rozita Osman; Norashikin Saim; Hafizan Juahir; Md Pauzi Abdullah
    Increasing urbanization and changes in land use in Langat river basin lead to adverse impacts on the environment compartment. One of the major challenges is in identifying sources of organic contaminants. This study presented the application of selected chemometric techniques: cluster analysis (CA), discriminant analysis (DA), and principal component analysis (PCA) to classify the pollution sources in Langat river basin based on the analysis of water and sediment samples collected from 24 stations, monitored for 14 organic contaminants from polycyclic aromatic hydrocarbons (PAHs), sterols, and pesticides groups.

    Development of A Comprehensive Model for Erosion and Sediment Control towards Good Water Governance: UKM Campus as A Watershed Model
    (The Journal of Institution of Engineers, Malaysia (IEM Journal), 2021) Rahmah Elfithri; Md Pauzi Abdullah; Ahmad Fuad Embi; Mazlin bin Mokhtar; Mohd Ekhwan Toriman; Muhammad Barzani Gasim; Sahibin Abd Rahim; Maimon Abdullah; Anizan Isahak; Noor Ezlin Ahmad Basri; Normaizura Maizan
    This study was carried out to develop a whole ecosystem-based erosion and sediment transport control management system of UKM Campus Watershed which is a sub-basin of Langat River Basin catchment. This is done through the development of an Erosion and Sediment Control (ESC) model for the UKM campus watershed that includes localised technology, information and communication system, as well as awareness and community participation for the greening and rehabilitation of UKM Campus.

    Environmental hazard assessment of metals in marine sediments of Sabah and Sarawak, Malaysia
    (Springer, 2023) Amel. Y. Ahmed; Md Pauzi Abdullah; Saifeldin M. Siddeeg
    The fractionation of 10 metals (As, Co, Cr, Cu, Mn, Ni, Pb, Se, V, and Zn) within labile fractions in shallow marine sediments collected from the coasts of Sabah and Sarawak, Malaysia, was evaluated.

    Fate, distribution, and bioconcentration of pesticides impact on the organic farms of Cameron Highlands, Malaysia
    (Springer, 2018) Yang Farina; Nusrat Munawar; Md Pauzi Abdullah; Mohammad Yaqoob; Abdul Nabi
    Occurrence and distribution of organochlorine pesticides (OCPs), organophosphate pesticides (OPPs), and pyrethroid pesticides (PYRs) residues in the leafy vegetables were analyzed together with the soil samples using gas chromatography-electron capture detector. Edible tissues of vegetables showed detectable residues of these compounds indicating the influence of the conventional farms and nearby organic farms.
