    Characterization of landfill leachates and its impact to groundwater and river water quality: A case study in Beris Lalang waste dumpsite, Kelantan
    (Universiti Pertanian Malaysia Press, 2019) Widad Fadhullah; Mohamad Anuar Kamaruddin; Norli Ismail; Nurulilyana Sansuddin; Hasmah Abdullah
    Solid waste management in developing countries including Malaysia is dominated by waste dumpsites which have a high possibility of transporting organic and inorganic pollutants to the underlying groundwater and surface water within the surrounding area. The objective of this study is to characterise the landfill leachates and its surrounding groundwater and river water quality and metals concentrations, namely arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) from Beris Lalang, Kelantan.

    Level of benzene concentrations emitted from motor vehicles in various sites in Nibong Tebal, Malaysia
    (Springer, 2011) Wesam Ahmed Al Madhoun; Nor Azam Ramli; Ahmad Shukri Yahaya; Noor Faizah Fitri Md Yusuf; Nurul Adyani Ghazali; Nurulilyana Sansuddin
    Benzene is classified as carcinogenic compound which is emitted mainly from cars. In this study, benzene was measured at various sites in Nibong Tebal (urban, suburban, town, and rural) of different traffic volume, and traffic counts were performed simultaneously. Monitoring was carried out during the morning and afternoon traffic peaks. The aim of this study is to monitor benzene concentration at several development sites with different traffic flow. The monitoring was done by using indoor air quality meter.

    Monsoonal differences and probability distribution of PM10 concentration
    (Elsevier, 2010) Noor Faizah Fitri Md Yusof; Nor Azam Ramli; Ahmad Shukri Yahaya; Nurulilyana Sansuddin; Nurul Adyani Ghazali; Wesam al Madhoun
    There are many factors that influence PM10 concentration in the atmosphere. This paper will look at the PM10 concentration in relation with the wet season (north east monsoon) and dry season (south west monsoon) in Seberang Perai,Malaysia from the year 2000 to 2004. It is expected that PM10 will reach the peak during south west monsoon as the weather during this season becomes dry and this study has proved that the highest PM10 concentrations in 2000 to 2004 were recorded in this monsoon.

    Statistical analysis of PM10 concentrations at different locations in Malaysia
    (Elsevier, 2011) Nurulilyana Sansuddin; Nor Azam Ramli; Ahmad Shukri Yahaya; Noor Faizah Fitri MD Yusof; Nurul Adyani Ghazali; Wesam Ahmed Al Madhoun
    Malaysia has experienced several haze events since the 1980s as a consequence of the transboundary movement of air pollutants emitted from forest fires and open burning activities. Hazy episodes can result from local activities and be categorized as "localized haze". General probability distributions (i.e., gamma and log-normal) were chosen to analyze the PM10 concentrations data at two different types of locations in Malaysia: industrial (Johor Bahru and Nilai) and residential (Kota Kinabalu and Kuantan).

    Time effects of high particulate events on the critical conversion point of ground-level ozone
    (Elsevier, 2018) Norrimi Rosaida Awang; Nor Azam Ramli; Syabiha Shith; Noor Faizah Fitri Md Yusof; Nazatul Syadia Zainordin; Nurulilyana Sansuddin; Nurul Adyani Ghazali
    Particulate matter (PM), especially those with an aerodynamic particle size of less than 10 μm (PM10), is typically emitted from transboundary forest fires. A large-scale forest fire may contribute to a haze condition known as a high particulate event (HPE), which has affected Southeast Asia, particularly Peninsular Malaysia, for a long time. Such event can alter the photochemical reactions of secondary pollutants. This work investigates the influence of PM on ground-level ozone (O3) formation during HPE. Five continuous air quality monitoring stations from different site categories (i.e., industrial, urban and background) located across Peninsular Malaysia were selected in this study during the HPEs in 2013 and 2014.
