    Airborne Particulate Matter and Meteorological Interactions during the Haze Period in Malaysia
    (Springer, 2013) Carolyn Payus; Noraini Abdullah; Norela Sulaiman
    Haze has become a major concern as it has highly significant impacts over Malaysia by several occurrences of haze episodes throughout the country. During the haze periods, airborne particulate matter (PM10) was found as the major pollutant while the other air quality parameters remained within the permissible healthy standards. Haze arise by fires from land clearing in Indonesia that builds up during the dry season affecting tourism, transportation, biodiversity, and contributing to health problems across the region. The variations of the PM10 concentrations are due to various atmospheric processes of emissions, dilutions and accumulations that are affected by meteorological conditions. In this study, an analysis of haze status will be performed using PM10 values from two commercial urban and industrial areas, which involved Kajang and Shah Alam, and one station that was located outside the city, which is in Kota Bahru, Kelantan, that was selected as a rural station for comparison. The aim of this study is to determine the correlation of PM10 concentrations with the meteorological factors (namely on temperature, wind speed and ultraviolet intensity) at different monitoring stations (at different type of land use).

    The presence of total coliform and fecal coliform in the private beach resort of Sabah
    (Universiti Malaysia Sabah, 2014) Carolyn Payus; Usha Nandini
    The research was conducted to determine the hygiene quality of private beach resort seawater in Sabah. Total coliform and fecal coliform were analyzed at five selected sampling locations at the resort located in Kota Kinabalu. Identification was done through the Membrane Filtration Method from APHA standard.
