    Exposure to the haze pollutants may cause a diverse range of health impacts including symptoms that lead to treatment-seeking behavior, outpatient and emergency department visits, and hospitalization for moderate and severe cases and mortality for the worst-case scenarios. This study is carried out as an effort to understand how the haze occurrence that has been plaguing South East Asia affect the health of the citizen in Malaysia, particularly in Johor due to its close proximity to Sumatra which has been identified as one of the hotspots for frequent forest fires. The study is done in Larkin and Pasir Gudang where health cases caused by poor air quality such as conjunctivitis, URTI and asthma have been identified while HYSPLIT model indicates the trajectory of the wind at different heights to help us understand how wind movement during the selected time of the year causes haze formation.

    Decision analysis of multi-pollutant control strategy for coal-fired power plant in Malaysia
    (Springer, 2016) Mutahharah M. Mokhtar; M. Rozainee Taib; Mimi H. Hassim
    The promulgation of Environmental Quality (Clean Air) Regulations 2014 on emissions from coal-fired power plants in Malaysia has prompted power plant operators to adopt emission control strategy that complies with the new emission limits. Currently, various emission control strategies are available to achieve the desired emission level. Each strategy offers unique advantages and disadvantages, depending on the objective of emissions control, process nature, and constraints on the resources incurred. To address this challenge, a proper decision-making analysis needs to be performed. In this paper, a systematicdecision analysis methodology is proposed to select the most effective multipollutant control strategy that is compatible for coal-fired power plants in Malaysia.
