    Cameron Highlands is experiencing rapid development as a popular tourist destination in Malaysia. This causes a rapid boost in construction and other tourism-related activities, such as the growth of vegetables, fruits and flowers. Due to that, the water quality of rivers in the highlands has been adversely affected. In this study, Bertam River, as one of the main streams in Cameron Highlands, was monitored to assess its suitability for recreational activities and conservation. Seven sampling points were selected in the river and tributaries: dissolved oxygen, biochemical and chemical oxygen demands (BOD and COD), total suspended solids (TSS), ammonia nitrate (NH3-N) and pH were measured and the water quality index (WQI) was computed during high and average water flow.

    Investigating indoor concentrations of PM10 in an underground loading dock in Malaysia
    (Springer, 2017) Motasem S. Abualqumboz; Nurul Izma Mohammed; Amirhossein Malakahmad; Amina N. Nazif
    Risky air contaminants including PM10 can accumulate inside underground confined loading docks because of the enclosed nature and limited contacts of loading docks with ambient air. Exposure to PM10 can increase morbidity and mortality rates. Hence, this study aimed to investigate and model PM10 concentrations in an underground loading dock located at Kuala Lumpur city center, Malaysia.
