    The number of Leptospirosis cases and deaths in Kelantan from 2009-2015 showed increasing trends with Jeli District had the highest number of fatalities. This study provides information about the ecological parameters of Leptospira sp. at Lata Janggut, i.e., a natural recreational area. In this research, a total of 18 water samples were collected individually from the upstream part of the waterfall, from the shade and direct sun areas for six consecutive weeks from July 26 until August 28 of 2016. Water samples were taken from for the Leptospira sp. availability testing through the morphological characterisation and staining technique. In-situ and ex-situ data were measured as the physical and chemical parameters of water samples. The 16 elements of heavy metal was determined as well. Water quality index (WQI) of the upstream of Lata Janggut was analysed with 64.50 (Class III) and 77.51 (Class II) in the shade and direct sun areas, respectively, according to the WQI value suggested by the Department of Environment (DOE) of Malaysia. Based on the identification, the study area was free from Leptospirosis during the observation period, which correlated with the ecological parameters of Leptospira sp. at Lata Janggut.   &nbsp

    A Review on Adsorption of Heavy Metals from Wood-Industrial Wastewater by Oil Palm Waste

    The use of heavy metals in the manufacturing industry over the past few decades has eventually contributed to a rise in the flow of metallic compounds into wastewater and has raised significant ecological and health threats to living things. Adsorption is an excellent way to treat solid waste effluent, offering significant benefits such as affordability, profitability, ease of operation and efficiency. However, the price of commercial adsorbent namely activated carbon has soared due to its high demand. There is also a green improvement in this method by turning the commercial adsorbent into agricultural waste. In Malaysia, the oil palm waste is such suitable material that can be utilized for making activated carbon, since they are ample and easy to find. Additionally, part of them is agricultural waste that cannot be consumed (i.e. leaves and fronds). Hence, this study aimed to analyse the potential of activated carbon from agricultural waste, namely oil palm waste, in reducing the levels of heavy metals in industrial wastewater

    The huge quantities of textile industry effluents with high concentrations of heavy metals are associated with the water pollution. Among the conventional technologies currently in use for heavy metals removal, the adsorption offers an economical and eco-friendly approach for textile wastewater treatment. Adsorption efficiency is depending on the chemical structure of the adsorbent such as activated carbon from agricultural waste. Banana peel waste as activated carbon has been reported with high efficiency to remove heavy metals from the textile wastewater. The current review describes the impacts of heavy metals from textile industries on human, plants, and animals and the various methods used for the removal process. The paper looked into the various adsorption methods, and the methods used for generating activated carbon from the lignocellulosic materials. Moreover, the agricultural residues are lignocellulosic substances that encompass hemicelluloses, cellulose, and lignin which is denoted as the most stable in terms of thermal factor. The review works focus on lignocellulosic substances as an efficient adsorbent for heavy metals and colour (dyes) removal. It appeared that the adsorption capacity for different types of the biomass ranged from 153.85 to 7.24 mg g-1 for Cd2+ ions, 1067.8 to 18.9 mg g-1 for Cu2+ ions, 175.6 to 1.7 mg g-1 for Ni2+ ions, 566.4 to 7.23 mg g-1 for Pb2+ ions and from 534.2 to 0.45 mg g-1 for Zn2+ ions. These findings indicated that the heavy metals having different affinity to the adsorbent, among the heavy metals Ni2+ and Cd2+ has less affinity and the adsorbent used for the removal these metals need to be prepared with high porosity and surface area
