    Municipal solid waste (MSW) landfills are one of the major source of hydrogen sulphide (H2S) which is the offensive odours potentially creating annoyance in adjacent communities. This project focuses on H2S emission from landfills in Perlis, Malaysia. Landfill gas (LFG) samples were collected and analyzed accordance with NIOSH method 6013. The mean concentrations of H2S in Kuala Perlis Landfill and Padang Siding Landfill are 210.68 ppm and 242.85 ppm respectively. High concentrations of H2S may be a concern for employees working on the landfill site. These results indicate that workers should use proper personal protection at landfill when involved in excavation, landfill gas collection, and refuse compaction. The formation of H2S most likely to be contributed by the biological conversion of sulfate from gypsum-rich soils and landfill wastewater treatment sludges by sulfate-reducing bacteria (SRB) which can utilize dissolved sulfate as an electron acceptor. H2S is conveniently detected by hand held analyzer, such Jerome meter, landfill gas analyzer. In the organic range, in the ease of detection range in the dispersion rate within the landfill site, the monitored H2S gas form a very noticeable concentration with the travelling wind direction. It proved that the dispersion rate of H2S are suitable as tracer to detect route of travelling in a certain distance.

    Abundance of litter exist in our ocean are listed among the crucial threat to the biodiversity that caused a particular concern due to the abundance, durability and persistence in the coastal environment since the area is highly productive. This research paper is to focus on coastal pollution with the objectives of identifying marine litter to relate with the land use in Kuala Perlis, Malaysia. Marine litter is collected at three points along the shoreline stretching 30 meters in length and 5 meters in width. Collected litter varied between categories and the highest amount was plastic weighing 53.15 kg/m2 followed by fabric, wood, glass, rubber and metal. Generally, there are significant relationship between land use and accumulation of marine debris. As there is a development in the area, the accumulation of marine debris increases, in contrast with the small amount of debris found in undeveloped or nonpopulated areas. The accuracy assessment obtained from Landsat 8 year 2014 and 2018 and Kappa statistics shows value range from 0.7 to 0.9 which indicate good classification performance using ERDAS Imagine 2015. Slight changes in urban development, cultivation area and forest with 1 % while for the water bodies and unclassified or cloud with 9% and 8 %.
