“…Apart from that, grain size sediment would be playing an important role which affects the organic matter bound to surface sediments [25,29]. The fine sediments have been known to be a preference for sorption of chemical compound [4,25,30]. Hence, it is indicated that sediment at lower catchment might possibly have wider surface area to volume ratio of binding site for organic compounds absorption [20,30].…”

“…It was suggesting that the finer grain size sediments might be a significant factor in controlling the TOC content in surficial sediments at Sungai Pinang [14,20,34]. This is because the fine sediments are providing a larger specific surface area and binding sites for organic carbon absorption [4,33,40]. This phenomenon also can be seen at Port Klang, Malaysia as it is reported that the fine grain size sediment had a significant positive correlation with TOC concentration [20].…”

“…According to [2,20], the environmental changes of river such as transportation and process of sedimentary as well as distribution of material input would affect the grain size of sediments. Additionally, upstream zone tends to have coarser grain size sediments which have a higher possibility of strong hydraulic energy which causes the fine sediment particles to have a shorter residence time which reduces the deposits at the bottom of water column [4,33,39]. Moreover, silt and clay have more loose fabric with higher degree of porosity and permeability, which is easier to be transported to downstream and leave coarser sediments on the river bed [25,40].…”

“…The amount of organic matter that can be stored in river sediment is influenced by several factors, for instances, the types and sources of organic compounds introduced, sediment texture, grain particle size and sedimentation [3,4]. In previous sediment geochemical-related research studies, TOC has been proved to be playing a dominant controlling factor as it manipulates the distribution of other components, including chemical component and biological component in aquatic environment [1,5].…”

The concentration of total organic carbon (TOC) and mean size sediment in a total of 24 samples of surficial sediment were determined. From the results of study, the concentration of TOC (5.33%) was found high nearby the housing area at Sungai Pinang. At the downstream of the river tend to have higher concentration of TOC (1.05% -5.33 %) while at the upstream tend to have low degree of TOC in surficial sediments (0.36% -0.78%). The major contribution in TOC contamination at the bottom part of the river maybe due to anthropogenic activities such as waste effluent from urban runoff, industrial activities and boat activities. Apart from that, the mean grain size was probably an important factor that influences the TOC content in surficial sediment at Sungai Pinang. This is because the distribution of the mean grain size that had similar trend to TOC. In addition, the high correlation relationship between TOC and mean grain size were observed and it had accounted for r = 0.67 owing to fine particles of sediment which had provided a large binding capacity for the sorption of organic carbon. Moreover, fine sediment probably indicates slow hydrodynamic energy at the downstream. It might affect the chemical sorption process and allow the particulate organic carbon to accumulate at the bottom of the water column. Thus, fine sediment maybe playing dominant role in the content of TOC in surficial sediment at Sungai Pinang.Keywords: total organic carbon, mean size sediment, surficial sediments, Sungai Pinang Abstrak Kandungan jumlah karbon organik (TOC) dan purata saiz sedimen di dalam 24 sampel sedimen permukaan telah ditentukan. Dari hasil kajian ini, kepekatan TOC (5.33%) didapati tinggi berhampiran dengan kawasan perumahan di Sungai Pinang. Di kawasan hilir sungai tersebut mempunyai kepekatan TOC yang lebih tinggi (1.05% -5.33%) manakala di kawasan hulu sungai mempunyai kepekatan yang rendah dalam permukaan sedimen (0.36% -0.78%). Kemungkinan punca utama untuk pencemaran TOC di bahagian hilir sungai adalah dari aktiviti antropogenik seperti sisa buangan daripada bandar, aktiviti perindustrian dan aktiviti bot. Selain itu, purata saiz partikel kemungkinan adalah faktor penting menpergaruhi kandungan TOC dalam sedimen permukaan di Sungai Pinang. Ini kerana taburan purata saiz partikel mempunyai corak yang sama dengan TOC. Tambahan pula, hubungan korelasi antara TOC dan purata saiz partikel didapati tinggi dalam sedimen permukaan, iaitu r = 0.67 disebabkan saiz partikel yang halus memperolehi kapasiti pengikatan yang luas untuk penyerapan karbon organik. Selain itu, sedimen yang halus berkemungkinan menunjukkan tenaga hidrodinamik yang perlahan di bahagian hiliran. Hal ini berkemungkinan mempengaruhi proses penyerapan dan pengumpulan zarah karbon organik di bahagian bawah turus air. Oleh itu, sedimen yang halus berkemungkinan besar memainkan peranan yang paling dominan kepada kandungan TOC yang dalam sedimen permukaan di Sungai Pinang.Kata kunci: jumlah karbon organik, purata saiz sedimen, sedimen permukaan, Sungai...

“…The attachment of faecal coliforms to the fine particles increases their viability and transport to the sediment bed 43 . The fine grained sediments with large surface area have more adsorptive capacity for organic matter 44 and influence the accumulation of organic matter and bacteria. TOC/TN ratio indicated input of both autochthonous and terrestrial organic matter at CR which supported high abundance of allochthonous coliforms.…”

Estuaries are hotspots of anthropogenic activities. The deposition of pathogenic bacteria in the sediment and their re-suspension into the water column are influenced by riverine discharge and tides. The abundance of Escherichia coli O157:H7, Shigella spp., Salmonella spp., total coliforms (TC) and Vibrio spp. (Vibrio cholerae (VC), Vibrio parahaemolyticus (VP), Vibrio alginolyticus (VA)) was assessed along with the total bacterial count (TBC) and total viable count (TVC) in surface sediments along the banks of the Zuari estuary, Goa, India. The study was carried out fortnightly for a period of 17 months covering three seasons, i.e. pre-monsoon (PreM), monsoon (MON) and postmonsoon (POM). The spatial and temporal changes in the quality of organic matter were also assessed. The organic matter content was high and rich in carbohydrates and proteins towards upstream sites. The quality of organic matter was influenced by the seasons. E. coli O157:H7 was detected only during MON towards the upstream stations. A negative correlation between TC and TBC with salinity was evident indicating the influence of land run-off. The Shigella spp. and VA were high towards the mouth of the estuary during PreM. However, during POM, the TVC, TC and VP were abundant towards the upstream and VC were abundant at the mouth of the estuary. Among the Vibrios, VP and VA were the most frequently occurring bacteria whereas TC and Shigella spp. were dominant among allochthonous pathogens in the sediments irrespective of space and time. In addition to influence of seasons, the sampling time influenced by tidal condition also played an important role in the population dynamics of pathogenic bacteria in the sediments. Future studies should address the interaction of pathogenic bacteria with suspended particles, their transport and survival in the sediments.
