“…The Kelantan and Pahang Deltas were found to be the main anthropogenic sources of 210 Pb input in the surface sediments of the sSCS, with the Kelantan Delta having a higher average 210 Pb level than the Pahang Delta. According to [12,13], the high level of contaminant present in the both rivers was due to the continuous mining and land clearing which in turn elevating the level of contaminant present in the both riverine. The data showed that stations closest to the river mouth in the deltas had higher 210 Pb concentrations and that this trend decreases with increased distance from the river mouth.…”

Radiochemical separation techniques were applied to measure 210Pb radioactivity in samples to determine spatial distribution of total 210Pb radionuclide in surface sediments and water column for the main waters on the Sunda Shelf. The average 210Pb radioactivity level recorded for the Malacca Strait (MS) is significantly higher than that of the southern South China Sea (sSCS); this is attributed to the supply of input from the Andaman Sea in its northern areas, and massive terrestrial processes from bordering land masses. The results reveal that the decreasing trend of total 210Pb in Peninsular Malaysia’s marine sediment starts with the north maritime zone of Malacca Strait (64.28 ± 5.97 Bq/kg) > south maritime zone of Malacca Strait (50.88 ± 6.15 Bq/kg) > east maritime zone of sSCS (41.01 ± 3.07 Bq/kg) > south maritime zone of sSCS (40.78 ± 3.16 Bq/kg). The Kelantan and Pahang Deltas have been identified as two of the main anthropogenic sources of input for total 210Pb in the sSCS with atmospheric transboundary mobilization affecting total 210Pb in the water column. In the Malacca Strait, however, the distribution of total 210Pb might be influenced mainly by in situ processes of the strait’s seafloor and sources origin of sediment. HIGHLIGHTS The Malacca Strait has a significantly higher level of 210Pb radioactivity compared to the southern South China Sea (sSCS), due to input from the Andaman Sea and terrestrial processes from adjacent land masses The decreasing trend of total 210Pb in Peninsular Malaysia’s marine sediment starts with the north maritime zone of Malacca Strait > south maritime zone of Malacca Strait > east maritime zone of sSCS > south maritime zone of sSCS The Kelantan and Pahang Deltas are identified as two of the main anthropogenic sources of input for total 210Pb in the sSCS, while in the sh Strait, the distribution of total 210Pb may be influenced mainly by in situ processes of the strait’s seafloor and sources origin of sediment GRAPHICAL ABSTRACT

“…Manganese able to accumulate for long period and exist in the water, sediments and living things. It is transferred into sediments by physical, chemical or biological processes that can affect living organisms as the waterbody is exposed to the toxic contaminant [42]. Metals tend to accumulate or reacts with particulates and finally settles in bottom sediments of streams.…”

“…The toxicity from manganese contamination has endangered marine organisms. The contaminant will accumulate in tissues and organs of aquatic organism which then being consumed by humans and eventually caused long-term health risks to humans [42].

Manganese is one of the most abundant heavy metals that has been detected in surface water lately. This has become an environmental concern as manganese pose negative impacts on the ecosystem and water supply. The current water treatment process faces challenges in the efficient treatment of manganese at a low cost. This paper reviews the sources, occurrences and negative impacts of manganese towards living organisms as well as the treatment using the adsorption process. The potential synthesizes of low cost and environmentally friendly agricultural waste adsorbent to remove manganese is elucidate in this paper. The outcomes have the potential to reduce manganese concentration in the surface water and minimize the cost of water treatment.

“…However, there is no data on the concentration of dissolved metals have been reported during their study. Besides, a few studies related to the trace metals distribution in the area were determined in the fresh water and sediment samples [11][12][13][14][15] . Less study was conducted to identify the concentration of dissolved metals in the estuaries water due to the high chloride ion in the water sample.…”

This study determined the distribution of selected trace metals (Cu, Cd, Zn and Pb) in the dissolved (< 0.45 µm) and particulate (> 0.45 µm) samples at Sungai Buloh river, Malaysia. The dissolved Zn, Cd, Cu and Pb concentration along the river was in the safety range. The dissolved and particulate Zn, Pb, Cu and Cd concentration was measured and recorded. We found that most of the metals exist in the particulate form and a consistent distribution coefficient (KD) value indicated a low metals deposition occurred along the river. Therefore, it could suggest that most of the anthropogenic input in the upper stream was transported along the river and it might deposited at the estuarine of the river, which could affect the safety level of these metals at the surface sediment and in the aquatic organisms in the study area.
