“…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]. In addition, fine particle sediment may denote slow hydrodynamic energy and particulate OC in water column have enough time to be absorbed on surficial sediment [20,30].…”

“…Downstream tend to have high proportion of slit and clay grain size sediments. It indicates that it might have a low hydrodynamic condition at the estuary [20,30]. The low water flow condition leads to sediments being suspended in water column to have more time to sink and redeposited at the bottom [20].…”

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 sources of metal input are industrial effluents and wastes, urban runoff, sewage treatment plants, boating activities, agricultural fungicide runoff, domestic garbage dumps and mining operations (Tam and Wong, 2000;MacFarlane, 2002;Cox and Preda, 2005;Gonzalez-Mendoza et al, 2007). The heavy metals AS, Cd, Pb, Zn and Cr are of greatest ecotoxicological concern in Chinese estuaries and are often found in high concentrations in polluted sediments (Zhou and Zhu 2006;Li et al, 2007). Mangrove plants can absorb pollutants from the environment and accumulate them in the bodies.…”

A study was performed for investigating accumulation, distribution and toxicological effects induced by chromium (Cr) on the development of the mangrove seedling Kandelia candel (L.) Druce. Seedlings treated with increasing concentrations of CrCl 3 solution (0, 0.5, 1, 1.5, 2, 2.5, 3 mg L -1 , respectively) were grown in a basic nutrient solution for three months. The five month old seedlings were harvested for the experiment. This study showed that Cr treatment significantly decreased growth of K. candel in terms of seedling height, leaf number and total biomass. At the highest 3 mg L -1 Cr exposure, there was a 34.47% decrease in final seedling height, 68.95% decrease in leaf number and a 60.65% decrease in total biomass. The present study demonstrates that Cr accumulation ability of K. candel seedlings increased with the increase of treatment strength up to certain level. The concentrations of Cr in root, hypocotyl, stem and leaf ranged from 22.87 to 1.43 mg kg -1 , 1.30 to 0.68 mg kg -1 , 2.42 to 0.91 mg kg -1 , and 1.74 to 0.74 mg kg -1 , respectively. When comparing Cr concentration in different plant parts with respect to their controls, the results showed that treated plant root bioaccumulated high amounts of Cr. Almost 80% of Cr was accumulated mainly in roots. The distribution pattern of Cr in K. candel was Root > Stem > Leaf > Hypocotyl. Our findings indicated that the high concentration of Cr supply may interfere with several metabolic processes of seedlings, causing toxicity to plants as exhibited by chlorosis, necrosis, and finally, plant death.Keywords: Chromium; plant growth; metal accumulation; metal distribution pattern; toxic effect; mangrove.Acumulação, distribuição e efeitos toxicológicos induzidos por cromo no desenvolvimento da planta de mangue Kandelia candel (L.)

As mudas foram colhidas com cinco meses de idade. Este estudo mostrou que o tratamento com Cr diminuiu significativamente o crescimento da RAHMAN, M. M.; CHONGLING, Y.; RAHMAN, M. M.; ISLAM, K. S.

We conducted an analysis of heavy metals content, including As, Cd, Cr, Cu, Hg, Pb, and Zn in sediments from aquatic ecosystems in China measured in recent publications. Then, we evaluated the extent of heavy metal pollution in these ecosystems in seven different industrial districts in China (Dongbei, Huabei, Huazhong, Huanan, Huaxik, Xibei, and Huadong) with the potential ecological risk index. We found that Cd was the most concentrated pollutant, followed by Hg and As, while Cr, Cu, Pb, Zn were found in low concentrations in sediments from all types of aquatic ecosystem in China. Sediments collected from all seven industrial districts were heavily polluted, and the sequence, from most to least polluted was Dongbei>Huabei>Huazhong>Huanan>Huaxi>Xibei>Huadong. All four types of aquatic ecosystem were found to be seriously polluted and the sequence, from most to least polluted was: river>sea>lake>wetland. Specifically, Cd and Hg were the most serious pollutants in all four aquatic ecosystems, and As was also a serious pollutant in rivers. For the seven industrial districts studied the sea was the most polluted ecosystem in Dongbei, the river was the most polluted ecosystem in Huabei, Huanan, Huazhong, and the lake was the most polluted in Huadong, Huaxi, and Xibei.
