“…The sediment core was dated by measuring 210 Pb and 137 Cs (Sanada et al 1999). Total organic carbon (TOC) was measured by the high-temperature combustion method using Shimadzu TOC-5000 (Shimadzu Co. Ltd., Tokyo, Japan), as described previously (King et al 1998).…”

Abstract. Endocrine-disrupting chemicals with estrogenic activity (e.g., alkylphenols) have been detected in coastal Japan. We aimed to determine estrogenic activity in extracts of river water, seawater, sediments, and sediment cores from Tokyo Bay by in vitro gene expression assay. Fifty-one of 57 extracts had some estrogenic activity. E 2 equivalents (ng E 2 equivalents per gram dry weight or per liter above the limit of detection) in river water samples ranged from 0.70 to 4.01 ng/ L; in seawater samples from 0.34 to 2.52 ng/L; and in surface sediments from 2.07 to 12

“…The drawbacks to using HCl are the production of hygroscopic salts (e.g., CaCl 2 , MgCl 2 ) which increases the sample drying time, and the introduction of chloride into the sample which could cause difficulties with instrumental analyses. Finally, it should be noted that for all acids mentioned above, there are reports of organic matter loss during carbonate removal (Heron et al 1997;King et al 1998;Lohse et al 2000;Bisutti et al 2004). Although the mechanisms for organic matter loss are unclear, they may include loss of acid volatiles, decarboxylation, oxidation, and spills.…”

“…Mucci et al (2000), melaporkan bahwa sedimen laut memiliki kandungan karbon organik sebesar 4,69%. Wefer (1989) dalam King et al (1998), juga melaporkan bahwa total nitrogen dalam sedimen laut berkisar antara 2,4 -10,2%, dengan demikian maka kandungan karbon organik sedimen disetiap perairan tidaklah sama tetapi fluktuasi nilai karbon organik yang diperoleh dalam sedimen di lokasi penelitian telah menunjukkan banyaknya sedimentasi yang berasal dari bahan organik dan konsentrasi tersebut sekaligus menjadi petunjuk bahwa perairan tersebut telah tercemar bahan organik. Ndungu et al (2016), mengatakan bahwa tingginya kandungan karbon organik dalam sedimen dapat menyebabkan kemampuan sedimen untuk mengikat logam berat meningkat seperti Hg yang terikat oleh MeHg.…”

The study was conducted using survey method. The sampling points were based on the distances from pond outlet toward offshore which were 25, 100, 200, 400, 800, 1600 and 3200 m. Sample of sediments were collected using sediment grab then about 1-1.5 kg of samples were stored in plastic bags for analysis of pH, redox potential, carbon organic. The in-situ measurements were conducted for pH and redox potential using a pH mV and pH meter, probe HANNA instruments HI 8424, whereas other sediment quality variables were analysed under laboratory. The results of this study showed that the pH sediments were ranged between 6.38 – 7.80 with average of 7.36. Redox potential of sediments ranged between -186 to 72 mV, average - 88.39 mV. Carbon organic ranged between 0.30 – 9.85%, average 3.09%. Organic matter ranged between 0.30 – 9.85%, average 3.16%. Total nitrogen were ranged between 0.05 – 0.25% with average of 0.17%, phosphate were 8.62 – 187.71 mg/L with average of 88.43 mg/L. Based on the sediment characteristics, the sediments of Punduh Bay had been polluted by organic matters.
