“…All are possible sources of PAHs. White et al [23] reported relatively high concentrations of both low‐ and high‐molecular‐weight PAHs in composite (sample depth, 30.5 cm) samples collected from Lauritzen Channel sediments, particularly those collected near station 3 in the present study.…”

Abstract-LauritzenChannel is an industrial waterway adjacent to the former United Heckathorn facility in the inner Richmond Harbor area of San Francisco Bay, California, USA. Marine sediments at this Superfund site were dredged from late 1996 through early 1997 to remove the primary chemicals of concern: DDT, and dieldrin. This study assessed the Lauritzen Channel marine environment immediately before and approximately one year after the dredging of sediments. The study included chemical analysis of sediments, tissue concentrations of transplanted mussels, toxicity testing of sediment samples, and characterization of benthic community structure. Results indicated that sediment toxicity to bivalve larvae (Mytilus galloprovincialis) decreased in postremediation samples, but that toxicity to the amphipod Eohaustorius estuarius increased significantly. Assessment of benthos at this site suggested a transitional benthic community structure. In addition, postremediation sediments remained contaminated by a variety of organic chemical compounds, including DDT, dieldrin, chlordane, polycyclic aromatic hydrocarbons, and polychlorinated biphenyls. Tissue concentrations of DDT and dieldrin in mussels (M. galloprovincialis) were lower than those in preremediation samples, indicating that although sediment concentrations of organochlorine pesticides remained high, concentrations of these chemicals in the water column were reduced after dredging. This study demonstrates that the components of the site assessment were useful in determining effectiveness of the remediation activities.

“…Lingkungan redoks merupakan fungsi dari jumlah banyak bahan organik mudah urai dan oksigen terlarut (Chester, 1990). DDD umumnya terbentuk pada suasana anaerobik, sebaliknya DDE terbentuk pada suasana aerobik (Murty, 1986;White et al, 1994), baik di perairan maupun dalam proses metabolisme dalam organisme (Kate et al, 1999).…”

“…Perubahan DDT di perairan sangat dipengaruhi oleh kondisi perairan dan juga bisa terjadi melalui proses metabolisme. DDT di sedimen sebagian besar dikonversi menjadi DDE dalam kondisi aerobik, dan menjadi DDD pada konsisi anarobik (Murty, 1986;White et al, 1994). Di sedimen, fraksi DDD terbentuk secara dominan dari pada DDE pada kondisi aerobik dalam penelitian laju degradasi 14 C-DDT, tetapi DDD sangat sedikit terbentuk dalam tubuh kimah (Kate et al, 1999).…”

DDT (1,1,ethane) and its two derivatives, DDD (1, and DDE (1, ABSTRAKDDT (1,1,1-Tricholor-2,2-bis(chlorophenil)ethane) dan dua derivativenya, DDD (1,1-Dicholor-2,2-bis(chlorophenil)ethane) dan DDE (1,1-Tricholor-2,2-bis(chlorophenil)-ethylene) telah diidentifikasi di sedimen pesisir muara Citarum, Teluk Jakarta. Delapan titik stasiun pengamatan pengambilan sample sedimen didesain agar diperoleh hasil perubahan nilai konsentrasinya semakin menjauh dari Muara Sungai yang dianggap sebagai sumber masukan. Contoh sedimen diambil pada lapisan permukaan dengan kedalaman < 5 cm. Disamping pestisida, tekstur sedimen dan kandungan organik karbon juga dianalisis. Tekstur sedimen umumnya didominasi oleh fraksi halus (lanau dan lempung) berturut-turut berkisar antara 21 -35,8 % dan 17,6 -65,6 %, sedangkan kandungan karbon organik berkisar antara 0,30 -1,49 %. Konsentrasi p',p'-DDT berkisar antara 0,621 -1,187 ppb, p',p'-DDD berkisar antara 0,176 -2,153 ppb dan p',p'-DDE berkisar antara 0.181 -2,254 ppb. Keberadaan total DDT (Σ DDT+DDD+DDE) cenderung berkorelasi positif dengan fraksi halus sedimen yang mengindikasikan perannya sebagai agen pentransport. DDD dan DDE sebagai senyawa derivative DDT yang terbentuk melalui proses-proses kimiawi dan biologi yang terjadi lingkungan perairan dominan kondisi aerobik.

“…All documents containing RI sampling results are listed in Table 1.1. EPA's human health risk assessment (ICF Technology 1994), ecological assessment (EPA 1994), and marine RI (White et al 1994) summarize current site conditions for all media. The human health and ecological risk assessments indicate that the upland conditions at the site do not pose a threat to surrounding communities and that the upland and embankment soil removal actions have reduced the concentrations of contaminants of concern (COCs) in soils to acceptable levels for current and expected future industrial uses.…”

“…In addition, accidental spills, leaks, and releases also occurred during the processing of liquid and dry pesticide formulations, which were conducted both inside and outside the United Levine-Fricke 1990, 1991bWeston 1993). Extensive marine sediment sampling was conducted by Battelle/Marine Sciences Laboratory' (MSL) for EPA in 1993 (White et. al 1994).…”
