“…Peran bahan organik seperti asam humus memiliki kapasitas absorpsi lebih tinggi daripada lempung sendiri. Pentingnya komponen asam humus telah ditunjukkan mampu meningkatkan sampai 60 % adsorpsi DDT dalam kolom air laut (Pierce et al, 1974).…”

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.

“…Finally, the enthalpy change associated with the aqueous-system sorption of nonionic organic compounds is typically lower than the solute's heat of condensation from water and is characteristic of a partition process. Based on sorption isotherms for dichlorodiphenyltrichloroethane (DDT) at different temperatures, Pierce et al (1974) calculated theisosteric heat of sorption for DDT to various types of particulate organic matter. The calculated values ranged from + 2 to -4 kcaljmol, which are significantly lower than DDT's heat of condensation from water [about 9.3 kcaljmol as measured by Kile and Chiou (1987)].…”

“…These colloids which are mostly negatively charged, interact with metals to form metal-organic complexes by ion exchange, protonation, Van der Waals forces, coordination complexation, and hydrophobic bonding (see below). In the latter form they are typical carriers of organic micropollutants (Carlberg & Martinsen, 1982), in freshwater (Carter & Suffet, 1982), estuarine (Poirrier et al, 1972), and sea water (Pierce et al, 1974). Colloids, among other properties, are easily biodegradable by microbial processes and may act in the initial stage of contaminant bioaccumulation (Allan, 1984).…”

The review article covers three major aspects of scientific research on sediment-associated contaminants during the last 20 years: (i) identification and monitoring of sources and distribution (sampling; sample preparation; analyses, mainly of non-residual fractions; estimation of pollution potential); (ii) study of processes and mechanisms of pollutant transfer (interactions between dissolved and particulate element species; particle environments; transport and diagenesis: colloids; surface microlayers; particle related processes; bioturbation; dredging operations; remobilization of toxic elements; bioaccumulation of organic chemicals: solid/dissolved distribution of contaminants); (iii) assessment of the environmental impact of particle-bound pollutations (chemical extraction sequence; sediment bioassay; combined chemical/biological test procedures). Enstead, empirical tests developed from multi-disciplinary research on biological, chemical and physical factors are applied for assessing the reactivity, mobility and bioavailability of sediment-bound pollutations and for estimating the validity of remedial measures.
