“…Based on the literature, accumulation of PCDD/Fs in aquatic invertebrates is nonselective (i.e., it follows the congener patterns of their environment) [8,12,32]. The data on PCDEs in invertebrates is scarce, but similarities in congener patterns of fish, mussels, and sediments have been detected, indicating general nonselectivity in accumulation [16,32].…”

Sediment and chironomid samples were collected from a river in the vicinity of and downstream from a closed chlorophenol production plant, and they were analyzed for polychlorinated dibenzo-p-dioxins and furans (PCDD/F) and polychlorinated diphenyl ethers (PCDE). Bioaccumulation of these compounds from the sediments by the oligochaeta, Lumbriculus variegatus, and semipermeable membrane devices (SPMDs) was studied in a 28-d bioaccumulation test. The sum concentrations of PCDD/Fs and PCDEs in sediments varied spatially, peaking at the site below the production plant, but the congener composition remained fairly constant throughout the river. The sum concentrations of chironomids, oligochaetes, and SPMDs all varied independently of sediment concentrations. Both invertebrates accumulated more PCDEs, whereas PCDD/Fs dominated in sediments and SPMDs. Despite the variable sum concentrations, similarities were observed in concentrations and compositions of individual congeners. A significant correlation was found between sediments and oligochaetes, and between oligochaetes and chironomids, for both PCDD/Fs and PCDEs. These results suggest that bioaccumulation of PCDD/Fs and PCDEs in invertebrates is nonselective. Furthermore, the laboratory bioaccumulation tests seem to yield relevant results. The SPMDs were found to give good predictions of the PCDD/F concentrations of sediments and oligochaetes. For PCDEs, the estimates were slightly poorer, but still useful for preliminary concentration assessments.

“…in water is the very low concentrations near or below the detectable analytical limits at which they often occur. In water, concentrations vary widely over time, therefore the number of analyses needed for statistical processing is high (7). Interpreting trace contaminants concentrations in water and sediment and predicting the threat they pose to aquatic life under variable physical-chemical conditions is very difficult.…”

This article examines the presence, distribution, nature and sources of 19 Polycyclic Aromatic Hydrocarbons (PAH), in Patellae (patella vulgate L.) and seaweed (vulva) sampled 10 in different stations of Sicilian coastal environments and analyzed for their polycyclic aromatic hydrocarbon (PAH) content. Analysis was performed by gas chromatography/mass spectrometry (GC/MS) with selected ion monitoring (SIM), 15 after saponification of the sample and clean up of the extract. In the limpets the total concentration of polycyclic aromatic hydrocarbons ranged from 34 to 750 μg/Kg of dry matrix. The relative standard deviation (RSD) of the replicas on the concentrations of individual compounds 20 ranged from 4 to 20%. The accuracy of method was estimated by analyzing "blank" samples spiked with known quantities of analytes and the recover percentage was 82 ± 12%. The detection limit (LOD) of analytical procedure was less than 0.2 μg/Kg d.w. for all analytes. The quantification 25 limit (LOQ) of analytical procedure was less 0.7 μg/Kg d.w. The resulting distributions and weight ratios of specific compounds are discussed in terms of sampling location and origin. The results obtained show that levels of contamination vary from one sampling station to the next, 30

“…1,2 Mercury and aromatic organochlorine compounds, polychlorodibenzofurans (PCDF), polychlorodibenzo-p-dioxins (PCDD), polychlorophenoxyphenols (PCPP) and polychlorodiphenyl ethers (PCDE), polychlorocymenes (PCYMs), free and bound (Fand B-) chlorophenols, chlorocatechols and chloroguaiacols (PCP, PCC and PCG), polychloroanisoles (PCA) and polychloroveratroles (PCV), could be quantitated by comparing with authentic reference compounds both in sediments and in exposed biota. [3][4][5][6][7] The major chloroaromatic contaminants in sediments originate from two industrial sources in the City of Kuusankoski, located 50 km upstream of the outflow to the Gulf of Finland. The bleaching of pulp with chlorine chemi-cals since the early 20 th century is the source of chlorocymenes, free and bound chlorophenols, PCAs and PCVs.…”

Analyses of chlorinated aromatic contaminants in industrially polluted sediments of the Kymijoki River, SouthEast Finland, were extended to the search of previously unknown pollutants by gas chromatography/mass spectrometry. In the fraction of persistent organochlorines, a series of substances were identified as octa-to tetra-chlorinated phenyl esters of 2-hydroxybenzoic acids (most probably all polychlorinated phenyl salicylates). All their mass spectra were previously unknown and interpreted by fragmentation rules, appearance energy calculations and simulation.
