Polychlorinated Biphenyls (PCBs) are persistent organic pollutants with significant bioaccumulation in the global environment. Owing to their high toxicity and lipophilic property, PCBs are potential threat to the human and ecological system.The objective of this work was to investigate the polychlorinated biphenyls in seawater and blue mussels Mytilus galloprovincialis collected in the eastern coastal side of the Algiers bay. Surface and bottom water samples were collected at six different periods from July to October 2002 in the port of Tamentfoust and four locations around the port. Mussel samples were collected from Tamentfoust port and Surcouf beach. After extraction, the PCBs levels were determined in marine water and biological samples by gas chromatography with electron capture detector. Total polychlorinated biphenyls concentrations varied from 4.0 to 18.8 ng Á L À1 in surface and from 4.4 to 16.6 ng Á L À1 in bottom seawater and were relatively high in August (30th and 45th days).In mussels that concentrate the organochlorinated compounds in their tissues, the sum of ICES 7 PCBs concentrations was relatively high. It ranged from 64.2 to 185.8 ng Á g À1 dw (average 125.8 ng Á g À1 dw) in samples collected from Surcouf. The level of contamination in Tamentfoust port mussels was about twice higher (225.2 ng Á g À1 dw).The observed PCBs distribution was close to that of common commercial mixture and suggests an industrial origin of this pollution emitted from a continental source in addition to the port activities. Although the use of target compounds has been banned for more than three decades, they are still persistent in Algiers Bay.

“…The extraction techniques typically used for this purpose provide acceptable results, but are labour-intensive. These shortcomings have been circumvented by using alternative procedures such as those based on microwave-assisted extraction (MAE), which have enabled the successful extraction of various types of compounds from matrices including sediments, soil, plants and water (Ganzler et al, 1990;Paré and Belanger, 1994;López-Avila et al, 1995;Eskilsson et al, 1999;Carro et al, 2000;Christen and Veuthey, 2001;Barriada-Pereira et al, 2004).…”

High performance liquid chromatography in combination with diode array detection (HPLC-DAD) was used to determine morphine, 6-acetylmorphine, cocaine, benzoylecgonine, cocaethylene, methadone and 2-ethylene-1,5-dimethyl-3,3,-diphenylpyrrolidine in human saliva. For comparison, samples were prepared by either liquid-liquid extraction in Toxitubes A or microwave-assisted extraction (MAE), by mixing 1 ml of saliva with 10 ml of chloroform and operating at 100 degrees C for 10 min. Acetonitrile and 0.02 m phosphate buffer at pH 6.5 were used as mobile phase in HPLC in gradient mode. The detector response was linear over the drug concentration range of 0.05-2.0 microg ml(-1) in human saliva. The analytical method was validated by determining its precision and accuracy (n = 5), which were lower than 5% as relative standard deviation and 6% as relative error. Limits of detection ranged from 10 to 35 ng ml(-1); mean recoveries of drugs were from 53 to 95% with Toxitubes A and from 83 to 100% with MAE at two different concentrations (0.1 and 1.0 microg ml(-1)). The proposed method was applied to 24 saliva samples from individuals poisoned with opiates and/or cocaine.

“…A pressurized liquid extraction technique has also been developed to reduce both time and solvent consumption [7], but at a high capital cost for analytical equipment [8]. Microwave-assisted extraction (MAE) has been successfully applied to the extraction of various persistent organic pollutants (POPs) in marine biological matrices, including polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) [9,10]. Vetter [11] reported the use of MAE to extract brominated compounds, including PBDEs form several types of marine biological tissues, but no performance or validation of the procedure was performed.…”
