A total of 120 fish samples were collected from different water sources in El Fayoum Governorate, (Bahr El Banat agricultural drainage, different fish farms and Al Rayaan Lake). and represented by Clarias gariepinus from Bahr El Banat agricultural drainage, different fish farms (15 each), Mugil cephalus from different fish farms and Al Rayaan Lake (15 each), Solea solea (30 samples) and Oreochromis niloticus from Bahr El Banat agricultural drainage, different fish farms and Al Rayaan Lake (10 each). Fourteen organochlorine compounds were analyzed by gas chromatography. Fish samples from Bahr El Banat revealed the highest mean levels of p,p'-DDD, endrin, endosulfan, γ-chlordane, heptachlor and γ-HCH, while fish samples from Al Rayaan Lake have shown the highest mean level of methoxychlor, p,p'-DDT, p,p'-DDE, dieldrin, heptachlor epoxide, δ-HCH and α-HCH. Most of the examined fish samples from different species, are within the maximum residue limits and should not pose a health risk to consumers. The public health hazards were discussed as well as recommendations were done.

“…In other bivalves, PCBs concentration levels were determined. They varied from 29.0 to 37.6 ng Á g À1 ww in Donax sp from Egyptian Mediterranean coast and Nile estuary (Abd-allah et al 1998), from 0.960 to 107 mg Á kg À1 dw in Mactra Coralina, whereas in Tapes decussata concentrations ranged from 0.534 to 10.1 mg Á kg À1 dw (Khairy 2009). In bivalve Brachiodontes sp.…”

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.

“…Toxaphene and dieldrin were detected in significant concentrations in all the samples analysed with a concentration ranges of 10-97 μg/kg and 4-36 μg/kg respectively, while chlordane ranged from 3 to159 μg/kg. Abd-Allah et al (1998) determined pesticide residues in fish and bivalve Donax sp collected from Abu-Quir, Demiatta and Gamasa in Egypt. Results from the samples analysed using capillary GLC showed that p,p'-DDE dominated the DDT profiles in all locations, occurring in a range of 2.0-4.1 μg/kg and 3.3-18.0 μg/kg in fish and bivalve, respectively.…”

The widespread use of organochlorine pesticides (OCPs), essentially for the control of insects and the cultivation of food crops, has led to the pollution of ecosystems. Despite being banned several years ago in the developed world, extensive use remains ongoing on the African continent. This review summarizes the occurrence, distributions, sources, and trends of OCPs in seven environmental matrices (atmosphere, water, sediments, soils, biota, human fluids and food products) in Africa. Findings in this review revealed that α-HCH, β-HCH dichlorodiphenyltrichloroethane (DDTs), and endosulfans were the most persistent OCP residues in the African environment, particularly DDTs in breast milk samples occurring in levels above the WHO stipulated limits, thus indicating a call for concern. Also, there was paucity of data available on OCP concentrations in ambient air. Future research efforts should prioritize testing these pollutants in the atmosphere, especially in countries where they are used more frequently. While most POP analysis studies used gas chromatography coupled to electron capture detector or mass spectrometer, it is recommended that further studies should use more sensitive analytical techniques such as gas chromatography with tandem mass spectrometry (GC-MS/MS), or gas chromatography coupled to high-resolution mass spectrometry (GC-HRMS). These instruments allow for the detection of secondary and tertiary metabolites, especially those found in water, biota and food products, which are critical vectors of OCPs to human and animal bodies. Training of farmers and other domestic users on the handling of pesticides is proposed.
