Transportation of pesticides in estuaries of the Axios, Loudias and Aliakmon rivers (Thermaikos Gulf), Greece

Organochlorine Insecticide Residues in Eggs of the Little Tern ( Sterna albifrons ) in the Axios Delta, Greece

“…E g gS in various stages of incubation were collected in June 1989 from clutches that had been destroyed by flooding due to high tides at a colony on a coastal sand bar in the Axios Delta (40° 30' N, 22° 43' E), a coastal wetland of the Thermaikos Gulf complex, in Macedonia, Greece (see Albanis et al , 1994) for map and more information about the area) and only one egg per clutch was analysed. Soon after collection, the eggs were opened in the laboratory and their contents Correspondence to: T. A. Albanis were placed in chemically cleaned glass tubes that were then preserved deep frozen (-20°C) until analysis.…”

“…In Greece, organochlorine insecticides such as DDT were extensively used before 1972 (Albanis et al 1994). Coastal wetlands, which are widespread in Greece, are areas where pesticides from the agricultural activities of extensive surrounding areas are transported through rivers.…”

“…Coastal wetlands, which are widespread in Greece, are areas where pesticides from the agricultural activities of extensive surrounding areas are transported through rivers. In wetlands of the Thermaikos Gulf wetland complex (north-eastern Greece) among 11 pesticides detected in water and sediments three organochlorines, namely BHC, lindane and 4,4'-DDE (a DDT metabolite) were found (Albanis et al 1994). These and some other organochlorines were found in heron chicks and in their food in the same area (Albanis et al 1996).…”

Cloud Point Extraction of Pesticide Residues

“…Prometryne is a ubiquitous environmental pollutant in water and soil. It is frequently detected in groundwater, surface water, and even breast milk (Albanis et al, 1994;Papadopoulou-Mourkidou et al, 2004). Based on one classification scheme (Swann et al, 1983), the soil organic-carbon adsorption coefficient (K oc ) value is within 311-614, indicating that Prometryne is expected to have moderate to low mobility in soil and may be adsorbed to solids and sediment suspended in water.…”

Distribution Οf Metals & Organic Contaminants Ιn Mussels from Thermaikos Gulf

“…In addition, three rivers, Axios, Loudias and Aliakmon, flow into Thermaikos gulf after the drainage of 93,500 ha of agricultural land. Previous pollution studies in the area have shown elevated values for heavy metals in sediments in the vicinity of the pollution sources, namely the industrial zone, the port of Thessaloniki and the sewage outfall (Voutsinou-Taliadouri et al, 1998) and also the presence of some herbicide traces (Albanis et al, 1994;Hatzianestis et al, 2000). The coasts of Thermaikos gulf and its adjacent area, host the most extended and productive mussel aquacultures of Greece (70% of the whole production).…”
