“…Although atmospheric deposition contributes to PAH input into Lake Erie, major sources are the out#ow of the Detroit River (Kelly et al, 1991) and other point sources of emission on the lake (Eadie et al, 1982;Metcalfe et al, 1997). Total PAHs in sediment of the Detroit River have been found in high concentrations (Furlong et al, 1988). At less grossly contaminated locations on the lake, total PAHs in sediment were 1}3 g g\, and individual PAHs such as #uoranthene reached concentrations as high as 0.6 g g\ (Eadie et al, 1982).…”

“…In later years, the most important application was in waxes (PCT content up to 50%) for the investment casting industry, which produces high precision metal parts for aircraft, nuclear installations, and jewelry (1 (17), in sediments and aquatic organisms (oysters, crabs, shellfish, mummichogs, eels, and gulls) of the Great Lakes (26), the Chesapeake Bay (27,30,33), the Bay of Fundy-Gulf of Maine (3), the Ebro River Delta (32), and the Bay of Biscay (29); in samples of sludge from the coast off Tokyo Bay (18); in marine sediments of the Languedocian continental shelf (12); in sediments of a lake in Berlin (23); in water samples of the Rhine (5); and even in sediments from remote places, such as Winter Quarters Bay in Antarctica (28). In most cases, PCTs were found along with PCBs, polychlorinated naphthalenes, and other major classes of anthropogenic organic contaminants (polycyclic aromatic hydrocarbons and chlorinated pesticides) (12,25,26,28,25). The concentrations of PCTs in sediments and biota were generally lower than those of PCBs, but usually in the same order of magnitude (5,28).…”

In the course of a routine investigation concerned with polychlorinated biphenyl (PCB) contamination of dust collected in classrooms of a junior high school, a group of electron capture detector (ECD)-sensitive compounds with high boiling points were found in addition to PCBs. Using gas chromatographic-mass spectrometric techniques, these compounds were identified as polychlorinated terphenyls (PCTs). Additional measurements indicated that the PCTs were present only in particulate matter collected from the tops of fluorescent light frames but not in air samples obtained concomitantly in the classrooms. Attempts to identify the PCT emission source were unsuccessful. A survey of the literature revealed that PCTs are ubiquitously distributed environmental contaminants, although no data on their indoor occurrence have been reported to date. In view of the toxic effects of PCTs, which seem to be as important as those of PCBs, further attention should be given to the possible presence of PCTs in indoor environments. Images Figure 1.

“…Moreover, determination of the chemical compounds of the sediment, which stores all of the pollutants in the aquatic environment, and its effects on the aquatic organisms have gained importance in the ecotoxicological studies. It was shown by Furlong et al (1988) that many chemicals discharged were hydrophobic in nature. These chemicals might resist degradation by the bacteria and tended to reach high levels in the sediment or biota (Furlong et al, 1988;Alexander 1981).…”

Gölcük Lake (Bozdağ-İzmir) is polluted by the touristic activities and agricultural and domestic sources. Gölcük Lake also adversely impacts human health as the lake water is used for irrigation in agriculture, and the fish caught from the lake is used for nutrition by the community around it. For this purpose, "OECD 201 Algal Growth Inhibition Test", the standard test protocol was evaluated with cultures of green algae Desmodesmus dimorphus as the representative of the first trophic level. This test was used to assess the toxicity of sediment samples collected from five sampling sites in Gölcük Lake. Extracts of sediment samples were assayed in four different concentrations (20, 40, 100, and 200 mg/ml). The effects on the growth of D. dimorphus were examined by scoring cell numbers under the light microscope with a Neubauer haemocytometer counting chamber. According to the results, all extracts, except those from Station 3, inhibited growth of D. dimorphus in increasing concentrations of sediment samples, and inhibition was observed in the following order of stations: 2>5>4>1. Additionally, an increase in the number of algae (hormesis) was observed in the Station 3, depending on time and concentrations. Keywords: Algal Growth Inhibition Test, Pollution, Freshwater, Gölcük LakeÖz: Gölcük Gölü (Bozdağ-İzmir) turizm aktiviteleri, evsel ve tarımsal kaynaklar nedeniyle kirlenmektedir. Gölcük Gölü'nün suyu tarımda sulama amaçlı kullanılmakta ve gölden beslenme amacıyla balık avlandığı için göl suyu, civarındaki halkın sağlığını da olumsuz yönde etkilemektedir. Bu amaçla, "OECD 201 Algal Büyüme İnhibisyon Testi" kısa zamanlı phytotoxicity test yöntemi için standart bir test protokolüdür ve yeşil alglerden olan Desmodesmus dimorphus kültürü birinci trofik seviye temsilcisi olarak değerlendirilmektedir. Bu test, gölden daha önceden belirlenmiş 5 örnekleme yerinden toplanan sediment örneklerinin toksisitesini değerlendirmek için kullanıldı. Sediment örneklerinin ekstraktları dört farklı konsantrasyonda (20, 40, 100 ve 200 mg/ml) test edildiler. Desmodesmus dimorphus'un büyümesi üzerindeki etkiler, sayma kamarası Neubauer hemositometre ile ışık mikroskopu altında hücre sayımı yapılarak değerlendirilmiştir. Sonuçlara göre, 3 numaralı istasyon dışında tüm sediment ekstraktları artan konsantrasyona bağlı olarak Desmodesmus dimorphus büyümesini engellemiştir ve bu istasyonlar sırasıyla 2>5>4>1 nolu istasyonlardır. Ayrıca 3 nolu istasyonda zamana ve konsantrasyona bağlı olarak alg sayısında artış (hormesis) gözlenmiştir.
