“…Laboratory and field experiments confirmed the capability of tetra-and trialkyllead to accumulate in mussels (Chau et al, 1988), snails (Krisnan et al, 1988), fish (Wong et al, 1989;Forsyth et al, 1990;Neves et al, 1990) and birds (Bull et al, 1983;Forsyth and Marshall, 1986). For aquatic organisms the accumulation of organic lead is most pronounced in fish, due to their high lipid content (Wong et al, 1981).…”

The distribution of inorganic and organic lead species in atmospheric and surface waters from the Sibenik area (central part of the Eastern Adriatic coast) was investigated. The concentration range of lead compounds in rainwater was 12,000 to 57,000 ng Pb L-1 for total lead, and 10 to 96 ng Pb L-1 for ionic alkyllead compounds (mostly in the form of trialkyl derivatives). In seawater, trialkyllead compounds were detected in concentration from <0.5 to 12.5 ng Pb-1 L, which represented 0.5 to 6.8% of the total lead. These results were compared with data obtained elsewhere, and the influence of lead compounds emitted from leaded gasoline (from automobiles and gasoline stations) on the adjacent water body is elucidated.

“…Unfortunately, some metal-processing industries are responsible for various forms of environmental pollution. This results in various impacts on living organisms, including birds, when metal-containing liquid or solid wastes are knowingly or unknowingly discharged into freshwater ecosystems (White and Kaiser, 1976;Kempf and Sittler, 1977;Bull et al, 1983;Ohlendorf et al, 1986). These industrial spillages stimulated the research into the possible use of aquatic organisms to evaluate and monitor the various forms of pollution (e.g.…”

The Red-knobbed Coot Fulica cristata is an abundant aquatic bird in South Africa and was anticipated to have indicator abilities for metal pollution. This hypothesis was tested on 83 coot samples collected from five selected aquatic ecosystem areas supporting substantial coot populations, of which various abiotic and biotic components are known to contain varying levels of a number of metals. The aim of this study was achieved by determining the variations in Cd, Cu, Ni and Pb concentrations in liver, kidney, bone and blood samples, with the use of standard flame atomic absorption spectrophotometry techniques. Coots from the Germiston Lake sampling site showed the highest concentrations of cadmium in liver (2.2 µg/g d.w.) and kidney (5.4 µg/g d.w.). The absence of metalprocessing industries in the catchments of the Florida Lake and the Steynsrus farm dams reflects the low liver and kidney concentrations of Cd, Ni and Cu, respectively. The blood of the Natalspruit wetland coots contained the highest dry weight concentrations of Ni (11.4 µg/g), Cd (1.8 µg/g) and Cu (14.4 µg/g). The statistical evaluation points towards small-scale geographical differences, especially in the concentrations of Cu, Ni and Pb and in the liver, kidney and blood. However, in terms of actual metal concentrations recorded, no significant differences existed between coots of the reference site (Steynsrus farm dams) and those from the other four localities. It is concluded that the impact of metal-containing diets on the tissue concentrations of these metals in birds plays a far more significant role compared to the migratory habits or short-range movements of the coots.

Diğer yandan, gerek sanayi artık ve atıklarıyla, gerekse de beminin yanması neticesi ortaya çıkan kalıntılarıyla önemli bir çevre kirleticisi olan kurşun bir yandan ekolojik dengenin bozulınasına (5,9,13,20), bir yandan da besin zincirine girerek (2, i i, 14,15,16,17,23) insanlar için önemli bir sağlık sakıncası doğurur.…”
