| polycyclic aromatic hydrocarbon contamination and lumistox solvent extract toxicity of marine sediments in the north aegean sea, greece. | organic extracts of surface marine sediment collected from six sites within the bay of kavala (north aegean sea, greece) were used for determining priority pollutant polycyclic aromatic hydrocarbons (pahs) and doing toxicity testing. pah analyses and lumistox acute toxicity measurements were conducted in two sediment grain-size fractions: silt/clay (< 63 microm) and sand (63-2000 microm). sixteen pah concentrations were found at low- to moderate levels, ranging from 44 to 166 ng/g dry weight in ... | 2002 | 12448024 |
