Zusammenfassung
Die Gehalte der Schwermetalle (Kobalt, Nickel, Kupfer, Cadmium, Quecksilber und Blei), die im Fleisch der Miesmuscheln (Mytilus galloprovincialis Lamarck) aus der Zucht des Golfes von Triest gefunden werden, haben eine Normal- oder Log-Normal-Verteilung beim statistischen Test, der für die Asymmetrie der Verteilung empfindlich ist. Eine Log-Normal-Verteilung beschreibt fast alle Spurenmetalle, besonders toxische Schwermetalle, wie Cadmium, Quecksilber und Blei. Die positive Asymmetrie der Verteilung dieser Metalle ist ähnlich, obwohl die Varianzanalyse nach einfacher Klassifikation angibt, daß der Mittelwert der Stichprobenverteilung aus verschiedenen Gesamtheiten kommt, welche die einzelne Zucht kennzeichnen.
Summary
The concentration of heavy metals (cobalt, nickel, copper, cadmium, mercury and lead), which are present at trace levels in the edible part of mussels (Mytilus galloprovincialis Lamarck) from hatcheries in the gulf of Trieste, is normally or log-normally distributed, according to a statistical test sensitive to asymmetry of the distribution. A log-normal distribution appears valid for describing nearly all trace metals, in particular toxic heavy metals like cadmium, mercury and lead. The frequency distribution of these metals has nearly the same asymmetry, although the one-way analysis of the variance shows that sample means come from different population means characterising the particular hatchery.
