Oppositional Dynamics of Organic versus Inorganic Contaminants in Oysters Following an Oil Spill

Oppositional Dynamics of Organic versus Inorganic Contaminants in Oysters Following an Oil Spill

The objective of this work was to study the dynamics of the level of organic versus inorganic contaminants in oysters following a significant spill of 15,000 t of heavy oil in the Eastern Mediterranean. Twenty oysters were harvested from each of six selected sites at 72 and 305 d subsequent to the o...

Description
Summary:The objective of this work was to study the dynamics of the level of organic versus inorganic contaminants in oysters following a significant spill of 15,000 t of heavy oil in the Eastern Mediterranean. Twenty oysters were harvested from each of six selected sites at 72 and 305 d subsequent to the oil spill. Results showed a significant decrease over time in the mean of the means of organic contaminants in oysters (total polycyclic aromatic hydrocarbons [TPAH]: 0.354 vs. 0.177 μg g−1 dry weight, P < 0.05; total polychlorinated biphenyl [TPCB]: 0.031 vs. 0.021 μg g−1 dry weight, P < 0.05). Conversely, the mean of means of each of three heavy metals showed a significant increase over time (P < 0.05) (lead [Pb]: 2.791 vs. 3.543 μg g−1 dry weight, P < 0.05; nickel [Ni]: 6.732 vs. 17.682 μg g−1 dry weight; vanadium [V]: 1.874 vs. 15.833 μg g−1 dry weight). The importance of this pattern in oppositional dynamics of organic versus inorganic contaminants in oysters is discussed.
