Environmental assessment of the compounds from creosote-treated pilings in marine environment
A comprehensive ecological risk assessment was conducted to evaluate the environmental impact of creosote-treated pilings in the marine environment at Moss Landing Harbor, Moss Landing, California. The chemical composition of creosote is critical to its fate and effects in the environment. Therefore, a multiple-stage methodology utilizing column gas chromatography with mass spectrometer detector was used for the identification and quantification of polycyclic aromatic hydrocarbons (PAHs) in neat creosote and environmental samples. The risk assessment of 46 PAHs (water soluble fraction) in the marine environment was based on bioaccumulation studies with caged mussels Mytilus californianus and a testing program with the surface sheen, water column, sediment elutriate, pore waters and bulk sediment. Water samples were evaluated using 7-day chronic exposures with Mysidopsis bahia, while bulk sediments were evaluated with 10-day tests with Ampelisca abdita. Testing program included exposure to normal and UV fluorescent lights. The results of this environmental assessment program allow to characterize the extent and magnitude of toxicity of PAHs released from creosote treated pilings and the risk associated with using creosote in marine environment.
