Abstract:

Controlled oil exposure study to evaluate the effects of south Louisiana crude oil chemically enhanced water accommodated fraction (CEWAF) exposure on Florida pompano and reproduction. Data include total polycyclic aromatic hydrocarbon (tPAH) results for exposure solutions, pompano livers, and pompano whole bodies, as well as volatile organic compound (VOC) results for exposure solutions.

Methods:

Tissue samples were surrogated with naphthalene d8, acenaphthene d10, phenanthrene-d10, chrysene-d12, perylene d12 and extracted via EPA method 3545 using a Dionex ASE300, then concentrated to 10ml in DCM for analysis. Water samples were surrogated with naphthalene d8, acenaphthene d10, phenanthrene-d10, chrysene-d12, perylene d12 and extracted via EPA method 3510, and concentrated to 1mL in DCM for analysis. PAHs were analyzed using gas chromatography/mass spectrometry in selected ion monitoring mode using a 0.25 um film thickness, 0.25 mm I.D., and 30 m length capillary column. One microliter of sample was injected at 60ºC, held for 1.5 minute. Temperature was then increased to 325 ºC at a rate of 8 ºC/ min, and held for 3 min. VOC samples were collected in accordance with Pace Analytical collection protocols, then sent to Pace Analytical for evaluation.

Instruments:

Dionex ASE300 Accelerated Solvent Extractor, Agilent 7890A/5975C, Zebron Capillary column

Error Analysis:

Average surrogate recovery 50-150. CCV run before and after every ten sample. CCV passing recovery must be average less than 20%.
