Abstract:

This dataset contains the concentrations of polycyclic aromatic hydrocarbons (PAHs) in liver tissue of golden tilefish (Lopholatilus chamaeleonticeps) collected aboard multiple R/V Weatherbird II cruises WB1304 (2012-08-13 to 2012-08-25), WB1403 (2013-08-15 to 2013-08-30), WB1502 (2014-08-05 to 2014-08-20), WB1602 (2015-08-15 to 2015-08-30), WB1603 (2015-09-10 to 2015-10-02), WB1701 (2016-08-02 to 2016-09-09), and WB1736 (2017-07-18 to 2017-08-01) in the Gulf of Mexico during the Gulf of Mexico-wide surveys from 2012-2017. PAH was extracted from livers with a modified QuEChERS (Bond Elut, Agilent Technologies, Santa Clara, CA, USA) method optimized specifically for this study species. Extracts were analyzed using Agilent’s 7890B gas chromatograph (GC) coupled to a 7010 tandem mass spectrometer (MS/MS) operating in multiple reactions mode (MRM). The dataset contains the location, date and concentrations of multiple PAHs, as well as the total concentration of all polycyclic aromatic hydrocarbon (PAHs). Dataset also includes associated biometric description of fish such as sex, length, weight, fish weight, fish mass and mass of the liver. The cruise documentation was provided for the R/V Weatherbird II cruises WB 1304, WB1403, WB1502, WB1602, WB1701, and WB1736 led by chief scientists Dr. Steven Murawski and Dr. David Hollander.

Methods:

Liver samples were extracted using a modified QuEChERS (Bond Elut, Agilent Technologies, Santa Clara, CA, USA) method optimized specifically for this study species.

Instruments:

Extracts were analyzed using Agilent’s 7890B gas chromatograph (GC) coupled to a 7010 tandem mass spectrometer (MS/MS) operating in multiple reactions mode (MRM).

Error Analysis:

A performance-based QA/QC program was implemented to ensure acceptable levels of analytical accuracy and precision following the EPA’s Method 8270D and the National Oceanic and Atmospheric Administration’s quality assurance and quality control plan for DWH Natural Resource Damage Assessment. The program included the analysis of solvent blanks, procedural blanks, sample replicates, matrix spikes, blank spikes, and matrix-matched standards.
