INTRODUCTION
In 1998, the Patrick Center for Environmental Research (PCER) initiated a study on
concentrations of PCBs, pesticides and mercury in fishes of New Jersey. This study was a
follow-up of earlier studies focusing on mercury in freshwater fishes. In 2000, this project was
amended to include additional samples of fish and shellfish (See Appendix I for detailed
information on samples collected). This document summarizes the results of the QA/QC
protocols of this study. The summary of concentrations from this supplemental study includes
results from polychlorinated biphenyl (PCB), organochlorine pesticide (OCP) and mercury (Hg)
analyses (Appendix II) as well as dioxin analysis for certain samples (Appendix III).
I. Mercury
a) Extractions and Analyses:
Strong acid digestions were performed using 10 ml nitric acid on approximately 1 g homogenized wet fish material in a CEM MDS 2100 microwave digestion system. Mercury analysis was
subsequently accomplished on a Perkin Elmer Fimms 400 Cold Vapor AA. Calibration blanks,
intercalibration verification samples, and instrument duplicates were analyzed to ensure
instrument performance and accuracy.
b) Analytical Quality Assurance:
Sample blanks, duplicates, spikes, and a National Research Counsel of Canada (NRC) Standard
Reference Material (DORM-2, dogfish muscle) were digested with the samples to ensure
adequate recoveries. Recoveries for NRC Dorm-2 were compared to the certified NRC values
and were within 94-100% of the actual concentration for all samples digested. The average
relative percent differences (RPD) for duplicates was 11% (ranging from 2 to 20%). Finally,
sample spikes were analyzed and were typically within 95-109% of added concentrations.
II. Polychlorinated Biphenyls and Organochlorine Pesticides
a) Extractions and Analyses:
Homogenized fish samples were stored frozen until extraction. Samples were thawed and 2 g of
the homogenate was sub-sampled using a stainless steel spatula. An additional 2-5 g sub-sample
was taken for moisture analysis. Approximately 30 g of Na2SO4 (previously extracted with
hexane using a Soxhlet extractor and dried) was added to the sub-sample to eliminate water. The
dried sample was placed in a glass thimble and extracted using a Soxhlet extractor with ca.
200 ml dichloromethane (DCM) for a minimum of 18 h. The extracts were sub-sampled for
gravimetric lipid determination. For this, a known volume of extract was transferred to a preweighed aluminum pan. The solvent was evaporated at 110EC for at least 24 h. The residue
remaining (lipid) was weighed and percent lipid was calculated.

Lipids were removed from sample extracts by gel permeation chromatography (GPC) using
DCM as the mobile phase. The collected fraction containing analytes was concentrated by rotoevaporation and a N2 stream. Solid-liquid chromatography using florisil was done as an
additional clean-up step. Using this technique, PCBs (as well as heptachlor, nonachlors, and
DDEs) were eluted from the chromatographic column containing florisil using petroleum ether
(F1 fraction). The remaining organochlorine pesticides were eluted using 50:50 petroleum ether
and dichloromethane (F2 fraction).
Congener-specific PCBs and organochlorine pesticides (Table 1) were analyzed using a Hewlett
Packard 5890 gas chromatograph equipped with a 63Ni electron capture detector and a 5%
phenylmethyl silicon capillary column. The identification and quantification of PCB congeners
followed the ‘610 Method’ in which the identities and concentrations of each congener in a
mixed Aroclor standard (25:18:18 mixture of Aroclors 1232, 1248 and 1262) were determined
by calibration with individual PCB congener standards. Congener identities in the sample
extracts were based on their chromatographic retention times relative to the internal standards
added. In cases where two or more congeners could not be chromatographically resolved, the
combined concentrations were reported (Table 1). Organochlorine pesticides (OCPs) were
identified and quantified based on comparisons (retention times and peak areas) with a known
calibration standard prepared from individual compounds.
b) Analytical Quality Assurance:
Detection Limits: Matrix blanks were generated to monitor possible laboratory contamination
and to calculate the detection limits for PCBs and OCPs. Each matrix blank, consisting of
approximately 30 g of clean Na2SO4, was analyzed using the same procedures as the samples.
Chromatograms of most blanks were void of significant peaks suggesting that little
contamination through laboratory exposure occurred.
The detection limit was estimated as three times the peak area of the signal produced in the
matrix blank. The method detection may be reported on a mass per sample basis or, if extraction
weights of sub-sampled fish remained relatively invariant as in this study (~2 g), a ‘wet weight
normalized’ concentration may be reported. The matrix blank-based detection limits for PCBs
and OCPs ranged from to 0.01 (several congeners) to 18.82 (congener 1) and 0.10 (p,p DDE) to
324 (beta BHC) ng/g wet weight, respectively (Tables 2 and 3). Based on the matrix blanks, the
detection limit for total PCBs (t-PCBs) was 25 ng/g wet weight (excluding congener 1). Based
on the high detection limits for beta BHC and congener 1, we suggest that using our analytical
techniques and instrumentation, these compounds cannot be accurately determined due to
suspected interference (likely coelution). Both of these compounds are very likely not to be
found in any appreciable concentrations in fish samples from this study area because of their
relatively volatile nature (low Log Kow values).
Surrogate Recoveries: Analyte loss through analytical manipulations was assessed by the
addition of surrogate PCB congeners 14, 65 and 166 prior to extraction by Soxhlet apparatus.
These surrogates were not industrially prepared and therefore are not present in the environment.

PATRICK CENTER FOR ENVIRONMENTAL RESEARCH
Average recoveries of congeners 14, 65 and 166 were 102 ± 32%, 81 ± 22% and 102 ± 25%.
Due to the relatively high surrogate recoveries and the low standard deviations, all reported
values for PCB and OCP concentration in this study were not corrected for analyte loss.
Duplicate Analyses: Table 4 shows the results from duplicate analyses of samples for PCB and
OCPs. With a few exceptions, RPDs were low and within past ranges. The average RPD for all
chlorinated compounds was 56%. Average RPD for PCBs is 29% and is within past ranges. For
OCPs, RPDs ranged from 34% for Aldrin to 90% for chlordanes.
III. Dioxin
a) Background:
The following section of this QA/QC report contains the dioxin/furan results (see Appendix III)
of the analyses of 20 tissue samples performed by the Geochemical and Environmental Research
Group (GERG) within the College of Geosciences at Texas A&M University (Directed by Dr.
Terry Wade). These samples were part of GERG’s sample delivery group SDG B1317. The
samples were analyzed as two QC batches DX0492 and DX0493. DX0492 was extracted on
01/24/01 and analyzed on 02/13/01. DX0493 was extracted on 01/30/01 and analyzed on
02/21/01.
b) Analytical Results/Methodology:
The samples were extracted and analyzed following the procedures contained in EPA Method
1613 Rev. B and GERG SOP 9722. The analyte concentrations were determined using labeled
surrogates added to the sample prior to extraction.
Quality Control:
Calibrations
The analytes are calculated using an average response factor based on the form:
RRF (n) = (Ax * Cqs) / (Aqs * Cx)
RRF (m) = (Aqs * Cis) / (Ais * Cqs)
where
Ax = sum of the integrated ion abundance’s of the quantitation ions for unlabeled PCDDs
and PCDFs,
Aqs = sum of the integrated ion abundance’s of the quantitation ions for the labeled
quantitation standards,
Ais = sum of the integrated ion abundance’s of the quantitation ions for the labeled
internal standards,
Cx = concentration of the unlabeled PCDD and/or PCDF analyte in the calibration
solution (pg/ml),
THE ACADEMY OF NATURAL SCIENCES

PATRICK CENTER FOR ENVIRONMENTAL RESEARCH
Cqs = concentration of the 13C12-labeled quantitation standard in the calibration solution
(100 pg/ml), and
Calibration data used in the quantitation of detected analytes met the calibration criteria; no
deviations beyond the control limits were observed. The average percent deviation was less than
15%, and no analyte had a percent deviation greater than 25% deviation.
Example Calculations
The concentration of the target analytes and the recovery of the 13C12-labeled quantitation
standards are calculated using the following equations:
Cx = (Ax * Cqs)/ [Aqs * RRF (n)]
% Recovery = (Ax * Cis * 100) / [Ais * Cqs * RRF (m)]
where:
Ax = sum of the integrated ion abundance’s of the quantitation ions for unlabeled PCDDs
and PCDFs,
Aqs = sum of the integrated ion abundance’s of the quantitation ions for the 13C12-labeled
quantitation standards,
Ais = sum of the integrated ion abundance’s of the quantitation ions for the 13C12-labeled
internal standards,
Cx = concentration of the unlabeled PCDDs and PCDFs isomers in pg/µl
Cqs = concentration of the 13C12-labeled quantitation standard in the calibration solution
(100 pg/µl),
Cis = concentration of the 13C12-labeled internal standard in the calibration solution (100
pg/µl),
RRF(n) = Mean relative response factor for the unlabeled target analyte relative to its
13
C12-labeled quantitation standard [RRF(n), with n = 1 to 17], and
RRF(m) = Mean relative response factor for 13C12-labeled quantitation standard relative
to its 13C12-labeled internal standard [RRF(m), with m = 1 to 15].
The sample concentration is calculated using the equation:
Concentration = x * df / wt
where:
Concentration = the concentration of the analyte (ng/g or ng/L);
x = amount of the analyte as found from solving the quadratic equation;
df = dilution factor;
wt = the sample weight in grams or volume in liters.

Laboratory Qualifiers
All of the analytical data have been qualified based on the most recent method detection limits
determined. Concentrations that were less than the LOQ adjusted for sample sizes are qualified
“J” and those analytes not detected are qualified “ND.” Concentrations that exceeded the
calibration limits are qualified “EC”. The concentrations that are determined by analyses of a
diluted aliquot are qualified “D”. If interference is encountered with the quantification of an
analyte due to high concentration of another analyte, the concentration is qualified “I” to denote
this interference.
Analytical Difficulties
The procedural blank for QC batch DX0492 contained no analytes above the LOQ. The
procedural blank for QC batch DX0493 contained no analytes greater than 3 times the LOQ.
Surrogates recoveries were acceptable for all surrogates except 13C-1,2,3,4,7,8,9-HpCDF in
samples C37396 (140%). There were no analytes detected in the samples that were quantified
with that surrogates. No further action was taken. The matrix spike (MS) and matrix spike
duplicate (MSD) recoveries for QC batch DX0492 were acceptable except for 2,3,7,8-TCDD in
the MS and 2,3,4,7,8-PeCDF in the MSD. They were only slightly above the acceptance criteria
and no further action was taken. The matrix spike (MS) and matrix spike duplicate (MSD)
recoveries for QC batch DX0493 were acceptable except for 2,3,7,8-TCDF in both the MS and
in the MSD and 2,3,7,8-TCDD, 1,2,3,6,7,8-HxCDF, 1,2,3,7,8,9-HxCDF in the MS. They were
only slightly above the acceptance criteria and no further action was taken. The recoveries for
2,3,7,8-TCDD and 2,3,7,8-TCDF in the SRM (NRCC Carp-1) were acceptable for both QC
batch DX0492 and DX0493. The 1,2,3,7,8-PeCDD in the SRM for both DX0492 and DX0493
slightly exceeded the acceptance criteria and the MS and MSD are acceptable for this analyte.
The 1,2,3,7,8-PeCDF in the SRM for both DX0492 and DX0493 exceeds the acceptance criteria
by a factor of 10, but the MS and MSD are acceptable for this analyte. The reason for the high
concentration of 1,2,3,7,8-PeCDF in the SRM is not known, but is consistently found for this
SRM by GERG. It however does not affect the sample concentrations as documented by the
acceptable MS and MSD recoveries. Other analyte were acceptable in the SRM or not detected
in any of the samples. No further action was taken. No further variances or difficulties were
observed.
