ABSTRACT

To support natural resource damage assessment (NRDA) in response to the Deepwater Horizon (DWH) 

oil spill in the Gulf of Mexico, a large number of coastal sediment and tissue (i.e., oysters) samples 

have been collected outside of the spill zone to define baseline environmental conditions prior to being 

exposed to oil. Analysis of oiled sediments and oil-exposed oysters will continue for the foreseeable 

future. To support these efforts, NOAA will require additional analytical laboratories to perform

NRDA sample analyses To compare the data among these laboratories, inter-laboratory comparison 

studies have been initiated with the results from the first exercise, marine sediment QA10SED01 

reported here. In this exercise, selected polycyclic aromatic hydrocarbons (PAHs), alkylated PAHs, 

hopanes, and steranes were determined in the exercise material, which consisted of wet frozen 

sediment, and in SRM 1941b Organics in Marine Sediment. The results from this first exercise are 

reported along with a summary of the analytical methods used. 

INTRODUCTION

On April 20, 2010, a fatal explosion, fire, and sinking of BP’s Deepwater Horizon drilling rig occurred 

approximately 40 miles off the Louisiana coast. The disaster resulted in the discharge of tens of 

thousands of barrels of oil per day from the seafloor into the Gulf of Mexico. In what has become the 

worst offshore oil spill in U.S. history, a wide expanse and variety of natural resources have become 

exposed and potentially impacted by oil and other consequences of the spill. Under the Oil Pollution 

Act, those responsible for an oil spill are liable for clean-up and for natural resource damages. Several 

federal and state agencies are conducting a natural resource damage assessment (NRDA) to determine 

what resources have been injured and what uses of the resources have been lost due to the spill. 

To support this NRDA, the trustees and BP’s representatives have been collecting and analyzing tens of 

thousands of environmental samples to characterize both pre-spill and post-spill environmental 

conditions. A broad range of sample types have been collected including oil in various forms, water,

sediment, and biota. For the foreseeable future, subsequent sampling and analysis will be required. In 

addition, numerous other entities have collected environmental samples for hydrocarbon analysis and 

submitted them to different laboratories throughout the country. 

In the past the National Institute of Standards and Technology (NIST) has helped benchmark and 

improve the quality of analytical data gathered on the marine environment by administering 

interlaboratory comparison exercises. To compare the data among the many laboratories analyzing 

samples from this spill, the National Oceanic and Atmospheric Administration (NOAA) has requested 

that NIST coordinate interlaboratory comparison studies with sediment, crude oil, and bivalve tissue

being the three matrices of interest. These studies are performance-based with each laboratory using its 

current methods for analysis of similar matrices that it would use for its program customers. The target 

analytes for each study are selected polycyclic aromatic hydrocarbons (PAHs), alkylated PAHs, 

hopanes, and steranes. More than three dozen laboratory facilities were contacted by NOAA and 

invited to participate in the studies; for all three matrix studies a large number of laboratories agreed to 

receive samples and report their analytical results to NIST.

The data received from 33 laboratories for the marine sediment QA10SED01 are summarized in this 

report along with summaries of the analytical methods used by each laboratory. Numerical indices, z-
4

and p-scores, are used to assess and track laboratory performances for accuracy and precision, 

respectively, and to provide a mechanism for assessing the comparability of data produced by the 

participating laboratories for the target analytes. 

SOURCE OF MATERIAL

The sediment material used for the exercise consisted of the fine-sieved fraction remaining from the 

preparation of SRM 1944 New York/New Jersey Waterway Sediment [1]. The sediment was collected 

from six sites in the vicinity of New York Bay and Newark Bay in October 1994 using an epoxy-coated 

modified Van Veen-type grab sampler designed to sample the sediment to a depth of 10 cm. A total of 

approximately 2100 kg of wet sediment was collected from the six sites. The sediment was freezedried, sieved (nominally 250 μm to 61 μm was used for SRM 1944 and <250 μm was used for 

QA10SED01), homogenized in a cone blender, radiation sterilized at an estimated minimum dose of 

3.2 megarads (

60Co). The fine-sieved fraction (<250 μm ) was wetted by the addition of approximately 

47% (mass fraction) of HPLC-grade water. For the interlaboratory study, the participants received wet 

frozen sediment. The mean water composition was 47.4% with a standard deviation of 0.2%.

SAMPLE DISTRIBUTION

Three jars of wet frozen sediment were distributed to each of 40 laboratories in August and September

2010. Each laboratory was requested to analyze three samples of Marine Sediment QA10SED01 and at 

least one or more samples of SRM 1941b Organics in Marine Sediment using their laboratory's and/or 

program's analytical protocols, for determination of the concentrations (mass/mass [dry-mass basis]) of 

the parent polycyclic aromatic hydrocarbon (PAH) compounds, alkylated PAH compounds, hopanes, 

and steranes currently being determined in their laboratory. 

The instructions including the list of target analytes sent to participants are attached in Appendix A.

EVALUATION OF EXERCISE RESULTS 

Establishment of the Assigned Values

Laboratory data submission: Each participating laboratory was asked to submit data from three 

replicate determinations of the “unknown” material QA10SED01 and was requested to report results of 

concurrent analyses of NIST SRM 1941b Organics in Marine Sediment. Laboratories were requested 

to report these results to three significant figures and to provide brief descriptions of their extraction, 

cleanup, and analytical procedures. 

Determination of laboratory analyte means: For each laboratory, the laboratory analyte mean of the 

three sample results (S1, S2, and S3) was calculated for each analyte. Non-numerical data were treated 

as follows: A mean "<value" was used when three "<values" were reported; NA (not 

analyzed/determined) was used for three reported NAs; and, if the reported results were of mixed type, 

e.g., S1 and S2 were numerical values and S3 was reported as “<value”, the two similar "types" were 

used to either determine the mean or to set a non-numerical descriptor.
5

Determination of assigned values: The assigned values are the means of the acceptable data as defined 

here. For a particular analyte, the performance on the reference material, SRM 1941b, was initially 

deemed acceptable for the purpose of this exercise if the laboratory result was within 30 % of the upper 

and lower limits of the confidence interval for analytes listed in the Certificate of Analysis for SRM 

1941b [2]. The criterion of 30 % is the same as the one that was used for the National Oceanic and 

Atmospheric Administration (NOAA) Mussel Watch and National Status and Trends Quality 

Assurance Programs [3]. If a laboratory demonstrated acceptable performance on a particular analyte 

in the reference material, that laboratory’s results for that analyte in the corresponding “unknown”

exercise material was then used in the calculation of the analyte’s exercise assigned value, unless it was 

deemed an outlier. For evaluation of potential outliers, statistical tests and expert analyst judgment

were used after viewing both normal and log-normal plots of the data. This judgment utilized 

knowledge of potential coeluters based on the laboratory's reported methods. In instances for which the 

analyte concentration was below the detection limit of most participating laboratories, no exercise 

assigned value was calculated. In data sets where a number of laboratories report results as "not 

detected" at various detection limits, there is no consensus as to what numerical value should be 

assigned to these results in the computation of consensus means and other values.

Reported Results

Laboratories were assigned numerical identification codes in order of receipt of data with the exception 

of the two NIST laboratories which are Lab 1 and 32 in this exercise. The laboratory mean replicate 

data are shown in Tables 1 to 3 for QA10SED01. Included in the means tables are the exercise 

assigned mean values and the standard deviation of the assigned mean values along with the exercise 

assigned median values. Summaries of the methods used by each laboratory are in Appendix B, and

notes included by a laboratory with its data are listed in Appendix C. In Appendix D, charts of the 

mean numerical results reported by each laboratory for each analyte are shown for the exercise material 

and the corresponding reference material, SRM 1941b. 

Performance Scores

The exercise coordinators recognize that different environmental monitoring programs have different 

data quality objectives and needs. The acceptability of the results submitted by a particular laboratory 

will be decided by the individual program(s) for which the laboratory provides data. Typically, each

program will use these exercise results in conjunction with the laboratory's performance in the analysis 

of certified reference materials and/or control materials, and of other quality assurance samples. These 

exercise results are exhibited in a number of ways in this report to facilitate their use by most 

environmental monitoring programs in their acceptability assessments. 

IUPAC guidelines describe the use of z-scores and p-scores for assessment of accuracy and precision in 

intercomparison exercises such as those described in this report. These indices assess the difference 

between the result of the laboratory and the exercise assigned value and can be used to compare the 

performance of different laboratories among the participants on different analytes and on different 

materials.

Accuracy Assessment (z-score)
6

z-score = (bias estimate)/(performance criterion) = (x - X)/ σ

where x is the individual laboratory result, X is the "Exercise Assigned Value,” and σ is the target value 

for standard deviation.

As described in the IUPAC guidelines, the choice of σ is dependent upon data quality objectives of a

particular program. It can be "fixed" and arrived at by perception, prescription, or reference to 

validated methodology (e.g., σ = 0.025 X; X is the exercise assigned value,), or it can be an estimate of 

the actual variation (e.g., the calculated sample standard deviation, s, from the exercise data). The 

"fixed" performance criterion is more useful in the comparison of a laboratory's performance on 

different materials while the use of the actual variation may be more useful within a given exercise, for 

example, if the determination of a particular analyte is exceptionally problematic. The measurement of 

analytes in this study is not particularly problematic.

 

We have calculated and reported z-scores using the fixed performance criterion for each analyte for 

each laboratory using "25 % of the exercise assigned value" as the fixed target value for standard 

deviation for this program. The use of z-score (25 % X) is also taken from the the NOAA Mussel 

Watch and National Status and Trends Quality Assurance Programs. The z-scores calculated for these 

exercises can thus be interpreted as shown in the following examples:

z-score (25 % X):

+1  laboratory result is 25 % higher than the assigned value

-2  laboratory result is 50 % lower than the assigned value.

From a scientific point of view, IUPAC does not recommend the classification of z-scores but allows 

that a common classification is:

z  2 Satisfactory

2 < z < 3 Questionable

z  3 Unsatisfactory.

This classification has been deemed acceptable within the measurement community. 

Tables 4 through 6 summarize the z-scores (25 %) for each laboratory for each reported analyte in 

QA10SED01. 

In addition, Tables 7 through 9 summarize the percent differences from the consensus values with color 

coding to reflect laboratories using similar extraction methods, and Tables 10 through 12 summarize 

the percent differences from the consensus values with color coding to reflect the differences in use of 

surrogates, internal standards, and recovery corrections among the laboratories. 

Precision Assessment (p-score)

p-score = σlab / σtarget

For the calculation of p-scores for this program, the σ values used are coefficients of variation (CV 

calculated as relative standard deviations) with the current target σ (CV) for the three replicates being 
7

15 %. Tables 13 through 15 summarize the relative standard deviations (RSDs) calculated from the 

three concentrations reported by the laboratory for each analyte quantified while Tables 16 through 18 

summarize the p-scores (15%). 

 

DISCUSSION

NOAA’s NRDA office solicited laboratories involved in the analysis of samples shortly after the DWH 

disaster for their interest in participating in this interlaboratory study for analytes of interest in 

sediment. The participation by the laboratories was voluntary, and samples of QA10SED01 were 

provided free of charge. Laboratories were provided with information for ordering SRM 1941b (See 

Appendix A). Interested laboratories were requested to quantify selected PAHs, alkylated PAHs (some 

individual and some as groups), and biomarkers (hopanes and steranes) in three aliquots of 

QA10SED01 and SRM 1941b using their laboratories’ analytical protocols for these analyses. A total 

of 40 laboratories received samples of which 33 laboratories submitted data. The 33 participating 

laboratories are listed in alphabetical order in Appendix E. One laboratory (33) submitted data using 

two analytical methods. The results using gas chromatography with mass spectrometric detection 

(GC/MS) are reported in the data tables and shown in Appendix D while the data for the PAHs

quantified using GC/MS/MS are reported in the notes (Appendix C) but not used in the calculation of 

the consensus values. 

Tables 1 through 3 summarize the laboratory means and exercise assigned values for the PAHs, 

alkylated PAHs, and biomarkers (hopanes and steranes), respectively. The consensus value for a given 

compound in QA10SED01 was derived by combining data where corresponding values in SRM 1941b 

were within 30% of the expanded uncertainty of the SRM value. In the absence of a corresponding 

SRM value, individual results were screened using outlier tests and included in the consensus value if 

values were shown not to be statistical outliers. Appendix D contains the charts of the QA10SED01 

and SRM 1941b data by analyte. In these charts, the analytes that are not included on the Certificate of 

Analysis for SRM 1941b are shown with no target value. A number of laboratories are reporting values 

below the certified and reference values for the analytes in SRM 1941b. So as not to eliminate too 

many data points in the calculation of the exercise assigned values for QA10SED01, a less stringent 

criterion of 50%, as opposed to 30%, below the confidence interval for the SRM data was used for 

screening the data for the majority of the analytes. However, the two NIST data sets (Lab 1 and Lab 

32) as well as data from some laboratories that have participated in previous sediment interlaboratory 

studies as part of the NIST Intercomparison Exercise Program for Organic Contaminants in the Marine 

Environment agreed with the certified and reference concentrations for the majority of the analytes 

characterized in SRM 1941b thus suggesting some issues with data from laboratories that failed to 

report agreement with the certified and reference values for SRM 1941b.

In an effort to determine what could be causing the differences, the laboratory’s % difference from the 

exercise assigned values for QA10SED01 was color coded based on extraction method (Tables 7, 8,

and 9 for PAHs, alkyl PAHs, and biomarkers, respectively) and based on quantitation method (Tables 

10, 11, and 12 for PAHs, alkyl PAHs, and biomarkers, respectively). No general statements can be 

made about the extraction method, other than it was noted that the one laboratory that used QuEChERS

as an extraction method reported low values for all of the analytes that it reported. With only one 

laboratory using this method, it is not possible to determine if the low result by the QuEChERS method 

was method- or lab-related. Similarly, no general statement can be made on the use of surrogates 
8

versus internal standards and recovery correcting versus not recovery correcting in relationship to 

agreement with the consensus value. 

The spread in the PAH data for QA10SED01 among the laboratories is highest for naphthalene, 

acenaphthylene, benzo[b]fluorene, benzo[j]fluroanthene, cis/trans decalin, benzothiophene, and 

naphthobenzothiopene. The alkylated PAH data show even more spread among the laboratories, 

particularly for the C1 to C4 phenanthrenes, C1 to C4 fluoranthenes, and C1 to C4 naphthothiophenes. 

It is interesting to note that for the laboratories who reported 1-methylnaphthalene and 2-

methylnaphthalene as well as C1-naphthalenes, generally the reported values for C1-naphthalenes were 

lower than the sum of the 1-methyl- and 2-methylnaphthalene. Fewer laboratories reported data for the 

selected biomarkers with the largest spread in the data seen for 17α(H), 21β(H)-30-norhopane and 17α, 

21β(H)-hopane. Laboratory 29 (see notes in Appendix C) pointed out some possible nomenclature 

issues for the hopanes which may have caused confusion. These issues will be clarified in future 

studies. 

The majority of the z-scores based on 25% (Tables 4 through 6) are within ± 2 while the majority of the 

p-scores based on 15% (Tables 16 through 18) are within ± 1. This indicates that the laboratories are

internally consistent, but there is still a fair amount of spread among the laboratories. 

It is important to evaluate the non-quantitative results reported by each laboratory as well. Although 

these results are not easily presented or numerically evaluated, they are included in Tables 1 through 3 

of this report. The laboratory and its data users should closely examine these non-quantitative results. 

Decisions based on false negative or false positive results from a laboratory can lead to significant 

environmental and/or economic consequences. Some laboratories reported detection limits in this 

sediment material that may be too high for the data quality objectives and needs of their program(s), 

and these issues should be assessed as well.

Intercomparison exercises provide an important mechanism for assessing the comparability, accuracy, 

precision, and reproducibility of data being produced by the participating laboratories. Exercise 

materials similar in matrix, form, and analyte concentration to typical samples routinely analyzed by 

the laboratories are most useful for demonstrating the level of comparability and for revealing potential 

problem areas. 

Minimizing the among-laboratory biases so that the analytical variability is significantly less than the 

field sampling variability should be an achievable goal in environmental monitoring.

APPENDIX A Instructions Sent to Laboratories

Interlaboratory Analytical Comparison Study to Support Deepwater Horizon Natural Resource 

Damage Assessment

Intercomparison Exercise: Marine Sediment QA10SED01

Description of Materials and Instructions

Intercomparison Exercise Materials:

Each of the three jars contains approximately 19 g (wet basis) of Marine Sediment QA10SED01. This 

wetted sediment was prepared from material collected from the northeastern section of the US coast 

and then freeze-dried, ground sieved, and radiation-sterilized. This material was not enriched or 

spiked. Each 2-oz clear glass jar has a Teflon-lined screw cap and is labeled with an individual jar 

number as well as the above name.

In addition, three concurrent analyses of SRM 1941b Organics in Marine Sediment are recommended. 

This material can be obtained from the NIST Standard Reference Materials Program ($652/50 g (drymass basis). See the following link for information on ordering on-line: https://wwws.nist.gov/srmors/view_detail.cfm?srm=1941B.

Storage of Materials:

Marine Sediment Material. The Marine Sediment QA10SED01 material should be stored in the dark at 

temperatures of -15  ̊C or lower. If only a portion of the contents of a jar is used, that jar should be 

tightly closed immediately after removal of a subsample to preserve the integrity of the remaining 

material for later analysis. 

Instructions for Use:

You are to analyze Marine Sediment QA10SED01 and SRM 1941b using your laboratory's and/or 

program's analytical protocols, for the concentrations (mass/mass [dry-mass basis]) of the parent 

polycyclic aromatic hydrocarbon (PAH) compounds, alkylated PAH compounds, and biomarkers 

currently being determined in your laboratory. A target list of compounds are presented in the 

following Table; however, participants do not need to quantify all of these compounds and can add 

additional compounds when reporting data. 

The percentage of water in Marine Sediment QA10SED01 should be determined so that the results can 

be reported on a dry basis. You should have received sufficient material so that you can perform 

separate determinations for the water content if you do not dry your sediment samples prior to analysis. 

The amount of material used for each analysis should correspond to the amount (wet basis) of marine 

sediment that you would typically analyze as prescribed in your protocols. Prior to removing an aliquot 

of Marine Sediment QA10SED01, you should thaw the sample in the jar and then stir or otherwise 

mix it thoroughly. 
43

You should analyze three samples of Marine Sediment QA10SED01 and at least one or more samples 

of SRM 1941b using your protocol for marine sediment samples. If time allows, we are asking that 

you analyze one sample of Marine Sediment QA10SED01 and one sample of SRM 1941b with one 

batch of laboratory samples; analyze a second sample of each material with another batch; and the third 

sample with yet another batch. This will allow a more realistic assessment of laboratory precision over

a longer term than the assessment obtained when a laboratory places all three samples in the same 

extraction and cleanup batch and the resulting extracts are analyzed using the same calibration curve, 

etc. 

Reporting of Results:

Please report one result, as if three figures were significant, for each of the analytes quantified in each 

of the three replicates of the Marine Sediment QA10SED01 and of SRM 1941b. Report results in units 

of ng/g dry-mass basis. Report the date of measurement of each sample in the requested m/d/y format. 

Also, report the results of your percentage water determinations of Marine Sediment QA10SED01.

If you know that a target or non-target compound is interfering (coeluting) with the determination of a 

target analyte, please identify this issue by qualifying the data and note the data qualifier used at the 

bottom of your table of results. Please note that any changes you make to the column or row headings 

within the tables will not be seen by the coordinators because only the table entries and comments at 

the bottom of the tables are automatically transferred to the exercise database.

We prefer that concentration values be reported for each analyte determined. If the measured 

concentration is below your typical reporting concentration for an analyte in a particular matrix, you 

can report the number and list the appropriate detection limit, quantification limit, etc. at the bottom of 

the data table. However, if you need to report non-numerical data please use the following 

conventions:

NA "Not analyzed", "not determined"

<"value" "Less than specified concentration", e.g., <8 ng/g

Other "Other"; add note of explanation at end of data table, e.g., interference

DL "Below detection limit" may be used, however, <"value" is preferable

Do not use negative numbers or parentheses to indicate "less than detection limits". 

The attached file is an EXCEL file, QA10SED01.xls. If you have any software/hardware conversion 

problems, please contact Michele Schantz. The data file templates also include places for you to list the 

surrogate/internal standards and type of calibration curve used, and to provide a brief description of the 

analyses. Please do not add spaces before entering numbers in the table cells and enter them as 

"numbers" not as "labels". Please do not insert any columns or rows within the table in the data file. If 

you wish to include additional data and/or other information or comments, you may add it to the bottom 

of the data table in the attached file. 

Submit your results by September 24, 2010 as an attached file via e-mail to:

3 Analysis of SRM 1941b was not performed.

Samples 158 and 167 were extracted in one batch on 9/07/2010. Sample 183 was extracted 9/08/2010.

The concentration range of 5-80 ng/uL for the calibration curve represent on column concentrations. 

The range in final reporting concentration is 4000 ng/g dry mass to 320000 ng/g dry mass.

Concentrations reported as <4000 ng/g dry mass represent < quantitation limit.

Values reported below 4000 ng/g dry mass are below the quantitation limit and are considered estimated.

4 T=Reported value is less than the reporting limit (RL). Result is estimated.

We normally extract 25 grams of sample, since less was provided the RLs were raised.

Not enough sample was submitted for TOC analysis.

5 J values will be reported as <100

6 1-methylphenanthrene has an interferent peak

Benzo(k)fluoranthene co-elutes with benzo(b)fluoranthene

Dibenzofuran has an interferent peak

7 * - Analytes coelute and cannot be resolved under the chromatographic conditions used

** - The analytes could not be resolved from the Sulfur interference

X - Results may have a high bias due to interference from Sulfur

16 Other: Reported Chrysene concentration equals combined detected Chrysene and Triphenylene concentration (we do not report them separately).

Reported Benzo[k]fluoranthene concentration equals combined detected Benzo[j]fluoranthene and Benzo[k]fluoranthene concentration (we do not report them separately).

17 NA = Not analyzed for

Other = Matrix interferencs precluded identification/quantitation of target analyte

18 Any values under 100 ug/Kg weight weight are below the reporting limit and should either not be reported or reported with qualifiers. 

19 Quantitations for 1-Methylphenanthrene, C2-Fluorenes and C1-Phenanthrenes are not certain due to interference with sulfur peak.

Due to sulfur interference, result for 1-Methylphenanthrene in QA10SED01/Sample 2 is uncertain.

No peak found for 1-Methylphenenthrene in SRM1941b/Sample 2 due to large sulfur peak. 

No C2-Fluorenes peaks detected in QA10SED01/Sample 2 due to sulfur interference.

No C2-Fluorenes peaks found in SRM1941b/Sample 2 due to large sulfur peak. 

No C1-phenanthrenes/anthracenes peaks found in SRM1941b/Sample 2 due to large sulfur peak. 

QA10SED01: Method Detection Limit - 75 ng/g; Practical Quantitation Limit - 300 ng/g

SRM 1941b: Method Detection Limit - 21 ng/g; Practical Quantitation Limit - 82 ng/g

The Method Detection Limit for each alkyl homologue series is assigned twice the method detection limit of its representative compound used for quantitation.

Benzo[b ]fluoranthene and Benzo[k]fluoranthene results reported from Agilent 5973 MSD/6890GC; Phenomenex ZB-5MS column, 30m length, 0.25mm id, 0.50um film thickness

Our current procedure uses 30 grams of sediment sample to 1 mL final volume. For the first sample of QA10SED01, we tried to use 12 grams, but 

 determined the 5 x dilution was required due to heavy matrix effects. As a result, 5 grams to 1 mL was used for the remaining two samples.

*** - Analyte coelutes with one of the other isomers of Benzofluoranthene. Efforts are being made to confirm which isomer it
