Attached is a summary of all the chemistry data for New Bedford Harbor which we have generated to date. The data in this report came from 3 different sets of samples: 1) single preliminary core samples from 13 sites in New Bedford Harbor, 2) triplicate analyses of sediment from the 6 sites which we used in our toxicity testing (plus the reference sediment which we used), and 3) tissue and egg samples from fish exposed to those sediments. Analyses were performed in three ways: 1) selected metals were measured using flame atomic absorption, 2) PCBs were measured as Aro- c1 or 1254 by electron capture gas chromotography, 3) PCBs were also measured as chlorine number congeners and total PCBs by gas chromotography/mass spectrometry (according to the procedures of EPA EMSL, Cincinnati). Draft chemical procedures are available upon request. The values from the triplicate samples are presented both as individual values (tables 2 and 4) and as means (tables 3 and 5). The 6C-MS data from the triplicate analyses are also presented in two different graphical formats. Figs 2-7 are bar graphs showing PCB composition by chlorine number con- gener of the sediments from each station. The composition. by chlorine number congener, of 7 reference Aroclor mixtures <e. g. Aroclor 1254) are included for comparison (fig-s. 8-14). Finally, total PCB and PCB broken down into chiorin* number congeners are plotted vs. statio.n number (figs. 15-25).

Subject: Preliminary chemistry results from New BedfordHarbor studies.
From: David Hansen via Walter Berry
To: Charles Bering.
Attached is a summary of all the chemistry data for NewBedford Harbor which we have generated to date.
The data in this report came from 3 different sets ofsamples: 1) single preliminary core samples from 13 sitesin New Bedford Harbor, 2) triplicate analyses of sedimentfrom the 6 sites which we used in our toxicity testing (plusthe reference sediment which we used), and 3) tissue and eggsamples from fish exposed to those sediments. Analyses wereperformed in three ways: 1) selected metals were measuredusing flame atomic absorption, 2) PCBs were measured as Aro-c1 or 1254 by electron capture gas chromotography, 3) PCBswere also measured as chlorine number congeners and totalPCBs by gas chromotography/mass spectrometry (according tothe procedures of EPA EMSL, Cincinnati). Draft chemicalprocedures are available upon request. The values from thetriplicate samples are presented both as individual values(tables 2 and 4) and as means (tables 3 and 5).
The 6C-MS data from the triplicate analyses are alsopresented in two different graphical formats. Figs 2-7 arebar graphs showing PCB composition by chlorine number con-gener of the sediments from each station. The composition.by chlorine number congener, of 7 reference Aroclor mixtures<e. g. Aroclor 1254) are included for comparison (fig-s.8-14). Finally, total PCB and PCB broken down into chiorin*number congeners are plotted vs. statio.n number (figs.15-25). Higher station numbers generally correspond to agreater distance upstream from the hurricane barrier (seefig. 1).
We have also included a proposal for some PAH work. Inaddition we are planning to do chlorine number congener ana-lysis on tissue samples which have already been analyzed ^o^Aroclor 1254 and selected metals.

Table 7. Concentration (ug/g dry weight) of polychlorinated biphenyls
(PCBs) in sediments from New Bedford Harbor. Analysis was performed by
GC/MS. Concentrations are reported by chlorine number congeners, and as
total PCBs. Values are composites of cores from 9 to 13 Ponar dredge
samples from stations 2 to 14 in New Bedford Harbor; one dredge sample
was analyzed from station 1.
