target PAH was calibrated prior to and following sample separations. 
Analytical results from the preparative fractionations were computed 
using external standard response curves. Two fractions were collected 
for analysis—an early, low molecular weight PAH (FB) and chlorinated 
hydrocarbon fraction, and a late high molecular weight PAH fraction (FD). 
These were concentrated to 10 and 50 ul, respectively, and spiked with 
perdeuterated phenanthrene internal standard (110 and 150 ng/ul, 
respectively) for GC/MS analysis. 
Analysis by GC/MS was performed using a Finnigan 4023 system, containing 
a Hewlett Packard 5840B gas chromatograph equipped for capillary analysis 
with direct transfer of the column through the vacuum manifold into the 
ionizer of the MS. All quantitation was based on internal standard; 1 ul 
injection volumes were used. 
Samples of chlorinated hydrocarbon fractions (FB) were reanalyzed by GC/ECO. 
The remaining sample was then diluted to 200 ul in hexane. An expanded 
standard containing additional pesticides was employed. 
Quality control for organics analysis . Quality control for study samples 
consisted of: internal recovery compounds in each sample, instrumental 
quality control, and replicate analysis. The recovery compounds used 
represented the target classes of contaminants ( pesticides, chlorinated 
hydrocarbons, PAH. Mean recoveries (standard error at 95% confidence) 
were: 2-chloronaphthalene—80.3 (4.3%), o,p'-DDE—80.6 (1.8%). Instrument 
quality control procedures consisted of daily blanks and reference 
standards interspersed with study samples. 
In addition to exchange of reference materials, interlab quality control 
included participation in an international PCB interlaboratory comparison 
sponsored by the International Commission for the Exploration of the 
Seas (ICES). The laboratory also participated in the National Oceanic and 
Atmospheric Administration (NOAA) sponsored National Status and Trends 
Quality Assurance Program to measure PCB congeners in fish oil and in an 
U.S. Environmental Protection Agency (EPA)/Centers for Disease Control (CDC) 
project under the Superfund program. 
Results 
Demographic studies. The average shoreside angler was an employed (57.2%) 
male (91.6%) with 12 or more years of education (76.6%). Most were Caucasian 
(68.7%); however, black (8.1%) and Asian (20.9%) fishermen were regularly 
encountered. The anglers ranged widely in age with a large percentage 
falling in the 17-34 year (50.1%) and 35-64 year (35.2%) age brackets. 
Shoreside anglers fished almost as frequently on weekdays (48.8%) as on 
weekends (51.2%), and were most active between the hours of 6:00 p.m. and 
midnight (56.2%). Although anglers fished year round, activity peaked in 
the Autumn (41,8%). More than half the anglers caught nothing (51.7%). 
Among those who did catch fish, most (70.7%) landed fewer than five per 
trip. The five most commonly caught species (based on numbers of organisms)
