Pesticides Monitoring Journal, Vol. 12, No. 2: 51-59.i1. Butler, P.A. and R.L. Schutzmann. 1978. Residues of Pesticides and PCBs in Estuarine Fish, 1972-76 A. MethodsChemical analyses were performed by the U.S. Environmental Protection Agency Pesticide Monitoring Laboratory in Bay St. Louis, Mississippi.)Briefly with regard to chemical analyses,PCBs, organochlorine pesticides, and organophosphate pesticides were analyzed by Gas Chromotography with Electron Capture Detection (GC/ECD).DGC columns were packed with various combinations of absorbent media.B. Quality Assurance:Information regarding Quality Assurance is presented in: QSamples were collected by the University of Delaware College of Marine Studies. 3Field and laboratory methods used are described in:;1. All fish collected were juveniles less than 1 year old. Polychlorinated Biphenyls (PCBs)2Concentrations are in ug/kg (ppb) wet weight basisAthe following data for the samples from the 3 Delaware estuaries.YearSamplesNo. ofNumberPositiveMaximumResidue of Positive Geomean2. Fish were collected from 3 unspecified estuaries in Delaware. Because the National Pesticide Monitoring Program focused on larger, regionally significant estuaries, and since bivalves from the Delaware Bay and the Delaware Inland Bays had previously$ during the 1972 to 1976 period. been sampled under the Program, it is likely that the Delaware Bay and Delaware Inland Bays were 2 of the 3 estuaries monitoreds4. Sampling was conducted at 6-month intervals in the spring and fall over the period July 1972 through June 1976.5. Eleven separate fish species were analyzed among the 3 Delaware estuaries. Nine species were collected three or more times over}3. Samples were analyzed as whole body composites, with 25 individuals in each sample. Each sample had a field duplicate. iFish tissue residue data are not available for individual samples. Butler and Schutzmann (1978) present PCBs (1) Notes:X1. PCBs were quantitated by comparison with standards of Aroclors 1242, 1254, and 1260.wThe above reference indicates that the recovery range for organochlorines was 75-85%, and for organophosphates, 85-95%.Ave =:second highest nationally among all coastal areas tested.)>(Butler and Schutzmann (1978) identified this average as the 7 Results for individual Aroclors are not available.4504 (2) 2. It is likely but not certain that this sample consisted of whole body juvenile white perch collected from the Chesapeake & Delaware Canal. This supposition is based upon data and information presented in Mearns, et.al. (1988). Specifically, Mearns, et.al. (1988) list a PCB maximum concentration of 4.5 ppm (4500 ppb) for white perch collected in 1972-73 within the C&D Canal and attribute the original data source to Butler and Schutzmann (1978). In a similar manner, Mearns, et.al. (1988) present a maximum PCB concentration of 3.0 ppm (3000 ppb) in Alewife collected from the C&D Canal during the period 1972-73, citing Butler and Shutzmann (1978). Finally, Mearns et.al. (1988) list a maximum PCB concentration of 4.3 ppm (4300 ppb) in white perch and 1.2 ppm (1200 ppb) in Bay anchovy collected in the Delaware Bay during the period 1972-76. Again, Butler and Schutzmann (1978) are cited as the original source of the data and information. 3highest nationally among all coastal areas tested.)Sum of DDD, DDE, and DDTNote:Pesticides (1) 1. In addition to DDD, DDE, and DDT, the samples were also screened for aldrin, chlordane, dieldrin, endosulfan, heptachlor, lindane, methoxychlor, mirex, toxaphen, trifluralin, azinphosmethyl, carbophenothion, DEF, demeton, diazinon, ethion, malathion, parathion, and phorate. Of these, dieldrin was the only one detected in the 57 samples from the 3 Delaware estuaries over the period 1972-76. Dieldrin was detected in 2 samples at an average concentration of 59 ppb. The lower detection limit was 10 ug/kg (ppb) for all pesticidesw except endosulfan (20 ppb); methoxychlor and ethion (30 ppb); mirex, toxaphene, carbophenothion, and DEF (50 ppb). e PCB and Chlorinated Pesticide Contamination in U.S. Fish and Shellfish: A Historical Assessmentc2.

A total of 57 fish samples from the 3 Delaware estuaries were analyzed.Limited information is available which describes the individual samples collected in conjunction with this monitoring effort. Butler and7Schutzmann (1978) do provide the following information: the sampling frame. These nine species included: Alewife, Atlantic Menhaden, Atlantic Silverside, Bay Anchovy, Spot, Weakfish, White Perch, Windowpane% Flounder, and Winter Flounder.
