Title: Modelling bioaccumulation of organic pollutants in fish with an application to pcbs in lake ontario salmonids

Abstract

A model describing passive accumulation of organic chemicals from the aqueous environment and contaminated food in fish is developed. The model considers both biological attributes of the fish and physicochemical properties of the chemical that determines diffusive exchange across gill membranes and intestinal mucosa. Important biological characteristics addressed by the model are the fish's gill morphometry, feeding and growth rate, and fractional aqueous, lipid, and nonlipid organic composition. Relevant physicochemical properties are the chemical's molar volume and noctanol/water partition coefficient (Kow), which are used to estimate the chemical's aqueous diffusivity and partitioning to the fish's lipid and nonlipid organic fractions, respectively. The model is used to describe and to analyze the bioaccumulation of polychlorinated biphenyls (PCBs) in Lake Ontario alewife (Alosa pseudoharengus), coho salmon (Oncorhynchus kisutch), rainbow trout (Oncorhynchus mykiss), brown trout (Salmo trutta), and lake trout (Salvelinus namaycush).

  • Lake trout and sediment data were used to define the biota-to-sediment ratio (BSR) for hydrophobic organic chemicals (HOCs) in Lake Ontario, including 2,3,7,8-substituted polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs). The BSRs for bioaccumulative PCDD/PCDFs were found to be approximately two orders of magnitude (i.e., 100x) lower than for other HOCs of similar hydrophobicity. To evaluate this difference, a modeling framework is applied which accounts for the significant processes affecting BSR: bioaccumulation, partitioning, and sediment-water chemical distribution.
  • A long-term laboratory exposure of lake trout to Lake Ontario sediment and smelt (food chain) provided comprehensive bioaccumulation relationships for 2,3,7,8-TCDD. The laboratory exposure was designed to investigate the rates of TCDD uptake via water, sediment, and food under simulated Lake Ontario conditions. Innovative methods of preparing sediment, dosing sediment, preparing food and feeding the fish were developed. Results indicated that bioaccumulation of 2,3,7,8-TCDD occurs primarily through the food chain and secondarily through contact with contaminated sediment. The water exposure route, even under simulated equilibrium conditions, and low suspended solids concentrations did not appear to make a significant contribution tomore » 2,3,7,8-TCDD bioaccumulation.« less
  • There are approximately 2.3 million hectares of cropland in New York. Cultivated organic soils comprise about 12,000 hectares or 0.5% of the total cropped land. The organic soils are used exclusively for intensive vegetable production with onions being the primary crop. About 50% of these soils are located within the Lake Ontario drainage basin. A comprehensive field study was conducted to evaluate the yield response of onions across a broad range of N, P, and K fertilizer inputs and to correlate the level of response with soil testing parameters. A primary objective was to develop an estimate of P lossmore » in drainage water to the Lake Ontario drainage basin and how this loss is influenced by P fertilizer management.« less
  • Concentrations of trace metals and PCBs in six species of fish, zooplankton, macrobenthos, sediment, and water were studied in Crab Orchard Lake, Williamson County, Illinois. Eleven sites were chosen throughout the lake, including one site (site 10) near an abandoned dumpsite of a former electrical transformer manufacturing facility. PCB levels in the selected components from site 10 were considerably higher than the other sites. Thirty-eight percent (17/45) of fish fillets from various species at this site exceeded the 2.00 mg/kg FDA guideline for PCBs. PCB concentrations in fish were variable, and little relationship existed between age or size and PCBmore » concentrations in most species. Common carp and channel catfish had higher PCB levels than the other species examined. Trace metals were low in fish and other components analyzed and were comparable to literature values for the midwestern United States. Mercury was the only trace metal to exhibit a significant positive relationship with age or size of fish. Mercury was also the only trace metal to exhibit biomagnification.« less
  • Cultivated mucklands in western New York State were investigated as a nonpoint source of phosphorus to Lake Ontario. The 70,500-ha Oak Orchard Creek watershed, which drains to Lake Ontario, was selected for the study area. It is located in Genesee and Orleans Counties, New York, and contains 3250 ha of heavily fertilized muck cropland on which predominantly vegetable crops are grown. The creek was monitored at several sites from May 1984 through April 1985 to determine the role of the mucklands in annual phosphorus loading to the lake. At an upstream site which drained approximately 10,200 ha, including the majoritymore » of the muck cropland, the creek load was 18,000 kg of total phosphorus with 75 percent of it as dissolved reactive phosphorus.« less
