Overview of models for estimating contaminant exposure associated with home-grown plant and animal products
- Oak Ridge National Lab., TN (United States). Center for Risk Management
Exposure to environmental contaminants through the consumption of home-grown plant and animal products can be a significant pathway for human health risk assessments at hazardous waste sites. Because empirical data are generally not available, contaminant concentrations in plant and animal tissues are often estimated using species and contaminant-specific biotransfer factors. Often this type of approach can produce a high degree of uncertainty in the ultimate estimation of human health risk. In this study, the authors present a methodology for identifying appropriate uptake/exposure models. In addition, they provide an overview of models for estimating tissue concentrations in home-grown leafy vegetables, fruits, grains, beef, milk, poultry, eggs, swine, and fish. Further, they discuss the application of these models using parameter distributions rather than point values in order to decrease the degree of uncertainty of human health risk assessments that evaluate contaminant exposure through home-grown products.
