From page 317...
... The most obvious methods are the same kinds of direct and indirect methods used in human exposure assessment, including measurements of environmental contaminant concentrations in media to which organisms are exposed, measurements of uptake or body burden, and measurements of biochemical markers correlated with contaminant exposure. Larger-scale tools for exposure assessment include remote sensing (habitat, productivity, and albedo)
