Estimating contaminant transport by biological vectors

Abstract At industrial or urban hazardous waste sites with little or no ecological attributes at risk within their own boundaries, the potential for biotic vector (a target species and/or its predators) transport of potentially toxic quantities of contaminants to previously uncontaminated areas may merit consideration. A simple model is described which permits rapid calculation of a probability for contaminant load dispersal in terrestrial biotic vectors. This model provides a readily applicable, structured methodology to assess the potential for significant biota transport pathways prior to considering field investigations.
