项目摘要
DESCRIPTION (Verbatim from the Applicant's Abstract): The risk from an
environmental contaminant is estimated with a risk equation involving the
contaminant's concentration and other factors. Because the overall goal of risk
management is to ensure such risks are not intolerably large, we need some way
to backcalculate from constraints on risk mandated by regulation or prudence to
the allowable environmental concentration for the contaminant. It is now well known that the approach used in deterministic assessments of simply inverting
the risk equation to compute the cleanup goal does not work in a probabilistic
assessmnent. Several approaches have been proposed, but none is sufficiently
general. We have developed simple and efficient methods to compute cleanup
goals that satisfy multiple simultaneous criteria in the context of a
probabilistic assessment. The approach can be used with multiple receptors and
with arbitrarily many constraints on percentiles of the target risk. The
proposed research will explore the properties of this approach, conduct case
studies to demonstrate its workability and extend it to more complex problems
involving multiple effects (e.g., the toxicant causes two diseases), multiple
trophic levels (e.g., plankton to shellfish to humans), and eventually to
multiple exposure pathways (e.g., breathing, drinking, dermal absorption), and
multiple potentially synergistic toxicants.
PROPOSED COMMERCIAL APPLICATION:
Commercialization would be in the from of a software library that could be used by software designers as well as end-users to compute the limits on concentrations of environmental contaminants that would yield tolerably low doses in humans under uncertainty and complex dynamics. The ability to compute such limits is needed by risk analysts in public health departments, potentially responsible" industries, and private consulting firms.
