In some circumstances, assessment of environmental impacts to biota are best understood by
directly evaluating toxicity. IEc has expertise in the interpretation of toxicological
information and has a thorough understanding of the range of
environmental factors that can affect toxicity.
We regularly evaluate and interpret toxicological information in the context of
assessing both impacts to biological natural resources and human health. Similar to
our chemistry-related services, we provide a range of services related to toxicology,
including: design of toxicity testing protocols, oversight and subcontracting of laboratories
that conduct direct toxicity testing using a range of biological species, and analysis
and interpretation of toxicity data. Examples of specific projects in these
- Field collection and use of sediment in toxicity tests to assess
contaminant-related impacts to bivalves, polychaetes, and other standard test organisms.
- Assimilation of toxicity testing information into assessments of
natural resource injury and service losses on a wide range of natural resource damage
- Expert elicitation of uncertainty in the dose-response
function relating mortality with exposure to fine particulate matter (PM2.5).
