Biomonitoring of Human Exposure to Environmental Contaminants

Assessing exposure of humans (or wildlife) to environmental contaminants is completed by biomonitoring programs.  These programs start with the collection of samples which are then analyzed for generally very low concentrations of contaminants.  These programs require strong experimental design to provide the required data quality measures for validation.  Once collected and data has been received interpretation depends on comparison of the concentrations measured in your target population being compared to good reference samples or concentrations .  This can be accomplished for human biomonitoring studies by using the NHANES database from the Centres for Disease Control and Prevention as reference.  We are uniquely qualified to complete these projects having worked at the CDC and having produced data for the NHANES database.

We specialize in the design and proper interpretation of biomonitoring data to provide the most accurate interpretation of the results which allows the right conclusions regarding exposure to be achieved.

We have worked with numerous clients in the experimental design, laboratory data validation, and statistical data interpretation of contaminant concentrations in human exposure assessments as part of research programs, epidemiological studies as well as litigation support for class action lawsuits.
