Biomonitoring

Share this

Chemistry Matters provides the expertise and experience to design reliable sampling strategies, conduct field sampling programs, and interpret and analyze the chemical results. Chemistry Matters can design defensible and effective studies to assess environmental impacts and exposure to contaminants in wildlife and humans.

As part of our process, Chemistry Matters stresses the importance of both control samples and reference samples / populations for successful monitoring programs.

Biomonitoring Projects

From measuring contaminants in fish and humans to epidemiological studies, Chemistry Matters has extensive experience with the sampling, chemical analysis, and interpretation of chemistry data as part of large biomonitoring projects. Previous projects have included:

  • Fish biomonitoring for potential PAH exposure after oil spill
  • Fish biomonitoring for dioxins near Agent Orange site
  • Human biomonitoring for PCBs and dioxins near current and former industrial areas

Chemistry Matters has also participated in litigation support for class action lawsuits regarding contaminant concentrations in human exposure.

Research Publications

The Chemistry Matters team has authored a number of biomonitoring-related research publications on the assessment and impact of contaminants in humans and wildlife.

What is biomonitoring?

Biomonitoring is the measurement and interpretation of the amount of chemicals in fish, wildlife or the human body.  It assesses the exposure of the organism to contaminants.

What is the most important part of biomonitoring?

In order to interpret biomonitoring data, you need to know what you are going to compare to in order to assess the concentrations of contaminants measured. This can be previous studies or proper references/controls built into your study.

Without a good comparison, biomonitoring data is just a number. The proper comparison gives it context to whether concentrations are elevated or normal.

Are there good reference ranges to assess human exposure?

There are numerous scientific studies published in scientific literature but for humans exposure, the best remains the Centers for Disease Control and Prevention’s work on the National Health and Nutrition Examination Survey (NHANES).

Canada has also started a biomonitoring program for its population called the Canadian Health Measures Survey. This survey will also be a valuable tool for comparison and reference.

What is the NHANES?

NHANES is a program that collects health information (information and measurements) from individuals of the United States population along with blood and urine samples which are sent for chemical analyses.
