Fish in River Biota Tissue Analysis Pace AnalyticalBiota analysis is the determination of the levels of accumulation of toxic substances in plant and animal tissues. The determination of toxic residues in organisms populating a contaminated area is an important part of the ecological risk assessment process. Biological samples may be an indicator of contamination that is affecting the food chain and possibly humans.


The analysis of tissues is significantly more challenging than the analysis of water or soil. We have developed propriety methodologies for tissue extraction and analysis to insure accurate measurement of persistent contaminants in these matrices. Because much of this work takes place at impacted wetlands and waterways, related methods such as low-level Mercury testing by method 1631 and AVS/SEM are also offered. When risk assessment calls for analytical work that goes beyond established methodology, the Pace® Biota Laboratory offers method development for non-standard, site-specific substances.

Questions About Biota Analysis?

Pace® Analytical Services has more than 20 years of experience in the analysis of biological tissues. We routinely analyze fish, amphibians, birds, mammals, and plants for environmental contaminants. Parameters include Metals, PCB Aroclors, PCB congeners, Dioxin/Furans, Organochlorine Pesticides, and other organics.


The Biota Laboratory’s range of matrices includes but is not limited to the following:

  • Fish and amphibians
  • Animal tissue and target organs
  • Plant Life and Insects
  • Sediment and sediment dwelling macroinvertebrates
  • Birds and bird eggs
  • Rodents for hantavirus


The Pace® Team combines the talents of experienced chemists, project managers, sampling technicians, and dedicated product and program managers, to assist in the selection and application of appropriate sampling strategies and provide support on the most demanding projects.
