Juliska Princz

Manager - Soil Toxicology Laboratory, Biological Assessment and Standardization Section

CURRENT S&T / RESEARCH - Supports Science and Technology with the development, validation and standardization of biological test methods for the toxicological assessment of pollutants in soil

  • Risk assessment of new (microbial, products of biotechnology) substances on Canada’s Domestic Substance List by investigating the pathogenic and toxic potential of these substances to terrestrial organisms in soil
  • Developing standardized toxicity test methods for Canadian boreal forested regions using ecologically-relevant terrestrial organisms
  • Toxic assessments of weathered petroleum hydrocarbon and brine-impacted soils to terrestrial organisms
  • Evaluating the bioaccumulation of metals and organic substances in earthworms, and petroleum hydrocarbons in soil mites


Terrestrial (plants and soil invertebrates) toxicology, including test method development

Research and test validation contributions to the publication of Environment Canada's Biological Test Method Series for terrestrial toxicity testing

Numerous research presentations at over 25 national and international conferences and workshops
