Juliska Princz

Manager - Soil Toxicology Laboratory, Biological Assessment and Standardization Section

CURRENT S&T / RESEARCH

Supports Science and Technology with the development, validation, standardization and application of biological test methods for the toxicological assessment of pollutants in soil

  • Risk assessment of new and existing (micro-organisms, chemicals and nanomaterials) substances on Canada’s Domestic Substance List by investigating the toxic potential, persistence and bioaccumulation of these substances to terrestrial organisms in soil
  • Developing standardized toxicity test methods for Canadian boreal forested and wetland regions using ecologically-relevant terrestrial organisms
  • Toxic assessments of weathered petroleum hydrocarbon and brine-impacted soils to terrestrial organisms
  • Support to soil guideline development through the evaluation of pollutants in soil and their effect on terrestrial organisms

PROFESSIONAL ACTIVITIES / INTERESTS

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
