Research Investigations

The experience of TRE researchers extends well beyond whole effluent toxicity (WET) and related tests.

TRE Environmental offers a variety of ecotoxicology assessment programs that capitalize on standardized and non-standardized studies on aquatic plants and animals, sediment-dwelling organisms and terrestrial species to generate unique and often ground-breaking methods and results. Some examples of these programs include Water-Effect Ratio studies to explore site-specific water quality standards, product registration studies under Good Laboratory Practices (GLP) following harmonized ASTM, OPPTS or OECD guidance, and toxicity method development resulting in new standardized techniques on key indicator species. Examples of research projects completed by TRE researchers include:

  • Assessment of selenium exposure in salmonids via aqueous, dietary, and maternal transfer
  • Water-Effect Ratio studies with different metals including copper, silver, zinc, and lead
  • Development of a sediment test method using juvenile native anurans (e.g., Leopard frog)
  • Long-term acute and growth effects of boron to emergent macrophytes (e.g., Sagittaria, Saururus, Peltandra)
  • Investigation of factors affecting the acute response of brine shrimp (Artemia) to bromide
