Tire particles are of concern as a stressor due to the combination of their chemical
constituents, high emission rates, and global distribution. Once in the environment, they will …

Naphthenic acids (NAs) are constituents of oil sands process-affected water (OSPW). These
compounds can be both toxic and persistent and thus are a primary concern for the ultimate …

Mechanistic toxicology approaches represent a promising alternative to traditional live
animal testing; however, the often-noted uncertainties concerning the linkages between …

Complex mixtures of chemicals present in groundwater at legacy-contaminated industrial
sites can pose significant risks to adjacent surface waters. The combination of short-term …

Unconventional oil production in Alberta's oil sands generates oil sands process-affected
water (OSPW), which contains toxic constituents such as naphthenic acid fraction …

Selenium (Se) is an essential micronutrient that becomes toxic when exposures minimally
exceed those that are physiologically required. Studies on Se contaminated aquatic …

Selenium (Se) is an essential trace element of concern that is known to contaminate aquatic
ecosystems as a consequence of releases from anthropogenic activities. Selenium is of …

Fundamental studies characterizing transcript variability in teleost tissues are needed if
molecular endpoints are to be useful for regulatory ecotoxicology. The objectives of this …

Fathead minnow embryos and larvae are frequently used in toxicology, including short-term
embryo-only tests which often use small volumes of test solution. The effect that such …

Ecological risk assessment (ERA) of contaminated groundwater presents significant
limitations due to its often-complex chemical composition and to dynamic processes …
