This study is focused on measuring lead in environmental matrices (surface water, sediment and tissues of recreational fish species) at locations known for high levels of recreational fishing activities (i.e. locations with high uses of lead in fishing sinkers and jigs) to determine the fate and...

As part of the research program on the aquatic ecotoxicology of nanomaterials, a study was carried out using the invertebrate Hydra vulgaris in order to determine the influence that the shape of nanoparticles (sphere, cube and prism) have on the toxic potential of silver nanoparticles. The...

Substituted phenylamines (SPAs) are incorporated into a variety of consumer products (e.g., polymers, lubricants) in order to increase the lifespan of the products by acting as a primary antioxidant. Based on their physicochemical properties, if SPAs were to enter the aquatic environment, they...

The toxic effects of a representative mixture (mining activities) of rare earth elements are studied in the hydra, an organism particularly sensitive to these elements. All data are a part subject of a publication containing method details, full QA/QC, interpretation and conclusions. Citation:...

In this study, Daphnia magna transcriptomic response was measured by microarray to evaluate sublethal effects of TBOEP as part of a multi-level biological approach including specific gene transcription measured by qRT-PCR, enzyme activity, and life-history endpoints (i.e., survival, growth, and...

In this study, the chronic effects of 2 BZT-UVs, 2-(2H-benzotriazol-2-yl)-4,6-bis(1-methyl-1-phenylethyl)phenol (UV-234) and 2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol (UV-328) were evaluated for each compound alone and in a mixture on the freshwater green algae Chlamydomonas reinhardtii...

This dataset includes all ministerial condition (MC) notices published under the authority of the Canadian Environmental Protection Act, 1999 (CEPA). The MC notice may be applied to a new substance or living organisms when Environment and Climate Change Canada and Health Canada suspect that a new...
