Pyrethroid concentrations and persistence following indoor application

Residential indoor environments are potential sources of exposure to pyrethroids, which have low acute toxicity to humans but are allergenic and suspected endocrine disruptors. Nakagawa et al. evaluated the persistence of the pyrethroids cypermethrin and beta-cyfluthrin on indoor surfaces and in house.... more

Rapid depuration of mercury in songbirds accelerated by feather molt

Mercury (Hg) is a ubiquitous environmental contaminant that affects avian reproduction and condition, in both aquatic and terrestrial species. Because Hg binds strongly to the keratin of growing feathers, molt is an important avenue for Hg elimination. A study published in Environmental Toxicology and.... more

Estimation of vanadium water quality benchmarks for the protection of aquatic life with relevance to the Athabasca Oil Sands region using species sensitivity distributions

Elevated vanadium (V) concentrations in oil sands coke, which is produced and stored on the site of some major Athabasca Oil Sands companies, could pose a risk to aquatic ecosystems in northern Alberta, Canada, depending on its future storage and utilization; until very recently, there were no established.... more
