A literature review of bioaccumulation and biotransformation of organic chemicals in birds was undertaken, aiming to support scoping and prioritization of future research. The objectives were to characterize available bioaccumulation/ biotransformation data, identify knowledge gaps, determine how extant data can be used, and explore the strategy and steps forward. An intermediate approach balanced between expediency and rigor was taken given the vastness of the literature. Following a critical review of >500 peer-reviewed studies, >25,000 data entries and 2 million information bytes were compiled on >700 organic compounds for ~ 320 wild species and 60 domestic breeds of birds. These data …

The U.S. Department of the Interior recently included uranium (U) on a list of mineral commodities that are considered critical to economic and national security. The uses of U for commercial and residential energy production, defense applications, medical device technologies, and energy generation for space vehicles and satellites are known, but the environmental impacts of uranium extraction are not always well quantified. We conducted a screening-level ecological risk analysis based on exposure to miningrelated elements via diets and incidental soil ingestion for terrestrial biota to provide context to chemical characterization and exposures at breccia pipe U mines in northern Arizona. …
Risks And Hazards Of Rodenticide To Non-Raptor Birds, Nimish B. Vyas
Risks And Hazards Of Rodenticide To Non-Raptor Birds, Nimish B. Vyas

Incident data can support risk assessments by providing evidence of adverse effects of rodenticides to birds following operational applications. Traditionally, field monitoring for rodenticide incidents has focused primarily on raptors. However, nonraptor birds may also be poisoned (rodenticide exposure resulting in adverse effects including mortality) by rodenticides through consumption of the rodenticide bait and contaminated prey. I conducted a literature search canvassing 12 government and scholarly databases for rodenticide incidents (evidence of exposure to a rodenticide, adverse effects, or exposure to placebo baits) involving non-raptor birds. I used the search terms ‘rodenticide’ and ‘birds’ and from these results, I excluded …

Despite widespread use and benefit, there are
growing concerns regarding hazards of second-generation
anticoagulant rodenticides to non-target wildlife which
may result in expanded use of first-generation compounds,
including chlorophacinone (CPN). The toxicity of CPN
over a 7-day exposure period was investigated in American
kestrels (Falco sparverius) fed either rat tissue mechanically-
amended with CPN, tissue from rats fed Rozol bait
(biologically-incorporated CPN), or control diets (tissue
from untreated rats or commercial bird of prey diet)
ad libitum. Nominal CPN concentrations in the formulated
diets were 0.15, 0.75 and 1.5 µg/g food wet weight, and
measured concentrations averaged 94 …
