The metabolism of novel flame retardants and the internal exposure and toxicity of their major metabolites in fauna - a review

Journal of Environmental Exposure Assessment, 2023
The worldwide production and usage of novel flame retardants increase their exposure to non-human fauna. Animals can accumulate and metabolize these novel flame retardants including novel halogenated flame retardants (NHFRs) and organophosphate flame ...

Risks in U.S. Bank International Exposures [PDF]

SSRN Electronic Journal, 2006
U.S. banks maintain international exposures, with Europe and the Americas as key counterparty markets. In this paper, we show the evolving scope of these exposures and the changes in the embodied risks taken through bank cross-border activity, local claims, and derivative positions. Conclusions differ across types of U.S. banks.
