Journal ArticleDOI
Bioaccumulation and critical body residue of PAHs in the amphipod, Diporeia spp: additional evidence to support toxicity additivity for PAH mixtures.
TL;DR: Toxicity was determined for both mortality and immobility and on both a TWA water concentration and a body residue basis and support the contention that the PAH act at the same molar concentration whether present as individual compounds or in mixture.
Reference BookDOI
Ecotoxicology of Explosives
TL;DR: In this article, the authors present a multidiscip approach for managing contaminated sites contaminated with munitions constituents, drawing on a multidisciplinary multi-modal approach for the purpose of ecotoxicological research.
Journal ArticleDOI
Toxicity of the explosives 2,4,6-trinitrotoluene, hexahydro-1,3,5-trinitro-1,3,5-triazine, and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine in sediments to Chironomus tentans and Hyalella azteca: Low-dose hormesis and high-dose mortality
TL;DR: The results of the current investigation suggest that organisms exposed to explosives at contaminated sites may be affected at concentrations less than 25 mg/kg through hormetic growth enhancement and at higher concentrations through increased mortality.
Journal ArticleDOI
Bioaccumulation of sediment-associated fluoranthene in benthic copepods: uptake, elimination and biotransformation
TL;DR: Given that fluoranthene was taken up from spiked sediment very efficiently and reached steady-state levels in the tissues very rapidly, PAH-contaminated sediments may pose a risk for benthic copepods and their predators.
Journal ArticleDOI
Toxicity of sediment-associated PAHs to an estuarine copepod: Effects on survival, feeding, reproduction and behavior
TL;DR: Although mortality only occurs at exceedingly high concentrations, PAH sublethal effects will likely reduce fitness and alter S. knabeni distribution and abundance in heavily contaminated sites.
