| comparative toxicity of two chemical dispersants and dispersed oil in estuarine organisms. | chemical dispersants can be a useful tool to mitigate oil spills. this study examined potential risks to sensitive estuarine species by comparing the toxicity of two dispersants (corexit®ec9500a and finasol®osr 52) individually and in chemically enhanced water-accommodated fractions (cewafs) of louisiana sweet crude oil. acute toxicity thresholds and sublethal biomarker responses were determined in seven species (sheepshead minnow, grass shrimp, mysid, amphipod, polychaete, hard clam, mud snail) ... | 2018 | 28687868 |
| spatially explicit assessment of estuarine fish after deepwater horizon oil spill: trade-off in complexity and parsimony. | evaluating long-term contaminant effects on wildlife populations depends on spatial information about habitat quality, heterogeneity in contaminant exposure, and sensitivities and distributions of species integrated into a systems modeling approach. rarely is this information readily available, making it difficult to determine the applicability of realistic models to quantify population-level risks. to evaluate the trade-offs between data demands and increased specificity of spatially explicit m ... | 2016 | 27755711 |
| effects of louisiana crude oil on the sheepshead minnow (cyprinodon variegatus) during a life-cycle exposure to laboratory oiled sediment. | determining the long-term effects of crude oil exposure is critical for ascertaining population-level ecological risks of spill events. a 19-week complete life-cycle experiment was conducted with the estuarine sheepshead minnow (cyprinodon variegatus) exposed to reference (uncontaminated) sediment spiked with laboratory weathered south louisiana crude (slc) oil at five concentrations as well as one unspiked sediment control and one seawater (no sediment) control. newly hatched larvae were expose ... | 2016 | 26129909 |
