West Florida Shelf beach sediment PAH and dioctyl sodium sulfosuccinate concentrations, microtox luminescence and microscreen mutagenicity data, 2010 to 2013

Six cohesive sand patty sediments were collected on a West Florida Shelf beach in St. Petersburg Florida, January, 2013. These were analyzed for presence of PAH compounds and the composition compared to measurements from known Deepwater Horizon contaminated beach sediments. Known contaminated samples were collected from Santa Rosa Florida in July 2010 and January 2011, and from Gulf Shores Alabama in December 2012. The same samples were also analyzed for biological activity and the presence of Corexit dispersant (DOSS). This dataset includes concentration data for PAHs and DOSS in these samples. The biological activity in the water accommodated fraction of samples was measured through Microtox toxicity and Microscreen mutagenicity. The data provided for these analyses includes luminescence, and percent change and inhibition compared to controls. DOSS concentration analysis, microtox and microscreen assay data for control sand, loose beach sand collected in proximity to sand patty samples, is also provided in this dataset. Phenol controls were employed in Microtox analysis, and luminescence data is provided for controls.
