This used estimates of the actual oil spilled [ 3436 ] and the assumed droplet size distribution at the time of the release [ 37 ]. Vertebrates and some exploited invertebrates are tracked by numbers and body weight, while non-exploited invertebrates are handled as biomass pools.
This serves as a proxy for how intimately a functional group associates with contaminated sediments. Abstract Background The purpose of this study was to assess the long-term adverse health effects of the Deepwater Horizon Gulf oil spill exposure in workers who participated in its cleanup work.
Unfortunately, we did not have enough sediment oil data from the field to use directly as the oil driver in the simulations.

Organisms used in lab and field exposure studies to develop the dose-response models were typically from chronically oil-exposed areas [ 25 ]. Notably, at their 7-year follow-up visit, most of the oil spill exposed subjects had also developed chronic rhinosinusitis and reactive airway dysfunction syndrome as new symptoms that were not reported during their initial visit.
However, Atlantis polygons are more than 25, km2 on average and include areas of both below- and above-average deposition rates, thus small-scale spatial variations can be ignored.
