Context: Compound and species selection
In this section hydrocarbons will be selected to be included in the exposure assessment (1). Next, aquatic organisms will be enabled from the pre-defined list of generic animal groups (2). Finally, two scenarios are to be created, to reflect properties of the bulk oil. It will drive the initial conditions of the spilled oil, such that Scenario 1 will represent fresh crude oil, and Scenario 2 weathered oil, which can be defined as oil that lost some of its mass due processes such as evaporation (3). The assumption here is that physico-chemical properties of the weathered crude oil differ from the fresh oil due to evaporative mass loss, 0% and 19.4% in case of fresh and weathered crude oil respectively. This will affect fate and subsequent bioaccumulation level of the selected petroleum hydrocarbons.
