Figure 3. — Exposure trends over time of selected work groups for all states for benzene and ethylbenzene. WG1 = ‘All land’, WG2 = ‘Repaired oily booms’ (LA), WG3 = ‘Fueled engines’, WG4 = ‘Cleaned beaches/non-specific tasks’, WG5 = ‘Boom deploy & pickup in shallow water’, WG6 = ‘Maintained pumps/tanks or pumped (including dis/connect) anything (inc oil)/land or water (exc dispersant injection)’. Lack of a symbol for a particular TP means either that no samples were taken or the measurements did not meet the N > 5 and censoring <80% criteria.
