Figure 2. — Exposure trends over time of selected work groups for all states for toluene and xylene. WG1 = ‘All land’, WG2 = ‘IH/safety = land’, WG3 = ‘Clean beaches/non-specific tasks’, WG4 = ‘Boom deploy & pickup in shallow water’, WG5 = ‘Removed tar balls and oil/beaches & marshes’, WG6 = ‘Removed oil using hand equipment and/or searched under sand & water’. 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.
