Figure 1. — Inhalation exposure estimates for total hydrocarbons (THC), benzene, ethylbenzene, toluene, xylene and n-hexane (BTEX-H) by time period (THC = ppm; BTEX-H = ppb) for ‘All rig vessels’, ‘All ROVs’, ‘All fire control vessels’, ‘All research vessels’, ‘All Other Water Operations’, and ‘All Land Operations’. ROV vessels: vessels that piloted remotely operated vehicles (ROVs). The benzene graph showing the higher AMs for ‘All Other Water Operations’ is due to an artifact of the methods used by the labs to calculate the limits of detection.
