Table 7: Hydrocarbon distributions in Ben Schoeman Dock Basin surficial sediments in 2005 (modified from CSIR 2005). Screening and maximum level thresholds are from DEA&T (1998) and BCLME (2004). The sample locations are shown on Figure 7, the LF samples were taken from outside of the harbour and indicate local background concentrations.
