Tracing sewage pollution using linear alkylbenzenes (LABs) in surface sediments at the south end of the Southern California Bight

Distribution and isomeric composition of LABs in surface marine sediments were evaluated at the southern end of the southern California Bight. LABs are used as tracers of wastewater discharges. The area studied extends from the Mexico-USA border to the Todos Santos Bay, Baja California in the south....

Description
Summary:Distribution and isomeric composition of LABs in surface marine sediments were evaluated at the southern end of the southern California Bight. LABs are used as tracers of wastewater discharges. The area studied extends from the Mexico-USA border to the Todos Santos Bay, Baja California in the south. The area was partitioned into a northern, central and a southern stratum. GC-MS was used for the analysis of LABs concentration. The average value of total LABs concentration was 17.4, 32.0 and 24.9 ng/g for the north, central and southern strata, respectively. LABs were not correlated with either sediments grain size (%
