In Situ Measurements of Chlorinated Hydrocarbons in the Water Column off the Palos Verdes Peninsula, California

Abstract: Spatial distributions of DDT and its primary metabolites (DDTs) and polychlorinated biphenyls (PCBs) in the water column off the Palos Verdes Peninsula, CA, were measured in the winter and summer of 1997 using an in situ sampling method. The concentrations of DDTs ranged from 0.6 to 15.8 ng/L, while those of PCBs ranged from 0.06 to 1.14 ng/L at eight sampling stations. The spatial distribution patterns of DDTs and PCBs as well as the DDT/ PCB concentration ratio in the water column were similar to those found… Show more

“…The concentrations (35.5e476.9 ng/L) of PCBs (List S2) in coastal waters of the eight islands along China's coastline (Fig. S2) (Luo et al, 2010) were two orders of magnitude higher than those in Baltic Sea (Sapota, 2004) and the coastal ocean off southern California, USA (Zeng et al, 1999), even though fewer PCB congeners were measured in the Chinese studies (Table S3). …”

“…The procedures for eluting dissolved organics from XAD resins have been described extensively by Zeng et al (1999); thus, only a brief description is given here. Each XAD resin column was spiked with surrogate standards, and eluted with 50 mL of methanol, followed by 50 mL of DCM at a flow rate of 5 mL/min.…”

“…The K oc values can be calculated from the octanol-water partition coefficients (K ow ) by using an empirical equation (Schwarzenbach and Westall 1981) as follows: log K oc =0.72log K ow +0.49. The ratio of C w,e /C w has been used to measure the tendency of SVOCs to partition into the water phase from the sediment (Zeng et al 1999) as follows:…”
