Impact/Purpose:
The present study provides a baseline for assessing whether dredging the Passaic River will significantly impact bioavailable PCDD/PCDFs in Newark Bay and the magnitude of release to the air. The results suggest freely dissolved PCDD/PCDFs enter Newark Bay by way of several distinct pathways. Most freely dissolved PCDD/PCDFs in the bay do not come from the Passaic only, but rather from other incoming waters as well (such as 2,4,8-TriCDF and 2,3,7,8-TCDF from the Elizabeth River), possibly due to release from sediments to the dissolved phase and subsequent delivery into the bay. An exception was 2,7/2,8-DiCDD, which likely originated from triclosan released from the PVSC near the eastern entry to the Kill van Kull. A separate case was 2,3,7,8-TCDD, which displayed significant inverse correlations to two freshwater proxies at the Passaic River only. The information in this article will be useful for scientists and managers involved with assessing the risks associated with remedial dredging of toxic chemicals (e.g., dioxins, furans) in large urbanized systems such as The New York/New Jersey Harbor Estuary.
