In a new study, researchers from UC San Diego’s Scripps Institution of Oceanography and San Diego State University found that deep-sea fish and sediments collected near the Catalina Island offshore dump site are contaminated with numerous DDT-related chemicals. The study, recently published in the journaland funded by the National Oceanic and Atmospheric Administration, reveals that the remnants of DDT dumped decades ago may continue to infiltrate the marine food webs.
“Regardless of the source, this is evidence that DDT compounds are making their way into the deep ocean food web,” said Margaret Stack, an environmental chemist at SDSU and the study’s lead author. “That is cause for concern because it’s not a big leap for it to end up in marine mammals or even humans.”
Numerous additional studies are ongoing to answer these urgent questions. Researchers at Scripps and SDSU are currently analyzing samples from fish species targeted by recreational anglers and commercial fisheries, including basses and sanddab, for DDT+. Comparing the chemicals and their concentrations found in these fish with sediment samples collected from the Palos Verdes Shelf and Dumpsite 2 may allow the team to determine the source of the toxins in these fish.
