Photos from a UC Davis / NOAA study show the effects of phototoxicity in Pacific herring embryos. Embryos on the left are unexposed to oil; those on the right have been in oil and then exposed to sunlight and show cells destroyed.
Bad news for the Gulf of Mexico: a study released this week sheds new light on the toxicity of oil in aquatic environments, and shows that environmental impact studies currently in use may be inadequate. The report is to be published this week in the Proceedings of the National Academy of Sciences.
The study, spearheaded by the UC Davis Bodega Marine Laboratory in collaboration with NOAA, looked into the aftermath of the 2007 Cusco Busan spill, when that tanker hit the San Francisco-Oakland Bay Bridge and spilled 54,000 gallons of bunker fuel into the bay.
The key finding involved the embryos of Pacific herring that spawn in the bay. The fish embryos absorbed the oil and then, when exposed to UV rays in sunlight, physically disintegrated. This is called phototoxicity, and has not previously been taken into account when talking about oil spills.
