Domoic Acid Workshop
On May 4, 2017, OEHHA and UC Davis co-hosted a domoic acid workshop at the UC Davis Buehler Alumni Center to discuss the state of the science and implications for human toxicity. Representatives from academia, government, and non-profit organizations participated in scientific lectures, panel discussions, and audience question and answer sessions on topics related to the potential health impacts of domoic acid exposure.
Discussion topics included:
- Effects reported in marine mammals and rodents, and their relevance to human health
- Chronic, low-level domoic acid exposure in humans
- Pharmacokinetics and understanding the human dose
- Endpoints relevant to Autism Spectrum Disorders
