PAH Exposure and Disease Susceptibility

Science Center Objects

Researchers at the MMFS are studying the immediate and delayed effects of petroleum hydrocarbon exposures to Pacific herring.

The immediate and delayed effects of petroleum hydrocarbon (PAH) exposures to Pacific herring are being determined empirically.  Endpoints include immediate morphological and physiological impacts on PAH-exposed embryos and larvae and delayed impacts to the surviving juveniles including changes to innate and adaptive immunity, transcriptomics, and disease susceptibility.
