Petroleum Hydrocarbons in Fish

Collected fish from Teshekpuk, Ikpikpuk, Colville/Nuiqsut fishery areas; sampled fish and sediments for baseline PAHs (focused on broad whitefish and burbot). This project analyzes PAHs and biomarkers. No direct testing of other contaminants was done. Biomarker results give some indication of general health status/exposures of fish.

To date we have:

Fish and sediment results from Teshekpuk Lake, Mayurgiaq, Ikpikpuk, Colville River areas (broad whitefish, burbot, and sediments or bottom mud). Samples of fish from Wainwright & Atqasuk subsistence fishing sites. Analyses in progress. So far, as expected and overall, the fish tissue levels of PAH contamination have been very low or non-detectable. PAHs were detected in all sediments (not surprisingly, low levels) and showed several different profiles (component varieties) suggesting different or a combination of sources of petroleum. Some fish liver samples were analyzed for biomarkers (specific measures of chemical changes related to stressors, exposures to contaminants, and the health condition of the fish) – no biomarker sign that fish are stressed, and the final report is pending.
