Fish liver tissue measurements of aryl hydrocarbon hydrolase (AHH) activity, an indicator of contaminant exposure, collected from U.S. coastal and estuarine sites. The data was produced by NOAA's National Benthic Surveillance Project as part of the National Status and Trends program. Sampling occurred between 1988 and 1992.
Use Cases
- Analyze trends in AHH activity levels across different U.S. coastal sites to identify pollution hotspots.
- Correlate AHH measurements with recorded incidences of visible lesions or histopathological conditions in fish tissues.
- Model the relationship between AHH induction and concentrations of organic or inorganic contaminants in sediment or fish liver.
- Assess long-term changes in coastal environmental quality by comparing AHH data with other bioeffects measurements over time.
Strengths
- Data collection is part of a long-term national monitoring program initiated in 1984.
- Covers a defined 5-year time period from 1988 to 1992.
Limitations
- Data is over 30 years old, limiting analysis of current coastal conditions.
- Specific sample size (row count), geographic sites, and column details are unknown.
