Abstract
Nearshore artificial reefs and fishes relying on them to forage and refuge can be susceptible to trace element (TE) pollutants from anthropogenic sources. Although some TE are essential, higher concentrations can cause detrimental effects and concern regarding consumption. This study assesses TE accumulation in nearshore reef fishes in the northern Gulf of Mexico, a region influenced by coastal riverine discharge, where fishing has socioeconomic importance. Five fish species from six eco-reefs were collected and analyzed for TE. An inductively coupled plasma mass spectrometer was used to analyze the TE concentrations of muscle, liver, and otoliths. TE concentrations of tissues and otoliths were additionally compared to the environment. High variation in TE concentration was observed across species, seasons, and tissues. Findings indicate TE concentration profiles were influenced by fish reliance on the reef, exposure, age, and movement pattern. Some muscle tissue was found unsafe for consumption.
