High concentrations of toxic heavy metals in estuaries are most likely to be found in

Quizplus · Accepted Answer

Toxic heavy metals such as lead, mercury, cadmium, and arsenic tend to bind to sediments in estuaries and accumulate over time. This makes sediments the most likely place to find high concentrations of these pollutants. While heavy metals may also be present in the water, their concentrations are typically lower due to dilution and can vary depending on tides and currents. The air above the estuary and adjacent land is not a significant pathway for heavy metal accumulation. The water of the adjacent ocean can also contain heavy metals, but their concentrations are usually lower than in estuarine sediments.
