The study measured heavy metal levels in coastal sediments of northern Dongying City. They found higher concentrations near the Tiaohe River mouth due to natural and human sources. Some metals exceeded safe levels, posing risks to marine life. Cd and Hg were the main contributors to ecological risk. Controlling metal pollution from rivers is crucial to reduce harm.
