Abstract
Pollution from chemical and industrial wastes has far-reaching effects on ecosystems. Harmful substances such as heavy metals, persistent organic pollutants (e.g., polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs)), acid and alkali waste streams and other harmful substances enter the coastal and marine environments through rivers, sewage pipelines and other pathways, posing a serious threat to marine ecosystems and human health. Not only do these pollutants tend to accumulate in sediments, but they are also gradually amplified through the food chain, eventually reaching high concentrations in top predators and leading to biomagnification effects. In addition, ocean acidification and discharge of highly alkaline waste streams further affect carbonate-dependent marine organisms and disrupt the marine ecological balance. Understanding the environmental behavior of these pollutants and their ecological impacts is essential for developing effective pollution control and ecological protection measures.
