Terrestrial Pollution

Land pollution is deposited and accumulated in estuary and coastal areas by attaching to particles suspended in rivers. Therefore, pollution status and its history can be understood by analyzing and monitoring sediments in estuaries and lagoon areas. Sediment not only acts as a pollution carrier, but also as a potential source of secondary pollution in the water system. High PAH concentrations in sediments are usually high in industrial and urban locations. In addition, highly anthropogenic activities are generally recognized as the most important source of release of PAHs into the environment. Soil contamination or soil pollution as part of soil degradation is caused by the presence of xenobiotic chemicals or other changes in the natural soil environment. This is usually caused by industrial activities, agricultural chemicals or improper disposal of waste. Ecosystems and Air Quality. Research shows that air pollution can affect ecosystems.
