INFLUENCING FACTORS OF HEAVY METALS IN THE COASTAL AREAS

This study investigates the distribution and influencing factors of six heavy metals (Cr, Zn, Ni, Cu, Pb, Cd) in water and sediments from the coastal areas of the Yangtze River estuary. Field surveys at seven sites revealed that heavy metal concentrations are significantly affected by physicochemical parameters such as temperature, pH, redox potential, salinity, and conductivity. Strong correlations among Cu, Cr, and Ni suggest common sources or pathways. The findings provide insights into heavy metal behavior in estuarine environments and offer technical support for pollution control and water quality management
