Abstract—An exploratory study on sediment and soil intertidal land, as the natural pollutant storage and purification
contamination of heavy metals was carried out along Dalian field, this zone is facing a great environmental pressure,
coastal regions in Liaoning province, China. Estuarine intertidal especially the tidal flat which is located in the both sides of
sediment samples and their adjacent upland and paddy soil estuary and coast. The intertidal land is one of the important
samples were analyzed by atomic absorption spectrophotometry destination of heavy metal due to the discharge of coastal
for Zn, Cu, Pb and Cr. The contamination of the sediments and sewage and the pollutant from the rivers into the sea [2]. The
soils was assessed on the basis of enrichment factor (EF) and concentration of heavy mental in the intertidal land can truly
