Abstract: Abstract：This paper has analyzed the heavy metal content in halobios and sediments of the Jiaozhou Bay. The authors first used geochemical method to analyze the enrichment characteristics of heavy metals of halobios, and then adopted the Spearman's correlation coefficient analysis method to analyze the relationship between the heavy metals in halobios and sediments. The analytical results show that fish has low ability in enriching heavy metals, whereas shellfish and algae have strong ability in this aspect. The heavy metals in sediments can also stimulate or prohibit the absorption of other heavy metals by halobios and have especially strongest inhibition function on shellfish. The results obtained by the authors can provide a basis for selective breeding and planting of halobios.
