摘要：This study is a contribution to the assessment of water quality of the Algiers Bay in terms of chemical pollution. Metallic trace elements (Mercury, Lead and Zinc) were identified using the atomic absorption spectrophotometry on samples taken in the Posidonia ecosystem (sediment, Posidonia oceanica and Paracentrotus lividus). Samples come from two stations located in the extreme East and West of the Algiers Bay (Algiers beach and Rais Hamidou). Results of atomic absorption spectrophotometry showed that the site Rais Hamidou is most contaminated by the MTE website Algiers beach. In addition, the zinc is the most bioaccumulated in three MTE studied, and species (P. lividus) is the most bioaccumulatrice of the three compartments of the ecosystem studied
