Abstract :

This study was done in three mounths of summer season of year 2006 in intertidal zone in the Boshehr town in 4 transcet . Gracillaria, Padina, Acantophora, Laurencia, Digenia, Gania Gellidium, Sargassum,Cladophora, Caulerpa, Entromorpha, Halimeda were indicated in intertidal zone of Boshehr Then, were analized samples with absorb atomic machines and considered word limited for metales such as Cr, Cd and Co Result measurement of heavy metal in macro alge show that ,there is not any Co and Cr in waters intertidal zone in Boshehr, also Co in macroalge. the most of Cd measured 0.88 ppm in Padina of Brown alge in Radar site and in Caulerpa 0.47 ppm of green alge in Plaj station. the most of Cr measured in Padina 0.6 ppm of Brown alge in Student park, and 0.1 ppm in Acantophora, Laurencia, Gellidium, Graciilaria in Student park and Jalali station.
