Trace metals and mineral contents of some green algal seaweeds from Vadakadu (Rameswaram) coastal regions, Tamil Nadu, India

Abstract

The present study focused on the trace metal and mineral composition analysis of fiver green algal seaweeds such as Caulerpa racemosa, Caulerpa sertularioides, Ulva reticulate, Ulva lactuca and Codium tomentosum were collected from Vadakadu (Rameswaram) coastal regions, Tamilnadu, India. Among this group of seaweeds, Caulerpa sertularioides showed the maximum contents of mineral elements such as chromium, copper, and magnesium and Ulva lactuca observed the minimum level of mineral content such as cobalt, iron, magnesium, manganese, nickel, lead and zinc.
