Apart from key ecological role, some algal species have emerged as important indicators of chemical pollutants. Among such algal species, Cladophora glomerata L. which is a prevalent filamentous green alga found along the southern coast of Caspian Sea has emerged as important indicator of some metal pollution. The current study reports the analysis of Cladophora samples during summer of 2016 for selected metals and other nutrients. The antioxidant activity was also investigated in collected algal samples from various sampling points along the Caspian Sea with peak tourists’ activity. The detection of heavy metals in Cladophora glomerata was found higher than normal background levels for studied metals (Cu, Zn, Mn and Fe). Such higher values of metals in this indicator species is alarming and shows a threat to recreational value of Coasts of Farah Abad region along Caspian Sea. It is urged that policy makers and stakeholders need to devise strategies to protect coastal areas of Caspian Sea so retain their recreational value and natural ecological phenomenon.
