Abstract
|
The northern parts of the Persian Gulf are more affected by pollutants because of their low depth, limited rotation,
salinity, and high temperature. The anthropogenic and non-anthropogenic contaminations caused by organic and inorganic
pollutants in aquatic ecosystems will eventually lead to increase pollution in water, sediments, and aquatic organisms. It
seems that, algae are the most suitable indicator for soluble heavy metals (HMs) in both active and passive states. Samplings
were carried out on a monthly basis in four different stations in Bushehr Province, northwest of the Persian Gulf from March
2016 to March 2017. ICP-mass spectrometry was used to determine Pb, Cu, Cd, As, Cr, Zn, Al, Mn, Co, V, Ni, Mg, S,
Fe, and Ca concentrations in some macroalgae. In this study Padina gymnospora (brown algae) and Hypnea hamulosa
(red algae) had the highest absorption, while the Cladophoropsis membranacea (green algae) showed the least absorption in
all the sampling areas.
