TRACE TOXIC MINERAL LEVELS OF SEA LETTUCE (Ulva spp.) FROM_x000D_ COAST OF ISTANBUL

Abstract

Concentrations of Nickel (Ni), Copper (Cu), Zinc (Zn), Iron (Fe), Arsenic (As), Mercury (Hg),Lead (Pb) and Cadmium (Cd) were determined in the macro algae sea lettuce (Ulva spp.), sampledfrom the coastline of Istanbul old city (Cankurtaran) in summer 2016. The abundance of trace toxicmineral concentrations in sea lettuce were in the following order: Fe > Zn > As > Cu> Ni >Pb>Cd. However, mercury was not detected in any sample. The present study provides a new information to the consumer on the distribution of trace toxic minerals in sea lettuce.
