Abstract
The ranges of background concentrations of Fe, Mn, Zn, Cu, and Cd in Fucus algae from the Sea of Japan, the Sea of Okhotsk, and the White Sea were determined. The lower background threshold of element concentration was calculated as Me15–2MAD15, the upper background threshold was determined as Me+2MAD. The upper background threshold of the metal contents in Fucus algae can be used as the maximum permissible regional concentration in assessing pollution levels of marine habitats. Comparison of the Me15–2MAD15 values showed that Fucus algae of the White Sea had increased Mn and decreased Cd concentrations compared to those in Pacific algae. The concentrations of Zn were higher in Fucus algae of the Sea of Japan than in macrophytes from the White Sea and the Sea of Okhotsk. The background concentration range of Fe in Fucus algae of the Sea of Japan was much narrower compared to that in their counterparts from the White Sea and the Sea of Okhotsk. The background metal concentrations in Fucus algae are specific to a sea region; their variations are connected not only with the trace element contents in abiotic components of the environment, but also with the functioning of coastal ecosystems.
