The contents of Cd, Cu, Ni, Pb, Zn, Mn, K, Na, Ca and Mg were determined in the green algae Cladophora sp. from coastal and lagoonal waters of the southern Baltic. Factor analysis demonstrated spatial differences between concentration of chemical elements. The algae from the southern Baltic contained more Na and K while the anthropogenic impact of Cu, Pb and Zn was observed in the case of Cladophora sp. and Enteromorpha sp. from the Gulf of Gdansk at the vicinity of Gdynia. This area is exposed to emission of heavy metals from municipal and industrial sources with the main contribution of shipbuilding industry and seaport. The statistical evaluation of data has demonstrated that there exists a correlation between concentrations of Cu, Pb and Zn in both green algae collected at the same time and sampling sites of the Gulf of Gdansk. Our results show that in the case of absence of one species in the investigated area it is still possible to continue successfully the biomonitoring studies with its replacing by second one, i.e. Cladophora sp. by Enteromorpha sp. and vice versa; in consequence reliable results may be obtained.
测定了来自波罗的海南部沿海和泻湖水域的绿藻刚毛藻中镉、铜、镍、铅、锌、锰、钾、钠、钙和镁的含量。因子分析表明化学元素浓度存在空间差异。波罗的海南部的藻类含有更多的钠和钾，而在格但斯克湾格丁尼亚附近的刚毛藻和浒苔中观察到了铜、铅和锌的人为影响。该地区受到来自市政和工业源的重金属排放影响，主要来自造船业和海港。数据的统计评估表明，在格但斯克湾同时采集的两种绿藻中，铜、铅和锌的浓度与采样地点之间存在相关性。我们的结果表明，在所研究区域如果缺少一种物种，仍然可以通过用另一种物种替代它来成功继续生物监测研究，即用浒苔替代刚毛藻，反之亦然；因此可以获得可靠的结果。
