The concentrations of heavy metals (Cd, Cu, Ni, Pb, Zn and Mn) and macroelements (K, Na, Ca and Mg) were determined in green alga Enteromorpha sp. from the coastal zone of the southern Baltic including Gulf of Gdańsk and Vistula Lagoon in 2000-2003. In order to estimate the degree of accumulation of each element by the green alga, concentration and discrimination factors (CFs) with respect to seawater were calculated. The results of factor analysis (FA) and ANOVA clearly indicate geographical differences between concentrations of chemical elements. Enteromorpha sp. from Vistula Lagoon and the southern Baltic exhibited higher levels of Mn and Ni, and Na and K, respectively. Anthropogenic impact of Cu, Pb and Zn, possibly originated from municipal sewage, was identified in alga samples collected in the Gulf of Gdańsk, especially in the vicinity of Gdynia. From comparison our data with those published earlier results that Pb content in Enteromorpha sp. from the Gulf of Gdańsk decreased within 1978-2003 reflecting reducing use of leaded petrol in Baltic countries in this period. The alga Enteromorpha sp. can be used for biomonitoring surveys of metal contaminants in coastal areas of the Baltic Sea.
2000年至2003年期间，对来自波罗的海南部沿海地区（包括格但斯克湾和维斯瓦河泻湖）的绿藻浒苔属中的重金属（镉、铜、镍、铅、锌和锰）以及常量元素（钾、钠、钙和镁）的浓度进行了测定。为了估算绿藻对每种元素的积累程度，计算了相对于海水的浓度和区分因子（CFs）。因子分析（FA）和方差分析（ANOVA）的结果清楚地表明了化学元素浓度的地理差异。来自维斯瓦河泻湖和波罗的海南部的浒苔属分别表现出较高水平的锰和镍，以及钠和钾。在格但斯克湾采集的藻类样本中，尤其是在格丁尼亚附近，发现了可能源自城市污水的铜、铅和锌的人为影响。通过将我们的数据与早期发表的数据进行比较，结果表明，1978年至2003年期间，格但斯克湾浒苔属中的铅含量下降，这反映了该时期波罗的海国家含铅汽油使用量的减少。浒苔属绿藻可用于波罗的海沿海地区金属污染物的生物监测调查。
