测定了保加利亚黑海沿岸6种绿色大型藻类的铁、锰、铜、铅、镉的含量分布。在1996年至2002年的六个季节中，使用原子吸收光谱仪(AAS)对这些金属进行了测量。样本从八个不同的地点收集--Shabla、Kaliakra、Tuzlata、Ravda、Ahtopol和Sinemoretz。获得的所有藻类的重金属(HM)数据(平均值μg/g)分别为：Fe 6 5 0±10 0，Mn184±15，Cu5.6±0.5，Pb3.3±0.3，Cd 1.1±0.2。HM含量的测定结果表明，不同物种对重金属的积累程度不同，研究区北部较高的HM含量可归因于大河流进入黑海-多瑙河、第聂伯河、第聂斯特河和当地污染物排放的影响。所有数据显示，整个保加利亚黑海沿岸没有发现含有重金属和有毒金属的绿色巨藻受到严重污染。
Fe, Mn, Cu, Pb and Cd concentration distribution in six green macroalgae species from the Bulgarian Black Sea coast were determined. The measurement of these metals was carried out during six seasons from 1996 to 2002 using atomic absorption spectrometry (AAS). Samples were collected from eight different sites–Shabla, Kaliakra, Tuzlata, Ravda, Ahtopol and Sinemoretz. The obtained heavy metal (HM) data (mean values μ g/g) for all algae are: 650 ± 100 for Fe, 184 ± 15 for Mn, 5.6 ± 0.5 for Cu, 3.3 ± 0.3 for Pb and 1.1 ± 0.2 for Cd. The obtained HM contents indicate that different species demonstrate various degree of metal accumulation and the obtained higher values in the northern sector of the studied zone can be attributed to the discharge influence of the big rivers, entering the Black Sea–Danube, Dnyepr, Dnester and local pollutant emissions. All data show that there is no serious contamination in green macroalgae with heavy and toxic metals along the whole Bulgarian Black Sea coast.
