The aim of the study was the assessment of Cystoseira phytocenosis role as a biological barrier in cleaning of seawater in the SPNA Cape Martyan marine area against its pollution with heavy metals (HM: V, Fe, Co, Ni, Cu, Zn, Hg, Mo, Ag, Cd, Sb, Pb) and organochlorine compounds (OCC: DDT, DDE, DDD, $\Sigma$DDT, PCB 28, PCB 52, PCB 101, PCB 138, PCB 153, PCB 180). It was deduced that the significant role of Cystoseira phytocenosis in extraction of HM (from 9 to 99%) and of OCC (from 55 to 96%) from the aquatic environment is determined by its high specific biomass (up to 4.6 kg$\cdot$m⁻²) and accumulating ability against pollutants with concentration factors of n$\times$(10²$÷$10⁵) for HM and n$\times$(10²$÷$10³) for OCC. Resulting from the Cystoseira production processes, extraction of pollutants from biotope by the algae amounted to 0.1$÷$967.6 kg$\cdot$y⁻¹ for HM and 0.044$÷$8.360 g$\cdot$y⁻¹. It was shown that the most optimal way of recreational zones quality management regarding marine environment pollution factor is the maintenance of the coastal Cystoseira phytocenoses and taking of measures increasing their dispersion and production indices.

这项研究的目的是评估Cystoseira菌群病作为SPNA Martyan海角海洋区域清洁海水免受重金属（HM：V，Fe，Co，Ni，Cu，Zn，Hg， Mo，Ag，Cd，Sb，Pb）和有机氯化合物（OCC：DDT，DDE，DDD，$\Sigma$DDT，PCB 28，PCB 52，PCB 101，PCB 138，PCB 153，PCB 180）。据推断，Cystoseira phytocenosis在水生环境中提取HM（从9％到99％）和OCC（从55％到96％）中的重要作用是由其高比生物量（最多4.6 kg）决定的。$\cdot$m ^-2）和浓度因子为n的污染物累积能力$\times$（10 ²$÷$10 ⁵）对于HM和n$\times$（10 ²$÷$10 ³）用于OCC。Cystoseira生产过程的结果是，藻类从生物群落中提取的污染物总计为0.1$÷$967.6公斤$\cdot$y ^-1（对于HM和0.044）$÷$8.360克$\cdot$y ^-1。研究表明，关于海洋环境污染因素的休闲区质量管理的最佳方法是维持沿海的Cystoseira植物群落，并采取措施提高其分散度和生产指数。
