Toxic cyanobacterial blooms, their prevalence in freshwaters, and their impact on water quality are well documented. In contrast, the impact on the recreational value of bathing sites of the cyanotoxin-contaminated inland waters, transported to estuarine and coastal marine waters, has been less frequently studied. The aim of this work was to assess water quality at bathing sites located in the southern Baltic Sea and the Curonian Lagoon, using cyanotoxins concentrations as an indicator. Our results showed that higher diversity and concentrations of cyanotoxins in some areas of the coastal zone are related to the transport of waters from the Curonian Lagoon. The studied bathing sites had a relatively low probability of adverse health effects, with a potential higher risk in the southern part of the Curonian Lagoon (Lithuania). Due to the observed changes in the cyanobacteria community, the determination of cyanotoxins concentrations, irrespective of the analysis of cyanobacteria, is recommended.

是否对淡水咸咸连续水域影响的沿海沐浴水中的cHAB有担忧?

有毒的蓝藻水华,它们在淡水中的流行及其对水质的影响已得到充分证明。相比之下,被运输到河口和沿海海洋水域的,被氰毒素污染的内陆水域对沐浴场所娱乐价值的影响的研究却很少。这项工作的目的是使用氰毒素浓度作为指标,评估位于波罗的海南部和库尔斯沙嘴泻湖的沐浴场的水质。我们的研究结果表明,沿海地区某些区域中较高的多样性和浓度的蓝藻毒素与库尔斯沙嘴泻湖的水流运输有关。所研究的沐浴场所对健康造成不利影响的可能性相对较低,在库尔斯沙嘴泻湖(立陶宛)的南部,潜在的风险更高。
