Blooms of blue-green algae from 51 eutrophic Scandinavian lakes were investigated during the period 1978–1984, to ascertain the occurrence of toxinogenic species. Toxicity assays were performed by intraperitoneal injection of suspensions of freeze-dried algal material in mice. Toxin-producing blue-green algae were found in 30 lakes. They belonged to 11 different species of the six genera Anabaena, Aphanizomenon, Gomphosphaeria, Microcystis, Nodularia and Oscillatoria. The presence of toxinogenic strains of blue-green algae seemed quite constant in several of the localities studied. In some lakes, more than one toxic species were found to develop simultaneously. The level of toxicity showed large variation (MLD, 6 to > 2500 mg/kg), but clinical and pathological changes were quite uniform. The results indicate that water-blooms of toxin-producing blue-green algae, in the geographical area in question, are regionally widespread. In some localities, blooms of blue-green algae are apparently always toxic. Several aspects of the toxic blue-green algae problem are discussed.
1978年至1984年期间，对来自51个富营养化的斯堪的纳维亚湖泊的蓝藻水华进行了调查，以确定产毒物种的存在情况。通过向小鼠腹腔注射冻干藻类材料的悬浮液进行毒性测定。在30个湖泊中发现了产毒蓝藻。它们属于鱼腥藻属、束丝藻属、胶磷藻属、微囊藻属、节球藻属和颤藻属这六个属中的11个不同物种。在所研究的几个地点，产毒蓝藻菌株的存在似乎相当稳定。在一些湖泊中，发现不止一种有毒物种同时出现。毒性水平差异很大（最小致死剂量，6至>2500毫克/千克），但临床和病理变化相当一致。结果表明，在所讨论的地理区域内，产毒蓝藻的水华在区域上广泛分布。在一些地方，蓝藻水华显然总是有毒的。文中讨论了有毒蓝藻问题的几个方面。
