Presence of the paralytic shellfish toxins (PSTs) saxitoxin, neosaxitoxin, decarbamoyl saxitoxin and gonyautoxin-5 was analyzed by mass spectrometry in 41 Spanish freshwaters and 13 strains of potential PST-producing planktonic cyanobacteria. Toxins were detected in five waterbodies, but were absent from the isolated strains. PST containing samples belonged to the same geographical region (South Western Spain) and were most likely related to the presence of the genus Aphanizomenon.
采用质谱法分析了 41 种西班牙淡水和 13 株潜在产生麻痹性贝类毒素（PSTs）的浮游性蓝藻中的 PSTs，包括石房蛤毒素、新石房蛤毒素、去甲氨甲酰石房蛤毒素和 GTX-5。在 5 个水体中检测到了 PST，但在分离株中未检测到。含有 PST 的样本来自同一地理区域（西班牙西南部），很可能与节旋藻属的存在有关。
