科学家发现，受尿素污染的海藻能生成一种致密毒素软骨藻酸。
Urea pollution can trigger ocean algae to produce a deadly toxin called domoic acid, scientists have discovered.
软骨藻酸还可能造成吃了这些中毒鱼类的动物神经紊乱和死亡。
Domoic acid can also cause neurological disorders and death in animals that eat fish poisoned with the neurotoxin.
结果表明，HPLC方法是检测水及水生动物中软骨藻酸的简便有效方法。
The result showed that HPLC analysis was a simple and effective method for determining domoic acid in water and aquatic animals.
拟菱形藻能够释放软骨藻酸，这个本领确实可怕。它所释放的软骨藻酸附在铁上，能够被藻类再吸收。
Pseudonitzschia appears to benefit from its ability to produce domoic acid, which binds with iron and can then be reabsorbed by the algae.
戴维·卡隆教授表示，对3月8日鱼类死亡事件当天采集到的死鱼检测显示，死鱼胃中残留物呈软骨藻酸“强阳性”。
Professor David Caron said fish collected on March eighth, the day of the kill, tested "strongly positive" for domoic acid in their stomach contents.
南加州大学的研究人员证实，第二天在雷东多比奇西南方20公里处收集的浮游生物中含有很高的软骨藻酸。
Researchers from USC confirmed that plankton collected about twenty kilometers southwest of Redondo Beach the next day had very high levels of domoic acid.
引起人们忧虑的藻类学名叫伪菱形藻(pseudo-nitschia)，这种藻类能够产生一种名为软骨藻酸的毒物。
The algae of concern is pseudo-nitschia, which produces a toxin called domoic acid.
采用含甲醇的水溶液，选择性地提取鲜淡菜中软骨藻酸，经离心、过滤等手段进行样品处理，在最优化的条件下进行液相色谱检测。
The method includes the selective extraction of domoic acid in fresh mussel, the pretreatment with centrifuge and filter, chromatographic analysis in the optimized conditions.
有害藻类的大量繁殖是导致鱼类死亡的常见原因。如果一些动物食用了神经毒素中毒的鱼类，软骨藻酸也会导致这些动物神经系统紊乱甚至死亡。
Harmful algae blooms are a common cause of fish kills. Domoic acid can also cause neurological disorders and death in animals that eat fish poisoned with the neurotoxin.
