这张幻灯片概述了加利福尼亚州卡尔斯巴德和亨廷顿海滩自然产生的毒素和海水淡化设施的信息。主题包括:评估赤潮/毒素的相对发生率和概率（特定地点）；评估对单个和整个单元过程的潜在影响/命运；并且，考虑实时观察毒素的存在的必要性。

This slide presentation outlines information on naturally occurring toxins and seawater desalination facilities in Carlsbad and Huntington Beach, California. Topics covered include: evaluate relative occurrence and probability of red tide/toxin (site-specific); evaluate potential impact/fate on individual and whole unit processes; and, consider the necessity to observe presence of toxins real-time.
