HAB occurrence is becoming more frequent and problematic in marine recreational waters. However, the exploitation of the coastal area for recreational use is promoting the necessary conditions for the HAB increase. In terms of the harmful effects, we can consider two types of causative organism: the toxic producers and the high-biomass producers. Toxic events can be produced by a very low concentration of the causative organism. This characteristic implies a difficulty for the monitoring programs in relation to human health. It is important to point out in the context of human health and HAB events, that in some coastal regions (e.g. the Mediterranean basin) HABs are an emerging problem. In these regions, the local population and visitors may face a health risk that is difficult to measure. The monitoring of toxic species has mainly been associated -with shellfish farming. However, the risk of intoxication could become even greater in areas not subject to legislation of aquaculture activities.
有害藻华（HAB）在海洋休闲水域的发生越来越频繁且问题严重。然而，沿海地区用于休闲用途的开发正在为有害藻华的增加创造必要条件。就有害影响而言，我们可以考虑两种致病生物：有毒生产者和高生物量生产者。极低浓度的致病生物就能引发毒性事件。这一特性给与人类健康相关的监测项目带来了困难。在人类健康和有害藻华事件的背景下，必须指出，在一些沿海地区（如地中海盆地），有害藻华是一个新出现的问题。在这些地区，当地居民和游客可能面临难以衡量的健康风险。对有毒物种的监测主要与贝类养殖相关。然而，在未受水产养殖活动立法管制的地区，中毒风险可能会更高。
