Phytoplankton form the base of the marine food chain. Most phytoplankton are benign and indeed positively benefitial to the health of the environment. However, a minority of phytoplantkon are harmful to humans, the environment or the economy as a result of their prouction of toxic substances. These phytoplankton are often called harmful algal blooms or HABs. Toxic phytoplankton may be ingested by filter feeding shellfish that are not themselves harmed but which accumulate and concentrate the toxin in their tissue. If the shellfish are them eaten by humans potentially serious illness may occur. Monitoring programs of phytoplankton and shellfish flesh act as a means of minimising the heath risk to humans of shellfish consumption. Hwever, through factors that are not fully understood harmful phytoplankton and their toxins are perceived to be on the increase in UK waters. Hence, it is necessary to better understand to factors that influence toxin production its vectoring by shellfish and the public health implications of shellfish toxicity. Research in this field in the UK is relatively underdeveloped and fragmented with little or no colllaboration between environmental and biomedical scientists. In this proposal we intend to hold a research workshop to integrate scientists, regulators, monitoring agencies and industry representatives with expertise in hamful phytoplankton and their effects. The worshop will allow the interdisciplinary sharing of knowledge and ideas and allow the hypothesis to be formulated for future environmental/biomedical colloborative projects. The production of a report will allow us to disseminate more widely the knowledge gained during the project.

浮游植物构成了海洋食物链的基础。大多数浮游植物都是良性的，确实对环境健康有积极的好处。然而，少数植物由于产生有毒物质，对人类、环境或经济都是有害的。这些浮游植物通常被称为有害藻华或赤潮。有毒的浮游植物可以通过滤食贝类摄取，这些贝类本身不会受到伤害，但会在组织中积累和浓缩毒素。如果这些贝类被人类食用，可能会发生严重的疾病。对浮游植物和贝肉的监测计划是将食用贝类对人类的健康风险降至最低的一种手段。此外，由于尚未完全了解的因素，在英国水域中，有害的浮游植物及其毒素被认为正在增加。因此，有必要更好地了解影响贝类毒素产生的因素及其通过贝类传播的途径，以及贝类毒素对公众健康的影响。在英国，这一领域的研究相对不发达和支离破碎，环境科学家和生物医学科学家之间很少或根本没有合作。在这项提议中，我们打算举办一次研究研讨会，将在有害浮游植物及其影响方面具有专业知识的科学家、监管机构、监测机构和行业代表整合在一起。Worshop将允许跨学科共享知识和想法，并允许为未来的环境/生物医学合作项目制定假设。编写一份报告将使我们能够更广泛地传播在项目期间获得的知识。
