拟柱孢藻(Cylindrospermopsis raciborskii)及其毒素的研究进展与展望

Progress and prospect in the study of Cylindrospermopsis raciborskii and its toxins

随着水体富营养化程度的加剧,淡水蓝藻水华在全球范围内频繁暴发.拟柱孢藻(Cylindrospermopsis raciborskii)作为一类有害水华蓝藻,具有一定的产毒能力和较强的入侵性,日渐受到人们的广泛关注.近年来,拟柱孢藻不断由热带、亚热带地区向温带地区扩张,并在众多水体中出现暴发现象,若其毒素进入到饮用水中,无疑将对人类健康造成潜在威胁.本文从拟柱孢藻的分布演变、生态生理特征、毒性、检测和去除等研究前沿方面进行了综述,并对相关研究领域进行展望,为进一步研究拟柱孢藻的生态毒理、有效控制和去除提供科学依据.

With the aggravation of water eutrophication, harmful cyanobacterial bloom in fresh water becomes more and more seri-ous on a global scale. Cylindrospermopsis raciborskii, a noxious cyanobacterial species that can form blooms in fresh water, has gradually received widespread attention for its potential ability of toxin production and strong invasiveness. In recent years, Cylin-drospermopsis raciborskii has spread from the tropics and subtropics to temperate zones with associated blooms in many water bodies.If the toxins come into drinking water, it will undoubtedly pose a potential threat to human health. In this review, recent literatures concerning its geographic distribution, ecophysiology, toxicity, detection and removal processes are summarized. Meanwhile, we discussed the future research directions in related field, which will provide some scientific information for further studies on the eco-logical toxicology, effective controls and removal of Cylindrospermopsis raciborskii.
