Cylindrospermopsis raciborskii is a planktonic freshwater cyanobacterium that is becoming increasingly prevalent in water bodies worldwide. During a survey of toxic cyanobacteria in New Zealand, C. raciborskii was identified in a sample collected from Lake Waahi (Waikato). This is the first identification of this species in New Zealand. Liquid chromatography‐mass spectrometry and liquid chromatography‐tandem mass spectrometry were used to confirm the presence of the cyanotoxins cylindrospermopsin (CYN) and deoxy‐cylindrospermopsin (do‐CYN). Detection of CYN and do‐CYN demonstrates that C. raciborskii is a now a species of concern in recreational, stock drinking, and potable water supplies in New Zealand. 相似文献

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. 相似文献
