Abstract LeDuc JF, Christensen VG, Maki RP. 2020. Rapid assessment test strips: effectiveness for cyanotoxin monitoring in a northern temperate lake. Lake Reserv Manag, 36:444–453. Precise and rapid methods of determining toxin levels are needed in lakes used for recreation and drinking water to facilitate a quick risk assessment during cyanobacteria blooms. Therefore, we evaluated rapid-assessment test strips, a newer technology for estimating the toxicity of cyanobacterial blooms, in Kabetogama Lake, a popular recreational area of Voyageurs National Park in northern Minnesota (USA). Sixty-seven percent of the test strip results matched results of enzyme-linked immunosorbent assays, with individual toxin results of 75% (anatoxin-a), 80% (cylindrospermopsin), and 64% (microcystin). These results provide some evidence that the test strips may be effective for rapid detection of toxins in northern temperate lakes, although improvements to the test strips may be beneficial. Despite the intensive processing required and uncertainty of some results, the availability of a rapid and inexpensive field method allowed us to sample opportunistically in the fall, when we documented dangerously high toxin concentrations at places where waterfowl-retrieving dogs may be at particular risk of exposure.

快速评估试纸：北温带湖泊中蓝藻毒素监测的有效性

摘要 LeDuc JF、Christensen VG、Maki RP。2020. 快速评估试纸：北温带湖泊中蓝藻毒素监测的有效性。湖保护区管理，36：444-453。需要在用于娱乐和饮用水的湖泊中使用精确和快速的方法来确定毒素水平，以促进蓝藻大量繁殖期间的快速风险评估。因此，我们在美国明尼苏达州北部航海者国家公园的热门休闲区 Kabetogama 湖评估了快速评估试纸，这是一种用于估计蓝藻水华毒性的新技术。67% 的试纸结果与酶联免疫吸附测定的结果相匹配，单个毒素结果为 75%（anatoxin-a）、80%（圆柱藻毒素）和 64%（微囊藻毒素）。这些结果提供了一些证据，证明测试条可能有效地快速检测北温带湖泊中的毒素，尽管对测试条的改进可能是有益的。尽管需要密集的处理和某些结果的不确定性，但快速且廉价的现场方法的可用性使我们能够在秋季机会性地取样，当时我们记录了在水禽检索犬可能有特别暴露风险的地方危险的高毒素浓度.
