Hong (Reports, 5 May 2017, p. 527) suggested that previous studies of the biogeochemically significant marine cyanobacterium showing increased growth and nitrogen fixation at projected future high CO levels suffered from ammonia or copper toxicity. They reported that these rates instead decrease at high CO when contamination is alleviated. We present and discuss results of multiple published studies refuting this toxicity hypothesis.
洪（Reports, 5 May 2017, p. 527）认为，先前研究表明，在预计未来高 CO 水平下，具有重要生物地球化学意义的海洋蓝藻表现出生长和固氮增加，但这些研究受到氨或铜毒性的影响。他们报告说，当污染减轻时，这些速率在高 CO 下反而下降。我们提出并讨论了多个已发表的研究结果，这些结果反驳了这种毒性假说。
