大气中二氧化碳浓度的增加正在导致海洋酸化，改变碳酸盐化学，从而对海洋生物造成后果。在这里，我们表明，与环境二氧化碳水平相比，在预计本世纪末二氧化碳浓度升高的情况下，OA使浮游植物中酚类化合物的产量增加了46%-212%。同时，在单一物种或混合浮游植物组合中，在二氧化碳浓度升高的情况下，线粒体呼吸速率增加130-160%。当摄食在OA下生长的浮游植物细胞时，浮游动物群落的酚类化合物含量明显更高，约为28%-48%。初级和次级生产者有毒酚类化合物增加积累的功能后果有可能对海洋生态系统和海产品质量产生深远影响，海洋逐步变化可能会影响渔业。大气中二氧化碳浓度的增加会导致海洋酸化，从而改变海洋化学环境，给海洋生态系统带来未知的后果。在这里，高等人。研究表明，海洋酸化增加了浮游植物和浮游动物中的酚类化合物水平，这意味着食物链的影响。
Increasing atmospheric CO2 concentrations are causing ocean acidification (OA), altering carbonate chemistry with consequences for marine organisms. Here we show that OA increases by 46–212% the production of phenolic compounds in phytoplankton grown under the elevated CO2 concentrations projected for the end of this century, compared with the ambient CO2 level. At the same time, mitochondrial respiration rate is enhanced under elevated CO2 concentrations by 130–160% in a single species or mixed phytoplankton assemblage. When fed with phytoplankton cells grown under OA, zooplankton assemblages have significantly higher phenolic compound content, by about 28–48%. The functional consequences of the increased accumulation of toxic phenolic compounds in primary and secondary producers have the potential to have profound consequences for marine ecosystem and seafood quality, with the possibility that fishery industries could be influenced as a result of progressive ocean changes. Increasing atmospheric CO2 concentrations causes ocean acidification, which alters marine chemical environments with unknown consequences for marine ecosystems. Here, Gao et al. show that ocean acidification increases levels of phenolic compounds in phytoplankton and zooplankton, implying a food chain impact.
