Rockström et al. proposed a set of planetary boundaries that delimitate a "safe operating space for humanity". One of the planetary boundaries is determined by "chemical pollution", however no clear definition was provided. Here, we propose that there is no single chemical pollution planetary boundary, but rather that many planetary boundary issues governed by chemical pollution exist. We identify three conditions that must be simultaneously met for chemical pollution to pose a planetary boundary threat. We then discuss approaches to identify chemicals that could fulfill those conditions, and outline a proactive hazard identification strategy that considers long-range transport and the reversibility of chemical pollution.
罗克斯特罗姆等人提出了一套界定“人类安全活动空间”的行星边界。其中一个行星边界由“化学污染”决定，但没有给出明确的定义。在这里，我们提出，不存在单一的化学污染行星边界，而是存在许多受化学污染控制的行星边界问题。我们确定了存在化学污染行星边界威胁必须同时满足的三个条件。然后，我们讨论了确定可能满足这些条件的化学物质的方法，并概述了一种主动识别危害的策略，该策略考虑了长途传输和化学污染的可逆性。
