▲摘要：大尺度化学监测数据评估需要化学物质、空间和时间三维信息的整合。在此，研究人员关联了美国6400万条地表水监测记录（涉及1900种化学物质，时间跨度为1958至2019年，覆盖31万个监测站点）以及3700万条分析检测限与体内/体外毒性阈值数据。研究发现，在约29.7万种潜在环境关注化学物质中，可用于回溯性风险评估的暴露数据不足1%。

The study suggests that existing Earth System Models (ESMs), by neglecting stem respiration thermal acclimation, may significantly overestimate the climate-carbon positive feedback effect. This new ...
