为何新标准未调整臭氧限值？王书肖解释，PM2.5是当前全球空气污染相关疾病负担的首要驱动因素，因此新标准的修订重点关注PM2.5。旧标准中O3日最大8小时平均浓度一级和二级限值分别为100微克/立方米和160微克/立方米，分别与世卫组织2021年发布的新版《全球空气质量指南》指导值和第一阶段过渡值一致。可见，我国臭氧浓度限值与国际先进水平的差距远小于PM2.5。
Today, this ability to maintain a stable body temperature—called homeothermy—is known to exist among myriad species of mammals and birds. But there are also some notable exceptions. The body temperature of the fat-tailed dwarf lemur, for example, can fluctuate by nearly 45°F (25°C) over a single day.
