Particulate matter (PM) concentrations are above the threshold of 100 on China’s 500-point Air Pollution Index (API) that puts the air into the “slightly polluted” category. The same level might be considered “very polluted” in other parts of the world, and various Olympic teams have expressed concerns over the safety of their athletes.
颗粒物浓度超过空气污染指数100,空气质量列为“轻微污染”,同样的程度在世界其他地方要被认为是“严重污染”了,许多参赛队对运动员安全表示关注。
