问题 Which of the following is NOT likely to be covered by the standard?
The National Health Commission has initiated a revision of China’s current indoor air quality standard on Nov.30. The Indoor Air Quality Standard is a crucial parameter for health and the environment. Released in 2002, the current standard stipulates the level of major health-related factors and technical measuring methods regarding indoor air quality.
选项 A、The concentration of methanal in a newly redecorated house.
B、The proportion of carbon dioxide in a bedroom.
C、The PM 2.5 level in the city area.
D、Air sample collection techniques in office buildings.
答案 C
解析 特定信息的找寻与判断。根据原文可知，《室内空气质量标准》涉及的内容包括“the level of major health-related factors and technical measuring methods regarding indoor air quality”，即与室内空气质量相关的影响健康的指标水平，以及技术检测手段。选项A、B、D均为室内相关指标或检测技术，选项C为室外空气污染，不包含在标准规定范围内，故应选择选项C。
