Final answer:
The incorrect statement about the Air Quality Health Index (AQHI) is that it focuses solely on air pollution levels, as it also includes health-related advice and a wider range of quality indicators.
Step-by-step explanation:
The statement about the Air Quality Health Index (AQHI) that is not correct is: a) It focuses solely on air pollution levels. Unlike its predecessor, the Air Quality Index (AQI), which focused primarily on providing an assessment of the levels of pollutants in the outdoor air, the AQHI includes a wider range of air quality indicators and also provides health-related advice based on various pollution levels.
The AQHI was designed to better reflect the health risks associated with different levels of air pollution and to help individuals understand how to reduce those risks. It's an important tool for protecting public health, as it provides advice on how to adjust activities when air quality is poor, which is particularly crucial for sensitive groups like those with respiratory conditions.
