Web1 jun. 2024 · In this approach, the AQHI was scaled to 0–10 by dividing it by the maximum value of E R t and then multiplying it by 10 ( Du et al., 2024 ). We constructed the standard AQHIs for cause-specific mortality, namely nonaccidental, cardiovascular, and respiratory mortality. 2.2.1.2. CRI method WebHow is a community’s AQHI calculated? The Air Quality Health Index (AQHI) is based on the relative risk posed by a combination of common air pollutants that are known to harm human health.
