Answer :
Final answer:
The statement that an AQI value of 93 is the sum of pollutants is false; the AQI is a calculated value reflecting the highest level of health concern from multiple pollutants.
Explanation:
The claim that an AQI value of 93 indicates that the sum of the pollutants present gives an AQI value of 93 is false. The AQI value does not represent a simple sum of pollutants, but rather, it is a complex calculation designed to represent the overall level of air pollution and its potential effects on health. The AQI takes into account the concentrations of multiple pollutants, including ground-level ozone, particulates (also known as particle pollution), among others. Each of these pollutants can affect the AQI value differently, and the index is structured to provide a measure that reflects the highest level of health concern among the pollutants present. AQI values below 100 are generally thought to be satisfactory, whereas values above 100 are considered to be unhealthy for sensitive groups, eventually reaching levels that are unhealthy for all with increasing values.
