Comparison of the Calculated AQHI (Dimensionless) Using Eq 1 for Chamber Mixtures Having High Oxidant and Low PM vs Low Oxidant and High PM Concentrations

SA	experiment	O₃contribution	NO₂ contribution (max)	O₃ + NO₂contribution	PM contribution	total^b
PM	MR044	10.2	33.8	44.1	63.1	107.2
PM	MR050	7.12	31.3	38.4	60.2	98.6
PM	MR051	7.56	28.7	36.3	58.8	95.0
PM	MR052	6.62	32.3	39.0	58.8	97.7
PM	MR055	5.41	29.7	35.1	56.9	92.0
O₃	MR059	26.1	74.5	100.6	2.48	103.0
O₃	MR062	23.9	69.8	93.7	2.48	96.2

NO₂ concentrations were an upper limit based on the NO_X measurement.

AQHI values calculated based on 1 min average concentrations over the duration of the individual experiments.
