This table shows that estimated percentage increases in the risk of death and 95% confidence intervals associated with IQR (interquartile range) increases in the daily average particulate matters using OPC (optical particle counter), [PM.sub.2.5] measured at individual monitoring site, and [PM.sub.10] from national monitoring stations with selected best lag time using single-pollutant model (these models include the following variables for day of week and smooth spline function of date, temperature, and relative humidity as well IQR of [CH.sub.234], [CH.sub.567], [CH.sub.2345678], [PM.sub.2.5], and [PM.sub.10] are 10.21 number/[cm.sup.3], 0.10 number/[cm.sup.3], 10.37 number/[cm.sup.3], 29.35[micro]g/[m.sup.3], and 40.44 [micro]g/[m.sup.3], respectively) in Seoul, Korea.
We used the eight-channel optical particle counter (LASAIR model 1002 unit; Particle Measuring Systems, Inc., Boulder, CO, USA) to measure number concentrations of particulate matter from 0.1 to 10 [micro]m in diameter with eight size ranges: 0.1-0.2 [micro]m, 0.2-0.3[micro]m, 0.3-0.4 [micro]m, 0.4-0.5 [micro]m, 0.5-0.7 [micro]m, 0.7-1.0 [micro]m, 1.0-2.0 [micro]m, and > 2 [micro]m.
We converted the real-time particle number concentration (number per liter) collected by the eight-channel optical particle counter after the coil was extinguished to mass concentration (milligrams per cubic meter) by assuming all particles have a spherical shape and unit density.
We monitored spatial and temporal distribution of 0.03 [micro]m particles using condensation particle counters (CPC), and for 1.5 and 3.2 [micro]m particles we used optical particle counters (OPC).
Real-time particle measurements were made using a LASAIR model 1002 eight channel optical particle counter (Particle Measurement Systems, Boulder, CO).
