Table 1. Sample details of dust specimens collected during five time points during three seasons from two sites in Kuwait.
Sampling performed through high stage cascade impactor.

*Numbers 1–7 represent the stage of the impactor. Dust fractions impacted on stage 1–5 fall under the respirable category, whereas stage 7 represents the inhalable portion of the air-borne dust. Sampling was done for a period of 48 hours. The total suspended PM in each size fraction were between the aerodynamic diameter (Dp) sizes ranges of < 0.39 (backup high volume filter-stage 7), 0.39 to 0.69 (stage 6), 0.69 to 1.3 (stage 5), 1.3 to 2.1 (stage 4), 2.1 to 4.2 (stage 3), 4.2 to 10.2 (stage 2) and > 10.2 μm (stage 1).
