Seasonal Variability of Resuspension

Particulate air pollution in cities is caused by a variety of sources. One the less-studied contributors wind-induced particle resuspension. As wind speed increases, particles are removed from surfaces. These cause an increase total concentration air. It known that 10-2.5 μm size can be resuspended (PM 10-2,5 ). Modern emission monitoring also allows fine 10, 2.5 and 1 size. The fractions then sorted into PM , 2,5-1 . When breathed in, different sizes various serious health risks. This paper focuses on identification resuspension process data processing method. Data measured automatic used. confirmed dominated fraction However, evident with increasing speed. Although smaller than it more severe due to respiratory deposition dose. has behaviours during year. dominantly summer months. In winter, other hand, proportion 2.5-1 which may related heating season
