[21] also found that the concentration of indoor PM10 in day care centers was almost similar to the mean concentration of indoor PM10 in areas near the main road and industrial area (69.8 [micro]g/m3 and 68.8[micro]g/m3, respectively) and slightly lower in day care centers in residential area.
"High levels of PM10 can cause diseases such as lung cancer," warned Dr Pierson.
The WHO tabulation ranks cities by the annual mean volume of PM10. meaning that a particular bad day or season is averaged out over the year, giving a better idea of the long-term impact on residents.
Patients in cities with clean air were more sensitive to pollution rises, with each 1 mg/m3 increase in PM10 concentration linked to 0.22 additional PCIs per week.
The researchers found that an increase of 10 [micro]g per cubic meter in the two-day moving average of PM10 concentration correlated with increases of 0.44, 0.36, and 0.47 percent in daily all-cause mortality, cardiovascular mortality, and respiratory mortality, respectively.
Most PM10 particles will settle down eight hours after becoming airborne, while PM2.5 particles take at least 36 hours to settle.
The measurements refer to particles that are smaller than 10[eth]-m (PM10).
Tuesday - 114 micrograms per cubic meter of air (ug/m3) for PM10 and 113 ug/m3 for PM2.5.
Similarly, maximum PM10 concentration was recorded at Gutte Wala (782 ugm-3) and Chak 215 RB (893 ugm-3), while maximum PM2.5 concentration was observed at Madina Food Mill (621 ugm-3) and Chak 215 RB (654 ugm-3).
Mainly coming from vehicles on the road, particularly diesel engines, particulate matter (PM10 and PM 2.5) and nitrous oxides (NO2) are a cause of huge concern for health and council bosses.
