Thursday morning – PM10 and PM2.5 are in further increases throughout Valpadana again especially between Piedmont, Lombardy and Emilia even above 150 mcg per cubic metre. The stable carbon dioxide is not more than 1000 mcg/m3 and NO2 is not more than 40 mcg. Higher values at night. Low concentrations in the rest of the peninsula.
Friday morning: Maximum concentrations are always in Valpadana but all diminished, PM10 and PM2.5 down to 80/100 micrograms per cubic meter. As CO decreased carbon monoxide does not exceed 600 μg and SO2 does not exceed 40 μg. More drops over the weekend. Low concentrations in the rest of the peninsula.
