High dust concentration in the atmosphere continued for a second day on Monday, with the Department of Labour Inspection advising vulnerable groups and workers to take precautions.
According to an announcement issued by the Depatment, the hourly concentration of respirable particles in ambient air with diameter less than 10 micrometers (PM10), was on Monday morning (9.00 local time, 7.00 GMT) between the maximum value of 313 μg/m3 with minimum value of 29 μg/m3.
Consequently it is expected that the average 24hour concentration will exceed the corresponding limit value of 50 μg/m3 (micrograms per cubic meter), as defined by the relative legislation.
On Sunday, March 2, the average 24hour concentration of respirable particles was between 193 μg/m3 and 328 μg/m3 depending on the location.
Because of the small size of the respirable particles and their negative effect on human health, the public and especially the vulnerable groups of population (children, old people and patients) are advised to avoid the outdoors and exercising in open spaces during this event.
Also it is recommended that the workers in open spaces use appropriate means of personal protection.
