A weak light pressure system is affecting the area, with more dust in the atmosphere at intervals, the met office said on Friday.
The Labour Ministry issued a new announcement warning that dust levels are above average and urged vulnerable groups to avoid outdoor activities — the second such warning in two days.
In a statement on its website, it said that at 7:00 am the hourly concentration of respirable particles in ambient air with diameter less than 10 micrometres (PM10), were between the maximum value of 243 μg/m3 and minimum value of 93 μg/m3 (micrograms per cubic metre).
Consequently it is expected that the average 24 hour concentration will exceed the corresponding limit value of 50 μg/m3 as defined by the relative legislation.
Yesterday, the average 24hour concentration of respirable particles was between 38 and 78 μg/m3 depending on the location, it added.
“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, older people, and patients) are advised to avoid outdoor activities and exercising in open spaces during this event,” the Labour Ministry said.
Employers are required to take the appropriate measures (organisational or technical) after assessing the risks that their employees are facing while working in open spaces. Moreover, it is recommended that the workers in open spaces use appropriate means of personal protection, it said.
More information on the measured pollutant concentrations is available online through the dedicated website maintained by DLI at www.airquality.gov.cy, and also through the free application “Air Quality Cyprus” on the Google Play and iOS App Store.
