High levels of particulate pollution reported
Suspended particulate levels (PM10) registered high at air quality monitoring stations across the city this morning. The dust originates from traffic; when streets are dry and winds are light, it is stirred up more easily and stays airborne. At noon, PM10 levels reached 93.4 micrograms per cubic meter at the Grensásvegur monitoring station. For comparison, the 24-hour public health limit is 50 micrograms per cubic meter. Crews applied dust suppressants early Wednesday morning, but due to current conditions, these efforts are not enough to keep pollution within acceptable limits. Dust suppression is a joint effort between Reykjavík City and the Icelandic Road and Coastal Administration.
Light winds are forecast for tomorrow, increasing the risk of continued pollution. The forecast calls for little precipitation until the middle of next week. Authorities are considering additional dust suppression efforts to reduce pollution.
Vulnerable individuals should limit time outdoors
People with respiratory conditions, older adults and children should avoid extended outdoor activities and limit physical exertion. The public is encouraged to reduce private vehicle use when possible by postponing non-essential trips, using public transportation, carpooling, or choosing other environmentally friendly travel options. Companies are urged to encourage employees to work from home on days with high particulate levels when possible and reduce driving when feasible.
Reykjavík Public Health closely monitors the city's air quality and issues warnings and guidance when needed. You can track suspended particulate levels and other pollutants at loftgæði.is.. The site displays a map of monitoring stations in Reykjavík and other locations across the country.
Microscopic dust particles
Suspended particulates are microscopic dust particles that can easily enter the respiratory system. The public health limit is set at 50 micrograms per cubic meter over 24 hours for PM10 (particulates measuring around 10 micrometers in size). The main sources of suspended particulates are road dust from worn asphalt, soot primarily from diesel combustion, soil particles, salt, ash, and other materials.
