Levels of suspended particulates and nitrogen dioxide increase
Suspended particulate levels (PM10) registered high at air quality monitoring stations across the city this morning.
The dust comes from traffic but may also come from more distant sources, since moderate winds are present and readings remain high at stations far from major traffic routes. Dust suppression activities are planned for today to reduce airborne particles. Dust suppression is a joint effort between Reykjavík City and the Icelandic Road and Coastal Administration. Rain is forecast for the coming days, which should help reduce pollution levels as the week goes on.
Suspended particulates are the finest type of dust particles that easily enter the respiratory system. Health protection limits are set at 50 micrograms per cubic meter per 24-hour period for PM10 (suspended particles about 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.

People with respiratory sensitivities, older adults and children should avoid prolonged outdoor activities and limit physical exertion. Residents are encouraged to reduce personal vehicle use when possible, postpone non-essential trips, use public transportation instead, carpool or choose other environmentally friendly transportation options. Officials also urge companies to encourage employees to work remotely if possible and to reduce driving.
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.
The Environment Agency's air quality website rates air quality using these color codes:
Very good = Little to no air pollution. Likely no health effects.
Good = Minor air pollution. Little to no health effects.
Acceptable = Some air pollution. Very sensitive individuals and people with asthma or other underlying lung and heart conditions may experience symptoms due to higher levels of air pollutants.
