NPHC Provides Guidance on How toAct When Air Pollution Increases
Specialists from the National Public Health Centre (NPHC) note that in recent days, increased air pollution levels have been recorded in some areas of Lithuania. NPHC recommends that residents monitor air quality indicators published on the website of the Environmental Protection Agency (AAA) and, if the limits are exceeded, follow public health recommendations. This is particularly important for individuals belonging to vulnerable groups.
We also remind that early childhood education and general education institutions should monitor air quality data. Outdoor activities for children should not be organized when air pollution levels exceed the established limits.
Health effects of particulate matter
Particulate matter (PM) is a mixture of solid particles and liquid droplets suspended in the air. It may contain various components, including acids, sulfates, nitrates, organic compounds, metals, soil particles, dust, soot, and other substances. PM may also include biological components such as allergens and microorganisms.
Larger particles (PM10) usually affect the upper respiratory tract, reaching the bronchi and causing coughing and sneezing, while finer particles (PM2.5) can penetrate deep into the lungs and enter the bloodstream. These particles may affect not only the respiratory system but also the cardiovascular system, impair internal organ function, and aggravate chronic diseases.
People with asthma and other respiratory or cardiovascular diseases, older adults, infants, children, and pregnant women are considered a vulnerable (risk) group that is most affected by increased ambient air pollution and should take extra precautions.
Recommendations during periods of increased air pollution
- Individuals belonging to risk groups are advised to stay away from visible sources of pollution outdoors (busy streets, smoking chimneys, areas with noticeable odours). If this is not possible, it is recommended to remain indoors and monitor health conditions.
- People exercising outdoors are advised to choose locations farther from pollution sources and adjust the duration of physical activity according to their well-being.
- Those who must remain in polluted environments for extended periods due to work or other reasons are advised to wear respiratory protective equipment, taking into account the duration of exposure specified in the equipment’s technical requirements.
- Use public transport whenever possible.
- Do not light bonfires or burn waste in gardens or suburban areas.
- Clean indoor premises more frequently using wet cleaning methods.
- Monitor your health, and if you feel unwell, consult your family physician.
