PM2.5 (10 μg/m3 annual mean 25 μg/m3 24-hour mean)
The WHO Air quality guidelines are a set of evidence-based recommendations of limit values for specific air pollutants developed to help countries achieve air quality that protects public health. The first release of the guidelines was in 1987. Since then, several updated versions have appeared. This toolkit currently assesses countries against the 2005 guideline values (see here). The guidelines were updated more recently in 2021 (see here) and the legislation and policies presented in this toolkit will in the future be reassessed against these updated values.

North Macedonia

Decree amending and supplementing the Decree on limit values for levels and types of pollutants in ambient air and alert thresholds, deadlines for reaching limit values, tolerance margins for limit value, target values and long-term goals.

This amending Regulation establishes new criteria for managing air quality, focusing on alarm and information thresholds for PM10 concentrations. It introduces a definition of "stable weather conditions," updates section titles to address thresholds and deadlines, and mandates alerts when PM10 levels exceed limits for two consecutive days during stable weather. Emphasis is placed on systematic...
