2.   This Directive lays down limit values, target values, average exposure reduction obligations, average exposure concentration objectives, critical levels, alert thresholds, information thresholds and long-term objectives. Such air quality standards, which are set out in Annex I, shall be regularly reviewed in accordance with Article 3, in line with WHO recommendations.
