Royal Decree 846/2026, in force since 24 October 2026, transposes Directive (EU) 2024/869. Diisocyanates (found in many polyurethanes, adhesives and waterproofing products) get new limits of 6 µg NCO/m³ (8 h) and 12 µg NCO/m³ (short term), with transitional values of 10 and 20 µg until the end of 2028. The biological limit for lead drops to 15 µg/100 ml of blood, with stronger health surveillance.
