该限制规定,在人造草坪球场中用作填充材料或以松散形式用于运动场或体育场馆的橡胶颗粒和覆盖物中,限制范围内的八种多环芳烃(REACH 8 种多环芳烃)的总含量不得超过 20 毫克/千克。对于本限制条目未涵盖的其他用途的橡胶颗粒和覆盖物,其多环芳烃的最大含量限值是多少?

Question (EN)
This restriction sets to 20 mg/kg the maximum content for the sum of the eight PAHs in the scope of the restriction (REACH 8 PAHs) in rubber granules and mulches used as infill materials in synthetic turf pitches or in loose form in playgrounds or sport application. What is the maximum content limit for PAHs in rubber granules and mulches used in other applications not covered by this restriction entry?

答案(中文)
REACH 附件 XVII 第 50 条涵盖的 PAH 物质(即苯并 (a) 芘、二苯并 [a,h] 蒽、苯并 [e] 芘、苯并 [a] 蒽、屈、苯并 [b] 荧蒽、苯并 [j] 荧蒽和苯并 [k] 荧蒽)均被归类为 Carc. 1b(协调分类)。这些物质在混合物(例如橡胶颗粒和覆盖物)中的浓度限值由 REACH 附件 XVII 第 28 条限制条款规定,该条款规定了 Carc. 1A 和 Carc. 1B 物质在混合物中供公众使用时的最高浓度限值。根据第28条,第50条所列PAH的单独浓度限值如下:苯并[a]芘和二苯并[a,h]蒽的限值分别为0.01重量%(100毫克/千克);苯并[e]芘、苯并[a]蒽、屈、苯并[b]荧蒽、苯并[j]荧蒽和苯并[k]荧蒽的限值分别为0.1重量%(1000毫克/千克)。根据这些限值的具体数值,并应用CLP加和性规则,得出REACH-8种PAH的总和限值约为387毫克/千克。该数值已在2021年7月21日颁布的欧盟委员会条例2021/1199(修订REACH附件XVII第50条)第(3)段中得到确认。
Answer (EN)
PAHs substances covered by entry 50 of Annex XVII to REACH (i.e. benzo(a)pyrene, dibenzo[a,h]anthracene, benzo[e]pyrene, benzo[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[j]fluoranthene and benzo[k]fluoranthene) are all classified as Carc. 1b (harmonised classification). The concentration limit for these substances in mixtures (such as rubber granules and mulches) is established in restriction entry 28 of Annex XVII to REACH which sets maximum concentration limits for use of Carc. 1A and Carc. 1B substances in mixtures for the general public. According to entry 28, individual concentration limits for PAHs listed in entry 50 are 0.01 % by weight (100 mg/kg) for benzo(a)pyrene and dibenzo[a,h]anthracene and 0.1 % by weight (1000 mg/kg) for benzo[e]pyrene, benzo[a]anthracene, chrysene,benzo[b]fluoranthene, benzo[j]fluoranthene and benzo[k]fluoranthene. Based on their specific limits and applying the CLP additivity rule, a limit of approximately 387 mg/kg is derived for the sum of REACH-8 PAHs. This value finds confirmation in recital (3) of Commission Regulation 2021/1199 of 21/07/2021 amending entry 50 of Annex XVII to REACH.
