Release of PAH from Secondary Products Made from End-of-Life Tire Recyclates into 20% Aqueous Ethanol as Assessment of Human Dermal Absorption

Compliance with the legal limits set at European level for content of polycyclic aromatic hydrocarbons (PAH), which are harmful to human health and environment, is central importance recycling rubber, particularly end-of-life tires (ELT), into secondary products, e.g., elastic fall protection mats or anti-slip transport sector. However, different regulations associated analytical methods apply newly produced on one hand products made from ELT other. Given these discrepancies, can potentially contain levels PAH, be problematic when reused in consumer products. The total PAH content, however, not without doubt a reliable risk indicator, should ultimately based primarily transfer substances product skin beings their release environment. Accordingly, additional studies required determine extent migration-based measurements more suitable assessment how correlates migration. Complementing recently published results types ELT, this study investigates range typical materials composed entirely partly ELT. In present study, migration tests 20% aqueous ethanol were applied, methodology that has been shown previous investigations by others reflect exposure well, resulting rates determined.
