What does PAH stand for?
BfR and ZEK have developed under the REACH regulation a restriction proposal for consumer products. The restrictions are divided into three categories based on how much contact the products are likely to have with skin or food. TENTE’s castors and wheels belong to category 3, which covers materials with a predicted skin contact time of up to 30 seconds or without any skin contact. In this category, up to 20 mg benzo[a]pyrene per kg and a total of 200 mg/kg of all 16 affected PAHs are permitted.
The 16 "priority pollutants" in the PAH group
The following hydrocarbons are among the PAHs affected by the BfR's restriction proposal:
+ Naphthalene (C10H8)
+ Acenaphthylene (C12H8)
+ Acenaphthene (C12H10)
+ Fluorene (C13H10)
+ Phenanthrene (C14H10)
+ Anthracene (C14H10)
+ Fluoranthene (C16H10)
+ Pyrene (C16H10)
+ Chrysene (C18H12)
+ Benzo[a]anthracene (C18H12)
+ Benzo[b]fluoranthene (C20H12)
+ Benzo[k]fluoranthene (C20H12)
+ Benzo[a]pyrene (C20H12)
+ Indeno[1,2,3-cd]pyrene (C23H13)
+ Dibenzo[ah]anthracene (C22H14)
+ Benzo[ghi]perylene (C22H12)
The substances were initially defined by the US Environmental Protection Agency (EPA) as so-called priority pollutants, which is why they are often referred to as "EPA-PAH".
TENTE products all comply with the directives concerning the concentration of PAH.
