Guest guest Posted September 9, 2006 Report Share Posted September 9, 2006 Recycled rubber surfaces are found commonly today on many high school and collegiate running tracks. Have not seen it called artificial turf before and never noticed any smells associated with these tracks, although the PAHs detected were probably too low to have noticeable smell anyway. Zinc is a common metal founds in tires probably in the steel belted radials. Nonetheless the concentrations of PAHs are in the low ppm range which are significant for these organics and it also appears as if the rubber material has been heated to produce such PAH concentrations. Benzo(a)pyrene had the highest concentration in the samples collected and is more carcinogenic than benzene. More and more recycled rubber products are available today and while we need to recycle as much as possible, it's questionable to use a product emitting PAHs even in the low ppm range.

Guest guest Posted September 9, 2006 Report Share Posted September 9, 2006 Questionable? Especially when one considers that they are used inside athletic facilities, tracks, etc. Ever play soccer?
