[Community_garden] Using Trex for Raised Beds

[Andrea Jadwin]

Interested in learning whether other community gardeners have data on  
using composite material (Trex or others made out of recycled wood  
and plastic) for raised beds.  Specifically, whether there is known  
danger associated with growing and eating vegetables raised in these  
types of beds.

I have searched the web somewhat but have not found strong scientific  
information against it.  I'm not really interested in anecdotal  
theories or political leanings:-)

Would appreciate help from anybody who can point me towards solid  
information about possible toxicity - or not.

Thanks!
