I can't speak to them specifically, but in general, all plastics will 
contain various agents to keep them flexible, etc (depending on the 
properties desired by the mfr), and most will eventually leach.  Whether 
they are hazardous is a guess.  But do keep in mind that even relatively 
non-noxious common articles can be hazardous.  Garden hoses are 
notorious for making animals sick...and I can personally attest to the 
death of several hundred fish after having used a garden hose to 
suppliment about 15% of the water (after the dechlor of course).  Now I 
know they have special hoses for livestock watering...but even those 
have to have other chems in them in order for them to remain supple.
