Zeb :

I have always wondered about those lead weights. But they're so convenient 
that I sometimes use them. About 6 months ago I used some to attach some 
Java ferns to a piece of driftwood. By now the ferns have covered the wood 
to a large extent (a very nice effect). However, at the point where I had 
put the lead into a crevice into the wood, there was a nice ring of orange 
around it, and the java ferns did not grow there. Just like those 
antibiotic pads on agar plates. So, it seems there is some toxic effect, at 
least when the lead comes into contact with certain substances (that would 
for instance be found in driftwood). I now tie my java ferns onto things 
with nylon fishing line.
