Somebody on another forum I am a member of has asked a question that has sparked a debate about lead.
In effect, he has allowed moisture to get to his lead pellets and an oxide has formed on the outside. His initial question was based on whether this effects their performance but the thread has transformed into one about the dangers of lead oxide (not my doing I'd like to point out!)
Does anyone know anything about this?
My gut says the quantities involved are probably not high enough to get worried about but it's not a subject I'm particularly clued up on.

Did a lot of work on lead as an undergraduate a long time ago now, but here goes.
Once removed from its ore lead is toxic in all forms, organic compounds particularly as they are easily absorbed onto the body. The body cannot excrete lead so it is an accumalitive poison and since it can't be excreted it gets stored in the eskeleton.
Children are partcularly susceptible to lead as it affects enzymes involved in brain development.
The up shot (excuse the pun) is, if you're handling lead or any of it's compounds in a non- commercial use it's probably sensible to seek a safer altenative. If not available, practice good hygiene and wash hands before eating, drinking etc.

Thanks Goose,
Learnt something from that as I didn't know it was accumalitive!

Goose.
From my studies I understood that 5-10% of ingested lead gets aborbed but of course that depends on its form (powder, pellets, from fingers). Once ingested it has a half life of 25 years from the bones, 25 days from blood and 40 days from soft tissue

M,
I did say it was a long time ago, but from memory it's complex chemistry and is dependent on the the compounds of lead involved and the route of entry.
Some lead can be excreted but I beleive this is relatively small about 5%, the rest gets stored mainly in the skeleton.

Hi Goose, happy to take your word for this. My info is from my diploma notes and my background is in electronic engineering so you are better placed than me to provide informed opinion :)

What sort of effects does it have on health?

Safety Smurf,
Health effects can be complex and very serious but as ever it is all about the type, length, level of exposure etc.
See this OSHA page for an overview. http://www.osha.gov/SLTC/lead/recognition.html
I worked many, many years ago with tetra-ethyl-lead compounds used as an additive for high octane motor spirit (petrol). We used to decant and pump the stuff into the storage tanks using a hand pump. It raised the octane rating up to 115/145 for use in airplane engines!!!
Flying high--you bet! I think I am still here to tell you about it but maybe it did affect my mental capacity after all:)

I'd like to beleive that most if not all anglers are aware of the H&S, Environmental and the dangers to wildlife asociated with lead these days and use an alternative method for weighting their baits.
regards
Frank
