What is in the dross? There is a big market for dross, if you have a lot if it, say tons of it there are people that will haul it off for free, they will even sell it and ship it it overseas for processing. Or they will purchase the dross then ship it to be processed,

I've got a similar one that I use when doing any case cleaning operations, but one thing I've never seen addressed is the question of mask sanitation. Every time I use the mask and take it off there's a fair amount of condensation inside and I can't help but think that there must be a lot of germs along with it. Is it a good idea to sanitize the mask, even if I'm the only user? If so, what's the best way to do that? How often?
Blood lead level of concern
I'm new to this forum but I work as an industrial toxicologist and years ago I ran a federal-licensed lead laboratory. Blood levels 'of concern' and ''average blood lead levels in the adult US population' have both declined over the past 2-3 decades. In the early 1980's adult blood lead levels ranged as high as 15-20 ug/dl (non-workplace exposed) and were considered to be of concern only if they rose above 40 ug/dl (in most cases these were workers exposed to lead).
Over the years health authorities (CDC, etc.) have lowered the 'concern levels' for adults and childred to <10 ug/dl for adults and near the detection level for infants/children - mostly due to concern about neurotoxicity, learning disabilities, lower IQ, etc. in children.
The US average blood levels in persons not exposed in the workplace ranges from as low as <3ug/dl to >10/ug.dl in various regions and states in the US. It is often higher in older adults and certain geographic locations, associated with groundwater sources, etc. Recent studies showing increased risks of heart disease and other illnesses in adults with blood levels of >8 ug/dl appear to have 'bias' because these same people also have higher cholesterol, weight, lower income, and other adverse health factors independent of their blood lead levels.
I would not be overly-alarmed about a level of 8 ug/dl. You might get it checked periodicaly and look at possible sources. Do you know what you 'baseline' level was (prior to your hobby) ? If you cast lead bullets and the area is not 'well ventilated' it might be good to install a small exhaust hood above the work area. At the indoor range you might consider an appropriate 1/2-mask respirator with vapor cartridge (NIOSH 42 CFR 84).
Just some suggestions.

I'm thinking about switching to entirely liquid media to clean brass. The tumbler just gets too nasty.
It's of concern primarily because it's cumulative.

MSS,
No, I wish I did. Like other people said it could not be related to my Hobby. Will have the wife checked out soon. Since she never goes down to the basement and has only shot with me twice in 9 years her lead level should be low.
