well it appears there are three camps....those that know lead contamination, those that don't and those that don't care.
lead can get into the body in the following usual ways:
ingestion
inhalation
absorption
The first two are the most significant for shooters. if you smelt your own lead, you need to protect yourself. if you reload, handle bullets with exposed lead, clean bullet traps, shoot indoors, shoot in confined areas, then you need to protect yourself. Gloves are best and consider a HEPA mask.
the best way to avoid ingestion is to have clean washing practices immediately after shooting is completed and before you ingest anything - liquids, food, gum, etc. if you drink during a match, you should wipe you hands.
to avoid inhalation, anywhere there may be lead dust or vapour, then wear a HEPA mask.
if you do a lot of shooting, get your blood lead levels checked every year - you will likely have to pay for it - my doc charges 30.00 per test. if you have had elevated levels more than once, you may want to consider a bone scan....as your Blood lead level drops, it doesn't totally leave your body, it settles in your bones. Just because your level has gone down, doesn't necessarily mean you are in a safe zone. Consider being referred to a doctor who specializes in lead contamination - usually a doctor who works with industry (battery factories). I know of a doctor in Richmond Hill if you need one and you are in the GTA.
I know this as I have had direct contact with the running of a shooting range since 1996. I am well versed in the dangers involved. If you think we are sissy's then go about basking in your ignorance. The evidence is overwhelming and readily available - just google it.
