[QUOTE="JPIVEY, post: 1051739, member: 22193"] [b]Also be aware of this[/b] BLM says arsenic of concern 12:24 AM PDT on Wednesday, April 26, 2006 By DAVID DANELSKI The Press-Enterprise the dangers Arsenic is a poisonous, naturally occurring element, often left over when metals are extracted from ore. Airborne exposure can irritate the throat and lungs. Ingesting it can cause nausea, decrease blood-cell production, damage blood vessels, cause irregular heartbeats and death. Long-term exposure can cause cancer. High levels of arsenic left over from a hundred years of mining near the northwest corner of San Bernardino County has federal officials worried about the potential health risk to residents and off-roaders. Soil samples in recent months showed "extremely" high arsenic concentrations near Red Mountain, Johannesburg and Randsburg, desert towns rooted in the area's gold and silver industry. About 500 people live in the remote communities, and the territory is an increasingly popular off-road recreation spot. The U.S. Bureau of Land Management is considering closing dirt roads where motorcyclists and other off-roaders kick up potentially hazardous dust. People could be exposed by breathing the dust or by skin contact. The U.S. Environmental Protection Agency has asked the bureau to contain or clean up the arsenic from processed gold and silver ore, known as mine tailings. The waste piles are visible throughout the area. [/QUOTE]
