toxic lead exposure study, from shooting

[jimmy the one]

Individuals who use firearms for work or recreation may be at risk for toxic lead exposure, say Yale clinical investigators. Utilizing Connecticut Dept of Public Health data, they report a rise in elevated blood-lead levels associated with the use and maintenance of firearms in the Journal of Occupational and Environmental Medicine.
The authors — became concerned when they started to see an increasing number of patients with high lead levels related to firearm use.

The case studies mirror data collected by the state’s Dept of Public Health as part of the Center for Disease Control and Prevention’s state-based Adult Blood Lead Epidemiology and Surveillance (ABLES) program. Between 2003 and 2013, the number of cases of elevated lead levels related to firing ranges rose from zero cases to 20, which represented 25% of all elevated lead levels reported to the state.

While the cause of the rise is not known, it is probably due to a combination of state educational outreach, an increased awareness of the risks of lead exposure from shooting, and increased exposure,
Young children are particularly vulnerable to contact with even low levels of lead, which is associated with increased risk for neurologic, cardiovascular, renal, and reproductive health problems.
.. clinicians should inquire about the use of guns in patients found to have elevated lead levels and consider testing family members, especially children.. http://news.yale.edu/2015/10/19/research-news-rise-lead-exposure-linked-firearms

Lead is actually just uranium end product after thousands years of radiative decay.
