“…High risk of heart disease, kidney damage, and dementia.”

“A review of the epidemiologic and toxicologic data allowed the committee to conclude that there is overwhelming evidence that the OSHA standard provides inadequate protection for DOD firing-range personnel and for any other worker populations covered by the general industry standard. Specifically, the premise that maintaining BLLs under 40 μg/dL for a working lifetime will protect workers adequately is not valid; by inference, the OSHA PEL and action level are also inadequate for protecting firing-range workers. The committee found sufficient evidence to infer causal relationships between BLLs under 40 μg/dL and adverse neurologic, hematopoietic, renal, reproductive, and cardio-vascular effects. The committee also found compelling evidence of developmental effects in offspring exposed to lead in utero and during breastfeeding, and this raises additional concerns about exposures of women of childbearing age….

Despite changes in military tactics and technology, proficiency in the handling of weapons remains a cornerstone in the training of the modern combat soldier. Modern military forces are trained on one or more small arms, including handguns, shotguns, rifles, and machine guns. Many of the projectiles used in military small arms contain lead. Exposure to lead during weapons training on firing ranges therefore is an important occupational-health concern.

Lead is a ubiquitous metal in the environment, and its adverse effects on human health are well documented. The nervous system is an important target of lead toxicity, which causes adverse cognitive, mood, and psychiatric effects in the central nervous system of adults; causes various peripheral nervous system effects; and has been linked to neurodegenerative diseases. Lead exposure also causes anemia, nephrotoxicity, a variety of adverse reproductive and developmental effects, small increases in blood pressure and an increased risk of hypertension particularly in middle-aged and older people, and various effects in other organ systems, including joint pain and gastrointestinal pain (ATSDR 2007; EPA 2012; NTP 2012).”

1After the committee completed its evaluation and released the prepublication draft of this report, the Army submitted data on BLLs for Department of the Army civilian personnel working at shoot houses. The Army’s submission can be obtained by contacting the National Research Council’s Public Access Records Office at (202) 334-3543 or paro@nas.edu.”

 

• Characterization of exposure on firing ranges. The committee focused its attention on airborne lead exposures that are most likely to occur on DOD firing ranges. Measurements and evaluations conducted at DOD ranges were used primarily and were supplemented with information on other types of firing ranges.
