Especially important for non-resident hunters is practicing at altitude. Since scopes and equipment may get knocked out of alignment during transport, practicing at a range close to the destination provides a last minute equipment check.

The CSTE [ 48 ] makes the following recommendations actions for various blood lead levels in adults Table 2 :.
Ideally, recommendation triggering immediate cessation of exposure at shooting ranges should not be based on a single blood lead level measurement. Current public health recommendations call first for education and attention to risk factors that can mitigate future exposures. For occupational shooters and firing range workers, the U. Lead exposure of women and children have special characteristics that must be taken into account.
The needs relate to the effect of lead on future generations. For women the needs are related to the effect of lead on the developing fetus and post-natal exposure associated with breast-feeding. For children the special needs for low exposure are related to the extraordinary sensitivity of the developing organs of children. These concerns indicate the need for a margin of safety. Bone storage takes place because due to their similar ionic radius and charge lead is substituted for calcium.
Furthermore, when a woman becomes pregnant the fetus requires calcium and, depending on the dietary intakes, a proportion of calcium is derived from remodelling of the bones. Skeletal lead stores are released from the remodelling exposing the fetus during critical development windows [ 49 — 51 ]. Another consideration for female shooters is that when their BLL becomes elevated, they can pass the lead on to their children through breast milk [ 54 , 55 ]. Given the known lead contamination at firing ranges, intending-to- conceive, pregnant women, and nursing mothers should curtail exposure from shooting activities employed in the security, military and police, and recreational shooters and observe precautionary prevention.
Shannon [ 57 ] reported that children aged 14—16 who were competitive marksmen exhibited an average BLL of Blood lead levels observed in children from shooting activities are within the range known to cause long-term detrimental health effects [ 30 ]. Exposure of young females to lead is of particular concern because it is stored in their bones and can then be transferred to their developing fetus many years later when they become pregnant [ 49 — 51 ].
Law enforcement includes a number of services to protect and ensure the safety of citizens and the community. However, the adverse health effects, especially on the nervous system that are associated with elevated BLLs arising from firearm use are inconsistent with these ideals. Wang et al. It must be noted that the recommended PEL and action levels are not the only paths to controlling lead exposures. Kosnett et al. A critical issue is that biomonitoring is not primary prevention.
Biomonitoring only assesses the degree of exposure and potential health damage after exposure has taken place. Primary prevention requires curtailing lead exposure and maintenance of air quality. Several steps have been proposed above to minimize lead exposure. Recommendations to prevent occupational lead poisoning by shooters are provided by U. Government [ 62 ]. The recommendations appear as topics in school rifle team programs [ 63 ]. One of the challenges in a biomonitoring program is the frequency which shooters should have their BLLs monitored.
The Australian organisation Safe Work Australia has recently carefully made recommendations for multiple scenarios of blood lead testing frequency for workers exposed to lead in the work place [ 64 ]. Similar BLL testing frequency recommendations could be adopted for shooters exposed to lead in occupational settings such as law enforcement, military, security and shooting range workers.
Recreational shooters that shoot frequently could voluntarily use these blood lead testing frequency recommendations as a guide if they wanted to protect their health. In contrast to occupational environments where work clothes should not be taken home, lead dust can adhere to shooters clothes and potentially contaminate vehicles and homes. The CDC [ 65 ] measured carpet dust lead concentrations in FBI student dormitory rooms and in 14 non—student dormitory rooms at a firing range and training facility.
They observed that student dormitory rooms had significantly higher lead levels than non—student dormitory rooms, suggesting that the FBI students were contaminating their living quarters with lead.
The air lead table from Wang et al. Commercial ventilation companies claim they can meet guidelines i. Camfil air filters but no published studies supporting this achievement at firing ranges were located.
The literature gap raises questions about whether or not the guidelines can actually be achieved, especially the California guideline.
Further, as discussed in Special needs of women and children , meeting the guideline does not necessarily provide a margin of safety from lead exposure. Lead from projectile primers is a significant proximal source of lead exposure and uptake.
The development of primers is described by Brede et al. During the 19 th century primers were composed of mercury fulminate; however, the mercury fulminate was found to be too toxic to shooters. However, the results of some tests of the lead-free primers have proven disappointing, with significant variations in ignition timing, peak blast pressure, higher barrel frictions, and reliability in different climate conditions, compared with their lead-based equivalents [ 72 ].
The performance of lead-free primers are being tested by the U. Despite the critical observations, there is lead-free ammunition on the market. Widespread acceptance of the need to replace lead must take place, and until this happens one of the most significant health risks to shooters will remain lead-rich primers.
These bullets consist of copper rather than lead bullets. Bismuth has been proposed as a substitute for lead bullets but its environmental health impacts are poorly understood [ 77 ]. It is clear that firing lead-free bullets results in dramatic decreases in airborne lead exposures at firing ranges [ 78 ]. The use of copper-jacketed lead bullets does not appear to be a solution to a reduction in lead exposure because it results in only minor reductions in BLLs see Tripathi et al.
The United States Department of Defence DoD is aware of the health threat posed by lead exposure from small arms [ 69 ] and efforts are underway to test and replace lead in both primer and bullets [ 73 , 79 ].
Table 1 provides evidence-based information about the BLL sensitivity of shooters to lead dust at firing ranges. The major gap in preventing risk of lead exposure at firing ranges are the fundamental lead-bearing materials used for the explosive power and bullet projectiles. Primary prevention requires eliminating all lead materials in primers and bullets in order to end the dispersal of lead dust at firing ranges.
Shooting lead bullets at firing ranges results in elevated BLLs at concentrations that are associated with a variety of adverse health outcomes and the topic of health risk is an ongoing topic of study. Of major concern is the number of women and children among recreational shooters, who are not afforded similar health protections as occupational users of firing ranges.
Primary prevention of this risk requires development of lead-free primers and projectile bullets. Prevention includes better oversight of ventilation systems in indoor ranges and development of airflow systems at outdoor ranges, protective clothing that is changed after shooting, and cessation of smoking and eating at firing ranges. The mismatch between what is recommended for individuals by the U.
CDC is in stark contrast to the allowable levels for occupational exposure, and there are no real systematic biomonitoring programs for firing range users to measure cumulative health effects caused by persistent low and even high-level lead exposure.
Recreational shooters and the general public are provided no legal protections from lead exposures at firing ranges. In conclusion, while the past two decades have brought substantial improvements in analytical capabilities to detect lead in humans the literature evidence indicates that we fall far short of human health safety criteria in firing ranges of all types, and among occupational and recreational shooters.
