Shooting ranges

When the data have been screened and performance calculated, don t be surprised if all the points plot like a tai et in a shooting range, perhaps with a tighter circle rather than describing the complete compressor curve. 

The purpose of this test is the same as the previous one. The critical volume is the sphere diameter of a substance, below which it is impossible to obtain detonation conditions under the influence of a firing blasting charge. These tests can only be conducted on shooting ranges and sometimes with large substance quantities.

Satake and coworkers131 studied lead accumulation and location in the shoots of the aquatic liverwort, Scapania undulata, in stream water (Pb content, 20 p-gl-1) at a mine in England. The lead concentration in the shoots ranged from 7 to 24 mgPbg-1 on a dry weight basis, giving an enrichment ratio of 3.5 x 105 — 1.2 x 106. Lead was localized in the cell wall131. 

Western Environmental Science and Technology (WEST) had developed an ex situ soil washing technology designed for the treatment of lead-contaminated soil. This technology was particularly developed for use at shooting ranges.

For example/ inoculum consisting of Sclerotinia sclerotiorum-infested wheat kernels and sclerotia were hand-broadcast at five different locations to control Canada thistle FCirsium arvense (L.) Scop.] (21). The mean percentage of dead shoots ranged from 20% to 80% which showed a dependence upon location and data collection times. However/ at all five sites/ the percentage of dead shoots was significantly higher in the treated than in the control plots. 

Just as police officers need to maintain their weapons and routinely put in time on a shooting range, analytical chemists must always ensure that their instruments are calibrated and functioning properly. In police work, even if the butler confesses, without the proper police procedure, the most damning evidence can be thrown out. In the same manner, analytical chemists must be able to defend their results by reporting parameters such as confidence limits instrument noise levels, and significant figures.

In homicides committed with a gun it is important to find out the shooting range. A great deal of corroborative evidence can be collected by detecting red blood cells and spermatozoa at the scene of a crime. The search for illicit drugs is greatly facilitated by selective spot tests in their preliminary identification. 

This example also shows that the RSCAE can prevent the squandering of money on ineffective safety measures. In Switzerland, which is a small country, the artillery training of the troops cannot be conducted in absolutely isolated shooting ranges. It has to take place in normally utilized and populated areas, not without a number of precautions, of course. Consequently, there are a few hundred duds a year, which normally are blown up immediately by the troops themselves or by special dud-disposal teams of the defense administration. As the duds sometimes cannot be found immediately, especially those in snow, from time to time accidents have occurred resulting in personal injuries or even fatalities. 

A shooting range adjacent to the San Francisco bay placed the targets at the water s edge so that stray bullets fell harmlessly into the bay. Normally shooting ranges recover spent bullets as metal scrap. However, recovery was impractical at the bay because the bullets sank into the muddy bottom, estimated to be 3 m of silt below 10 m of water. The lead content in the water of the bay was recently found to be abnormally high. Initially a nearby chemical plant was blamed, but close examination revealed that the plant effluent contained no lead and that no process at the plant ever involved lead. 

Duck hunters rise to shoot from a hunting blind. Hunters have contributed millions of dollars to conservation in America through a self-imposed excise tax of 10 - 11 percent on sporting goods. This tax, loosely called the Pittman-Roberlson Act, funds wildlife habitat restoration, hunter education and the development of shooting ranges. (Photo Dr. F Eugene Hester, U S FWS)...

Big guns like this Barrett 50 caliber make a serious noise and, in the hands of a skilled marksman, can kill at more than a mile. Few shooting ranges in the eastern half of the U.S. can handle such a rifle, and traditional bullet fragmentation or dispersion following impact would be a true problem if the guns and their ammo weren t so expensive. 

It is apparent, although the letter and opinions are 15 years old, that the science did not then - and does not now - support a necessity to ban lead ammo from shooting ranges and that Dr. Proctor, who was one of only two board certified toxicologists in ffouston, was willing to testify to that fact.
