Anyone can get lead poisoning; however, the risk to children under seven years old is the highest. The chemical analysis consists of measuring seven trace elements--arsenic, antimony, tin, copper, bismuth, silver, and cadmium-that typically are present in a bullet's lead alloy.
A general recommendation is that the temperature be held constant in the range of 21-23Â°C (69-73Â°F). In summertime when outdoor temperatures are higher it is advisable to keep air-conditioned offices slightly warmer to minimize the temperature discrepancy between indoors and outdoors.
If we look at the research that gives us 71.5 degrees F as the optimal temperature and 100% productivity we only go down in productivity as temperature increases or decreases. As temperature increases: 1  at 77 degrees F we're about 98% productive. 2  82 degrees F = 95%.3  87 degrees F = 90%. 4  92 degrees F = 85%.t may seem like common since that the working at a comfortable temperature would make you more productive, but what may not be apparent is how much of a difference just a couple of degrees can make in that very same productivity and your overall office ergonomics.
