Although it is well known that both cigarette smoke and microscopic airborne asbestos fibres can cause lung cancer, evidence as to how these two agents combine is nebulous. Many workers have believed in the multiplicative theory, whereby as...
Performance of power assisted respirators during simulated asbestos removal [0.03%]
动力呼吸器在模拟石棉清除过程中的性能表现

M P Clayton et al.
Protection factors were measured on full face mask power assisted respirators when worn by experienced asbestos removal operatives under simulated asbestos removal work conditions. The sulfur hexafluoride test method as defined in European ...
Control of exposure to hexavalent chromium and ozone in gas metal arc welding of stainless steels by use of a secondary shield gas [0.03%]
二次屏蔽气体在不锈钢气体金属电弧焊中控制六价铬和臭氧暴露的研究
John H Dennis,Michael J French,Peter J Hewitt et al.
John H Dennis et al.
Previous work has demonstrated that the shield gas composition in gas metal arc welding can have a considerable effect on hexavalent chromium [Cr(VI)] concentration in the fume and on ozone concentrations near the arc. Normally a single shi...
Control of occupational exposure to hexavalent chromium and ozone in tubular wire arc-welding processes by replacement of potassium by lithium or by addition of zinc [0.03%]
通过用锂或添加锌替代钾来控制管状药芯焊丝焊接过程中六价铬和臭氧的 Occupational Exposure Limit 超标现象
John H Dennis,Michael J French,Peter J Hewitt et al.
John H Dennis et al.
Hexavalent chromium [Cr(VI)] and ozone are produced in many arc-welding processes. Cr(VI) is formed when welding with chromium-containing alloys and is a suspected carcinogen. Ozone is formed by the action of ultraviolet light from the arc ...

Following the classification of quartz as a human carcinogen by the IARC, many standard-setting committees are currently trying to convert this hazard into their national or EU standards. Since human data to set a safe exposure limit for qu...
Seasonal variations in injury rates during US Army Basic Combat Training [0.03%]
美国陆军基础战斗训练中伤员的季节性变化规律

Joseph J Knapik et al.
Objectives: Previous literature suggests that injury rates during physical activity may be higher in the summer than in the fall or winter, possibly due to the greater amount or intensity of physical activity in the summe...
