In this study, the daily exposure action values (EAV) and the daily exposure limit values (ELV) for hand-transmitted vibration (HTV) and whole-body vibration (WBV), established by the EU Directive 2002/44/EC and the Italian Decree 81/2008, and expressed in terms of 8-hr frequency weighted r.m.s. acceleration magnitude, are discussed upon consideration of the findings of experimental and epidemiological studies.
There is some epidemiological support for the EAV A(8) of 2.5 ms-2 r.m.s. and the ELV A(8) of 5 ms-2 r.m.s. for HTV, at least for the vascular component (secondary Raynaud's phenomenon) of the hand-arm vibration syndrome.
There is some experimental evidence for the EAV A(8) of 0.5 ms-2 r.m.s. for WBV, while there is neither biodynamic nor epidemiological validation for the ELV A(8) of 1.15 ms-2 r.m.s. for WBV, this latter lowered to 1 ms-2 r.m.s. in the Italian legislation.
在本研究中，考虑到实验和流行病学研究结果，对欧盟指令2002/44/EC和意大利法令81/2008所确立的、以8小时频率加权均方根加速度幅值表示的手传振动（HTV）和全身振动（WBV）的每日暴露行动值（EAV）和每日暴露限值（ELV）进行了讨论。
对于HTV，至少就手臂振动综合征的血管成分（继发性雷诺现象）而言，有一些流行病学证据支持其EAV A(8)为2.5 ms-2均方根和ELV A(8)为5 ms-2均方根。
有一些实验证据支持WBV的EAV A(8)为0.5 ms-2均方根，而对于WBV的ELV A(8)为1.15 ms-2均方根，既没有生物动力学验证也没有流行病学验证，在意大利立法中该值降至1 ms-2均方根。
