静磁场对健康的潜在影响受到的关注要少得多。例如，电源频率或射频场。静态场存在于某些职业环境中，例如在铝和氯碱工业、电弧焊接工艺以及某些铁路系统中。用于医学诊断的磁共振成像（MRI）是另一个来源。本文总结了静磁场暴露和长期健康影响的流行病学证据。目前只有少数流行病学研究，其中大多数都集中在癌症风险上。有一些关于生殖结果的报告，以及其他结果的零星研究。全面的。很少有职业研究专门关注静磁场暴露的影响。因此，暴露评估很差或根本不存在。估计静磁场暴露的研究结果并未表明癌症风险有任何增加，但它们通常基于少量病例和粗略的暴露评估。对混杂因素的控制有限，“健康工人”效应很可能影响了结果。一些研究报告了铝工人和核磁共振操作员生殖结果的结果，但研究设计的局限性阻碍了结论。静磁场流行病学研究的一个问题是，从事暴露职业的工人也暴露于各种其他潜在有害物质。包括一些已知的致癌物质。总之，流行病学研究的现有证据不足以得出有关静磁场暴露的潜在健康影响的任何结论。 (C) 2004 Elsevier Ltd. 保留所有权利。
Potential health effects of static magnetic fields have received far less attention than. for example, power frequency or radiofrequency fields. Static fields are found in certain occupational settings, e.g. in the aluminium and chloralkali industries, in arc-welding processes.. and certain railways systems. Magnetic resonance imaging (MRI) for medical diagnosis is another source. This paper summarizes the epidemiological evidence of static magnetic field exposure and long-term health effects. There are only, a few epidemiological studies available, and the majority of these have focused on cancer risks. There are some reports on reproductive outcomes, and sporadic studies of other outcomes. Overall. few occupational studies have focused specifically on effects of static magnetic field exposure. and exposure assessment have consequently been poor or non-existent. Results from studies that have estimated static magnetic field exposure have not indicated any increased cancer risks, but they are generally based on small numbers of cases and crude exposure assessment. Control of confounding has been limited, and it is likely that the "healthy worker" effect have influenced the results. A few studies have reported results on reproductive outcomes among aluminium workers and MRI operators, but limitations in study designs prevent conclusions. A problem in epidemiological studies of static magnetic fields is that workers in exposed occupations are also exposed to a wide variety of other potentially harmful agents. including some known carcinogens. In conclusion, the available evidence from epidemiological studies is not sufficient to draw any conclusions about potential health effects of static magnetic field exposure. (C) 2004 Elsevier Ltd.
