低频电磁场生态效应低频电磁场生态效应biological effects of low-frequency electric and magnetic fields来衡t磁场强度的商低，得出了承受较强工频磁场的长期作用的儿童患白血病的危险率是对照组儿童的3倍的结论.由于这份报告，引起了各国对工频磁场生态形响的关注。但是.随后美国电力科学院的研究表明，根据对住宅内磁场强度的实测，儿童患白血病的危险率仅是对照组的1.2倍，两者在统计学上无显著性差异。1982年，美国邦纳维尔电力管理局(BPA)公布的研究结果表明:翰电线下距地面lm处的磁感应强度通常不超过。.o35mT，而家用电器附近，例如厨房内的工叔磁场可达约0.5~lmT，远远高于输电线下的磁场强度。然而，由于愉配电系统电磁场的生态效应是一个极其敏感的间题。有些地区公众心存疑虑，对翰电线路建设采取抵制的行动，以至新建翰电线路十分困难。因此，弄清电磁场的生态影响，一直是国内外的一个研究热点。不少国家正在通过流行病学研究、动物实验、分子生物学研究等途径.一直在进行大量的研究.由于电磁场与生物系统的相互作用的机理十分复杂，短期内难以得出明确结论。研究的进展主要反映在流行病学研究、动物试脸研究以及电磁场生态影响的机理研究三个领域取得的进展。流行病学研究的进展用流行病学的方法研究电截场的生态影响是最常用的研究方法.即对经常处在较强电磁场作用下的职业人群的健康状况与对照组进行统计分析比较.从1979年后数年间，发表了10份对住宅内电磁场强度与痛症发病率是否相关的研究报告。有4份报告发现有一定的相关关系，而6份报告没有发现有相关关系。研究结论的不一致主要是由于研究方法本身的缺陷产生的，即流行病学方法很难排除其他致病因素(如环境污染、抽烟等)的影响.由于不可能找到与研究对象完全相同的对照组人群。很难说明患某种疾病的原因是由电磁场的作用还是由其他原因引起。研究结论不一致的另一个原因是衡量电磁场强度的方法不同。现在专家普追认为，应当采用随身携带的磁场计作长期的积累侧量才能得出比较可信的结果。动物试验研究的进展在实验室中，用基礴于可调节的磁场的实验动物作为研究对象与对照组进行对比，是另一重要的研究方法。迄今为止，大多数专家认为可信的实验数据表明，磁场不会直接损伤细胞的基因，因而不会导致痛症。电磁场生态影响的机理研究有专家提出一种假设，即磁场会影响人体的内分泌系统，从而间接导致某种疾病，如乳腺痛。有些研究报告报导，过量的低频磁场会使人体分泌的松果体素(melatonine)受到抑制(松果体素是人的脑垂体分泌的调节生物节律的激素)。
