人们对使用手机一直存在一个争论:长时间使用手机是否会对健康产生不利影响?
最近,法国科学家通过试验分析了手机辐射对鸡蛋孵化的影响,从另一个角度回答了这个问题。相关报道发表在2008年2月的爱思唯尔期刊《动物生殖学》(Theriogenology)在线版上。
研究人员使用一部手机每隔3分钟拨打一次电话,受精鸡蛋在整个孵化期内都暴露在这部手机的辐射下。同时,试验中还有两个对照组,其中一个对照组的孵化环境中没有手机辐射;另一个对照组的孵化环境中有一部手机,但没有拨打和接听。
试验结果表明,将受精鸡蛋暴露在手机辐射下将对孵化产生明显的不良影响。暴露在持续拨打的手机辐射下的实验组胚胎死亡率高达64%,这比其它两个对照组的平均11%的死亡率高出很多。GSM移动电话对胚胎发育的致命作用主要发生在孵化的第9至12天,正常发育鸡胚胎的羽毛、喙和眼帘都是在这几天里形成的。
研究人员同时指出,相对来说,暴露在手机辐射下的鸡蛋的孵化条件要差一些,主要是因为实验条件的限制导致孵化人员在孵化初期不能经常翻动这些鸡蛋。尽管如此,该研究还是清楚地表明,长期受手机辐射导致鸡蛋胚胎发育失败。这与此前的一些研究成果是一致的。(科学网 荔涛/编译)

Abstract
The aim of the present study was to assess the effects of exposing fertile chicken eggs to a cell phone repeatedly calling a ten-digit number at 3-min intervals over the entire period of incubation. A pre-experiment was performed first to adjust incubation conditions in an experimental chamber devoid of metallic content and without automatic turning until the overall performance of hatchability was reproducible in the absence of the cell phone. The experimental period consisted of a series of 4 incubations referred to as “replicates”. For each replicate, one batch of 60 eggs was exposed to the immediate environment (≤25 cm) of a cell phone in the “call” position (exposed group), while another batch of 60 eggs, 1.5 m away from the exposed group and also in the incubation chamber, was exposed to a similar cell phone in the “off” position (sham group). For each replicate, 2 other groups each of 60 eggs were also incubated, one in a standard mini-incubator (“Control I” group) and the second in a standard medium size incubator (“Control II” group). Temperature, relative humidity and electromagnetic fields in the experimental chamber were permanently monitored over the entire experiment. A significantly higher percentage of embryo mortality was observed in the “exposed” compared to the “sham” group in 2 of the 4 replicates (p < .05). In comparison with control groups, additional embryo mortality in the exposed group occurred mainly between Days 9 and 12 of incubation but a causal relationship between the intensity of the electric field and embryo mortality could not be established.
