A possible effect of long-term exposure to low-intensity electromagnetic radiation from mobile phone (GSM) base stations on the number of House Sparrows during the breeding season was studied in six residential districts in Belgium. We sampled 150 point locations within the 6 areas to examine small-scale geographic variation in the number of House Sparrow males and the strength of electromagnetic radiation from base stations. Spatial variation in the number of House Sparrow males was negatively and highly significantly related to the strength of electric fields from both the 900 and 1800 MHz downlink frequency bands and from the sum of these bands (Chi(2)-tests and AIC-criteria, P<0.001). This negative relationship was highly similar within each of the six study areas, despite differences among areas in both the number of birds and radiation levels. Thus, our data show that fewer House Sparrow males were seen at locations with relatively high electric field strength values of GSM base stations and therefore support the notion that long-term exposure to higher levels of radiation negatively affects the abundance or behavior of House Sparrows in the wild.
在比利时的六个居民区，研究了繁殖季节长期暴露于手机（GSM）基站低强度电磁辐射对家麻雀数量的可能影响。我们在这6个区域内对150个点位进行了采样，以研究家麻雀雄鸟数量的小尺度地理变异以及基站电磁辐射强度。家麻雀雄鸟数量的空间变异与900和1800 MHz下行频段的电场强度以及这些频段总和呈高度显著的负相关（卡方检验和AIC准则，P<0.001）。尽管各区域鸟类数量和辐射水平存在差异，但在六个研究区域中的每一个区域内，这种负相关都非常相似。因此，我们的数据表明，在GSM基站电场强度相对较高的地点看到的家麻雀雄鸟较少，从而支持了长期暴露于较高水平辐射会对野生家麻雀的数量或行为产生负面影响这一观点。
