Abstract:
Since 2005, on the occasion of medical examinations of sick residents living near mobile phone base stations, changes in nearby trees (crown, leaves, trunk, branches, growth) were observed at the same time as clinical symptoms in humans occurred. Both deciduous and coniferous trees as well as shrub species were affected. The assessment of tree diseases is neither impeded by psychological impacts nor by change of location.
Impacts of radiofrequency electromagnetic fields (RF-EMF) from radar, radio and TV on plant life have been scientifically demonstrated over the past 80 years. Since 2005, the influence of modulated RF-EMF that are used in mobile phone telephony - has been investigated in lab experiments. Several research groups reported about the impacts on germination, growth and cell metabolism. Only a few scientific papers have been published to date on research concerning the health conditions of trees in the vicinity of mobile phone base stations. These papers are indicating harmful impacts.
For this reason, between 2007 and 2013, the status of trees standing in the neighbourhood of 620 mobile phone base stations was documented. In the radio shadow of buildings or that one of other trees, the trees stayed healthy. However, within the radiation field, damages were observed on exposed trees. Additionally, unilateral crown damage, beginning on the side facing the antenna, strongly indicates a causal relationship with RF-EMF. In the following, examples of crown damages and of premature colouring of leaves are presented. The authors believe, that scientific research is urgently needed to examine these observations.
