All deciduous trees in the western world suffer from. The findings come from a recent study at TU Delft, TNO, Alphen aan den Rijn and Wageningen University. The research was driven by the municipality of Alphen aan den Rijn.   Officials were five years ago against unexplained abnormalities on trees in the city, including bark-like tumor nodules.   There was not a virus or bacterium. Follow-up testing found the disease to occur throughout the western world. In the Netherlands, shows no less than 70 percent of all trees in urban areas the same symptoms. Five years ago, was only 10 percent.   Trees in more densely forested areas are hardly affected.       Ultra fine particles also cause The researchers of the project also have half cause at hand, besides the electromagnetic fields caused by mobile radio telephony and wireless internet. Ultrafine particles may also have to do. That is so small that the organisms in the intrusion. Within the study were twenty notes for three months exposed to radiation sources.   The radiation came from a test facility located in six WiFi access points. When the trees closest to the radiation sources were, the leaves died.   The experiment was done with corn, which showed that the radiation inhibited the growth of corn cobs.   UPDATE 16.22 pm   The Wageningen University has published details of the tests. The report is not (yet) released. "In a climate room notes and various herbaceous plants for three months exposed to 6 radiation sources (APs) at frequencies ranging from 2412 to 2472 MHz and a power of 100 mW EIRP. At 50 cm to 300 cm. Initial observations indicate a negative impact on the health of ash trees.   Leaves near radiation sources showed at the end of the study period 'galena-like effects' that result prove to be the death of the upper and lower epidermis of leaves. The 'galena' is followed by dehydration and death of a portion of the leaf. Experiments with Arabidopsis and maize crops sowing methods on growth and flowering delay as seed cultures compared with cultures in identical climate rooms without radiation exposure.   Based on these first results is an urgent need to proceed to trial repetition over a longer period to determine whether these results consistently occur and whether additional longer-term effects resulting from the tax."     UPDATE Friday, 13:44 hours   TNO shows via a message on his website know that the organization has distanced itself from the conclusion that the radiation from Wi-Fi has a negative effect on the health of plants and trees. The research states that an employee on several occasions during the study participated in discussions and feedback on test setups and measurement results, but the conclusion regarding the relationship between the two cases are not supported by TNO.   That conclusion is entirely borne by the TNO Wageningen University.               Is Wi-Fi Killing American Trees? by Frank Lake November 22, 2010 from Mater-ReadsTooMuch Website   JOPLIN, MISSOURI   Wi-Fi systems are killing trees across America. There may be no way to reverse the damage. A study by Washington University in St. Louis confirms that Wi-Fi radiation causes abnormalities in trees and these abnormalities eventually lead to tree death. Trees that are exposed to the RF (Radio Frequency) technology of Wi-Fi systems are dead within a year of exposure.   The city of Joplin commissioned the study five months ago. They wanted to figure out why their city’s trees were developing weird growths, according to PC World. The study, conducted by Nobel Prize winning Professor Gunnar Hofverberg - the leading Wi-Fi expert in the United States, and a world-renown arborist.   Hofverberg concluded that 95 percent of trees in urban areas will die from Wi-Fi exposure. “We studied tree bark, tree sap, and the various insects that inhabit trees. They were all adversely affected by RF. Botanists and arborists are extremely concerned and feel that this is a national crisis of epic proportions.” Hofverberg recommends banning all Wi-Fi usage within a ten miles radius of any trees. “It’s the only way we can save the trees of America.” The study exposed 900 ash trees to various radiation sources for a period of three months. Trees placed closest to the Wi-Fi radio demonstrated a “lead-like shine” on their leaves caused dying of the upper and lower epidermis of the leaves - and the ultimate death of the trees.   Additionally, he found that Wi-Fi radiation causes squirrels to mate with chipmunks. “Apparently, the RF radiation affects the hypothalamus and the sexual synapses in the squirrel brain,” said Hofverberg. “But the chipmunks seem to be adapting.” Additionally, on the west coast, excessive Wi-Fi usage is causing forest fires. “This seems to match our study,” said Hofverberg. He also feels that Wi-Fi usage may cause hurricanes and definitely contributes significantly to global warming. Hofverberg, who will be living in an ash tree for the next month, will be beginning a study on shrubs in a month. “Big shrubs.” He’ll have results in ninety days.               Do Wi-Fi Signals Kill Trees? by Adam Hadhazy TechNewsDaily Staff Writer November 22, 2010 from CSMonitor Website     No, they don't, a Dutch study finds. A rumor that Wi-Fi signals sicken trees has been circulating the Internet. It's not true, says a Dutch study. It's an Internet rumor that is spreading, appropriately enough, like wildfire: Wi-Fi signals can make trees and other plants sick, causing cracks in their bark and killing off portions of their leaves. The outlandish claim, supposedly based on a Dutch study, cropped up late last week and has since been repeated in countless blog posts.   In response, the Dutch government's Antenna Agency, which provides information on the health effects of electromagnetic fields, has issued a statement urging caution on the unpublished, unverified and otherwise very preliminary findings. As rendered via Google Translate, the Antenna Agency wrote (with a few [sics]): "Based on the information now available can not be concluded that the WiFi radio signals leads to damage to trees or other plants." Wi-Fi signals wirelessly connect computers and other devices to the Internet.   The radio signals are similar to that employed by other, decades-old technologies such as television and cell phones, said Marvin Ziskin, a professor of radiology and medical physics at Temple University. "Stuff like this has been around a long time... there's nothing new about Wi-Fi emissions," said Ziskin. "Scientifically there's no evidence to support that these signals are a cause for concern." Nevertheless, officials in the Dutch municipality of Alphen aan den Rijn tasked a researcher at Wageningen University several years ago to investigate unexplained abnormalities on local trees. According to a write-up on the municipality's website, the work was apparently commissioned with an eye toward the increasing number of sources of electromagnetic radiation in the region, such as cell phone tower masts.   In lab tests, leaves placed for a few months near six radiation sources emitting radio waves in the 2.4 gigahertz range common for Wi-Fi and other wireless communications became discolored and showed a, "metallic luster appearance... followed by desiccation and death of a portion of the leaf," the website said. Other reports have said that corn cobs exposed to such conditions grew more slowly than expected. The Antenna Agency statement suggests that the researcher involved has backed away from the reported findings and has not succeeded in repeating them (pardon the translation): "The researcher from Wageningen University indicates that these are initial results and that has not been confirmed in a repeat survey. He warns strongly that there are no far-reaching conclusions from its results." More than 60 studies have looked into the impact that electromagnetic mobile communications signals might have on plants, according to an initial review by the Antenna Agency.   Some studies did find detrimental effects, though likely as a result of signal intensities being high (and close) enough to cause heat damage – not the situation in real life with disparate sources of Wi-Fi signals.   Overall, the alarm raised by the coverage of the tenuous Dutch findings is not unexpected, Ziskin said, as health issues (primarily in humans and other animals, such as honey bees, not vegetation) have frequently been attributed to wireless radio signals and other low-level radiation.

"Anyone can drum up things like this to be worried about."   Return to Microwave Radiation and Cell Phones Return to The End of The Internet... As We Know It?
