| November 24, 2010 | Wi-Fi radiation found harmful to trees; What about human beings? | | London: Wi-fi networks that enable our burgeoning online communications are a threat to trees, say Dutch scientists. According to the study in Holland, trees
planted close to a wireless router had bleeding bark and dying leaves, reports the Daily Mail. The revelation has raised fears that wi-fi radiation may also
be having an effect on the human body. The city of Alphen aan den Rijn, in the
Netherlands, ordered the study after officials found unexplained abnormalities
on trees. Researchers took 20 ash trees and for three months exposed them to six
sources of radiation. Trees placed closest to the wi-fi source developed a 'lead-like
shine' on their leaves that was caused by the upper and lower epidermis - the
leaf's skin - dying. Researchers also discovered that wi-fi radiation could slow
the growth of corn cobs. In the Netherlands, 70 per cent of all trees in urban
areas show the same symptoms, compared with 10 per cent five years ago, the study
found. The Wageningen University scientists, who conducted the study, said that
further studies were needed to confirm their findings. The Dutch health agency
issued a statement, stressing that "these are initial results and that they have
not been confirmed in a repeat survey". It added: "There are no far-reaching conclusions
from its results. Based on the information now available it cannot be concluded
that the wi-fi radio signals leads to damage to trees or other plants."
