Fish from American Waters are Contaminated with Mercury
21 August 2009 | Green News | 1 Comment
Recently, American Geological Services announced, after several studies, that all freshwater-fish from United States, contain a neurotoxic substance…mercury!!!Some studies made by US Geological Survey shows that 292 rivers and lakes in United States are full of fish contaminated with mercury.
Air Pollution Could Decrease Newly Born Childrens IQ

Pollution of air, water, soil and many other natural elements, have as side effects destruction of plant and animal habitats,leading to the disappearance of plant and animal populations and also can affect human organism. Air pollution can affect respiratory system, water pollution and soil can affect digestion and other similar processes. Recently, a study made by researchers from NIEHS (National Institute of Environmental Health Sciences) shows that human IQ can be also affected by athmospheric pollution(eg, mothers exposed to any kind of pollution could born children with a low IQ).
The Coca-Cola Company to get more environmental-friendly
12 June 2009 | Green Technology | 2 Comments
As a consequence of being the world’s largest beverage company, Coca-Cola also holds the record for world’s biggest PET plastic bottles producer. It is known that this polyethylene terephthalate or PET plastic bottles are non-renewable. Less known is that Antimony triacetate is being used in the production of PET plastic which remains in the material and can, in principle migrate out into food and drinks. Although antimony trioxide is of low toxicity, its presence is still of concern to the health.

Electromagnetic People Killer – Mobile Phone
4 May 2009 | Green Technology | 1 Comment
Mobile phones, called also cellular phones, are an integrating part of modern telecommunications, which offer the possibility of maintaining the continual communication without affecting the movement liberty.In many countries, more than half of the population uses mobile phones and the market develops fast.The prognosis shows that in 2009 will be, in the entire world, 1,9 bilion of surscribers of the mobile telephony services.Because of this reason it was necessary the installation of an increased number of basis station.The basis stations are radio antennas of low power that communicate with the users apparatus.At the beginning of 2000, they were about 2000 basis stations functioning in Great Britain and about 82.000 locations destined to the cellular telephony in the United States, each location including one or more basis stations.
On the pollution effects due to the mobile telephones were made numerous studies, the results of recent studies regarding the effects of the exposure to the electromagnetic fields of radio frequency (RF) on human beings are supplied by the World Health Organization, the Royal Society of Canada and by a committee of experts in Great Britain.
The RF fields get in the tissues exposed to depths that depend on frequency – until 1 cm at the frequencies used by mobile phones.The RF energy is absorbed in the body and produces tissues heating which is dispersed normally through the thermo adjustment mechanism of the body.All the proved effects of the exposure to RF are clearly connected to the heating.While the RF energy can interact with alive tissues at low levels to produce a significant heating, none of the studies did not put into evidence the unwanted effects on health at exposure levels under the authorized limits through international directives.
More studies on animals exposed to the RF fields similar to these emitted by the mobile phones have not found any proof that RF produce or favor brain tumors.While a study made in 1997 revealed the increase of the rate at which the lymphomas were developed at the mice genetically modified, the implications of this result on health are still ambiguous.Nowadays there are running more studies to confirm this observation and to determine any revelance to human cancer.Three epidemologic recent studies have not found any convincing proof of the increase of cancer risk or any other disease along with the use of the mobile phones.
