Brazilian Courts Order Lower Power Line Electromagnetic Pollution
The Court of the State of Sao Paulo recently determined that the Sao Paulo electricity transmission provider must reduce the level of electromagnetic (EMF) pollution produced by power lines to standards adopted by Swiss law (1.0 microtesla or 10 mG) (Environmental News Network). Currently, EMFs generated by overhead transmission lines in Sao Paulo, and most other places around the world, are at least 10 times higher than this near the lines. (For example, the EMF levels are about 12 to 14 times higher than 10 mG near transmission lines in the Edmonton, Alberta area.)
The court decision was based on the Brazilian Federal Constitution and the United Nations Precautionary Principle, which both declare the protection of health and the environment. The court also widely examined the international research on the effects of EMFs on health, and recognized “the great possibility of the electromagnetic field of low frequency to be a carcinogenic agent in human beings”.
