Veel elektririistade mõjust tervisele

Vahendasin mõni aeg tagasi Briti ajalehe The Independent artiklit, et ilmumisel on uuring, mis siduvat elektriseadmed teatud terviseohtudega.

Eelmises loos avaldasin kahtlust selle üle, et miks oli ajakirjanik sisse toonud hetkel poliitiliselt kuuma teema seoses wifi ja mobiilimastidega, kuigi uuringu pressiteates selles suunas ei viidata.

Nüüd teame paremini.

The effects of electric fields on charged molecules and particles in individual microenvironments

Abstract
Measurements of small air ion concentrations, electrostatic potential and AC electric field strengths were taken in an office setting to investigate the link between electric fields and charged molecule and particle concentrations in individual microenvironments. The results obtained indicate that the electromagnetic environments individuals can be exposed to whilst indoors can often bear little resemblance to those experienced outdoors in nature, and that many individuals may spend large periods of their time in ‘‘Faraday cage’’-like conditions exposed to inappropriate levels and types of electric fields that can reduce localised concentrations of biologically essential and microbiocidal small air ions. Such conditions may escalate their risk of infection from airborne contaminants, including microbes, whilst increasing localised surface contamination. The degree of ‘‘electro-pollution’’ that individuals are exposed to was shown to be influenced by the type of microenvironment they occupy, with it being possible for very different types of microenvironment to exist within the same room.

It is suggested that adopting suitable electromagnetic hygiene/productivity guidelines that seek to replicate the beneficial effects created by natural environments may greatly mitigate such problems.

Ka David Colquhoun kirjutab oma uues teadusalases blogis, et ajakirjanik on teemast mööda rääkinud, kuid oma osa desinformeerimises on ka uuringu teinud ülikooli pressiosakonnal.

* Uuringus ei ole tehtud ühtegi tervisealast mõõtmist
* Uuringu tulemustel ei ole mitte mingisugust pistmist wifi- ja mobiiliseadmetega
* Mõõdeti väikeste õhuioonide (SAI) kontsentratsiooni, elektrostaatilist potentsiaali ja vahelduvvoolu välja tugevust

Seosed tervisega on väga spekulatiivsed, kuna selliseid mõõtmisi pole tehtud.
