“…Experiments on patients with diseases of the respiratory tract (asthma, hay-fever) showed that negative ions in general had a beneficial influence whereas the positive ions had no, or a detrimental effect. The literature concerning atmospheric ions, electro-aerosols and physical medicine has been reviewed by Wehner (8), Knoll et al, (6) and Andersen (1), Most of the publications concerning the influence of ions on the respiratory tract are uncontrolled, the reproducibihty of the results are poor, and have not been confirmed by others (2,9), All doctors working with patients with bronchial asthma know the great placebo effect connected with introduction of a new therapy. This study was carried out as a controlled blind study with one of the authors (O,A,) helping the medical staff change the ion conditions.…”

“…Patients with bronchial asthma suffer from a general hyperreactivity in the airways to a number of stimuli in the inhaled air such as pollen, dust, fumes, cigarette smoke, and changes in the weather. Atmospheric ions are often claimed to interfere with asthmatic disease, but very few controlled studies concerning the influence of ions on bronchial asthma have been carried out (2,9), Nevertheless, ion therapy is widely used throughout the world and ion generators for home treatment are available although we still do not know whether they have any influence on the airways.…”

The influence of artificially generated atmospheric ions is studied in 15 patients with bronchial asthma. A slight but significant (at 5% level) improvement in the lung function was demonstrated in nine patients during positive as well as negative ion exposure, but the patients' subjective votings of the air quality did not show any changes due to ion exposure. No change in the histamine threshold of the airways in six patients with bronchial asthma was demonstrated during exposure to ions. Further controlled studies with electro-aerosols are needed.

“…Based upon this hypothesis and some animal studies, a number of investigators have evaluated the ability of air ion exposures to improve pulmonary function. However, quantitative experimental studies and a double-blind clinical study do not support this hypothesis (Zylberberg and Loveless, 1960;Lefcoe, 1963;Blumstein et al, 1964;Mottley and Yanda, 1966;Albrechtson et al, 1978).…”

DISCLAIMER IntroductionEnvironmental issues are addressed in the permitting process of every transmission line project, whether it be a new line or an upgrade of an existing line. In recent years, the most controversial issue associated with alternating current lines is the potential effects of electromagnetic fields on human health. However, environmental effects on animals, plant life and other electrical and communication systems also must be assessed in every case. Although different from ac lines, high voltage direct current (HVDC) lines also produce environmental effects that warrant review and assessment in every project. This report strives to define the various environmental effects associated with HVDC lines, discusses the current knowledge of their potential effects on biological and non-biological systems, and compares these effects associated with ac lines where appropriate. The Environment Near an Electric Power LineThe electrical environment of a high voltage transmission line can be characterized by three electrical parameters: 1) the electric field, 2) the air ion and charged aerosol concentration, and 3) the magnetic field. The electric field arises from both the electric charge on the conductors and for an HVDC transmission l i e , charges on air ions and aerosols surrounding the conductor.In addition, corona may also produce low levels of ozone, audible noise, electric field and radio interference. A magnetic field is produced by current flowing through the conductors. Summary of Key FindingsIons. Neither the animal nor human studies provide any reliable evidence for the proposition that air ions produce any harmful effects. In fact, there is considerable uncertainty as to whether there are any biological responses to air ions. At the levels produced by HVDC transmission lines, the possibility of risk to human health appears remote, if not vanishingly small. There are no published guidelines for maximum ex...

The purpose of this double-blind, randomised, placebo-controlled cross-over study was to evaluate whether corona ionisers placed in bedrooms could improve nocturnal asthma and other symptoms in asthmatics which might be related to the indoor climate. Active or inactive (placebo) ionisers were placed in the bedrooms of 15 patients for two subsequent 4-week periods. The patients recorded daily/nightly symptoms, medication and peak expiratory flow. A histamine challenge was performed initially and after each period to measure the effect on hyperresponsiveness. Statistical analysis showed no significant differences between active and placebo periods with regard to lung function, medication, nocturnal asthma or other symptoms supposed to be related to indoor climate.
