Re AMA Position Statement: Wind Farms and Health

1. I am a Canadian citizen, formerly a dean of medicine, assistant deputy minister of health federally and a practising orthopaedist. I am a founding member of the Canadian Institutes of Health Research funded Evidence Network.

2. I have engaged with over 100 exposed individuals residing near industrial wind developments in the province of Ontario. These cases are documented [1].

3. I have appeared as an expert witness on behalf of plaintiffs in actions versus the erection of wind farms too proximate to human habitation.

4. I am writing to comment on the AMA Position Statement. The position statement is surprising. It is not well informed, references are absent and the authors of the document are undisclosed. Many of the phrases and claims in the document faithfully reflect wind industry claims, claims which cannot be substantiated.

5. Review of the existing evidence in which direct assessment of exposed individuals has been carried out uniformly reveals adverse health effects [2]. The common denominator of complaints consists of sleep disturbance, inner ear disturbance and stress response. These are serious adverse health effects. These adverse health events have been reported globally in the media and grey literature.

6. I concur with that part of the AMA document that asserts that siting of wind farms “should be guided by the evidence”. Unfortunately the remainder of the AMA document fails to meet that standard.

7. I challenge the AMA to support third party research that leads to simultaneous physiological monitoring of exposed individuals during sleep and concurrent recording of sound pressure levels (SPL) including all frequencies (infrasound and low frequency sound) as well as weighted and unweighted decibel or sound intensity levels in the bedroom and outside the home. [Note averaging of SPL should not be done exclusively since key characteristics of the noise such as cresting and amplitude modulation will be excluded.]

8. In the absence of the information outlined in #7 above there has not been nor can there be evidence–based guidelines for the siting of wind turbines. This fact ought to concern the AMA and all responsible physicians.

9. More details are available upon request.
