Summary of recent observations of adverse health effects from wind developments  

Author:  | Australia, Health, Human rights

Recent field observations

  • Ongoing data collection from multiple Wind Developments across SE Australia
  • Includes information from following sources:
    • interviews with affected residents
    • medical records
    • treating physicians
    • personal health journals
    • acoustic monitoring inside homes

Summary of key findings

  • Over 60 people interviewed so far
  • Includes local residents, workers and visitors
  • Symptoms characteristic of exposure to wind turbines (never previously experienced) noted up to 10km away
    • Night time waking in panicked state
    • Body vibrations
  • Symptoms ALWAYS worsen with increasing exposure over time
  • Consistent with previous findings of Medical practitioners such as
    • Dr Amanda Harry (UK Rural Family Physician)
    • Dr David Iser (Australian Rural Family Physician)
    • Dr Nina Pierpont (US Paediatrician)
    • Dr Robert McMurtry in the Society for Wind Vigilance community health survey
  • Many symptoms were known to, and reported by Acousticians such as Dr Leventhall, prior to 2004, in situations of known infrasound & low frequency noise (ILFN) exposure (Report for DEFRA by Dr G Leventhall, Dr P Pelmear & Dr S Benton May 2003, “A review of Published Research on Low Frequency noise and its Effects”)
  • Symptoms start to resolve when
    • Turbines are off (especially if more than 24 hours)
    • People move away from turbines

    BUT

  • People “sensitized” with prolonged exposure then notice symptoms with other sources of ILFN
    • Pumps
    • Heating & Cooling compressors/ventilation systems

Health problems identified

  • Preexisting medical conditions which worsen with wind turbine exposure
    • Hypertension (high blood pressure)
    • Angina
    • Diabetes
    • Tinnitus
    • Migraines
  • Severe Chronic Sleep Deprivation (multiple causes which include)
    • Audible turbine noise
    • Waking in a panicked state, wide awake, sometimes on multiple occasions every night
    • Increased nocturnal urination
    • Children’s sleep problems
    • Bed vibrating
  • Severe Frequent Headaches
    • Head “in a vice”
    • Children with no previous history of headaches
    • Migraines triggered, especially from shadow flicker
    • Visual Blurring
      • Only occurring with turbine operation
      • Visual checks by health practitioners normal
    • Tinnitus (ringing or buzzing, one or both ears)
    • Ear pressure sensations (painful at times, especially if previous eardrum surgery)
    • Hyperacusis (extreme sensitivity to ‘normal’ sounds)
    • Balance disturbance (especially in elderly)
    • Motion sickness/vertigo like symptoms
    • Nausea (severe)
    • Irritability, extreme anger and other mood disturbances (also being reported in workers)
    • Memory & Cognitive deficits (worsening over time)
    • Depression, at times life threatening
    • Anxiety
    • Body vibrations
    • Tachycardias & arrhythmias (fast & irregular heartbeats)

    Additional clinical observations

    • Reports emerging of two specific clinical illnesses known to be caused by surges of adrenaline occurring with exposure to wind turbines (and other sources of ILFN)
      • Tako Tsubo heart attacks
      • Acute Hypertensive Crises
    • Limited animal studies confirm infrasound exposure can result in adrenaline surges (NIEHS Toxicology of Infrasound report 2001)
    • ILFN induced Sympathetic nervous system stimulation, via Vestibular stimulation or direct stimulation of the brain, is experienced ACUTELY by the person affected as:
      • Tachycardia (fast heart beat)
      • Elevated blood pressure including acute hypertensive episodes
      • Tako Tsubo heart attack episodes
      • Nighttime waking in a panicked state
      • Acutely anxious feelings
      • Unmasking of previous PTSD symptoms (but either well controlled or in abeyance at time of initial exposure to wind turbines)
    • Observations of new onset hypertension (high blood pressure) with turbine operation
    • Multiple causative mechanisms likely, probably concurrent (Qibai and Shi (2007) The Effects of Low Frequency Noise and Vibration on People [ed Prof C. Hansen] An Investigation on the Physiological and Psychological Effects of Infrasound on Persons 303-310)
      • Infrasound (experimental studies have shown this effect, via direct or indirect (vestibular) stimulation of sympathetic nervous system ‘fight–flight’)
      • Stress
      • Sleep Deprivation

    Predictors of onset & severity
    Predictors of Rapid Onset of Severe Symptoms of Wind turbine Syndrome (WTS) appear to be

    • Living downwind of a line of turbines (cumulative impact)
    • Presence of ground borne (seismic) vibrations
      • Beds vibrating
      • Glass of water vibrating

    Other reports of residential overnight exposure to ILFN

    • Overnight exposure to ILFN seems particularly damaging to health
    • Others who have developed similar health problems including Tako Tsubo Heart attacks, sleep deprivation and high blood pressure which start to partially resolve when exposure ceases
      • Residents in suburban Melbourne next to industrial chillers at Melbourne University
      • Residents 5km away from open cut coal mining activities active at night (diesel machinery)

    Links to vibro acoustic disease

    • Substantial body of work by Professor Mariana Alves Pereira & Dr Nuno Castelo Branco over 30 years in Portugal
    • Serious health concerns (VAD) with chronic exposure to ILFN (variety of sources)
    • Based on their recent work, levels of measured ILFN inside homes near wind developments will result in VAD in residents

    Tissue vibro acoustic diseaserved in VAD

    • Thickened collagen, resulting in
      • Decreased lumen of blood vessels (arteries)
      • Thickening of exterior lining of the heart (pericardium)
    • Malignant tumours in the sole autopsy case
      • (patients with WTS have been noted to have elevated cortisol which will certainly decrease the body’s own immunity and ability of the immune system to eradicate abnormal cells over time)
    • Professor Alves Pereira also described collagen pathology found in horses on the farm in Portugal, using a case control design
      • Ie, collagen changes are “cross species”, adding further weight to the evidence of a biological causal effect of ILFN on tissue with chronic exposure

    The relationship between WTS & VAD

    • I think Dr Pierpont is right, in stating as she did in Ontario that maybe we should call WTS “ILFN syndrome”
    • Acousticians for years have been calling these symptoms “annoyance” without Medical Clinicians realising that there are serious health problems emerging with acute and chronic exposure (with a few notable exceptions such as Dr Harry, Dr Iser, Dr Pierpont & Dr Castelo Branco)
    • My conclusions
      • There are multiple pathophysiological mechanisms causing the pathology we are seeing
      • There is a difference between the effects and therefore the symptoms of acute exposure (WTS) and chronic exposure (VAD)
      • There may be a synergistic effect eg angina
        • Acute effect – adrenaline surge leading to vasoconstriction
        • Chronic effect – collagen thickening producing structurally narrowed diameter of blood vessel
        • Both pathologies acting together will result in decreased blood flow to the heart muscle

    Mechanisms for harm to health

    • KNOWN – audible noise
    • HIGHLY LIKELY – Infrasound & low frequency noise
      • Airborne pulsations
      • Resonance within dwellings
      • Seismic (ground borne) vibrations
    • POSSIBLE – Electromagnetic radiation effects
    • OTHER?

    What we know already

    • Chronic severe sleep deprivation and high blood pressure are very damaging to health (extensive peer reviewed research)
    • Both are being identified as new health problems in residents adjacent to wind developments after commencement of turbine operation
    • Both are measurable

    These need to be investigated and quantified

    Research questions

    1. What is a ‘safe’ setback distance?
    2. What are the mechanisms of causation?
