Your source for health relevant data on your specific indoor environment.


 We specialise in evaluating your home for the most toxic and yet often overlooked health threats in your environment.

Tackle the big 3 threats by knowing what you are exposed to. 

Prevent health degradation and suffering by removing sources of toxicity before they take their toll: contact us for a home toxicity consultation today.


Indoor Chemical Threats

Chemical threats in the home, office, car and pool/spa are widespread. Volatile Organic Compounds (VOCs) are paramount within this category.

One of these VOCs, the known (WHO IARC 2A classified carcinogen formaldehyde, is an unwanted intruder that is of key prevalence in the home environment. It can be found in carpets, paint, flooring, furnishings, domestic products and even electronic consumer products.

Biological Threats

Mould (US “Mold”) is becoming a paramount concern for householders and officeworkers that face the threat of this ubiquitous life form, that breeds whenever there is adequate dampness or humidity and a food source. Fortunately for Fungi, our buildings tend to be made out of food sources for them. It’s not so good for us, though.

Dust mites, mosquito vector borne illnesses, pollen and insect/animal dander can also be seen as part of this category.

Electromagnetic Radiation

Electromagnetic Radiation comes from a wide array of sources in this age of modern electronic wireless devices.

Such artificial radiation is often non-ionising and non-thermal, but nevertheless represents potential harm. It has been permitted into our society under the erroneous assumption that non-thermal levels of RF are harmless.

There is copious evidence in the scientific literature demonstrating at cellular, organ function and systemic levels, that EMR can interfere with normal biological functioning.

“There is increasing and accelerating evidence that synthetic chemicals commonly found in the home contribute to disease and disability.”

The EPA’s framework for evaluating toxicity is “over-simplified and “limited on a number of levels.”

“We’re recognizing that low-level exposure to an array of synthetic chemicals commonly used in our household products contributes to these diseases,” says Trasande. “What little we know suggests broad consequences.”

Fungi harms us by triggering allergic reactions, causing either localized or systemic infections, and exposing us to poisonous waste products called mycotoxins, which have been shown to depress immune function (and have been linked to certain types of cancers) and promote inflammation (associated with heart disease). Lifelong exposure to fungi leaves the body vulnerable to disease. There’s growing evidence based on research in the US (at the Mayo Clinic) and around the world linking fungi to many ailments, including;

  • Eczema, psoriasis and other skin conditions
  • Upper-respiratory tract symptoms
  • Chronic sinusitis
  • Kidney and bladder diseases
  • Parkinson’s disease
  • Dementia and Alzheimer’s disease
  • Cancer of the liver
  • Tumors of the kidneys, urinary tract and colon
  • Endocarditis (inflammation of the heart lining and valves)
  • Atherosclerosis
  • Diabetes and hypoglycemia
  • Hormone imbalance
  • Weight gain
  • Kidney stones

There is considerable evidence and research from various scientific experts that exposure to microwave radiation from wireless devices; Wi-Fi, smart meters and cell towers can have an adverse impact on human physiological function. Many recent and emerging studies from university departments and scientific sources throughout the world support the assertion that energy from wireless devices may be causatively linked to various health problems including reproductive compromise, developmental impacts, hormonal dysregulation and cancer. In fact, in 2011 the World Health Organization listed microwave radiation as a Class 2B possible carcinogen and subsequent research strengthened the evidence that a stronger designation may be justified.


(There are literally dozens of such declarations, statements, committees, resolutions and so forth that have been issued by concerned scientists, medical practitioners and other professionals over the years. For a non-exhaustive listing of some of them, click here.)

Electromagnetic Assessments

An essential and critical part of the picture of indoor health relates to electromagnetic radiation (EMR) that often permeates the modern indoor environment. Artificial EMR is to be distinguished from natural EMR (e.g.,  sunlight) as there has been a relatively sudden and massive increase of this artificial radiation in our environment* compared to the natural background radiation that existed until around the mid 20th Century, when the ubiqitous wireless technologies of today were at their inception.

 ( * = in the order of 1017times)

Needless to say, there is much evidence in the scientific literature that this artificial radiation is harmful to biological life forms. (e.g, see

Mould / Biological Assessment

The presence of mould in the indoor environment was initially shunned as harmless and merely a nuisance. However, the weight of empirical evidence (and of  human casualties to mould) has heightened the awareness of just how toxic and insidious this threat can be. Mould–being altogether comprised of the fungi’s spores, mycotoxins and secondary metabolites, can all harm human health in numerous, serious physical and psychological ways.

An evaluation of the presence of mould in any indoor environment is a must for a comprehensive assessment of the healthiness (or not) of any dwelling or contained habitable space.

Chemical Assessment

The US Environmental Working Group has evaluated that there are more than 90,000 declared chemicals that permeate our buildings, our furniture, our domestic products, and even our food, air and water supplies. Only around 3000 of these have ever been evaluated for their specific level of toxicity: and of this small fraction, an order of magnitude less is known about the synchronistic effects of these chemicals with each other, or with other naturally occurring volatile organic compounds (VOCs).

Hence the only way to deal with the plethora of chemicals that find their way into the home, office, leisure and automotive environments, is to assess the threat–and exercise the appropriate precautionary approach through avoidance, remediation, removal or neutralisation of offending products.

An Xtox evaluation of the environment for chemicals should be part of any serious approach to maintaining health, in this synthetic chemical age.
