Toxno is an Information Resource for Toxic Chemical Exposures and Resultant Health Consequences.

We investigate chemicals of concern like Heavy Metals and Pesticides. We source important data and visualise it. We collaborate with a world class laboratory (EAL) at Southern Cross University in Australia to test, publish de-identified innovatively visualised results online and research emerging chemicals of concern. We are passionate about raising awareness and our children’s future.

Science is only just beginning to grasp the combined effects of daily low dose toxic chemical exposures. It comes down to us, individuals, getting informed and acting at home and at the  community level to preserve human and animal health and wellbeing along with sustainability of our beautiful earth.

The World Health Organization (WHO) classify the heavy metals Lead, Arsenic, Cadmium and Mercury and one non-metal – excess Fluoride – amoung the top ten chemicals of major public health concern.

Hair Tissue Mineral Analysis (HMA or HTMA) in Australia

For the first time in Australia, human hair testing is available to the public using the absolute latest Perkin Elmer Inductively Coupled Plasma–Mass Spectrometer at Environmental Analysis Laboratories in Lismore, Australia. Instrument detection limits are at or below the single part per trillion (ppt) level for many of substances tested. Results are then presented online without any personal details - hence preserving privacy and confidentiality. Many innovative features are utilised so that individuals can get the outmost from their results. Example results are on this page. It's also a great way for children to get screened for heavy metal exposure like antimony, lead and mercury because of the non-invasive nature of the test.

Mercury (Hg): Exposure Routes and Health Effects

Mercury bio-accumulates in human brain, the food chain and the environment and is highly toxic. Pregnant-to-be woman, the elderly and children, especially developing foetuses and infants, are particularly vulnerable to mercury. Here we demonstrate that mercury exposure occurs through multiple routes and that individuals can reduce significant exposure from sources like artisanal gold mining, fish consumption and proximity to mining activities.

Sources of Lead (Pb) Exposure – Update 2019

This article gives a comprehensive list and explanation of possible exposures to the heavy metal, LEAD (Pb). Lead is a neurotoxin and has been known to cause brain damage and reduced cognitive capacity, especially in children. Lead exposure can result in nephropathy, as well as blood disorders such as high blood pressure and anemia. Lead also exhibits reproductive toxicity and can results in miscarriages and reduced sperm production. Lead is absorbed following inhalation, oral, and dermal exposure. It is then distributed mainly to the bones and red blood cells.

Sources of Arsenic Exposure

This article gives a comprehensive list and explanation of possible exposures to the heavy metal, ARSENIC (As) particluarly in Australia. This is an in-depth look at how we can be exposed to Arsenic. Most importantly, we look at ways to minimise this. This report is especially useful for those who have found levels in their body through pathology testing or the Toxtest/EAL Hair Analysis of toxic metals. This article will be updated as more information becomes available and complements all other Arsenic related information and tests on Toxno and Toxtest.

Sources and Health Consequences of CADMIUM Exposure

This article gives a comprehensive list and explanation of possible exposures to the heavy metal, CADMIUM (Cd). This is an in-depth look at how we can be exposed to Cadmium. Most importantly, we also look at how cadmium exposure can effect children and adult long-term health. This report is especially useful for those who have found levels in their body through pathology testing or the Toxtest/EAL Hair Analysis of toxic metals. This article will be updated as more information becomes available and complements all other Cadmium related information and tests on Toxno and Toxtest.

Silver (Ag): Exposure Routes and Health Effects

Silver is becoming more pervasive in our food, in dental and medical devices, in implants and even the cloths we wear. Silver forms silver-protein complexes when absorbed into the circulation and these become deposited in key soft tissues, including the skin, liver, kidney, spleen, lungs, and brain and at this stage must be presumed to present a health risk to exposed persons under some circumstances. Here we show ways we are increasingly exposured to silver and as such help us develop stratagies for avoidance and minimisation so as to reduce possible harm. This report is especially useful for those who have found levels in their body through pathology testing or the Toxtest/EAL Hair Analysis of toxic metals. This article will be updated as more information becomes available.

Soil remediation after glyphosate devastation

This is a 2019 update of an our article demonstrating simple soil remediation strategies and techniques after heavy applications of weed killer (glyphosate) in a residential backyard. Growing Health Food - but wait... after moving in to a house in 2016, I soon realised that the entire garden bed had been sprayed with weed killer. Everything was dead and a quick call to the real estate agent and a confirmation chat with their handy man revealed that indeed Roundup (Glyphosate) was heavily sprayed so as to avoid manual weed pulling. Here is the unfolding of the story in pictures...

Problems with Pesticides – a Toxno slideshow

Pesticides kill. That’s why we created them. Little combat chemical molecules that wage war on plants, worms, insects, rats or bugs. How is increasing human exposure to pesticides affecting health (especially children and future generations)? Are current models of pesticide use and production conducive for sustained food production? Is the all-important rich biodiversity of soil microbial life being decimated? Are regulations that are designed to protect us from harmful toxic chemical exposures adequate? Are current toxicology risk assessment models out of date in the current climate of multiple chemical exposures? Most importantly – what can we do as individuals and a community.

Toxtest and Environmental Analysis Laboratory (EAL)

Toxtest works with the Environmental Analysis Laboratory (EAL) in Lismore, NSW to provide extensive Toxic Chemical Testing. Results are then visualised and put in context to your health & any environmental contamination according to multiple safety based guidelines. No stone is left unturned. Our Home, Garden, Farm, Workplace, School and Recreation Area can be tested for nasty chemical build-up. We look at Air, Water, Soil, Compost, Dust and Human & Animal Hair.

Testing DUST in your home, workplace or school for heavy metals like Lead, Arsenic, Cadmium and Antimony

Dust allows nasty chemicals to bind to it. Adults, but more particularly children, are at risk of dangerous chemical exposure if dust in the home or workplace becomes contaminated with heavy metals. There are many ways this happens. This article provides details for a simple, inexpensive home or workplace test from one of the highest quality Environmental Analysis Laboratories in Australia (EAL) and outlines evidence of heavy metal dust contamination, the importance of getting tested and what to do about it.

heavy metal testing, visualisation services and raising public awareness


Toxno, Toxtest and Environmental Analysis Laboratory (EAL) at Southern Cross University in Lismore, NSW, Australia, collaborate to provide innovation and an Australian first in hair, water, soil/compost or dust testing of 32 heavy metals and minerals. Our Hair analysis (also called Hair Tissue Mineral Analysis (HMA or HTMA)) is AU$98. Order forms can be downloaded below.

All results are published (de-identified) online and updated regularly as new health or exposure route information becomes available for each metal/mineral. All results are dynamic, contain instructions, have full support and contain clickable links to current health and exposure information for each metal/mineral.

Hair results are live and use innovative moving graphical visualisations, while our water and soil analyses concurrently visualise your results based on human, animal and agricultural guidelines - a true Australian innovation. See a large list of example Hair, Water, Soil and Dust results.

Download test order forms here. Each test covers MERCURY, CADMIUM, LEAD, ARSENIC plus other Heavy Metals, Metaloids and Minerals (32 in total).
