  • DESCRIPTION: Toxtest is collaborating with EAL to bring to the public a means to test soil. Most importantly we are presenting the results using creative visualisation techniques that enable you to get the most from the results.

    High levels of metals, metalloids and asbestos can be associated with ore bodies. Soils in mining areas may contain elevated levels of these materials due to natural mineralisation. Some urban areas may be affected by asbestos and various elements including lead, copper, zinc, cadmium and arsenic from the ore bodies, as well as activities associated with historical build up, mining, smelting and metallurgical industries.

    Public information about preventing exposure to mineralised or contaminated soil is an essential component of public health programs to minimise community exposure to these contaminants.

    Health investigation levels (HILs) have been developed for a broad range of metals and organic substances. The HILs are applicable for assessing human health risk via all relevant pathways of exposure. The HILs are generic to all soil types and apply generally to a depth of 3 m below the surface for residential use. Site-specific conditions should determine the depth to which HILs apply for other land uses.

    HILs are scientifically based, generic assessment criteria designed to be used in the first stage of an assessment of potential risks to human health from chronic exposure to contaminants. They are intentionally conservative and are based on a reasonable worst-case scenario for four generic land use settings:

    HIL A residential with garden/accessible soil - home grown produce - 10 percent fruit and vegetable intake, (no poultry), also includes childrens day care centres, preschools and primary schools

    HIL B residential with minimal opportunities for soil access includes dwellings with fully and permanently paved yard space such as high-rise buildings and flats

    HIL C public open space such as parks, playgrounds, playing fields (e.g. ovals), secondary schools and footpaths. It does not include undeveloped public open space (such as urban bushland and reserves) which should be subject to a site-specific assessment where appropriate

    HIL D commercial/industrial such as shops, offices, factories and industrial sites.

  • "Visualization is critical to data analysis. While tables are necessary to record the data, it is usually very difficult to distinguish pattern in tables of numbers, particularly for large data sets. Graphs, however, allow the reader to see complex data sets simply and concisely. Plots can reveal hidden structure in the data, and outlying or unusual results, and they enable preconceived ideas to be challenged."

  EXAMPLE RESULTS

The US EPA result is a good example of how individual heavy metal visualisations look different using different guidelines. In particular check out Lead, Cadmium, Arsenic and Manganese under the different guidelines.

River soil (sediment) collected by the US EPA on 27th August 2015 after the Gold King Mine spill.

Tests are being updated regularly to include new exposures and their toxic substances. And NEW tests are introduced. You can unsubscribe at any time.


Metals and metalloids included in this test that are potentailly toxic to humans.

These are active links that take you to a full substance profile on Toxno. From there you can also see many healthy associations and known toxic effects. Note that chromium and manganese are also human nutrients.

Aluminium Antimony Arsenic Barium Beryllium Bismuth Cadmium Cobalt Chromium Lead Manganese Mercury Nickel Silver Strontium Thorium Uranium

Additional minerals also included in this test. These are also, all, human nutrients.

Note that high intake or exposure to levels of nutrients that go beyond the recommended upper intake levels can also be toxic and as such have adverse health consequences. Small children are especially vulnerable as they play in soil, often putting hand to mouth.
