Asbestos Contaminated Soils and Health Risks
What is Asbestos and Why Is It Dangerous?
Asbestos is a naturally forming silicate mineral in the soil that is composed of tiny fibres. When it gets disturbed, it produces a dust that contains asbestos fibres. Breathing these asbestos fibers may cause a variety of health complications. However, it is only when the asbestos fibers are airborne that they pose a health hazard. Otherwise, when left untouched, asbestos does not necessarily become a health threat.
Who is at Risk of Asbestos Exposure?
A majority of persons who have developed asbestos-related ailments have typically worked in places or jobs where they were constantly exposed to asbestos and ended up breathing in large quantities of asbestos fibres. For instance, construction and farm workers may have in the past been employing unsafe practices.
What Diseases Are Caused by Asbestos Fibres?
- Mesothelioma: A cancer type that affects the pleura (lung covering), chest wall lining, and diaphragm. It can develop decades after exposure.
- Asbestosis: Progressive lung scarring that impairs breathing.
- Lung Cancer: Can also appear decades later. Smokers and those with asbestosis are more at risk.
- Pleural Plaques: Thickened scar patches on the lung lining.
How Are Governments Responding?
Governments worldwide are implementing measures to reduce the dangers of asbestos. For example, the Department of Health in Western Australia enforces the Health (Asbestos) Regulations 1992 under the Health Act 1911. These rules guide the removal, disposal, sale, and reuse of asbestos materials.
Bound Asbestos vs. Fibrous Asbestos: What’s the Difference?
| Type | Description | Risk Level |
|---|---|---|
| Bound Asbestos | Fibres are part of a solid material block, less likely to become airborne. | Low |
| Fibrous Asbestos | Loose fibres in soil, easily disturbed and inhaled when airborne. | High |
How to Manage Asbestos‑Contaminated Soils?
- Leave the soil completely undisturbed whenever possible.
- If movement is necessary, dampen soil to prevent fibres from becoming airborne.
- Ensure all site workers wear appropriate PPE (Personal Protective Equipment).
Are There Still Products Containing Asbestos?
Despite regulatory bans, older products containing asbestos are still in use in some regions, such as the US. Some newer products like vermiculite-based soil enhancers may still contain traces of asbestos.
