However, using rubber mulch may feel a bit like choosing between two evils. It catches fire more easily and once it burns the resulting fire is hotter and faster. Rubber mulch is also much more flammable than wood mulch. Heavy metals, VOCs like toluene, and polycyclic aromatic hydrocarbons – all of which may be found in crumb rubber – have been linked to cancer.

The effects of exposure in humans may range from skin and eye irritation to neurological and organ damage. Zinc may already be present in the soil, and by adding rubber mulch you can raise the levels. Zinc, for example, is good for plant growth as it produces chlorophyll, but too much of it can cause toxicity in plants. While small doses of certain chemical elements may not pose a problem, and can even be good for us, overexposure can lead to negative effects. This is particularly the case when it comes to children if they’re regularly exposed to rubber mulch by being out and about on the playground every day.Īdditionally, children are more vulnerable to toxic exposure because their bodies are still developing and they are prone to putting their hands, as well as foreign objects, in their mouths. It’s worth being aware of the risks of using rubber mulch, especially as some toxins can build up in our bodies, as well as in water or soil. Rubber mulch may also contain trace elements of heavy metals like lead and manganese, while also off-gassing volatile organic compounds (VOCs). Not exactly something you want to come across on public playgrounds with children. While we may be exposed to these in many other areas of life – including in our food – their presence in rubber mulch can lead to increased and more regular exposure. Chemical elements like aluminum, cadmium, copper, iron, magnesium, selenium, sulfur, and zinc have all been found in rubber mulch.
This question leads to quite a knotty answer and it is evident that further questioning and more research are required.
Let's explore the sustainability of these rubber chips and explore some non-toxic mulch brands. This is especially concerning when used in playgrounds where it may affect young children who are more vulnerable to toxins in the environment. But rubber mulch has been attracting attention of a different kind, as consumers have begun to question the toxicity of rubber mulch. When it comes to landscaping it provides many benefits for plants because it retains moisture, discourages weed growth, and does not attract pests.Īnd since it does not rot or break down quickly, it needn’t be replaced regularly.Īll these advantages have led to its popular use.
