The Discovery of Asbestos in Mulch

In Sydney, bonded asbestos was first identified in mulch at Rozelle Parklands and subsequently near electrical substations and along a highway strip. This prompted the closure of the newly-opened park and an ongoing investigation by the NSW Environment Protection Authority (EPA). The source of the asbestos and the responsibility for its inclusion in the mulch are still under investigation​ (referenced from Famanz)​.

Melbourne has also faced similar issues, with asbestos detected in mulch at a playground, leading to concerns about children’s exposure. This discovery has not only caused alarm among parents and local residents but also prompted reviews of mulch sourcing and testing procedures​ (reference from Famanz)​.

Health Implications and Public Safety

Bonded asbestos, when intact and undisturbed, generally poses a low health risk. It becomes a concern when the material is damaged, deteriorating, or disturbed, which can release harmful asbestos fibres into the air. Health authorities emphasise that the risk to the public from the asbestos found in mulch is currently considered low, as long as the material remains undisturbed​ (referenced from Famanz)​.

However, the presence of asbestos in mulch underscores the potential for exposure, especially if the material is used in environments frequented by vulnerable groups, such as children. Authorities have stressed the importance of monitoring and managing these risks, particularly in public spaces.

Ongoing Investigations and Actions

The EPA has issued Clean Up Notices to ensure the removal of contaminated mulch from affected sites and prevent further use of the implicated products. The investigations are extensive, involving the mulch supply chain and potential sites of asbestos contamination​ (referenced from Famanz)​.

In response to these events, regulatory bodies are taking steps to enhance testing protocols and tighten regulations around recycled mulch products. The incidents have sparked a broader discussion about the management of asbestos in Australia, where its use in construction was extensive in the past.

Recommendations for the Public

While the risk from the newly discovered contaminated mulch is being managed, the general advice for the public is to remain informed and cautious. Individuals purchasing mulch for personal or commercial use should inspect the material for any unusual components and consult suppliers about the safety and testing of their products​ (referenced from Famanz)​.

The recent findings serve as a reminder of the ongoing challenges posed by asbestos in the environment. It highlights the need for stringent safety standards and robust regulatory frameworks to protect public health from asbestos exposure, especially in recycled products.
