Additional Environmental Monitoring Underway at Key Industrial Sites in Tasmania
01 Oct 2025
Lead has previously been found in soils in Lutana and Rosebery, with studies over 15 years ago noting elevated metal levels in some locations. Earlier assessments concluded there was no evidence of harm to local communities.
EPA Director Catherine Murdoch said recent investigations at Rocherlea in 2024 prompted a review of monitoring methods for lead dust emissions from the Nyrstar zinc smelter in Hobart and the MMG mine in Rosebery. Initial sampling began in December 2024, focusing on dust deposited near both facilities.
Lead has been detected in dust near Nyrstar in Lutana and across the river on the Eastern Shore, as well as near the MMG mine in Rosebery. Independent consultants have been engaged to conduct extensive environmental monitoring and human health risk assessments in these areas.
“This work will be carried out with the Department of Health’s Public Health Services and WorkSafe Tasmania, to help reassess any potential human health risks,” Ms Murdoch said.
WorkSafe Tasmania continues to monitor worker safety at both facilities. Each site is required to control dust emissions, and current monitoring shows compliance with existing standards.
Director of Public Health, Dr Mark Veitch, said the Department of Health is providing precautionary advice to residents in areas historically known for higher metal levels, including parts of Lutana, Geilston Bay, northern Lindisfarne, and Rosebery township. A map of affected areas is available on the EPA website.
Dr Veitch emphasised practical steps to reduce lead exposure, particularly for children:
-
Wash and dry hands before eating, drinking, or smoking.
-
Maintain a healthy, balanced diet to reduce lead absorption.
-
Take care when gardening, especially if growing fruit, vegetables, or keeping poultry.
-
Test paint for lead before renovations; lead test kits are available at hardware and paint stores.
