Emerging organic contaminants
Emerging organic contaminants (EOCs) are natural or manufactured chemicals, some of which are commonly found in household and personal care products, pharmaceuticals and agrichemicals. The use and discharge of EOCs are poorly understood and largely unmonitored in Aotearoa New Zealand but they can pose a risk to our biodiversity, land-based food production and processing, and our fishing and aquaculture industries. There is increasing concern about the potential of EOCs to threaten the health and well-being of our people and unique ecosystems.
Despite increasing amounts of EOCs being released into the environment, there is limited information on their risks, mainly because their impacts are associated with long-term exposure, rather than immediate acute effects. However, in recent years regulators, the food industry, Māori and the wider community have become increasingly concerned about the risk EOCs can pose to human and ecosystem health.
This project was developed to assist Aotearoa-NZ with the overarching vision: Whakahaumarutia to tātou taiao i te aranga ake o ngā tāwahawaha kikino – A healthy Aotearoa New Zealand safeguarded against emerging contaminants
The aims of the research are to identify EOCs that pose highest risks to New Zealand’s ecosystems, their potential to accumulate in food, and their role in the development of antimicrobial resistance.
The multi-disciplinary team of toxicologists, chemists, microbiologists, social scientists are working in partnership with iwi, the wider community, environmental managers and policy makers to develop solutions. A National Advisory Panel oversees the progress of the research and ensure that it remains focussed on key concerns. A National Strategy to manage EOCs was developed to minimise the risks of EOCs in New Zealand to safeguard our people from their harmful impacts and ensure that our food export products continue to meet trade requirements.
