Emerging organic contaminants (EOCs) are natural or manufactured chemicals, many of which are found in common household and personal care products, pharmaceuticals and agrichemicals.
Despite increasing amounts of these chemicals being released into the environment, their use and discharge is still largely unregulated, mainly because their effects are associated with long-term cumulative exposure, rather than immediate effects. In recent years however, regulators, the food industry, Māori and wider community networks and the international science community have become increasingly concerned about the risks EOCs can pose to human and ecosystem health.
Starting in 2018, this 5-year programme aims to identify which EOCs are predominant in New Zealand’s aquatic ecosystems and to characterise the risks they pose to our unique taonga. Their potential for accumulation in food and the role EOCs play in the development of antimicrobial resistance will also be investigated. The project has a strong focus on Iwi, community, policy, industry and stakeholder engagement to raise awareness, and to support informed discussion and the design of practical strategies to better manage the risks and impacts of EOCs in New Zealand.
The multi-disciplinary team of toxicologists, chemists, microbiologists and social scientists will work in partnership with iwi, key community stakeholders, environmental managers and policy makers in two case-study/catchment sites: the Whau River (Auckland) and the Mataura River (Southland). The structure of the programme includes a National Advisory Panel to oversee the progress of the research and ensure alignment with the National Strategy document on emerging contaminants. This work aims to enhance regional and national frameworks for managing the risks of EOCs in New Zealand, to safeguard our people and natural environments from their harmful impacts, and ensure that our food export products continue to meet all necessary trade requirements.
