Summary

Untreated industrial effluents may contain a wide variety of contaminants of potential concern for human health. This report groups contaminants into seven broad classes: endocrine disrupting compounds, heavy metals and metalloids, per- and polyfluoroalkyl substances, pharmaceuticals, pesticides, microplastics, and contaminants of specific concern for tikanga Māori. To determine the potential health risks posed by these contaminants in the Aotearoa New Zealand context, further analysis is required.
