- Climate change, biodiversity loss, and chemical pollution are planetary-scale emergencies requiring urgent mitigation actions. As these "triple crises" are deeply interlinked, they need to be tackled in an integrative manner. However, while climate change and biodiversity are often studied together, chemical pollution as a global change factor contributing to worldwide biodiversity loss has received much less attention in biodiversity research so far. Here, we review evidence showing that the multifaceted effects of anthropogenic chemicals in the environment are posing a growing threat to biodiversity and ecosystems. Therefore, failure to account for pollution effects may significantly undermine the success of biodiversity protection efforts. We argue that progress in understanding and counteracting the negative impact of chemical pollution on biodiversity requires collective efforts of scientists from different disciplines, including but not limited to ecology, ecotoxicology, and environmental chemistry. Importantly, recent developments in these fields have now enabled comprehensive studies that could efficiently address the manifold interactions between chemicals and ecosystems. Based on their experience with intricate studies of biodiversity, ecologists are well equipped to embrace the additional challenge of chemical complexity through interdisciplinary collaborations. This offers a unique opportunity to jointly advance a seminal frontier in pollution ecology and facilitate the development of innovative solutions for environmental protection.

Forskningsöversikt (refereegranskat)abstract
- Chemical pollution poses a threat to biodiversity on a global scale. This has been acknowledged in the Post-2020 Global Biodiversity Framework, which proposes to regulate the release of chemicals to the environment and names specific indicators focusing on pesticides, nutrients and plastic waste. We fully welcome the inclusion of these substances but would like to further emphasize that in order to protect biodiversity from hazardous chemicals, the scope of Target 7 should feature a wider range of pollutants that can contribute to biodiversity loss. We propose the inclusion of non-agricultural biocides, per- and polyfluoroalkyl substances (PFASs), toxic metal(loid)s, and endocrine-disrupting chemicals (EDCs). Furthermore, data on emerging pollutants (e.g., rare earth elements, toxic and persistent industrial chemicals, liquid crystal monomers, pharmaceuticals, personal care products) need to be regularly reviewed with the aim to integrate additional pollutants to Target 7 in the case of biodiversity risk. We suggest to amend Target 7 to postulate the aim for the overall reduction of chemical production and emissions, as well as the addition of the aforementioned substance groups of high concern to biodiversity for integration in the Post-2020 Global Biodiversity Framework. We further elaborate on different strategies for the reduction of emissions of hazardous chemicals through chemical simplification and grouping, reduction of chemicals with non-essential use, and innovative synthesis strategies (e.g., “benign-by-design”). In this context, the full life cycle of chemicals (i.e., production, use, and end of life) needs to be considered. Lastly, we propose to set up transparent data inventories, in cooperation with the industry, to inform about the production, transport and emissions of chemicals, which can serve as a basis for indicators related to monitoring the progress towards achieving the goals set under Target 7.
