Introduction This introductory chapter presents the background to and the objectives of the study on Options for a strategic approach to pharmaceuticals in the environment, of which this report constitutes the first deliverable. 1.1.Background to the study Health care as practised in the European Union (EU) heavily relies on the consumption of pharmaceuticals, as reflected by the continuous growth of the European market for medicines for human and veterinary use. The EU is even considered the second biggest consumer in the world after the United States of America. While the benefits of a responsible use of these substances for human health and veterinary care are recognised, there is, however, increasing concern over the potential adverse effects of these substances on the environment and on human health via the environment. It is now widely acknowledged that pharmaceuticals and their residues – including Active Pharmaceutical Ingredients (API), metabolites and transformation products – are emitted into the environment at different stages of their life cycle, from their production to their use to their disposal. A large body of literature1 reports the presence of pharmaceuticals in environmental compartments (e.g. surface and ground water, soils, biota) in different parts of the world, including the EU Member States. They are generally detected at low concentrations (e.g. in the range of sub ng/L to µg/L in the aquatic environment). The level and frequency of exposure of biota (e.g. plants, animals, bacteria) and humans to these substances and their residues is a key component of the risk they pose to human health and the environment, along with their inherent hazard level. Actual exposure can be particularly complex to determine, because of the multiplicity of sources of emissions and contamination pathways (diffuse contamination, point source pollution from sewage networks or landfill leachates) as well as transformation and transfer processes in different environmental compartments. Another challenge lies in assessing the potential effects on the environment and human health of chronic exposure to low doses of mixtures of pharmaceuticals. In the EU, the issue of pharmaceuticals in the environment is to some extent addressed in the chemicals (including pharmaceuticals), industrial emissions, water, waste and food legislation. Most do not include specific provisions for pharmaceuticals, but can be applicable to the issue. The present study is part of the effort to develop the EU strategic approach for pharmaceuticals mentioned in Directive 2013/39/EU,2 which is likely to take the form of a Commission Communication. This approach must allow coordinating and balancing efforts across Member States and categories of stakeholders towards: better knowledge of the issue (e.g. through fostering research and adequate monitoring and reporting activities); more sustainable production, consumption and disposal patterns;
