Since the objective of this Regulation, namely to ensure a high level of protection of human health and the environment from anthropogenic emissions and releases of mercury and mercury compounds, by means, inter alia, of a mercury and mercury-added product export and import prohibition, of restrictions on mercury use in manufacturing processes, products, artisanal and small-scale gold mining and processing and in dental amalgam, and of obligations applicable to mercury waste, cannot be sufficiently achieved by Member States, but can rather, by reason of the transboundary nature of mercury pollution and the nature of the measures to be taken, be better achieved at Union level, the Union may adopt measures in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty on European Union.
