REACHing for divergence?—UK chemical regulation post-Brexit
Summary
This paper is not directly about microplastics; it analyzes how UK chemical regulation has diverged from EU REACH standards since Brexit, finding that the UK is falling behind the EU's pace of regulatory action on hazardous chemicals. While broadly relevant to environmental protection, the study does not address microplastics specifically.
On 1 January 2021, the United Kingdom formally exited the European Union (EU; Brexit) and ceased to be subject to EU chemical regulation requirements. Before Brexit, UK chemical policy was regulated largely by the EU. With its large internal market, sophisticated regulatory capability, and stringent regulatory framework, the EU has become the world's leading regulatory state, regularly influencing global industrial decisions and practices. At the time of writing, there has been limited academic analysis of the implications of Brexit for UK chemical regulation. More than two years post-Brexit, we have the opportunity to assess UK chemical regulation and revisit early expectations about regulatory divergence. This article takes the EU's Regulation on the Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) as a case study to analyze patterns of post-Brexit regulatory divergence, thereby providing one of the first analyses of the implications of Brexit on UK chemical regulation. Through the analysis and review of key documents and reports (n = 99), this article assesses the extent to which UK and EU regulatory (REACH) regimes are beginning to diverge and discusses the potential implications of any divergence for the United Kingdom. We find that the UK and EU chemical regulatory regimes are now evolving independently and provide clear, empirical evidence of an emerging divergence in regulatory decisions, ambitions, and approaches. The evidence suggests that the United Kingdom is currently unable to keep pace with EU developments, lacking the capacity, expertise, and capability of its EU counterparts, raising the prospect of further divergence in the future.

Assessing and managing environmental hazards of polymers: historical development, science advances and policy options
Researchers critically reviewed how polymer environmental safety regulations, largely unchanged since the 1990s, fail to keep pace with scientific understanding of plastic pollution. They identified four key areas needing regulatory attention, including better transparency about polymer identities, improved understanding of environmental fate across size categories, and more comprehensive hazard assessments. The study suggests that current regulatory frameworks worldwide need significant updates to adequately manage the environmental risks posed by polymers.
An Examination of Evolving Concerns, Obstacles, and Prospects in Relation to Pollution in the Marine Environment
This review examines international and national regulatory frameworks for marine pollution, finding that laws are often reactive — triggered only after environmental disasters — and inadequate for addressing diffuse threats like microplastic contamination. The authors argue that current legal tools need modernization and stronger enforcement to keep pace with emerging pollutants. This is relevant context for understanding why microplastic regulation lags far behind scientific evidence of harm.
The emergence of microplastics: charting the path from research to regulations
This study summarized recent groundbreaking microplastic research and emerging regulations, charting the path from scientific discovery to policy action and providing recommendations to overcome remaining regulatory barriers.
La Révision de REACH : Quels Impacts sur la Santé Humaine, l'Environnement et l'Industrie Attendus?
This study examines the anticipated impacts of the revision of the European REACH regulation on human health, environmental protection, and industrial practices. The analysis addresses how updated chemical regulations are expected to affect the management of hazardous substances including plastic additives and pollutants across the value chain.
On the issue of microplastics in the environment
This paper examines the origins of microplastic pollution, arguing that its emergence is not solely attributable to polymer chemistry advances and cannot be explained simply by physicochemical degradation processes acting on plastic materials.
