The application of the DAPSI(W)R(M) framework to the plastic pellets chain
AI summary Read the abstract
The DAPSI(W)R(M) framework — a structured approach to environmental problem assessment — was applied to analyze the full chain of impacts from plastic pellet (nurdle) production and release into the environment. The analysis traced pressures, state changes, welfare impacts, and management responses for this widespread microplastic contaminant. This framework helps identify the most effective points for intervention to reduce plastic pellet pollution.
Single-use plastic, few global engagement and lack of policies contribute to the global challenge about plastic marine litter. This form of contamination can cause injury and death of marine wildlife. Microplastics (>5 mm) represent an important fraction of plastic litter. They include the plastic pellets that are used as raw material within plastic industry that can be unintentionally spilled into the environment during the industrial processes. In an initiative in order to facilitate the understanding and communication of plastic pellets as a social and environmental problem, we applied the Drivers-Activities-Pressures-State changes-Impacts (on Welfare)-Responses (as Measures) (DAPSI[W]R[M]) framework to plastic pellets chain. We also analyzed possible mitigating measures and their actions along the plastic pellets chain. This DAPSI(W)R(M) framework aim to show an overview of the plastic pellets chain and solutions for politicians and decision makers to help solve this socio-environmental problem that needs the engagement of all stakeholders involved.

Microplastics in the environment: A DPSIR analysis with focus on the responses
AI summary Read the abstract
This review applies a DPSIR (driving forces, pressures, states, impacts, responses) framework to organise current knowledge on microplastic pollution, covering sources, distribution across environmental compartments, and socio-economic impacts. The authors assess available response strategies including regulatory instruments, biodegradable plastics development, wastewater treatment, and environmental cleanup, while identifying key gaps in the literature.
Microplastics: An analysis using the DPSIR (Drivers, Pressures, State, Impacts, Responses) model: The situation of Brazil
AI summary Read the abstract
This review applies the DPSIR (Drivers, Pressures, State, Impacts, Responses) framework to analyze microplastic pollution specifically in the Brazilian context, structuring available evidence on sources, environmental accumulation, ecological and human health impacts, and current policy and technological response measures. The authors aim to provide a structured evidence base to guide large-scale solutions to microplastic pollution in Brazil.
The Marine Plastic Litter Issue: A Social-Economic Analysis
AI summary Read the abstract
Using the DPSIR framework, this study analyzed marine plastic litter pollution as a social-economic issue, finding that fewer than 10 peer-reviewed studies had applied this policy-relevant analytical model to ocean plastics, and identifying management response gaps in food security, transport, and shelter contexts.
A Pro-Environmental Value Construct to Deal With Plastic Pollution
AI summary Read the abstract
This article proposes a value-based framework for understanding plastic pollution, analyzing how the widespread usefulness of plastics drives their overuse and improper disposal. The author argues that sustainable solutions require rethinking the full lifecycle of plastics — from production through end-of-life — with a particular focus on reducing the microplastic contamination entering food chains.
