Summary
Tire wear particles are a significant source of microplastic pollution. A new system dynamics model helps evaluate mitigation strategies, considering environmental, safety, and CO2 impacts for effective policy-making.
Area of Science:
- Environmental Science
- Microplastic Pollution
- System Dynamics Modeling
Background:
- Tire wear particles (TWP) are a primary source of microplastic emissions, posing environmental risks.
- Mitigation strategies for TWP are complex, involving trade-offs and potential unintended consequences.
- Effective evaluation requires models that consider multiple impact dimensions.
Purpose of the Study:
- To develop and apply a system dynamics model for predicting environmental TWP release.
- To evaluate the impact of various intervention strategies on TWP emissions and related factors.
- To provide a transferable framework for analyzing microplastic mitigation in different regions.
Main Methods:
- System dynamics modeling parameterized for the Netherlands.
- Integration of technical modeling with social dimensions (mobility, driving behavior).
- Literature review, expert consultation, and stakeholder engagement for model development and validation.
Main Results:
- The model successfully predicts environmental TWP release and evaluates intervention impacts.
- Incorporation of secondary indicators assesses broader consequences like road safety and CO2 emissions.
- Two policy scenarios demonstrate the model's utility in exploring system-wide effects and identifying effective interventions.
Conclusions:
- System dynamics offers a robust approach to analyzing complex microplastic challenges.
- The developed model provides a flexible tool for stakeholders to compare and evaluate TWP mitigation strategies.
- The methodology is transferable, offering a foundation for regional microplastic management.

Dalton was only partially correct about the particles that make up matter. All matter is composed of atoms, and atoms are composed of three smaller subatomic particles: protons, neutrons, and electrons. These three particles account for the mass and the charge of an atom.

5.8K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

02:10The Nucleosome Core Particle
14.6K
Nucleosomes are the DNA-histone complex, where the DNA strand is wound around the histone core. The histone core is an octamer containing two copies of H2A, H2B, H3, and H4 histone proteins.
The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...

A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...
