A mini-review on plasticrusts: occurrence, current trends, potential threats, and recommendations for coastal sustainability
AI summary Read the abstract
This review describes a newly identified form of plastic pollution called plasticrusts, which are plastic coatings that form on rocks along shorelines from crushed plastic debris. These formations can release microplastics into the marine environment as they break down and may introduce harmful chemicals into coastal food chains. The discovery highlights that plastic pollution takes more forms than previously recognized, potentially increasing the ways microplastics enter the environment and, eventually, human food sources.
Plasticrusts manifest as a coating on intertidal rocks due to environmental exposure. They refer to crushed plastic debris that blankets rocks found along intertidal shorelines. This study significantly contributes to a better understanding of the occurrence of these novel plastic formations, shedding light on their potential pathways of formation during the Anthropocene era. The research provides comprehensive insights into the composition, origins, challenges, and effective management strategies for removing coastal plastic litter. The findings of this investigation offer valuable evidence regarding the formation and impact of these recently discovered plastic items in coastal regions, prompting discussions about their formation processes and their effects on the marine ecosystem. Recognizing that these newly emerged plastic litter pose a considerable threat to the marine environment is crucial. With their emergence, we face an environmental challenge, especially concerning the health of coastal ecosystems. Plasticrusts, when degraded, can release microplastics (MPs) and nanoparticles (NPs) into the surrounding environment. These micro- and nano-sized plastic particles pose significant ecological risks as they persist in ecosystems, potentially harming wildlife and entering the food chain, causing widespread environmental contamination. Significantly, it outlines strategies to minimize the impact of this emerging plastic debris and its source.

Researchers tracked the full lifespan of "plasticrusts" — thin plastic coatings fused onto intertidal rocks in Japan — from formation through degradation, finding that wave action and scraping during beach cleanups generate these crusts, which then fragment and contribute microplastics to coastal environments, with their fate determined by whether the polymer floats or sinks.
Plasticrusts, plastiglomerate and pyroplastic: new connections among novel plastic forms
AI summary Read the abstract
Plasticrusts, plastiglomerates, and pyroplastics are newly identified forms of plastic that have fused with rocks, sand, or other natural materials along marine coastlines worldwide. These novel plastic forms are created through weathering, burning, and melting processes and represent a largely unstudied pathway for microplastic generation. Their discovery shows that plastic pollution is transforming coastal environments in ways scientists are only beginning to understand.

First record of plastiglomerates, pyroplastics, and plasticrusts in South America
AI summary Read the abstract
Researchers documented the first evidence of plastiglomerates, pyroplastics, and plasticrusts on beaches in South America, adding to the growing global record of these newly described forms of plastic pollution. The study suggests that these formations, where plastic fuses with natural materials like rock and sediment, represent a lasting geological marker of human plastic pollution in coastal environments.
