Vertical distribution and multi-source pathways of microplastics in agricultural soils: A study of typical irrigation areas in the upper Yellow River basin

Researchers found that farmland soil in the upper Yellow River region contained significantly more microplastics than nearby forest or grassland, with plastics detected in all soil layers down to one meter deep. Flood-style irrigation pushed microplastics much deeper into the ground than drip irrigation, doubling contamination levels. This is concerning because microplastics migrating deep into agricultural soil could eventually reach groundwater that people depend on for drinking water.

A review of the migration mechanisms of microplastics in terrestrial environments

This review maps out how microplastics move through land-based environments via wind, water, gravity, and biological processes like animal ingestion and plant uptake. The paper categorizes movement mechanisms as physical, chemical, or biological, and identifies key factors like particle size and shape that determine where microplastics end up. Understanding these migration pathways is essential for predicting how microplastics in soil can reach water supplies and the food chain.

Research status and prospects of microplastic pollution in lakes

This review systematically covers microplastic pollution research in lakes, including sampling and identification methods, distribution patterns, ecological effects, and knowledge gaps, identifying lakes as important but understudied sinks for microplastic contamination.

Environmental Value and Pro-environmental Behavior Among Young Adults: The Mediating Role of Risk Perception and Moral Anger

A survey of 558 young adults tested the relationship between environmental values and pro-environmental behavior, finding that risk perception and moral anger acted as mediating mechanisms through which values translated into action. The study provides insights for environmental communication strategies aimed at motivating plastic pollution reduction behaviors in younger populations.
