From passive carriers to selective filters: how microplastic aging shapes antibiotic resistance gene abundance
AI summary Read the abstract
This is a dataset, not a study with new findings. It compiles 701 data points from existing research on how aging of microplastics in the environment relates to the abundance of antibiotic resistance genes, including details on microplastic types, aging conditions, and study measurements.
This dataset contains the complete extracted data used in the meta-analysis of the effects of microplastic aging on antibiotic resistance gene abundance. It includes 701 observations, comprising 382 observations for relative ARG abundance and 319 observations for absolute ARG abundance. The dataset includes publication information, ARG-related information, microplastic characteristics, aging conditions, environmental matrices, summary statistics for unaged control and aged treatment groups, and calculated natural-log response ratios (lnRR) with their sampling variances. The files include the supplementary dataset in CSV and XLSX formats, together with a data dictionary describing the variables. The dataset was compiled and prepared by Qing Zhu, Yifei Wang, Xinyi Wang, Zhihui Jin, Ping Gong, Ming Yuan, and Huaiying Yao.

Dataset for "From passive carriers to selective filters: how microplastic aging shapes antibiotic resistance gene abundance"
AI summary Read the abstract
This is a dataset, not a new study. It contains 701 data points collected from existing research on how aging of microplastics (breakdown from weather, sunlight or other exposure) relates to levels of antibiotic resistance genes, including details on the plastics, aging methods and test settings used.
From passive carriers to selective filters: how microplastic aging shapes antibiotic resistance gene abundance.
AI summary Read the abstract
An analysis combining 701 studies examined how "aging" (weathering) of microplastics affects the amount of antibiotic resistance genes found on them. As microplastics aged, resistance gene levels first rose, peaking around 15 days, then changed over time, suggesting aged plastics may act as selective habitats for these genes rather than just carrying them.
Aged Microplastics and Antibiotic Resistance Genes: A Review of Aging Effects on Their Interactions
AI summary Read the abstract
This review explores how the aging of microplastics in the environment affects their ability to harbor antibiotic resistance genes. Researchers found that weathering processes like sunlight exposure increase the surface area of microplastics and generate reactive oxygen species, both of which can enhance the uptake and transfer of resistance genes among bacteria. The findings suggest that aged microplastics in the environment may be more effective at spreading antibiotic resistance than fresh ones.
Effects of aged microplastics on the abundance of antibiotic resistance genes in oysters and their excreta
AI summary Read the abstract
Researchers studied how aged microplastics affect the abundance of antibiotic resistance genes in oysters and their excreta. The study found that microplastics can serve as carriers for antibiotic resistance genes in filter-feeding organisms, potentially exacerbating the spread of antibiotic resistance in aquaculture environments where plastic contamination is widespread.
Microplastics act as vectors for antibiotic resistance genes in landfill leachate: The enhanced roles of the long-term aging process
AI summary Read the abstract
This study examined whether the aging of microplastics in aquatic environments influences their role as vectors for antibiotic resistance genes (ARGs). Aged microplastics showed different ARG enrichment patterns on their surfaces compared to pristine particles, suggesting that weathering changes the capacity of plastic debris to accumulate and spread antibiotic resistance.
