Summary: Agricultural soils and microplastics are major hotspots for antibiotic resistance genes (ARGs), with plastic mulch being the main source of microplastics in agricultural soil. This study used metagenomics to investigate the distribution patterns of ARGs and mobile genetic elements (MGEs) in eight Chinese provinces with a long history of plastic mulch use. The results identified 204 subtypes of ARGs and thousands of MGEs, with multidrug resistance genes being dominant. Regions with a longer history of plastic film use had a higher abundance of ARGs and MGEs, and a modular network distribution pattern of ARGs and MGEs was observed.

Summary: The presence of microplastics in soil is increasing globally. However, the effects of soil microplastic contamination on soil health indicators vary. It can either increase or decrease the trend of physicochemical and biological soil properties, and in some cases, it has no impact. The alteration of soil health properties by microplastics is influenced by factors such as microplastic concentrations, types, soil mechanics, and microorganisms.

Summary: Agricultural soils play a significant role in the reservoir of antibiotic resistance genes (ARGs) that are closely related to human health through the food supply. This study investigated the impact of soil aggregates on the distribution of ARGs. The results showed that manure application and aggregate size individually influenced the distribution of soil ARGs, with manured soils having more diverse and abundant ARGs. The <53 μm aggregate size fraction exhibited the highest diversity and abundance of ARGs. Soil traits, mobile genetic elements, and bacterial community collectively contributed to the variation of soil antibiotic resistance.

Summary: The study found variations of heavy metals, antibiotic resistance genes (ARGs), mobile genetic elements (MGEs), and microbiome in the soil surrounding a phosphorus chemical industrial zone. The primary factors controlling the distribution of ARGs were cadmium (Cd) and MGEs levels, with a stronger direct effect of Cd on ARG abundance compared to its indirect effect.

Summary: This study investigated the distributional characteristics of soil microplastics in three different farmland-use types across three soil layers in the main agricultural and pastoral areas around Urumqi, China. The results showed that most microplastics were white films with sizes of 0.2-0.5 and 0.5-1.0 mm, mainly derived from the damage to residual mulches. The abundance of microplastics was highest in greenhouse plots, followed by vegetable plots and crop fields. Microplastics can migrate to deeper soil layers and are influenced by tillage disturbance. The study provides important data for further research on microplastics in arid terrestrial ecosystems and policymaking on their management.

Summary: This study found that bacteria from different sources, polylactic acid microplastics, and florfenicol had positive effects on the growth of C. pyrenoidosa and increased its chlorophyll content. The presence of these bacteria in the phycosphere was significantly influenced by their sources and the addition of polylactic acid microplastics and florfenicol. Moreover, polylactic acid microplastics and florfenicol also promoted the abundance of phenicol-related antibiotic resistance genes in the phycosphere, indicating that exogenous pollutants can facilitate the spread of antibiotic resistance genes in the environment.

Summary: This paper comprehensively reviews the interaction between microplastics (MPs) and antibiotics (ATs), focusing on the role of biofilm developed MPs. It summarizes the formation process and unique microbial community structure of microplastic biofilm, and discusses the mechanisms by which microplastic biofilm drives the production and enrichment of antibiotic resistance genes (ARGs). The transfer pathways of ARGs affected by microplastic biofilm are outlined, with horizontal gene transfer (HGT) being the main mode of transmission. The ecological implications of the interaction between microplastic biofilm and ATs, as well as perspectives for future research, are also reviewed.

Summary: The extensive use of antibiotics has led to the accumulation of antibiotic-resistant microorganisms and genes in environments, posing a threat to human health and environmental contamination. In this study, the effects of five years of nematicide avermectin application on the rhizosphere microbiome and resistome of sick tobacco plants were investigated. The application of avermectin increased the abundance and distribution of antibiotic-resistant bacteria and resistance genes in the soil.

Summary: The study investigated the aging characteristics of four commonly used polymers under UV irradiation and provided insight into the impact of UV exposure on the physical and chemical properties of the polymers. Various analytical methods revealed the significant effects of UV irradiation on the crystalline and thermal properties of the polymers, as well as the formation of new functional groups. It was also found that UV exposure altered the ratio of low molecular weight compounds to higher molecular weight hydrocarbons and impacted the reliability of microplastic quantification in real samples.

Summary: The interest in the effect of microplastics on the terrestrial environment has increased recently. Different studies have shown different effects on earthworms, depending on the properties of microplastics in the environment and exposure conditions. This study found that low-density polyethylene microplastics did not cause death or significant effects on the growth and reproduction of earthworms within a short exposure period. However, ingestion of microplastics and damage to the earthworm skin suggest potential adverse effects on growth after longer exposure.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
